About

Dr. Pushpapraj Singh has received the M.Sc. (Electronics) from Aligarh Muslim University Aligarh and M. Tech. (Solid State Technology) from Indian Institute of Technology Madras, India in 2004 and 2007, respectively. For the M.Tech. project (jointly under Prof. Nandita DasGupta and Prof. M.S. Ramachandra Rao), he was involved in the designing, simulation and in-house fabrication of MOS capacitors with different gate materials. Pulsed laser deposition method is used to deposit the HfO2 (also co-doped HfO2) and MOS capacitors are fabricated and characterized. After M. Tech., he has moved to Nanyang Technological University (NTU) Singapore in December 2007 for his PhD research work 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 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
