Sheila Prasad, Professor

Professor Prasad received the B.Sc. degree from the University of Mysore, India and the S. M. and Ph.D. degrees from Harvard University, Cambridge, Massachusetts.

Professor Prasad has done research in electromagnetic theory and applications including antennas. She is co-author with R. W. P. King of the book "Fundamental electromagnetic theory and applications," which was published by Prentice-Hall in 1986. Her current research areas are: microwave and high speed semiconductor devices and circuits and optoelectronic circuits. On-going research projects include large signal characterization , modelling and optimization of heterojunction bipolar transistors (HBT's) for applications in high power and personal communication circuits, application of neural networks to semiconductor device characterization and characterization of optoelectronic devices and integrated circuits.
