I am a PhD candidate in the ECE department at Northeastern University and part of Dr. Jennifer Dy’s Machine Learning Lab at the SPIRAL research center. I’m broadly interested in improving transparency in black-box prediction models, specifically in relation to interpretability and uncertainty quantification.

I collaborate with Dr. Michael H. Cho’s research lab at Brigham & Women’s Hospital in applying machine learning methods to various challenges related to Chronic Obstructive Pulmonary Disease (COPD). COPD is a lung disease commonly associated with smoking and long-term exposure to lung irritants. We work with multiomics, spirography, and lung imaging to improve subtyping, disease progression, diagnosis, etc.

Prior to Northeastern, I completed my MS in Statistics at the University of Illinois at Urbana-Champaign and my BS in Economics and Business Administration at UNC Chapel Hill. My industry experience includes internships with Optum AI, Wayfair and Blue Cross Blue Shield, as well as lead analyst roles in the Oil & Gas, Wind, and Power Generation businesses of General Electric.
