Lakmal Buddika Meegahapola

Doctoral Assistant at EPFL, Research Assistant at Idiap Research Institute

I'm a 1st year PhD student at School of Engineering, École polytechnique fédérale de Lausanne (EPFL) and a Research Assistant in Social Computing Group at Idiap Research Institute advised by Prof. Daniel Gatica-Perez. I'm interested and experienced in using Data Science and Analytics, Machine Learning for research in Ubiquitous and Mobile Computing. Currenty, I am part of the large scale EU-funded project "WeNet - The Internet of US", and my research revolves around "Diversity-Aware Machine Learning for Rich Mobile Sensing Data".

Before starting my PhD, I worked as a Research Engineer at SMU-CMU Living Analytics Research Centre in Singapore Management University, Singapore under the supervision of Prof. Archan Misra. I got my BSc Engineering degree (Computer Science and Engineering) from University of Moratuwa, Sri Lanka.

My work has been recognized at prestigious events such as Microsoft Imagine Cup World Finals , Asia Pacific ICT Alliance, and National Best Quality ICT Awards (Sri Lanka), and has been covered by local and international press. Further, I was part of the Sri Lankan International Olympiad team for Astrophysics.
