Biography

Welcome to my website! My name is Dr. Chinna Devarapu, and I am a research fellow in the field of nanophotonics.

I have always been fascinated by science and technology, and that passion led me to pursue career in Science. I received my M.Sc. in Physics from Banaras Hindu University and my M. Tech in Applied Optics from the Indian Institute of Technology Delhi. While at IIT Delhi, I received a DAAD fellowship to complete my Master’s thesis project at the Technical University of Berlin. During this time, I developed a confocal microscope for use in direct laser lithography.

I continued my education with a Ph.D. in Physics at the University of Exeter, where I focused on lossy photonic crystals and metamaterials for near-perfect absorption in the infrared regime. After completing my Ph.D., I joined the Nanophotonics group at the University of St Andrews as a post-doc. In 2016, I moved to Cork, Ireland, where I currently work as a researcher fellow in the Nanophotonics Research group at Munster Technological University.

Throughout my career, I have received over $1 million ($600,000 as a PI) in research funding. I have published 12 research articles, and hold 2 patents and 11 invention disclosure forms.

I lead two commercialization projects (one as a PI) that aim to bring the research outputs from our lab into the real world to solve interesting problems using light. My goal is to miniaturize bulky, expensive benchtop equipment into low-cost, handheld instruments using PIC. Currently, I am working several international and industrial projects, employing this PIC technology for applications ranging from gas sensing, lasers, medical devices etc.

In my free time, I enjoy experimenting with electronics, building apps, and 3D printing objects. I also like to create low-cost, open-source hardware equipment and build cool robots.

Projects

*
PixCan
The project aims to develop a new type of testing platform for photonic integrated circuits (PICs) that are used in data centers. These circuits, which are used to exchange data between server racks in data centers, are currently based on technology with high power consumption and large size.

Innovative Water Monitoring
During this project, we equipped a small boat (buoy) with a Raman spectrometer to monitor the water quality. We focused primarily on two main research areas: i) real-time monitoring of pathogens in water ii) real-time monitoring nutrients Nitrogen and Phosphorus (N&P) in water.
Innovative Water Monitoring
ODX: an ultraportable wireless continuous bacterial growth monitoring device.
Continuous monitoring of bacterial growth in aqueous media is essential in various fields, but current methods using benchtop spectrophotometers are limited by their large size and require labor-intensive multiple samplings. To address these issues, we have developed an optical density measuring device (ODX) based on a generic fitness tracker. ODX is ultra-portable, low-cost, and can be used in bacterial incubators for real-time monitoring, even while shaking is in progress. We have tested ODX with different bacterial types and growth conditions and found that it performs comparably to a commercial benchtop spectrophotometer. We have also developed a smartphone application that allows users to be notified when bacterial concentrations reach targeted values. With its potential for automation and mass production, ODX has numerous potential applications in biotechnology research and industry.
