About

I’m an M.S. Machine Learning student at Carnegie Mellon University and a graduate student researcher in the Human Sensing Laboratory. My current research explores how large language models internally represent positions on social and political issues.

Previously, I built basketball video analysis systems at Paloa, worked on software and infrastructure at Cvent, and co-founded SiliconMCP, formerly LoopCell, to support AI driven chip design. I graduated from UT Austin with an Honors degree in Computer Science, summa cum laude.

Outside of work, I enjoy public speaking, nonprofit fundraising, sports, reading, cooking, and traveling. My past modeling and acting work included representation by Entourage Model and Talent Agency (opens in a new tab).

Research

Current questions and earlier investigations.

Measuring Values in Large Language Models

Graduate Student Researcher
Human Sensing Laboratory, Carnegie Mellon University

Developing a metric to audit how large language models internally represent positions on value-laden social and political issues. I evaluate consistency across prompts and contexts using open-source models, informed by interpretability and value-measurement research.

RAG Retrieval Benchmarking & NER Model Evaluation

Independent Research with Dr. Anshumali Shrivastava
ThirdAI

Designed retrieval benchmarks covering single-document retrieval and multi-document questions with single or multiple answers. I curated datasets, measured retrieval quality and latency, and evaluated eight transformer NER models on precision, recall, F1, and CPU inference latency under 10 milliseconds. I also tested self-hosted vision-language models for document processing and wrote reports informing architecture decisions.

Network Optimization for 5G & Starlink Deployments

Independent Research with Prof. Chandrajit Bajaj
The University of Texas at Austin

Compared genetic algorithms, deep reinforcement learning, and graph neural networks for dynamic network optimization. I documented data flow, equations, and optimization trade-offs, and proposed a hybrid reinforcement learning and GNN framework for scalable deployments.

Earlier research

Medical Device Network Discovery

Research Fellow
The University of Texas at Austin

Designed a Raspberry Pi scanner and Python tools to discover medical devices on a healthcare network, classify vendors, and generate a security inventory with IP addresses, MAC addresses, and device details. I also explored network fingerprinting to improve detection accuracy.

Mosquito Identification from Audio Signatures

Student Researcher with Dr. Timothy Riedel
DIY Diagnostics Lab, The University of Texas at Austin

Built an Arduino recording device to capture mosquito wing beat audio, then used noise removal and frequency analysis to study species-specific acoustic signatures.
