Research Projects

Ongoing Project Summer 2025 - Spring 2026

Floating Point & Deep Network Project

Teerat Chanromyen

Advisors: Prof. Eliot Moss, Prof. Philip Thomas

We investigate how errors from floating-point arithmetic, and how more accurate methods such as compensated summation, affect the training of deep neural networks.

Completed Project Fall 2025

Manipulation and Optimization of LLMs in RAG Systems

Teerat Chanromyen

Advisor: Prof. James Allan

This Search Engine Honors project explores how different manipulation techniques influence the downstream product recommendation behavior of retrieval-augmented generation (RAG) systems. We also experiment with various defense mechanisms to mitigate such manipulations.

Completed Project Summer 2025

Robust and Privacy-Aware De-Identification of Clinical Text Using Modular NLP Pipelines

Teerat Chanromyen, Jimmy Jiang, LiYu Zeng

Advisor: Rohan Pandey

We implemented an NLP pipeline for medical text de-identification with several surrogacy techniques on the i2b2 dataset, and evaluated them using privacy metrics, downstream task performance, and adversarial GPT-5 benchmarking.

Completed Project Fall 2024 - Spring 2025

Fast Python Tree Decomposition Algorithm

Teerat Chanromyen

Advisors: Prof. Hung Le, An La

We researched heuristics and implemented a fast tree decomposition algorithm in Python, achieving significant speedups over NetworkX library on benchmark road network datasets.
