Purushottam Joshi

Research Fellow
Nanodevices

After his Engineering degree from Gulbarga University, India, Purushottam worked at Ceramic Technological Institute, BHEL-EPD, Bangalore. He completed his PhD from the University of Leeds, UK and received Overseas Research Scholarship for his PhD studies.

Before joining the INL in Braga, Purushottam worked at Raja Ramanna Center for Advanced Technologies, Laird Technologies and Shriram Institute for Industrial Research. He has five patents and eighteen international journal publications and has expertise in product development and certification. Purushottam research interest includes photonic glasses, optical fibre devices (lasers, amplifiers and sensors), functional materials, nanomaterials synthesis, processing and characterisations. He also received young scientist award from Indian ceramic society.
