Bio

E.S. Lohan received the M.Sc. degree in electrical engineering from Polytechnics University of Bucharest, Romania, in 1997, the D.E.A. degree (French equivalent of master) in Econometrics, at Ecole Polytechnique, Paris, France, in 1998, and the Ph.D. degree in wireless communications from Tampere University of Technology (TUT), in 2003. She is now Associate Professor at the Department of Electronics and Communication Engineering (ELE) at TUT and she is the group leader for the mobile and satellite-based positioning activities (signal processing part) at ELE. She is a recipient of an Academy of Finland fellowship grant and she has been an intermittent Visiting Scholar at Universitat Autonoma de Barcelona (UAB) since 2012. E.S. Lohan was involved with the EU FP6 project GREAT and EU FP7 project GRAMMAR focusing on mass-market satellite navigation receivers, and she is currently participating in the Marie Curie ITN network MULTI-POS as a scientist in charge and equality officer.

Research interests

Wireless location techniques based on Signals of Opportunity (in particular WiFi indoor location), GNSS receiver architectures and multipath mitigation, and cognitive spectrum sensing for positioning purposes.
