Hi, I am Praveen.

A Postdoctoral Researcher.

Working at the Institute of Physics, University of Tartu, Estonia, under the ERA Chair CIPHR project. Currently I'm focusing on the development of mid-IR metamaterials for computational imaging. We use theoretical aids to design a potential metamaterial and then use lithography techniques to fabricate them. We look forward to employing these systems for practical applications such as multi-layer tissue imaging.

My primary area of interest is developing potential organic and hybrid semiconductor systems such as metal-organics and perovskites for optoelectronic applications. I use density functional theory to explore materials at the molecular level and tweak them to suit our requirements. These molecules are fabricated as devices and investigated for applications such as OLETs, low-power x-ray sensors, or photodetectors.
