During my time at Columbia, I have immersed myself in the PE ecosystem both academically and experientially—through courses such as Private Equity Finance and Turnaround Management, and hands-on work in the PE Field Study and M&A Class. Beyond the classroom, I have deepened my investing skills through internships at One Rock Capital Partners and GLIN Impact Capital, working on live deals from carve-outs to growth equity, while also leveraging my prior experience at Mitsubishi in evaluating and developing businesses globally.
