Hi! I'm a fourth-year PhD student in the Computer Science department at Drexel University and a member of Drexel EconCS research group. My advisor is Vasilis Gkatzelis. I am interested in the intersection of Economics and Computer Science, particularly
in algorithmic game theory, mechanism design and fair division. I was a Research Intern at Google Mountain View during summer 2023.
I received my bachelor's degree from Drexel University, majoring in Mathematics. During my undergraduate years, I have worked as assistant product
manager in Comcast and Digital Quality Operations Analyst in JPMorgan Chase & Co.
