Using Large Language Models for Targeted Phishing Attacks

Under the direction of Dr. Tom Goldstein in UMD’s machine learning capstone course, I am working on a project designed to test the effectiveness of large language models for hyper-targeted phishing...

Spiking Neural Networks for Object Detection

As a part of undergraduate research with Dr. Sahil Shah, I am developing a spiking network for object detection. Currently, I am building and comparing several networks for object detection includ...

Automated Large Language Model Evaluation & APLCOLLAB

While at JHU APL, I developed a communication script between GPT 3.5 Turbo and Dolly 12B or Stable Vicuna 13B allowing them to engage in a directed dialog designed to eliminate manual testing of la...

Shift Equivariant Vision Transformers

I supported the development of a shift equivariant Vision Transformer. By making the vision transformer shift equivariant, it would potentially better classify images that are shifted from their or...

Comparing Various Deep Learning Techniques for Image Classification

For my data science class’ final project, I chose to compare the performance of different deep learning architectures on the classic MNIST dataset. In the project, I used a convolutional neural net...

Transformer Models for Network Traffic Analysis

While at JHU APL, I created transformer-based machine learning model for anomalous network traffic detection that yielded significantly higher accuracy than previous LSTM-based models. I also depl...

Analyzing Moral Foundations From Text Using Transformer-Based Models

I analyzed moral foundations from text using a BERT model while working at the Johns Hopkins Applied Physics Laboratory. The text was categorized into the six moral foundations as described here. ...

Expanding Upon LSTM Models for Network Traffic Analysis

As a part of my second high school internship at the Johns Hopkins Applied Physics Laboratory, I expanded my previous LSTM-based anomalous network traffic model to detect additional types of traffi...

Applying LSTM Models to Network Traffic Analysis

As a part of my first high school internship at the Johns Hopkins Applied Physics Laboratory, I developed LSTM-based machine learning models for anomalous network traffic detection. I also created ...
