Short bio

Jonatha Anselmi is a permanent researcher at INRIA-Bordeaux (France), working in the team CQFD. He has received a PhD degree in computer engineering (Ingegneria dell'informazione) from Politecnico di Milano (Italy) in 2009, where he also received a BSc degree in 2003 and a MSc degree in 2005 cum laudem. He has held research positions at BCAM - Basque Center for Applied Mathematics (Spain), INRIA-Grenoble (France), and he has held visiting positions at Caltech (US) and IBM T.J. Watson (US).

Prospective PhD students

If you are a prospective PhD student interested in stochastic control and resource allocation algorithms for large-scale distributed systems, feel free to contact me.

Research

I'm interested in stochastic operations research applied to the performance optimization of distributed systems and in particular to the development of robust large-scale designs able to achieve a better exploitation of resources. Problems under investigation are:
  1. Randomized load-balancing, open- and closed-loop control of distributed multi-server queueing systems;
  2. Bottleneck analysis and optimization of communication and computer networks;
  3. Impact of rational behavior on the performance of communication networks.
For further details, see below some selected publications or the complete list of publications.
