About me

My core research interest is development of Neuromorphic Computing hardware for next generation of energy-efficient, intelligent and adaptive computing and sensing. More specifically, my team's research focus is Non-volatile Memories, synaptic weight elements and leaky-integrate and fire neuron components based on Back-end CMOS compatible Ferroelectric thin films and oxide or 2D semiconductor based heterostructures. My research experience and interest also includes Spintronic components like magnetic tunnel junctions and different other emerging solid state electronic devices including optoelectronic and flexible and wearable sensor components.
