Tatsunari Watanabe

Tatsunari Watanabe is an Assistant Professor of Mathematics at Embry-Riddle Aeronautical University, Prescott. He helps students visualize and understand mathematical concepts so that they can apply the ideas outside the field of mathematics. Prior to coming to Embry-Riddle, he taught numerous math courses including calculus, linear algebra, and differential equations at Duke University and Purdue University. Watanabe holds a B.A. in Pure Mathematics from UC, Berkeley and a Ph.D. in Mathematics from Duke University. 

Outside teaching and research, Watanabe enjoys playing soccer and outdoor activities such as hiking, river canoeing, and trail run. He is also the faculty advisor for the Club Soccer at the Prescott campus.
