Instructor bio

Prof. Hitesh Shrimali

IIT Mandi
I am an associate professor in the school of computing and electrical engineering. Before joining IIT Mandi, I did B.E. from Nirma Institute of Technology (Ahmedabad), M.Tech. from IIT Kharagpur and Ph.D. from IIT Delhi. My M.Tech. and Ph.D. theses were under the guidance of Prof. Amit Patra and Dr. Shouri Chatterjee respectively. After that I joined STMicroelectronics (Greater Noida) as a senior design engineer. After having 2 years of industrial experience, I worked with Università degli Studi di Milano as a post doctorate researcher, under the guidance of Prof. Valentino Liberali. During post-doctorate experience, I was also associated with INFN [Istituto Nazionale di Fisica Nucleare] Milano.

Prof. Kushal K. Shah

IISER Bhopal
Dr. Kushal K. Shah completed his BTech in 2005 and PhD in 2009, both from the Electrical Engineering Department of IIT Madras. In 2009-10, he went to Weizmann Institute of Science in Israel for a post-doctoral fellowship. He joined Jawaharlal Nehru University (New Delhi) as an Assistant Professor in 2010 and in 2012, he was conferred with the GN Ramachandran fellowship by the university. In May 2012, he joined IIT Delhi as an Assistant Professor in the Electrical Engineering Department and moved to IISER Bhopal in August 2017 as an Associate Professor in the Department of Electrical Engineering & Computer Science. He was awarded the INAE Young Engineer Award in 2014. His primary research interests include Dynamical Systems, Signal Processing and Artificial Intelligence.

He also runs a YouTube channel called BEkushal containing short and interesting videos on various topics relevant to college students: https://www.youtube.com/c/bekushal

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
