I study computer science at The George Washington University. I completed a BS in '22 and expect to complete an MS in '23. I am applying for PhD programs in computer science for Fall 2023.

Here is my CV and my GitHub. Here is information about my teaching and tutoring.

Research

My research interests are still forming, but I like thinking mathematically, and I've particularly enjoyed working on projects that have social impact.

Statistical Election Audits

Since 2020 I've been a member of Professor Poorvi Vora's research group on risk-limiting audits (RLAs), rigorous statistical procedures used to detect errors in election results. We developed PROVIDENCE, the most efficient and secure ballot polling RLA known today. I wrote the proof that PROVIDENCE is risk-limiting, designed and conducted simulation experiments, implemented it in open source RLA software, and participated in its pilot use by the US State of Rhode Island, described in their press release. I presented a poster at the 2022 GW SEAS R+D Showcase. Preprints and publications are given below, and an additional manuscript is in preparation.

Glitter

Hold a sheet of a glitter to light and enjoy the sparkles. Move it just slightly, and a whole new sparkle pattern emerges! This high sensitivity of appearance to pose gives glitter sheets strong potential as a cheap target for single image camera calibration. Since Summer 2022, I've been working with Professor Robert Pless and peer Addy Irankunda on this problem. I've made a few blogs posts about it: 1, 2, 3, 4, 5.

A sheet of a glitter with fiducial markers in the corner for locating individual specs; this is a real prototype of the camera calibration target we are proposing.

Scheduling

I designed and analyzed scheduling algorithms using the imprecise computation model for a project on real-time AI at the edge. Here is the software, and our submission is given below.
