Matthias Grossglauser

Matthias Grossglauser (born 1969 in Niederbipp, Switzerland) is a Swiss communication engineer. He is a professor of computer science at EPFL (École Polytechnique Fédérale de Lausanne) and co-director of the Information and Network Dynamics Laboratory (INDY) at EPFL's School of Computer and Communication Sciences School of Basic Sciences.

Career Grossglauser studied communication systems and electrical engineering at EPFL and at Georgia Institute of Technology, respectively, and graduated from both with Master's degrees in 1994. He received a PhD with highest honors in computer science from the Pierre and Marie Curie University (UPMC) in Paris in 1998. His PhD thesis on "Control of Network Resources over Multiple Time-Scales" (in the French original: Contrôle des ressources de réseaux sur des échelles temporelles multiples) was supervised by Jean-Chrysostome Bolot. He then joined AT&T's Networking and Distributed Systems Laboratory (Shannon Labs) at Florham Park, New Jersey as a principal research scientist. In 2003, he moved as an assistant professor to EPFL's School of Computer and Communication Sciences. In 2007, he joined the Nokia Research Center (NRC) in Helsinki first as director of the Internet Laboratory, before becoming head of Data Insight program and member of the CEO Technology Council in 2009.

Mobility Mining: Grossglauser investigates the application of machine learning to harvest the rich structure of mobility date generated by millions of users on the move through their smartphones. He is interested in applications such as location-based advertisement, navigation and transportation, and augmented reality.

Epidemics: Epidemic models enables the study of dynamics and long-term asymptotics of epidemic processes, such as infectious diseases or the dissemination of ideas in social networks. It also explores measure such as vaccination to slow the process, or deliberate infections to optimize the spread of an opinion. In this field Grossglauser is interested in estimation problems on epidemics under monitoring budget constraints.

Discrete-choice models: He examines new implementation and stochastic models for choices, comparisons, and rankings in online contexts, as well as their issues of large-scale inference and active learning.

Active Learning: He investigates and implements earning methods that balance the competing goal of gaining more knowledge by exploring new data on the fly. Goal is an ad hoc optimisation of the learning process based on the current state of knowledge.

Network traffic measurement: Grossglauser jointly with Nick Duffield is the developer of the trajectory sampling (TS) method. It aims at making traffic measurement for network operators more efficient and less error-prone, while being compatible with existing IP protocols and packet formats. Its development led to the formation of the PSAMP working group at the IETF that standardized TS, and has since become an official IETF standard.
