I am currently a 3rd year PhD student in Computer Science (CS) at Stanford University, advised by Prof. Jure Leskovec and Prof. Johan Ugander.
Previously, I completed my undergrad at Columbia University, where I majored in CS and concentrated in Sociology, and was advised by Prof. Kathy McKeown.
My research is supported by the NSF Graduate Research Fellowship.
I'm interested in developing computational methods to model complex, interconnected systems in social and population health domains. Recent work includes modeling the dynamics of COVID-19 transmission, predicting human mobility patterns, and analyzing the societal impacts of recommendation systems.
Key areas: networks, data science, machine learning, computational social science

Built a user-facing feature for Google Search and Assistant. Designed new logic to recognize and parse natural language queries related to the feature, implemented backend in Search architecture, and worked with UX designer and Product Manager to create frontend for the feature.
Modified Google Search architecture to add new tracking metrics and used these metrics to improve the primary monitoring console for Google Now. Also completed two stretch projects that improved the functionality of company-wide monitoring tools.
Lean In at Columbia
Co-President (2017-2018); Senior Advisor (2018-2019)
As Co-President, I revamped our program to focus on our members' professional and personal growth in the context of intersectional experiences, such as being LGBTQ or interdisciplinary. With my Co-President Kara Schechtman and our Board, we quintupled the size of our membership and founded a mentorship program, which matched over 70 students to NYC professionals in its first year. We also founded the Lean In @ CU Conference, a day-long event celebrating mentorship and different paths of feminism.
Columbia Womxn in CS (WiCS)
Academic Chair (2017-2019)
I founded WiCS Lightning Talks, a new speaker series at Columbia featuring student researchers with a focus on supporting traditionally underrepresented groups in CS. The series empowers student researchers by giving them the opportunity to present their work, and, in turn, inspires their peers to dive into research. As Academic Chair, I also organized panels with CS faculty at Columbia, and participated as a mentor in WiCS' Coffee Chats program.
Intercollegiate Chamber Music Festival (ICMF)
Co-Founder; Producer (2017-2019)
I co-founded this initiative while serving as Co-President of Columbia Classical Performers. Along with my Co-President Cindy Liu and Vice President Dean Deng, we founded ICMF in collaboration with The Chamber Music Society of Lincoln Center. The festival celebrates collegiate chamber ensembles, providing them opportunities to perform at Lincoln Center and to particpate in master classes with world-renowned artists.
