About Me

Welcome! I hold a Ph.D. in Political Science and International Relations from the University of Southern California. I also hold a Master of Science in Applied Economics and Econometrics (MS AEE). I have a strong mixed methods background through my experience working with survey data, A/B testing, survey experiments, interviews, focus groups, text analysis, vector autoregressions (VAR), time series data, and multilevel-regression analysis with postratification frames (MRP).

Currently, I pursue my career as a mixed methods UX Researcher. I lead both qualitative and quantitative research initiatives, supporting product development and shaping business strategy. I have a track record of running rapid product research cycles, enabling fast and iterative product development. One of my key strengths is my ability to build and scale robust research practices in new domains and teams. 

Prior to my doctoral education and career in UX, I worked as a public affairs and strategic communications consultant and analyst for international private firms from the pharmaceutical, technological, luxury retail, financial, and investment sectors.
