Jean Takche

Dr. Jean Takche is an associate professor of mathematics in the Department of Computer Science and Mathematics. He joined the Lebanese American University in 1990 as an assistant professor. He is a TL/MEPI Academic Coordinator since 2017. He was a staff advisor for USP/USAID from 2014 until 2018. He served in the University Senate from 2011 until 2014. He was a professor at the Lebanese University from 1985 until 1990.

Dr. Takche‚Äôs research interest was algebraic complexity, and he is now working in a different area, namely non-smooth analysis and its application to control theory.  

He teaches Calculus, Differential Equations, Linear Algebra, Algebra, Applied Statistics, Probability & Statistics, and Numerical Methods.

In his free time, he enjoys chess, bridge and listening to soft music.
