Tom is a financial analyst, portfolio manager, and freelance writer specializing in renewable energy and energy efficiency investing. 

Tom has a Ph.D. in mathematics from Purdue University where he wrote his thesis on Complex Dynamics, a branch of chaos theory. His study of chaos theory led to his conviction that knowing the limits of our ability to predict is much more important than predictions themselves, a lesson he applies to both climate science and the financial markets.
