Description

Namaste, Hola, & Welcome from G.V. Pavan Kumar.
Pratidhvani (ಪ್ರತಿಧ್ವನಿ/प्रतिध्वनि) means reflection or resonance (of sound). Here, the aim is to resonate with knowledge & humanize science.

The podcast conversation has two themes:
1) Intellectual journey of scientists, philosophers and historians of science;
2) History & Philosophy of Physical Sciences & Technology

I am a Professor of Physics at the Indian Institute of Science Education and Research, Pune, India.
I run this podcast in my personal capacity.

This episode is based on an essay by G.V. Pavan Kumar - to be published in the journal Resonance (March 2025)
Vivek is a Chemist and Professor at TIFR-Bombay : https://www.nanocat.co.in/prof-vivek-polshettiwar.htmlVivek’s research focuses on advanced nanomaterials,nanocatalysis, and climate change. He envisions developing next-generationcatalysts by controlling the shape and morphology of nanomaterials to optimizeactive site exposure. His team synthesizes nano-materials like metals, metaloxides, silica, titania, and plasmonic metals with tailored shapes for use asnano-catalysts in combating climate change. The ultimate goal is to advancecatalysis research by creating non-precious metal-based nanocatalysts.His group is dedicated to designing novel nanomaterialcatalysts that address climate change challenges effectively.In this episode, we explored his intellectual journey andlearn what catalyzes him to do what he does.Watch/Listen as we humanize science.References: [1]“Prof. Vivek Polshettiwar,” Nanocatalysis Laboratories.Accessed: Feb. 11, 2025.
