Stefan J. Wijnholds was born in Groningen, The Netherlands, in 1978. In 2003, he received the M.Eng. degree in Applied Physics (cum laude) for a study on a measurement technique to evaluate the optics of the Heterodyne Instrument for Far Infrared (HIFI) of the Herschel Space Observatory at sub-millimeter wavelengths with the Space Research Organization of the Netherlands (SRON) in Groningen. In the same year, he also received the M.Sc. degree in Astronomy (cum laude) for a study on the integration and evaluation of a phased array antenna system for radio astronomy with the Netherlands Institute for Radio Astronomy (ASTRON) in Dwingeloo, The Netherlands.
After his graduation, he joined to R&D department of ASTRON, where he works with the system design and integration group on the development of the next generation of radio telescopes. He has been involved in integration and testing of all LOFAR (prototype) stations deployed since 2003 with a focus on station calibration and system characterization. Since 2006, he has also been affiliated with the Delft University of Technology in Delft, The Netherlands, where he received the Ph.D. degree (cum laude) in 2010 after defending his thesis on "Fish-Eye Observing with Phased Array Radio Telescopes".
His research lie in the area of array signal processing, specifically calibration and imaging.
