I am a dual major in Theoretical Mathematics and Computer Science (AI Specialization) at the Ohio State University. I am interested in complexity theory, graph theory, and machine learning.


Experience

Software Engineering Intern

Google

Modernize and add features to an open source Javascript library that allows sharing of information among third party libraries. Migrate tests to jasmine/karma, setup build system with yarn using grunt using Closure, add a feature, and review peer PRs on github.

Build an open source JavaScript library for data collection. Sites write simple code to say which events they want, the library sends data about events to libraries of choice (e.g. Google Analytics) and stores data automatically with software of choice (e.g. cookies). Made SPA test site with react, html/css, redux.

Summer 2020

Research in Machine Learning

Under Mikhail Belkin

Implement a kernel-based machine learning algorithm "Eigenpro" that improves the convergence speed of SGD by reducing spectral decay using python/numpy. Publish algorithm in the sklearn-extra machine learning library. Create documentation website.

Summer 2018 - Present

Research in Topology

Under Facundo Memoli

Prove results relating to the Gromov-Hausdorff metric for distances between metric spaces, particularly the unit circle/sphere with geodesic distance. Computationally generate lower bounds on these distances using integer linear programming as well as a combination of a pruning algorithm and parallel processing with AWS.

Summer 2019

Data Quality Intern

FCX Performance

Clean address data with Excel, design algorithm to reduce the amount of manual work. Give recommendations for improving data quality short-term and long-term by considering patterns in the data. Utilize WTTE-RNN model to predict churn of customers given their buying history.

Summer 2019

Software 1 Intro to Java TA/Grader

Ohio State University

Work 7 hr/week for a semester assisting in lab, holding office hours. Grade projects and HW.
