His research interests are in data science, machine learning, networks, and multi-agent systems, with applications in the broad area of information systems and networks. He has made contributions in the area of scalable algorithms for data processing and performance evaluation of computer systems and networks, in particular, in the areas of incentives and online services, distributed computing, network resource allocation, transport control protocols, and peer-to-peer networks.
He was awarded the 2010 ACM Sigmetrics Rising Star Researcher award, and the 2005 ERCIM Cor Baayen Award. He received the IEEE IWQoS 2007 Best Student Paper Award (with Shao Liu and Dinan Gunawardena), the IEEE Infocom 2005 Best Paper Award (with Jean-Yves Le Boudec), the ACM Sigmetrics 2005 Best Paper Award (with Laurent Massoulie), and the ITC 2001 Best Student Paper Award (with Jean-Yves Le Boudec). He delivered numerous lectures and seminars in both academia and industry. He taught several editions of a computer networking course to the undergraduate computer science program at the University of Split. He taught two editions of a course on contest theory within Part III of Mathematical Tripos (master program in mathematics) at the University of Cambridge. He authored the book ``Contest Theory: Incentive Mechanisms and Ranking Methods,'' Cambridge University Press, 2016.
