Her practice focuses on late stage financings, secondaries, and other corporate transactions for investors such as SoftBank and Temasek, and on investments for some of the top investors dedicated to impact, from “impact first” foundations to family offices to private equity funds.

She is an adjunct professor at Berkeley Law School, teaching a course on social enterprise, specifically the intersection of corporate law, governance and sustainability.
