Research Programs




Casper Beijst is a medical physicist and scientist at the department of radiotherapy of the UMC Utrecht. His research focuses on motion correction for pediatrics and radiotherapy.

He is the leader of the molecular and motion reconstruction group and was recently awarded with an NWO OTP grant and a KWF PPS grant for 4 PhD students, a postdoc and a research enigneer. Several MSc students are trained in the group.

He has an official double registration as a medical physicist both in the field of radiotherapy and radiology/nuclear medicine. The crossover in expertise allows him to bridge the gap between radiology and radiotherapy with the aim of improving imaging for therapy guidance.
