HELLO!!!! I am working as a Postdoctoral Research Scientist at Khalifa University, Abu Dhabi in the Department of Aerospace Engineering. I have completed my PhD from the department of mechanical engineering at Indian Institute of Technology Patna (IIT Patna), one of the premium institution in the field of research. My research area includes characterization and fracture analysis of soft materials. In recent times, soft materials are extensively used in the development of artificial muscles, artificial skins, soft robotics, soft sensors, actuators and energy harvesting devices. My work also involves product development which includes Testing machines, Energy Harvesting Devices and Micro Pump etc. using soft materials. I have published research papers in Q1 journals like Polymer Testing and filed a patent for 'Biaxial Tensile Testing Machine' in the office of India Patent. I have presented articles in international conferences in India and abroad both. During my research I have actively worked on different projects at IITP including INDO-SINGAPORE project supported by DST, Government of India under a research project No. INT/SIN/P-03
Research Areas: Electro-mechanical Characterization, Fracture Analysis, Dielectric Elastomer, Morphing Wing, Filled Elastomers, Biaxial, DIC, Polymer Physics, Crack Propagation, Product Development
Teaching Interests: Engineering Mechanics (EM),Mechanics of Materials (MOM), Design of Machine Elements (DME), Refrigeration and Air conditioning (RAC)
