I graduated from the Erasmus Mundus Master of Science in Photonics programme which involved a year in Belgium (Ghent University and Vrije Universiteit Brussel), and another year at KTH Royal Institute of Technology, Stockholm.
I did my undergraduate study in Engineering Physics at Indian Institute of Technology Madras, India.
My PhD research involves tuneable lasers for upstream data transmission in optical links. I aim to engineer a tuneable laser that will go inside Optical Network Units (ONUs) in the consumers' premises connected to a Long Reach Passive Optical Network (LR-PONs) that is (arguably) the future of optical communication links. It ties on to the European Union research project - DISCUS

Master Thesis - KTH Royal Institute of Technology, Stockholm, Sweden - 2012
Supervisor: Prof. Urban Westergren
This thesis work is an extension of the Travelling Wave Electro-absorption Modulators (TWEAMs) developed as part of the EU FP6-IST project HECTO partly funded by the European Commission. I investigated and showed the possibility of extending the use of the modulators to incorporate phase modulation formats such as DPSK from the current On-Off Keying (OOK) capability.
Summer Internship - Institute of Photonic Technology, Jena, Germany - 2011
Guides: Prof. Christoph Krafft and Dr. Christian Matthäus
As part of the internship, I assisted with work involving culturing cancer cells, subjecting them to different drug delivery conditions and subsequently studying the intake of the drugs using Raman and FTIR spectroscopic techniques.
Bachelor Project - Indian Institute of Technology Madras, Chennai, India - 2010
Advisor: Dr. N. Krishna Mohan
I developed, as part of my undergraduate project work, an automated laboratory setup to perform displacement measurements using Digital Speckle Correlation.
Student programme at National Centre for Radio Astrophysics, Pune, India - 2009
Guides: Prof. Yashwant Gupta and Dr. Jayanta Roy
I was stationed at the institute's observatory - Giant Metrewave Radio Telescope (GMRT), the world's largest array of radio telescopes at metre wavelengths. I worked on various DSP based filtering algorithms to mitigate the Radio Frequency Interference present in the signals received by the telescope.
