Hi, I’m Josh Pearlson

I currently work in finance in NYC creating and applying advanced analytics to problems in fundamental and systematic investing. Previously, I graduated from Washington University in St. Louis where I studied Computer Science and Finance. My main interests are modeling, machine learning, and capital markets. I love meeting and connecting with new people, so feel free to email me or LinkedIn message me!
