About Me

I recently completed my PhD at Stanford and am now co-founding a startup, DBOS, Inc.! In graduate school, I studied computer science (particularly databases and systems research) and was advised by Matei Zaharia and Peter Bailis. A big part of my PhD was spent on the DBMS-oriented Operating System (DBOS) project (CIDR 2022, VLDB 2022), particularly Epoxy (VLDB 2023) and Apiary (arXiv). Other projects I have worked on include Data-Parallel Actors (NSDI 2022), POP (SOSP 2021), Willump (MLSys 2020, VLDB 2020), MacroBase (Best of VLDB 2019) and Arachne (OSDI 2018). I did my undergrad at Harvard, where I worked with Margo Seltzer on my senior thesis and Alexander Rush on predicting congressional voting records from bill text (EMNLP 2016).
