About the course
A course in engineering physics for students pursuing a B.Tech/B.E course. The topics covered are wave optics and LASERS which will be extended soon.
About the instructor
The instructor of this course is Dr Pooja Singh who is currently working as Assistant Professor in College of Technology & Engineering, Udaipur. Dr Singh completed her PhD from CSIR-National Physical Laboratory, New Delhi and thereafter joined Indian Institute of Technology, Delhi as a Post-Doctoral Fellow. Her research interests include Ferroelectrics, Semiconductor devices, metal-semiconductor junctions, Non-volatile memories, and strongly correlated systems.
She had published several articles in international journals such as J. Appl. Phys., Thin Solid films, J. Mater. Sci., J Alloys Compd., J. Magn. Magn. Mater., J Lumin. She has completed her post-graduation (MSc) from the Department of Physics & Astrophysics, University of Delhi. She had qualified national levels competitive exams such as GATE and CSIR-NET.
She worked in Gautam Buddha University, Greater Noida where she taught B. Tech, BSc, and MSc courses viz. Solid State Physics, Thermal Physics, Statistical Mechanics & Engineering Physics. She is a good teacher and motivator. All course materials including lecture notes, video lectures, and PowerPoint presentations will be available on this page.
