About me

I was born and raised in Kalpathy - a heritage village in Kerala, INDIA. My research background includes electrochemical energy storage devices, photocatalysis and sensors. Besides working, I like to travel and explore food & culture, music & attending live concerts, playing mridangam (Indian classical drum). Furthermore I like organizing activities and games with my friends. I speak English, Hindi, Telugu, Malayalam and Tamil.

About my research

It has been always challenging to understand catalytic chemical reactions at molecular level in real time, that too for reactions occurring at very high temperature. My PhD research is to develop surface-enhanced Raman Spectroscopy (SERS) in combination with material synthesis for high-temperature in-line monitoring of gas-phase products formed in real time. The focus of the research is to self-assemble thermally stable noble metal nanorods as SERS sensing particles along with suitable colloidal nano-catalyst, such that catalysis & SERS sensing are combined and will allow for not only following the catalytic events, but also deactivation pathways of the catalyst. Major part of the project is to improve SERS sensing at high temperature.
