Early life and education edit

Sandip Tiwari was born in Ahmedabad, India, received his BTech from Indian Institute of Technology, Kanpur in 1976. He received his M.Eng. at Rensselaer Polytechnic Institute and PhD at Cornell University in 1980.[citation needed]

Work and academic career edit

His early research career was at IBM's Research Division until 1999. During this period, he did the early work on compound semiconductor transistors and co-developed the first SiGe transistor.[1][2] He also pioneered various quantum and nanoscale devices, such as the nanocrystal memory.[3] The first demonstration of SiGe transistor was honored as IEEE International Electron Devices Meeting (IEDM) Top Industry Innovation of 1987.[citation needed] His work on nanocrystal memory was one of the 50 most-cited papers in the history of Applied Physics Letters in 2013.[4]

At Cornell University, his Nanoscale ElectroScience Research Group[5][6] focused on adaptive approaches for low power design,[7] three-dimensional integration,[8][9] inexact computing,[10] and Bayesian implementations[11][12]
