Research Interests

My research interests include applied econometrics, causal inference, and machine learning, particularly their applications to the study of markets and competition. My background is in mathematics and economics, and I am currently pursuing a master’s degree in Applied Statistics at Penn State.

I am seeking research assistant positions in economics and related fields as well as opportunities in economic consulting.

Selected Research

Assessing Fare Changes After the Delta–Northwest Merger: Evidence and Limits

Independent research · Writing sample · September 2026

Using DB1B-derived market summaries from 2005–2010, I examine fare changes on routes with substantial pre-merger Delta–Northwest overlap relative to a defined comparison group. The baseline estimate shows a 5.72% relative fare decline after completion. Differences in pre-merger fare paths and sensitivity to sample definitions limit a causal interpretation.

Data and methods

I construct passenger-weighted route-quarter fares, estimate route and quarter fixed-effects models, and examine event-study patterns and sensitivity to sample definitions and weighting. The technical supplement documents data cleaning and definitions; the repository includes code, saved results, and the original input dataset with source attribution and a checksum.
