Current Research Interests

Dr. Hippalgaonkar’s interests are in designing functional materials, especially for energy applications. He has fundamental knowledge in solid state physics, 1D (nanowires), 2D (TMDCs) as well as inorganic-organic (hybrid) materials. His approach to materials by design is built on creating and utilizing materials data by high-performance computing and high-throughput experiments to synthesize and characterize materials for optical and electronic properties.  In addition, machine learning and data science can potentially be used for materials discovery. His background is in transport properties of materials specifically in understanding their thermal, optical and thermoelectric properties. He is keen on developing tools such as process optimization, design of experiments and materials and process fingerprinting from materials development to device applications.

Keywords - Materials by design, high-performance computing, high-throughput experiments, energy materials, nanoscale heat and charge transport.
