About me
Prof. E.S. Lohan received an MSc degree in Electrical Engineering from Polytechnics University of Bucharest (1997), a DEA degree in Econometrics at Ecole Polytechnique, Paris (1998), and a PhD degree in Telecommunications from Tampere University of Technology (2003). She is now a Full Professor at the Electrical Engineering unit at Tampere University (former Tampere University of Technology) and a Visiting Professor at Universitat Autonoma de Barcelona (UAB), Spain (spcomnav group). She is leading a research group on Signal processing for wireless positioning (www.cs.tut.fi/tlt/pos). She is a co-editor of the first book on Galileo satellite system (Springer "Galileo Positioning technology"), co-editor of a Springer book on "Multi-technology positioning", and author or co-author in more than 250 international peer-reviewed publications, 6 patents and inventions. She is also an associate Editor for RIN Journal of Navigation, IET Journal on Radar, Sonar, and Navigation, IEEE Journal of Indoor and Seamless Positioning and Navigation (J-ISPIN), and IEEE Aerospace and Electronic Systems Magazine. She was the coordinator of the H2020 MSCA European Joint Doctorate A-WEAR (www.a-wear.eu), 2019-2022.
