DESCRIPTION:Prof. Nikolas GeroliminisProf. Tom Battin\nProf. Nikolas Gerol
 iminis:"Traffic congestion in smart cities with big data"Abstract:\nOur re
 search tackles the problem of modeling and optimization in large-scale con
 gested traffic networks in a holistic way  with an aggregated realistic r
 epresentation of traffic dynamics and route choice and multiple modes of t
 ransport. This talk will talk about the integration of big multi-sensor da
 ta\, the understanding of multimodal patterns\, the coordination and optim
 ization of urban efficiency for the travel of people. This is challenging 
 because cities are highly complex systems. This seminar will describe meth
 odologies to model and understand the collective behavior for different ty
 pes of urban systems. It will highlight under what physical properties the
  aggregated laws will provide reasonable description of congestion for sin
 gle- and multi-modal systems. It will also describe how to develop hierarc
 hical feedback control and optimization tools and investigate what type of
  real-time active traffic management schemes (congestion pricing\, vehicle
  restriction\, large scale traffic signal control) can improve mobility me
 asures in a city for cities of different structures.  The validation of t
 he methodologies and the traffic management schemes are conducted in vario
 us and complex city structures scenarios using data from large field exper
 iments and detailed simulations.Short Bio:\nProf. Nikolas Geroliminis is a
 n Associate Professor at EPFL and the head of the Urban Transport Systems 
 Laboratory (LUTS). Before joining EPFL he was an Assistant Professor on th
 e faculty of the Department of Civil Engineering at the University of Minn
 esota. He has a diploma in Civil Engineering from the National Technical U
 niversity of Athens (NTUA) and a MSc and Ph.D. in civil engineering from U
 niversity of California\, Berkeley. He is an Associate Editor for  Transp
 ortation Research  part C and he also serves in the editorial board of TR
 \, part B\, part C\, Journal of ITS and of many international conferences.
  He is a member of the Transportation Research Board's Traffic Flow Theory
  Committee. His research interests focus primarily on urban transportation
  systems\, traffic flow theory and control\, public transportation and log
 istics\, Optimization and Large Scale Networks. He is a recent recipient o
 f the ERC Starting Grant “METAFERW: Modeling and controlling traffic con
 gestion and propagation in large-scale urban multimodal networks”Prof. T
 om Battin:\n"Of biofilms and carbon: The beauty and challenges of reconcil
 ing scales in fluvial ecosystems"Abstract:\nBiofilms dominate microbial li
 fe in fluvial ecosystems. They are microbial “megacities”\, which harb
 our an astonishing biodiversity\, develop complex architectures and regula
 te critical ecosystem processes and functions. At the scale of Earth syste
 m processes\, stream and river ecosystems are now being recognized as majo
 r players of the global carbon cycle. Streams and rivers receive large ter
 restrial deliveries of organic carbon\, which microbes respire to carbon d
 ioxide and which is ultimately emitted into the atmosphere. In his Inaugur
 al Lecture\, Tom Battin will sketch recent developments and identify major
  research gaps in these apparently disparate fields of aquatic sciences. H
 e will then discuss possible avenues to fill these and to bridge apparent 
 scales between microbial biofilms and carbon cycling in streams\, based on
  current and future research in the new “Stream Biofilm and Ecosystem Re
 search Laboratory” at ENAC.Short Bio:\nTom Battin has spent the last fif
 teen years studying the microbial life and biogeochemistry in stream ecosy
 stems. He has pioneered the field of biofilm ecology and his work was cond
 ucive to bring streams and rivers as new players onto the map of the globa
 l carbon cycle. He received his PhD from the University of Vienna\, where 
 after several postdoctoral positions in the USA and Spain\, he got appoint
 ed Associated Professor and later Full Professor in Limnology. He was Visi
 ting Professor at the University of Uppsala and Guest Professor at the Uni
 versity of Applied Arts Vienna. He joined EPFL as Full Professor in “Eco
 hydraulics” in 2015.
