Hi, I'm Mark

I'm a Ph.D. in Physics with a passion for Artificial Intelligence, building communities, compassionate leadership, and public policy. Currently I work as a Data Scientist at Dexcom, where I am leading our AI Experience team in Large Language Model feature design, risk assessment, and development.

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.

Where I've Been

Some endeavors, past and present

Dexcom

Sr. Manager, AI Experience, Since Sept. 2023
Sr. Manager, Experience Individualization, Dec. 2020 - Aug. 2023
Staff Data Scientist, May 2018 - Nov. 2020
San Diego, CA

Today I coordinate data science & AI initiatives at Dexcom where I lead the AI Experience team. Our team is responsible for building state-of-the-art AI and machine learning models to deliver insightful and intuitive experiences for Dexcom's customers. This includes LLM feature design and risk assessment to develop the next-generation algorithms empowering users to take control of their health. At Dexcom I've found a home of talented scientists, engineers, and commercial experts who work together to transform diabetes management. Our team tackles complex problems in medical and commercial applications, while pushing the boundaries of our organization's immense data capabilities.

European Organization for Nuclear Research (CERN)

Doctoral Student Researcher, 2014 - 2018
Geneva, Switzerland

My dissertation research in experimental particle physics focused on new physics searches with the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) at CERN, where I was advised by Professors Frank Wuerthwein and Avi Yagil. As a graduate student I developed new techniques and variables for physics analysis, developing frameworks in C++ and Python for processing petabytes of physics data. My time at CERN was one of the most intellectually stimulating experiences of my career, where I had the opportunity to work within small teams and large collaborations at the forefront of modern physics.

Graduate Student Association, UCSD

President, 2017 - 2018
VP of External Affairs, 2016 - 2017
Legislative Liaison, 2015 - 2016
San Diego, CA

It is difficult for me to imagine graduate school without all the support of the community I found in the GSA. As a member of our Lobby Corps, a Legislative Liaison, and VP External, I assisted in our legislative lobby efforts and ultimately worked to determine our advocacy priorities, representing the needs of graduate students at the state and national level. As the President of the GSA, I oversaw the operations and initiatives of organization and worked worked on behalf of the 7000 graduate students at UCSD.

Lawrence Berkeley National Laboratory

Research Assistant, 2012 - 2013
Berkeley, CA

My years in Berkeley were a transformative time where I learned much about physics, programming, machine learning, and myself. While completing my undergraduate program at UC Berkeley, I had my first encounter with particle physics. Under the advisement of Professor Yury Kolomensky, I worked with the BaBar collaboration at LBNL on searches for new physics in invisible decays of a dark photons, research which ultimately inspired me to pursue my graduate degree.
