Profile

Prof. Hasan has been working as a full Professor since 2005. He completed his PhD from the University of Edinburgh, UK on a Commonwealth Scholarship in the area of "Low Power Architectures for Signal Processing and Communications"He also worked as a Visiting Researcher on his own Royal Academy of Engineering, UK funded project on "Low Power FPGA' in the same University. He has published 123 papers in refereed journals and conferences with more than 200 citations. This also includes five IEEE Transactions and 37 other journal publications. He received "Paper of the Year Award" by the Editors of the famous International ETRI Journal for his paper entitled "High Performance Low power FFT cores along with a best International conference paper award. He has supervised three PhDs and currently supervising one more along with many M.Tech. Dissertations. His research interests are in Nanoelectronics, Ultra low power design, Spintronics, Battery-less electronics,Variability aware design.

About Department

The Department of Electronics Engineering was established in 1988. It has made significant progress since its inception and attained the status of a pioneering Department particularly in the Faculty of Engineering and Technology and in general in the University. The department has credit of being first department in the faculty of Engineering & Technology to have the Departmental Research Support (DRS) scheme funded by UGC. Currently phase-II of this scheme is running in the department.
The Department offers an undergraduate (B. Tech.) course in Electronics Engineering and two postgraduate (M. Tech.) courses in (1) Electronic Circuits & Systems Design and (2) Communication & Information System. The subjects offered at both, UG & PG levels cover almost all upcoming and areas of significance viz. Analog & Digital Electronics, Microelectronics, VLSI Design & Technology, Electronic Instrumentation, Control Systems, Analog & Digital Communications, Microwave Engineering, Radio, Television, Radars, Optical Communication, Satellite Communication, Mobile Communication, Computer Communication Networks, Image and Signal processing, etc. The well-equipped laboratories supplement a large number of these courses.
Beside UG & PG programmes the Department encourages research activities in the emerging areas and provides facilities for the same. In addition, the faculty members are also working in collaboration with universities abroad on joint research projects. Also some faculty members regularly visit abroad for collaborative research. The Teaching Staff of the Department has supervised a good number of Ph. D. theses and M. Tech Dissertations since its inception.
