David Siegel is a computer scientist, entrepreneur, and philanthropist. He is co-founder and co-chair of Two Sigma, LP.

Inspired by movies like “2001: A Space Odyssey,” Siegel was drawn to the nascent field of computer science at a young age, quickly developing a deep interest in programming. By the mid-1970s, at age 12, he was building memory and logic boards and learning to program a supercomputer at New York University's Courant Institute of Mathematical Sciences. As a freshman in high school, he also taught a programming course to high school students at an NYU summer program.

This early interest in computers sparked a life-long passion for building intelligent computational systems, reflecting a lasting belief in technology's potential to improve virtually every human endeavor.

After graduating from Princeton, Siegel received a Ph.D. in computer science from Massachusetts Institute of Technology (MIT), where he conducted research at the Artificial Intelligence Laboratory. Siegel went on to co-found Two Sigma, an algorithmic investment manager that applies cutting-edge technology to the data-rich world of finance.
