I am a PhD student in the department of computer science at the University of Illinois at Urbana-Champaign within the Programming Languages, Formal Methods, and Software Engineering (PL-FM-SE) area. I am co-advised by professor Tao Xie and professor Madhusudan Parthasarathy. My research interests are in software testing, program synthesis and machine learning. My current research focuses on building robust testing-based learning frameworks for synthesizing specifications.
I obtained a Bachelor of Science (B.S.) in Computer Science and Engineering with Magna Cum Laude Honors from The Ohio State University. During my time as an undergraduate, I participated in the Summer Research Opportunities Program (SROP) where I engaged in rigourous research experiences. This includes a stint at Purdue University with Professor Xiangyu Zhang and at the University of Iowa with Professor Aaron Stump.
