About
I like understanding what's really happening in the data.
My work sits at the intersection of technical analytics and business problem solving. I enjoy digging into complex datasets, challenging assumptions, and translating the results into something stakeholders can actually use.
I completed my MS in Business Analytics at the University of Minnesota's Carlson School of Management in August 2026.
