I am a WiSE Gabilan Assistant Professor of Computer Science at the University of Southern California. I am broadly interested in software engineering, software security, and computer systems. My work aims to build testing and analysis techniques for improving the reliability, security, and efficiency of complex software systems. My research has been recognized with several awards, including N2Women Rising Stars in Networking and Communications (2024), University at Buffalo Exceptional Scholar - Young Investigator Award (2022), NSF CAREER Award (2021), Facebook Testing and Verification Research Award (2019), Mozilla Research Award (2019), and Maurice H. Halstead Memorial Research Award (2018). I received my Ph.D. degree in Computer Science from Purdue University in 2018.
