Biography

Ignacio Roldan received his B.Sc. and M.Sc. in Telecommunication Engineering at the Universidad Politecnica de Madrid, Spain in 2014 and 2016. In 2018 he complemented his education with an M.Sc. in Signal Processing and Machine Learning at the same university. Ignacio has worked more than 5 years for Advanced Radar Technologies, a Spanish tech company focused on the design and manufacture of radar systems. In this period, he has been involved in several international projects developing state-of-the-art signal processing techniques for radars. In his last stage, he was focused on applying Machine Learning techniques to UAV detection and classification. In Sep 2020, he joined the Microwave Sensing, Signals, and Systems group at Delft University of Technology as a Ph.D. candidate.
