Hi, I'm Mark
I'm a Ph.D. in Physics interested in Artificial Intelligence, building communities, compassionate leadership, and public policy. As Director of AI/ML Engineering at Dexcom, I lead the team responsible for all consumer-facing AI/ML surfaces, from research and design through production and monitoring. I spend a lot of time thinking about how Large Language Models and generative AI systems are impacting the way humans work and live, and my primary research interests include AI alignment and evaluation, large metabolic models for biosensing, and the integration of wearable data with AI systems.
I received my Ph.D. in physics at University of California, San Diego, where my dissertation research in experimental particle physics focused on new physics searches at the Large Hadron Collider, and received my undergraduate B.A. in Physics and Mathematics from University of California, Berkeley, where I worked on machine-learning optimization of physics searches at Lawrence Berkeley National Laboratory.
I'm also a big believer in staying socially engaged and politically active. In the past I have advocated on behalf of fellow graduate students, argued for increased investments in higher education and research, and implemented programs for historically underserved communities. I continue to stay close to local, state, and national advocacy initiatives through alumni groups and conversations with fellow policy junkies, and am always eager to chat about how we can work together to drive meaningful, equitable reform.
