I am a Computer Scientist developing efficient and scalable computing systems to tackle societal and scientific challenges. 

I am a Lecturer (~ Asst. Professor) at Queen's University Belfast and a Fellow of the ECIT Institute. I am an Honorary Lecturer at the University of St Andrews and a Visiting Researcher at the British Telecommunications (BT) Ireland Innovation Centre.  

I am the Principal Investigator of the Edge Computing Research Hub generously funded by Rakuten Mobile, Japan

I am an Eaton Fellow, a Santander Scholar and an alumnus of the Royal Society of Edinburgh Scottish Crucible and the Felix Scholarship. I am a Fellow of the Higher Education Academy.

I was born in Doha, Qatar to immigrant parents from Kerala, India. I did my schooling in Doha and Kerala and was fascinated by the 3C's - Crosswords, Cricket and Coins. Academically, my interests were in the Science subjects and Maths, but as a student I never felt much appreciation for the social sciences or humanities. A Commodore-64 given by an aunt and uncle on my 9th birthday sparked my ever growing interest in Computers. 

After leaving school, I went on to do an undergraduate degree at Trivandrum, India. The four years spent away from home made me more fascinated with computers, but also helped me focus on developing my soft skills and seeking answers to more important questions of life. Subsequently, I worked in Chennai, India, for a multi-national company. I enjoyed it, but still had a desire to pursue my academic passions. 

When I was offered a place to do a Masters at Reading, England on the Felix scholarship, the interview question - "how is your research going to benefit a poor farmer?" was eye opening. This was the first time I had ever considered the societal aspects of computer science. These became guiding principles of my research as I then went on to do a PhD at Reading. 

After obtaining a PhD I was privileged to gain post-doctoral experience at Halifax in Canada, St Andrews in Scotland and Belfast in Northern Ireland. During this time I submitted a ton of faculty job applications worldwide, with little to no success. I even came close to leaving academia for an opportunity in a horticulture business. Over five years I was interviewed for six lectureships and was offered three.

Finally, I joined Queen's University, Belfast where I am realising my vision: "to advance computing by tackling scientific and societal challenges". My Christian faith invigorates my commitment to useful research. I now live in the historic harbour town of Carrickfergus with my wife and four children.
