Research Projects
Knowledge Distillation for Transformer Based NLP Models (2021 - 2022)
This is a project I am working on under the guidance of Dr. Colin Raffel in his research group at UNC.
Project description: I am working on a deep learning knowledge distillation (KD) project which aims to establish a consistent methodology to map large pre-trained neural network models to smaller, more practical, models while preserving model accuracy both before and after fine tuning for downstream tasks. This project builds upon prior model distillation work but considers using pre-trained student models for KD and hopes to compile the "best practices" for KD. We are largely considering models like BERT (any many others related to or stemming from BERT).

Deep Learning Pose Prediction on Drone Imaging of Whales (2021)
This is a semester-long project I am working on under the guidance of Dr. David Johnston at the Marine Robotics and Remote Sensing Lab (MaRRS) which is housed at the Duke Marine Lab (DUML) facility on Pivers Island, Morehead City, NC.
Project description: I am creating and training a deep learning framework for the task of pose prediction on drone videos of whales taken around the globe. We are currently looking at Minke whales, Blue whales, and Humpback whales. The goal of this project is to provide behavioral scientists with a quantifiable mechanism to track and predict an animal's movements.

FLOPs Aware Deep Learning (2021)
This is a project I worked on through the Department of Energy Summer Undergraduate Learning Internship Program. I worked with the Leadership Computing Facility's (ALCF) Data Science team at Argonne National Laboratories (ANL) with Dr. Kyle Felker and Dr. Taylor Childers.

Computer Organization Teaching Assistant (2021 Spring and Summer)
I served as a Teaching Assistant for Computer Organization (COMP 311) under Dr. Henry Fuchs at UNC Chapel Hill. While this is not a research project, this TAing experience got me really interested in computer architecture, and it is a field I would love to study further/conduct research in some day.
Responsibilities: Create and grade homeworks, labs, quizzes, and tests. Host office hours to assist students with conceptual and assignment related questions.
FlyBy CNN (2020-2021)
I have been working on this project under the guidance of Dr. Juan Prieto and Dr. Martin Styner at the UNC Neuro Image Research Analysis Laboratories (NIRAL).
"Fly by CNN is an approach to capture 2D views from 3D objects and use the generated images to train deep learning algorithms or make inference once you have a trained model."
Project description: I am working to establish Fly by CNN's role as useful pre-processing tool to generate image sequences of brain MRIs for deep learning purposes. This is an important project because current state-of-the-art deep learning techniques focusing on neuro-imaging are extremely slow an inefficient due to the size of raw MRIs (or other traditional imaging). My project has preliminarily shown that with as little as 16 zoomed-in views of a brain, the age of the patient can be discerned with attention-based neural networks. FlyBy is capable of projecting properties of an image onto the surface of a 3D model before producing an image sequence. This is fascinating because in some cases deep learners using Fly By images are able to perform classification with fewer neuro-morphic features (such as sulcal depth, cortical thickness, and surface area) than was originally hypothesized. Even more interestingly, FlyBy is even able to accurately perform with extremely zoomed in image sequence which do not show the entire brain. Overall, this is an extremely exciting study which is providing a lot of insight into deep learning for the brain surface.

Detection of Atypical Neurodevelopment in Infants Using PCA and KMeans Clustering (2020)
This was a final research project that I completed for my Introduction to Machine Learning Class (COMP 562) at UNC, Chapel Hill. The code we used to uncover these results is available in the GitHub repository below, however, due to HIPPA regulations, the data is not provided. Citations are listed at the bottom of the paper.

Global Extra-Axial Cerebrospinal Fluid Investigation (2019 - ongoing)
I have been studying the global extra-axial cerebrospinal fluid space in infants under the guidance of Dr. Martin Styner at the UNC Neuro Image Research Analysis Laboratories (NIRAL).
Project description: Currently my project has branched into two main focuses:
My first study has established a physiological difference in EA-CSF volumes in twins versus non-twin individuals.
My second study is currently establishing the significant adverse role of elevated EA-CSF at infancy in a child’s performance in a battery of behavioral, cognitive, and emotional tests administered at age 6.

Rubiks Cube Solver in C (2019)
Fun project to build a Rubik's cube solver from scratch - not very clean code. I came up with a "catch-all-cases" algorithm by tinkering around with a Rubik's cube, so it is definitely not very efficient. Let me know if you find a bug in the algorithm/code.
Graph Theory - Reversed Arcs Investigation (2018)
This was the final project for my high school Introduction to Proofs and Graph Theory class at the North Carolina School of Science and Mathematics where we investigated reversed arcs. See paper below for findings.
