Biography

Sjoerd Bosma received the M.Sc. degrees (cum laude) and the Ph.D. degree (cum laude) in electrical engineering in 2017 and 2023, respectively, from the Delft University of Technology (TU Delft), Delft, The Netherlands. 

During his Ph.D., his research focuses on the analysis, design and demonstration of millimeter and submillimeter-wave leaky-wave lens antenna arrays. In 2018-2019, he spent five months at the Submillimeter-Wave Advanced Technology (SWAT) group at NASA/JPL, as a Visiting Student Researcher. The work for his Ph.D. thesis has resulted in eight journal publications and 24 papers in conference proceedings. 

Sioerd is currently RF/Wireless Development Engineer at NXP Semiconductors, Eindhoven, The Netherlands.
