About John

I am a quantitative researcher at Susquehanna International Group. Prior to SIG, I was at MIT Lincoln Laboratory in Group 32 (Advanced Concepts and Technologies) where I worked on pattern recognition and techniques from artificial intelligence. I earned my Ph.D. from the MIT Applied Mathematics Department in 2001, studying partial differential equations. When not working, I read quite avidly and enjoy spending time with my wife and two daughters.

On these pages you will be able to find a lot about my technical interests. I hope you enjoy them and find them helpful to what interests you. My solution manuals can be found here.
