About

Dr. Singh has received M. Tech. (Solid State Technology) from Indian Institute of Technology Madras, India in 2007. He moved to Nanyang Technological University (NTU) Singapore in January 2008 for his PhD under Prof. Miao Jianmin. In his PhD thesis work, he conducted extensive work for the piezoresistive sensitivity enhancement in silicon nanowires, planar and nanowire transistors. He also introduced the novel concept of gate-all-around junction less transistor as an improved sensing element for improving the strain detection limits.

After PhD, Dr. Singh has continued (since December 2011) his research work as a Research Scientist in A*STAR Institute of Microelectronics (IME), Singapore while working on several MEMS projects (MEMS based switches and non-volatile memories, piezoresistive and acoustic wave pressure/force sensors, inertial sensors, miniaturized medical devices). He joined CARE, IIT Delhi as an Assistant Professor in September 2016.
