Biography

I was born, as the eldest of five, in Saint-Petersburg, a beautiful Russian city in the North-West. In 2002, I have graduated from Saint-Petersburg State University, Mathematical-Mechanical faculty with “Specialist” Diploma (an equivalent of Master degree) in Computer Science. In years 2001-2003, I was on internship at School of Computing, National University of Singapore, which I eventually joined as PhD candidate in July 2003. In 2007, I spent 6 months as intern at FX Palo Alto Laboratory (FXPAL).

I officially graduated with PhD in April, 2011 and in May 2011 joined MMSPG group@EPFL as a postdoc.

During my PhD, I worked under the supervision of Dr. Wei Tsang Ooi.

You can view my CV [PDF] (updated in May 2015) and Research Statement [PDF] (updated in May 2015).
