Dr. Jean Takche is a non-tenured continuing 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’s been 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’s 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.
