Physics-Informed Neural Networks (PINNs)
Tests whether building physics into a neural network helps predict how long 3D-printed metal parts last before cracking. Across 8 datasets (30 to 10,000+ samples), it did not consistently beat standard models. Data quality mattered more.
Abstract submitted to Fatigue Design 2027.
Tools: Python, PyTorch, scikit-learn, Monte Carlo simulation, AI, machine learning
NLP & LSTM Language Model
Analyzes the words and emotional tone of 250+ songs, then trains an AI to write new lyrics in a similar style by predicting the next word.
Tools: Python, NLTK, LSTM neural network, Tableau, AI, machine learning
Predictive Modeling of California’s Energy Systems
Forecasts California’s energy production and consumption from 20 years of state data. I compared 7 models, and the best one matched the data almost exactly, with an RMSE of 4.9e-10.
Tools: Python, Google Colab, Tableau, regression, machine learning
Student Rental: Use Case Study Report
Designs a database for a student housing rental service to keep information organized and easy to search. Built and tested in MySQL, MongoDB, and Python.
Tools: MySQL, MongoDB, Python
Photovoltaics: The Science, History, and Future
Explains how solar panels work and weighs the strengths and limits of solar energy, from the physics to the economics. I presented it to 40 students as a guest lecturer.
Tools: research, circuit diagrams, presentations
Startup Data Dashboard
Shows which industries attract the highest valuations among 1,000 startups valued at $1B or more. Fintech came out on top.
Tools: Tableau
