About Me

I am a Statistical Sciences PhD candidate based in Houston, currently completing my degree under the supervision of Prof. Tim Gebbie.

Research Focus: Spectral Representation Learning

My PhD projects focus on Spectral Representation Learning, specifically:

  • Theoretical factor models and correlation matrices.
  • Statistical Analyses of emergence and extreme events in complex systems using unsupervised machine learning methods (i.e., Dimensionality Reduction, Matrix Decomposition, Data Clustering) with application to synthetic, economic, financial, and industrial data.

Professional Experience

I was previously a Lead Research Scientist within Discover’s (Now Capital One) Data Science Research team. My work focused on leveraging machine learning techniques to extract signals from large tabular datasets to predict risk for various financial products.

Key areas of expertise included:

  • Feature noise cleaning and feature selection in high-dimensional regimes.
  • Embedding and clustering very large datasets.
  • Explainability, fairness, and bias estimation methods for both supervised and unsupervised models.
  • Supervised learning model development for credit acquisition and anti-money laundering.
