Thomas Frank Biography and Net Worth

Thomas Frank is the executive vice president and CIO of Timber Hill LLC, an organization he joined in 1985 as a software developer. 

Frank joined Timber Hill immediately after receiving his Ph.D. from MIT, and he helped to spearhead the development of software for risk management and trading systems, as well as automated pricing. He became vice president in 1990 and worked to orchestrate the adoption of hand-held computers on trading floors, the delivery of high-ending trading tools to a variety of traders and investors, and fully electronic trading systems. In his current role as executive vice president and CIO, Frank concentrates on the development of brokerage systems. 

Frank spent his first 12 years at MIT working towards his undergraduate degree and Ph.D., the first of which he received in 1977 and the second in 1985. The majority of his time at the institution was spent building analysis software and experimental instruments. He was also invited to spend two years at the renowned Fermilab physics research facility in Batavia, IL. 

Inspired by his experience at MIT, Frank and other members of the Patrons of Physics Fellows have made it their goal to ensure that most first-year students at MIT can focus on choosing a path of study rather than working as a teaching or research assistant thanks to monetary donations made by Frank and his fellow patrons. 

He currently serves as a member of OCC’s board of directors, serving on both the risk committee and the technology committee. He still calls Boston home, and often visits the MIT campus to attend physics lectures and events. He also serves as a member of the Physics Visiting Committee.
