Mani Vaidyanathan received the B.A.Sc. and M.A.Sc. degrees from the University of Waterloo, and the Ph.D. degree from the University of British Columbia. He has held the positions of Assistant Research Scientist at the University of California - San Diego, working in the area of radio-frequency electronics, and Visiting Assistant Professor at Purdue University, working in the area of computational nanoelectronics. He is currently a Professor and Program Director of Engineering Physics at the University of Alberta.
Dr. Vaidyanathan’s research interests are in understanding nanoscale transistors and circuits for future technologies. State-of-the-art modeling and simulation approaches, such as the semi-classical Boltzmann transport equation (BTE) and the fully quantum-mechanical non-equilibrium Green’s function approach (NEGF), are used to assess the performance potential and operating physics of emerging transistors. Work is also underway in the area of radio-frequency (RF) circuits. Collaborators include local experimentalists, academics from Europe, and industrial partners in North America, including IBM and Qualcomm.
