Lucas Kowalczyk

I completed my PhD in November 2018. My advisors at Columbia were Allison Bishop and Tal Malkin, and I served as the illustrious "Head of Cyber" for the Crypto Lab of the Columbia Computer Science Department. Check out some of my crypto research here: [Research]

I now work as a Quantiative Researcher at IEX, one of the newest US stock exchanges. Check out our blog here: Boxes + Lines

I am a captain emeritus of the Columbia University Ski Team. I love skiing.
