LLM Evaluation Framework Comparison

Comparative Study of LLM Evaluation Frameworks (Deloitte-Anthropic Alliance)

In collaboration with Deloitte’s Anthropic Alliance, this capstone research for the M.S. in Data Science at the University of Virginia critically examines leading frameworks for evaluating large language models (LLMs). The study leverages multiple datasets and methodologies to benchmark state-of-the-art approaches for ethical and reliable AI assessment. This comprehensive research evaluated and compared multiple LLM evaluation frameworks across eight critical metrics: toxicity detection, bias detection, hallucination detection, summarization quality, tone identification, readability assessment, retrieval accuracy, and response accuracy.

GPU Matrix Operations Performance Benchmarking

Benchmarking GPU Matrix Operations Optimizations

Completed project for CS6501: GPU Architectures at the University of Virginia. This research presents a comprehensive benchmarking study of matrix operation optimizations across NVIDIA GPU architectures, focusing on matrix transpose and multiplication. Through systematic evaluation of custom CUDA kernels and library implementations across RTX 2080 Ti and A100 GPUs, demonstrated that vectorized implementations achieve up to 6x speedup over naive approaches, reaching 1800 GB/s throughput on A100.

AI-Generated Text Detection

Detecting AI-Generated Text: Targeting Academic Integrity Applications

Completed for DS6051: Decoding Large Language Models at UVA, this project explores transformer-based methods for detecting AI-generated text in academic contexts. By fine-tuning RoBERTa using LoRA and optimizing for human accuracy, the model reduced false positives on human-written abstracts from 83.2% to just 0.7%, demonstrating the importance of fairness and robustness in detection systems.

Speech Emotion Recognition

As part of my Deep Learning course, this project explores the use of convolutional and recurrent neural networks for Speech Emotion Recognition (SER). Using the RAVDESS and TESS datasets, we train models to classify emotions from audio signals, aiming to improve human-computer interaction, mental health applications, and AI-driven affective computing.
