My research area is in THz physics and engineering, focusing on THz devices/components, time-domain spectroscopy and medical diagnostic applications. In 2021, I joined the University of Warwick as a Research Fellow working under the supervision of Dr James Lloyd-Hughes, developing multi-pixel photoconductive emitters for THz beam shaping and steering. The multi-pixel PCE along with the polarization-resolved electro-optic detection (PR-EOS) system will be used to study the various biomaterials, particularly skin phantoms and differentiate between healthy versus cancerous tissues.

My PhD was on the Characterization of Skin-based THz Communication Channel for Nano-scale Body-centric Wireless Networks at the Queen Mary University of London in 2017 under the supervision of Dr Akram Alomainy and Prof Mike Philpott. My research focused on THz time-domain spectroscopy of 2D and 3D skin models and numerical modelling of THz short-range channels for a lossy medium like human skin.

Right after my PhD, I joined UKHSA's (UK Health Security Agency) Electromagnetic research group based in Chilton as a Radiation Scientist. I worked under Dr Azadeh Peyman and gained more industrial experience in 1) evidence-based research methodologies to assess exposure from non-ionizing sources of radiation and 2) Dielectric spectroscopy for understanding low-frequency (<1MHz) radiation effects on biological tissues. The strategic focus here was to carry out research to advance the knowledge about protection from the risks of radiation and support the UK government, public and other institutions on radiation standards and guidelines (more about UKHSA).

I am originally from Delhi, India and moved to the UK in 2012. When I am not in the lab, I keep myself busy with tennis, yoga and badminton.
