I am a member of the Management Committee of the COST Action CA16228 “European Network for Game theory”
and Vice-Leader of Work Group 1: Algorithmic Theory of Network games
I have taught Applied Mathematics, Introduction to C++ (3 times) and Mathematics for Communications (twice) at De Montfort University, UK and Game Theory at the Unversity of Saarland, Germany.
My research area is in Algorithms and more specifically Algorithmic Game Theory and Mechanism Design.
My research focuses on designing auctions for multi-parameter domains lately I am interested in designing mechanisms for cryptocurrencies based on the blockchain technology and on Differential Privacy.
My PhD and a some of my follow-up work focuses on an auction for allocating jobs, the game-theoretic version of the seminal scheduling unrelated machines problem. The machines are selfish and won't reveal their processing times for the jobs without getting the correct payment. So in fact the setting is more like the setting of an auction for selling multiple distinct items. Which are the possible mechanisms we can use for the allocating the tasks? I have made crucial steps toward resolving this very important problem however the lower bound I gave in 2007 still hasn't been improved.
Other problems I find tempting are adword auctions, cost sharing, secretary problems, voting, computation of equilibria. I also enjoy computational algebra and geometry.
