Teaching

I started my teaching career as a Lecturer in the Department of EEE, BUET back in 2009 and since then I have been a Faculty member of this Department. From 2012-2016, I was on study leave for my Ph.D. at the University of Michigan, Ann Arbor, USA. There, in Winter 2016 semester, I served as a Graduate Student Instructor in the Electrical Engineering and Computer Science (EECS) department. Upon receiving my Ph.D. in August 2016, I returned Bangladesh and resumed my teaching career here in the Department of EEE, BUET.  

Regarding my teaching philosophy, though it largely depends on the subject and context, in general, I like to blend the traditional chalk-and-talk technique with online or offline educational aids and resources. Irrespective of the method, I have seen that the best outcomes are always attained when the students are made to actively engage in the teaching-learning process.

In this page, I have listed several of my instructed courses, along with the course content. For relevant resources, students are suggested to visit the respective Teams portal of BUET.
