## Xizhi Tan

Xizhi Tan, currently a PhD candidate at Drexel University under the guidance of Vasilis Gkatzelis, holds a Bachelor's degree in Mathematics from the same institution. Her research is centered around the integration of mechanism design and machine learning. Her thesis focuses on "learning-augmented mechanisms," exploring how predictions can be used to enhance mechanisms in strategic settings while maintaining worst-case guarantees.

## Marius Garbea

Marius Garbea is a PhD student at Drexel. He previously graduated from Drexel in 2021, with a double major in Computer Science and Mathematics. He is from Romania and came to Drexel after focusing on computer science in general and data structures and algorithms in particular during high school. He is interested in algorithms that span the blockchain space, such as decentralization, cryptography, consensus in networks, and game theory. He has been a member of the reading group since the fall of 2018.

## Rishi Patel

Rishi Patel is a PhD student at Drexel. He previously graduated from Drexel in 2021, with a double major in Computer Science and Mathematics. His interests include the applications of mathematics to computer science. He has previously researched type systems and he spent two terms as a research co-op conducting research in the design and analysis of ascending auctions. He has also previously worked as a software engineer for Lockheed Martin. He has been a member of the reading group since the fall of 2018.

# Alumni

Dan Schoepflin graduated with a PhD from Drexel University in the summer of 2023 (advised by Vasilis Gkatzelis). He subsequently joined Simons Laufer Mathematical Sciences Institute at Berkeley as a postdoctoral scholar. His main research interests are algorithmic mechanism design and approximation algorithms with a particular focus on designing and analyzing practical mechanisms. In Summer 2022, he was a research intern at Google under the supervision of Gagan Goel.

## Nick DeFilippis

Nick DeFilippis graduated from Drexel in 2022 with a double major in Mathematics and Computer Science and a minor in Astrophysics. He then joined the mathematics PhD program of the Courant Institute of NYU. His interests are in using mathematics and computer science to develop solutions to real-world problems.

## Pranav Garimidi

Pranav Garimidi is a junior at Columbia University, pursuing a degree in Computer Science. He joined the reading group as a junior in high school, conducting research on the fair allocation of indivisible goods under the supervision of Vasilis Gkatzelis, which led to a AAAI publication while he was still in high school. He subsequently published more work on fair division and auctions.
