Mentoring and advising

I mentored four NYU Center for Data Science graduate students through a capstone project. At Meta I helped onboard and mentor junior ML engineers, and at Plated I led academic outreach, including sessions at NYU and Cornell Tech.

I have mentored through GrowthMentor and SharpestMinds, and on machine learning and AI through TeamUp.

I also advise early-stage companies and investors on machine learning strategy and on building a first ML team.

To ask about mentoring or advising, email me.
