Biography

Alejandro Pascual Laguna received the B.Sc. degree in telecommunications engineering from ICAI School of Engineering, Universidad Pontificia Comillas, Madrid (Spain), in 2014. During the last year of his bachelor’s degree studies, he spent a year at Chalmers University of Technology, Gothenburg (Sweden). He received the M.Sc. degree (cum laude) in Electrical Engineering and the Ph.D. degree from the Delft University of Technology (TUDelft) in 2016 and 2022, respectively. Since December 2016 he has been with SRON Netherlands Institute for Space Research. He is currently a postdoc with SRON and TUDelft.

<br>

His research interests include on-chip solutions for efficient broadband sub-mm wave imaging spectrometers based on Kinetic Inductance Detectors. During his Ph.D., he coauthored 5 journal publications and 18 contributions at various international conferences, and he co-supervised one M.Sc. student in the THz Sensing group.
