Nagendra Singh Chauhan
Nagendra is a Research Fellow in the Nanochemistry Group of the Department of Micro & Nanofabrication at INL. He is working towards the development of unconventional thermoelectrics based on self-organised binary nanocrystal superlattices. His area of expertise includes bulk nanostructured thermoelectrics for targeted synthesis of both new and existing thermoelectric materials with optimal transport properties for high thermoelectric performance. Before joining INL, he was a Senior Research Fellow in the Advanced Materials & Devices Metrology Division at CSIR-NPL, India.
He holds a PhD in Engineering Sciences from CSIR-National Physical Laboratory, India in the field of mid-temperature thermoelectrics materials for power generation. During his PhD, he has worked extensively towards the design and development of high-performance and cost-effective materials and devices for thermoelectric energy generation, based on Half-Heuslers, Selenides, Tellurides, Skutterudites, Zintl, SiGe, etc. He was actively involved in materials metrology and standardization activities at CSIR-NPL, India (National Measurement Institute of India). He graduated in B.E (Mechanical) with distinction from Savitribai Phule Pune University (formerly, University of Pune), India and has worked on evaluation of “Stiffness and Vibration Isolation for Engine Isolators” in Vehicle Integration- Heavy Commercial Vehicles group at Engineering Research Centre, Tata Motors Limited, Pune. He obtained M. Tech (Material Science & Technology) from Maulana Azad National Institute of Technology, India and has worked on numerical study of heat transfer behaviour in nanofluids using Monte-Carlo simulation. He is also trained in metallurgical and non-destructive examination of structural failures by fatigue & wear at Research Design & Standard Organization, Lucknow (Indian Railways).
