Projects tackled memory loss, data protection, mental health and more

After successfully reinstating San Francisco State University’s in-person hackathon last year, SF Hacks kept the momentum rolling by jumping into planning their 2025 event and making it bigger and better. 

On April 4 – 6, 300 hackers convened at SFSU’s Annex 1 for the annual SF Hacks hackathon. Participants came from all over the country, with over 80% coming from all over California and 30% returning from SF Hacks 2024. The attendee number jumps to 430 when considering volunteers, judges, mentors and more. The event almost hit the venue limit on the first day.

At its core, SF Hacks is a 48-hour hardware and software building competition, but that description doesn’t fairly encapsulate the event. It is really a community affair with mini events, panels, workshops, professional and social networking, fun activities like Bob Ross painting and tennis, complimentary food … and it’s a totally free event to boot.

“Of course, we have the innovation aspect that is with all hackathons. But something we feel is important and strongly about here at SFSU is our social activism,” said SF Hacks president Marco Garcia, a Computer Science sophomore, of this year’s “tech for good” theme. 

“With so many different ways to harness technology, it’s so important we have a guiding principle and that is to build for good,” said SF Hacks Director Ria Thakker during the opening ceremony, encouraging hackers to think more deeply about what it means to build for good. “What are your preferred use cases, whose perspectives you’re considering and how to utilize your knowledge to give back to your community."

One project that placed in several categories was a robot called Remi that helps people with memory loss. When Remi sees a familiar face, it recalls and shares details about that person to the user. An SFSU team won the Best AI Emerging Technology prize with their project Secure Sense. This project helps prevent information leaks by detecting and blocking or masking sensitive data when people use generative AI tools like ChatGPT or Gemini. 

Although it can be daunting, it’s rewarding to push yourself on your own terms to see what you can do, explained SF Hacks Sponsorship Chair Keith Curry, a senior double majoring in Computer Science and Biology. “We take all these courses and learn all these skills. But a lot of times, the curriculum doesn’t test the extent of our ability. It just tests our ability to adhere to a curriculum."

However, students don’t need to be experienced coders, or even computer scientists, to participate. There are tools and mentors available to help beginners learn technical skills. This year, SF Hacks also highlighted the cross-disciplinary collaboration needed to build projects, said SF Hacks Vice President Ashley Ching, a Computer Science senior.

“We tried to get many people outside of technical roles, like product managers, researchers, UX designers and other roles more geared towards user experience or full vision,” she explained. “We aimed to get those people involved so people can learn from them.” 

More than 17 industry and academic sponsors supported this year’s event. SF Hacks 2025 was the first SF Hacks to secure a title sponsor and co-host OpenMind through the single largest contribution in SF Hacks history, the team explains. Some sponsors supported specific tracks: SFSU’s Lam Family College of Business sponsored the “best start-up pitch” track, rewarding the top team a $1,000 seed fund. In total, 32 judges awarded over $7,000 in prizes (monitors, air fryers, cash and more) across different challenge tracks and overall competition.

All of this — event logistics, finances, marketing, sponsorship and all other details — was organized by students. The core SF Hacks leadership includes over 40 students who collaborate with another 11 SFSU student organizations. 

“I’ve been here for two years. I was roped into it by my friend. Now I’m too deep into it and can’t quit,” laughed Thakker, a third-year Computer Science major. 

 “When you plan it, it’s very satisfying to see everything that you worked for and seeing the impact,” added SF Hacks Treasurer Kurt Balais, a Computer Science senior.

The grants expand research opportunities in engineering, robotics and quantum computing

Technology is constantly evolving, which means industries — and the people who work for them — must change to keep up. San Francisco State University faculty want to make sure their students have the skills and flexibility they need to compete in these growing, ever-shifting fields such as civil, mechanical and computer engineering and quantum computing.

Three new grants — two from the Department of Defense (DOD) and one from the Department of Energy (DOE) — will expand the research capabilities of San Francisco State students and better prepare them to achieve their academic and career goals. The faculty leading these projects are in SF State’s School of Engineering (SOE) and Department of Computer Science. 

Structural hazard mitigation research

A $541,541 DOD grant was awarded to SOE Professor Zhaoshuo Jiang, who leads the Intelligent Structural Hazard Mitigation lab. The funds support purchasing two state-of-the-art shake tables (Quanser Corporation’s six-degrees of freedom hexapod motion platforms) and a high-throughput data acquisition system (DAQ). This new equipment will significantly advance the capacity of performing experimental testing with accurate sensing and control, thereby enhancing the institution’s ability to support diverse research areas that are of interest to DOD. The new tables can hold a load of up to 100 kg per platform and shake objects in all three axes, a significant step up from the currently available tables, which only move along a single direction and can accommodate a maximum of 7.5 kg. This means researchers can assess larger prototypes under more realistic conditions. The DAQ system from Crystal Instruments is a high-performance, modular platform designed for real-time dynamic signal analysis, offering flexibility in channel configurations and real-time processing capabilities. The DAQ system will be integrated with the shake tables to assemble a complete instrumentation that supports a wide range of state-of-the-art research and offer unprecedented research capacity in SOE at SF State.

“This new equipment will allow students to gain hands-on experience with common research purpose of characterizing, modeling, and testing various systems,” Jiang said. “By working directly with state-of-the-art technology, our students will develop skills that make them highly competitive and well-prepared for careers in these fields.”

The new instrumentation will be housed in the applied project space in the University’s new Science & Engineering Innovation Center (SEC). Jiang’s collaborators include SOE Professors Cheng Chen and Xiaorong Zhang, Associate Professor David Quintero and Jenna Wong, and Assistant Professor Zhuwei Qin.

Human-machine performance lab

DOD awarded another $409,433 grant to School of Engineering Associate Professor David Quintero to acquire state-of-the-art instrumentation for a human-machine performance lab. The new equipment will include a treadmill, markerless motion capture and human-machine interaction equipment like a robotic leg, hip exoskeleton and rehabilitation robot. Combining these instruments will help establish a research system that integrates humans and machines to enhance human physical and cognitive performance. 

Quintero leads SF State’s CARE (Controls for Assistive and Rehabilitation Robotics) lab, which focuses on designing wearable robotic systems that can be viable solutions for movement assistance for people with limited mobility, such as amputees or people with impaired limbs from neuromotor control deficiency. Current projects include an exoskeleton glove to help individuals with limited mobility. For this new interdisciplinary lab space, Quintero is collaborating with School of Engineering Professors Xiaorong Zhang and Zhaoshuo Jiang and Assistant Professors Sanchita Ghose and Alyssa Kubota, and Department of Kinesiology faculty Professor Kate Hamel and Associate Professor Leia Bagesteiro.

“This equipment is an important accomplishment for having SF State students access to get hands-on research practice using such equipment that will allow our students to be competitive in the job market and/or pursue Ph.D. programs,” Quintero explained. “The robotic leg alone has only be at R1 institutions and the company has stated we are the first West Coast region to acquire the robotic leg.”

Quantum computing comes to SFSU

SF State, along with Lawerence Berkeley Laboratory and Argonne National Laboratory, is part of new multi-institutional project funded by the DOE. Associate Professor of Computer Science Wes Bethel and Assistant Professor Daniel Huang were awarded $250,000 as part of the larger five-year grant aiming to bridge the gap between theoretical quantum advantages and practical scientific applications. 

Researchers will develop quantum algorithms and quantum machine learning methods applicable across diverse scientific domains. Quantum algorithms might help overcome limitations of classical data encoding such as its high computational expense of time and memory. Unfortunately, these quantum approaches have not yet improved speed. The scientists will therefore focus on efficient quantum data encoding and error mitigation. Their project will study the relationship between scientific data analysis algorithms, data types, quantum data encoding and current quantum hardware. In addition to introducing new research prospects at SF State, this project provides students new opportunities to collaborate with prestigious national labs. 

“The grant also results in new opportunities for SFSU students in the form of education and research,” Bethel said. “The SFSU Computer Science Department offers a new course in quantum computing, and the grant provides support for a limited number of students to work as part of the multi-institutional team.”

SF Hacks was a nonstop weekend filled with ‘hacking,’ friendly competition, networking, karaoke and Bob Ross

What is a hackathon? The word might conjure an image of people with their heads down furiously clacking away at a computer in silence. But that is not what happened at this year’s student-run SF Hacks event — especially now that the annual hackathon is back in person.

After being virtual for the past few years, SF Hacks returned to San Francisco State University’s Annex 1 April 5 – 7 for the first time since 2019. There were more than 200 participants, with students coming from 33 different schools and six states.

During hackathons — sometimes also called codefests — participants design projects to solve various problems. The hard part: They only have 72 hours to work on the project, write the code and troubleshoot before presenting to judges. But the competition is just one part of SF Hacks.

“Most of the time you’re staying up because you have to get homework done. But this time we’re staying up [because this hackathon] is like a huge sleepover,” said SF Hacks Co-President Arianna Yuan, a Computer Science senior.

The multi-day event is really a community celebration packed with networking, games and activities like karaoke, a Bob Ross painting workshop and a K-Pop club event. Beginners are more than welcome.

“With online hackathons, there’s a lot less room for randomly meeting a teammate and going out to do painting. [You can’t] see a bug on someone’s screen and then run across the room to communicate that to someone else,” said SF Hacks Co-President Odera Nwosu, explaining the spirit that was lost on Zoom.

This year’s challenge theme was city life. Nwosu, a Computer Science sophomore, points out it’s a very San Francisco-driven theme. Projects could address transportation, food, housing and other topics affecting students. There were also several tracks like artificial intelligence and sustainability that were set by SF Hacks and various sponsors.

“Our tracks are essentially specializations that participants can choose to try to refine and push their projects,” said SF Hacks Vice President Marco Garcia, a Computer Science sophomore. While participants might get points or prizes for following the theme or tracks, it’s not essential. The organizers knew participants have a wide array of potential projects.

Some of the project submissions that caused a stir tackled city litter and emergency response. Clean ASF gamified the act of picking up litter — a task that can often feel futile in a city like San Francisco — to encourage more folks to engage. Taking a different approach, CleanMars used a 3D-printed robot that could discover, collect and classify trash. Another popular project was SOS Hub, an AI-powered emergency response platform that can analyzed user-submitted photographs of a scene to identify and recommend the appropriate first responders. Some of the winning projects — spread across different categories — are publicly shared in a Devpost gallery.

The student organizers recruited more than 30 sponsors ranging from SF State’s colleges, departments and student organizations to industry giants like OpenAI, CISCO and Kaiser Permanente. Many sponsors participated in the live event.

“Hackers will make some awesome, insightful and creative projects. It’s a great way for [students] to show off what they can do to people who might be noticing,” said SF Hacks Marketing Director Ria Thakker, Computer Science sophomore.

The event was organized by over 20 SF State students. Nwosu says they received a lot of support from alumni, emphasizing that community is at the core of SF Hacks. While some of this year’s student organizers have attended hackathons, many were new to hackathons or it was their first time with SF Hacks.

“I’ve met incredible people and I love the team,” said Yuan, one of the few long-term SF Hack organizers. She originally joined after participating in hackathons in high school. Now she’s about to graduate college and gets sentimental thinking about leaving SF Hacks. “It is kind of sad to see this little baby go, but I trust that it’s in good hands. It’s just very lovely to have an incredible team that you can work with and trust and get stuff done. It’s just a gigantic project.”

The Ethical AI certificate provides a foundation in the computer science, philosophy and business of ethical AI

U.S. President Joe Biden recently issued an executive order on managing the risks of artificial intelligence (AI), and the European Union is discussing AI laws abroad. While the news has been flooded with stories of self-driving cars, Chat GPT and how AI will affect jobs, a group of San Francisco State University faculty has been concerned by the ethical implications of AI for years.

That’s why they developed San Francisco State’s Graduate Certificate in Ethical Artificial Intelligence in 2019. The program was created by Computer Science Professor Dragutin Petkovic, Lam Family College of Business Professor Denise Kleinrichert, and Philosophy Professor Carlos Montemayor. They’ve seen the impact of this program on students and think this type of education is as important as ever. Any SF State graduate student and anyone with a bachelor’s degree (non-matriculated post-baccalaureates) can apply for the program.

“People don’t understand the issues of AI and its impact to society. It can create problems because now it’s everywhere,” Petkovic explained, noting that the potential problems are not just limited to a single industry. “In my opinion, [ethical AI education is the] most consequential project I’ve been working on by far.”

AI technologies continue to grow and impact everything from health care, defense, media, education and more. Despite advances, AI systems can still produce errors, demonstrate biases and lack transparency in decision making. The faculty knew that everyone — AI users, educators, politicians, lawyers, auditors and others — would need access to ethical AI education to make informed decisions.

“The professors are not talking to you as though you’re already an expert in the subdomains,” said Rafael Ayala (M.A., ’22), who works at the software corporation Autodesk in third-party risk management. “They are making sure we have access to broad scopes of knowledge and bringing people together.”

Ayala came to SF State with a background in philosophy and education. As a first-generation student and the first in his family to go to college, it wasn’t easy for him to tell his family he was leaving his paid job to pursue a master’s degree in Philosophy. Though he partly chose SF State because of the Ethical AI program — he could see its growing prominence in everyday life — he had no aspirations for a career in tech.

“The program did a great job of helping me build up that technical prowess and having the vocabulary I needed,” he explained, crediting the certificate for building his confidence to work at Autodesk. “I am working in tech, and … artificial intelligence is huge and we need to constantly evaluate [it].”

As part of Adobe’s legal team, attorney Ted McCullough became more interested in AI two years ago. He enrolled in the certificate program because he wanted to know about the ethical dimensions of the technology, but also had technical computer science questions. He was recently promoted to a director role on the legal team at Adobe, in part due to the AI expertise he gained from the certificate program.

“[SF State’s program] seemed like a really good fit because it had everything that I was looking for in terms of a computer science curriculum, a philosophy curriculum and a business curriculum all with a practical bent,” he said.

Coming in with an academic background in computer science and philosophy, McCullough feels there’s often a curriculum gap between the math and science of AI and the policy issues, but that this certificate helps begin filling that gap.

The certificate was designed to be accessible for any non-expert, Petkovic said. He hopes more students, working professionals, and employers take advantage of the University program. Though the certificate requires a bachelor’s degree for enrollment, he encourages undergraduates and anyone else interested to reach out to the him and his faculty colleagues about possible options.

“We need to educate people, but then there has to be some level of regulation … ,” Petkovic said, emphasizing why everyone from computer scientists to government officials should receive a holistic education on AI. “We are one part of the puzzle.”

Collaborating with other CSUs, the University will help bring more high school computer science education to Northern California

In 2016, President Barack Obama made a national call for more hands-on computer science and math classes to prepare all students for the evolving workforce. San Francisco State University Computer Science faculty took the call to heart and started the University’s Computer Science for All (CSforAll) program in partnership with the San Francisco Unified School District (SFUSD). A new $2-million grant from the National Science Foundation will expand the successful program to other California State University (CSU) campuses to bring computer science to more Northern California high schools (CS4NorthCal).

San Francisco State plans to establish a consortium with San Jose State University, Sonoma State University and Sacramento State University. The four CSUs will join forces with WestEd and more than 20 school districts with a goal of preparing and supporting 200 teachers and more than 25,000 high school students.

“Females and people from traditionally underrepresented groups are not well represented in the computing industry. The same pattern actually plays out in high school classrooms,” said Director of SF State’s CSforAll Hao Yue, a professor and associate chair of Computer Science. He explained that part of the issue is the lack of teachers who are specifically trained to provide rigorous computer science instruction and create an inclusive learning environment that can engage all students, particularly female students and students from underrepresented groups.

As part of the original CSforAll initiative, SF State was the first CSU to offer a computer science supplementary authorization. This allowed K – 12 SFUSD teachers to take a handful of classes and earn computer science teaching credentials. Many local participants were from high-need schools and were the first authorized computer science teachers at their schools, Yue said. Since 2018, the program has trained more than 100 K – 12 teachers, 61% female and 36% from underrepresented groups.

“The best way we can support teachers in a lot of areas in Northern California — from urban, suburban and even rural areas — is by supporting the CSU campuses to replicate and scale our successful program to their regions,” Yue said.

Roy King, a teacher at Raoul Wallenberg High School in San Francisco, participated in CSforAll a few years ago. He’s been a teacher for more than 20 years and has been at this school for five. CSforAll helped him shift from teaching math to computer science.

“Demystifying the code behind what the students are doing, like the technologies in their everyday life, and just to be able to open it up — I think that can give kids a lot of confidence,” he said. He’s also noticed that computer science is helping students get more interested in math.

“As a Black man, I’m trying to get as many underrepresented people into the tech world as possible. So women, our special education students, people of color … ,” he said. “I think [CSforAll] was just fantastic. I recommend it to everybody. It would have taken me on my own five times as long to learn all the material I learned in the program.”

Over the years, King has started to see a shift, with more girls starting to take high school’s computer science classes. More girls and students of color are sharing with him that they can see themselves in this space as a career.

In addition to the supplementary authorization, SF State’s CSforAll provides teachers with a professional teaching community. The program also trains SF State Computer Science undergraduates to be in-class teaching assistants. Working with University students, King gleaned a lot of insight about the tech industry and college that he could relay back to his students. 

Kami Sawekchim (B.S., ’22), a former CSforAll teaching assistant, taught at a high school in the Potrero district in a class that combined computer science and art. The school had a high population of students with learning disabilities.

“I think I was able to help give some inspiration into [why] computer science may be a really good career choice. A lot of these kids come from disadvantaged backgrounds. Coming from a similar background, I really related to them,” she said. She recalls that students were very curious about the job market, salaries, college applications, an internship she had at Genentech and more.

“I would say that I maybe don’t fit into the standard perspective of what a computer scientist is,” she said. “But that’s the point of why I chose computer science. I want to change the image of what people think [computer science] is.” Thanks to CSforAll, Sawekchim managed to land a full-time Genentech job and has already volunteered to tutor a local high school student.

Yue hopes that the new CS4NorthCal will continue this trend of expanding inclusive computer science learning environments. Addressing the lack of qualified teachers, he hopes the effects will trickle down to fixing the workforce pipeline problem by getting more underrepresented populations and women into the workforce.
