Biographical Sketch

Charles Helsper was born on the 9th of March 1980 in Pullman Washington (USA). After graduating from the Atheneum at the ‘Bisschop Bekkers College’ in Eindhoven and the first year of Health Sciences at Maastricht University, he studied Medicine at Utrecht University. During these studies he developed an interest for both the practice and research of primary care and prevention.

To put this interest into practice he combined the GP-specialty training with a PhD programme at the Julius Center for Health Sciences and Primary Care at the Utrecht Medical Center. His PhD programme addressed identification strategies for hepatitis C infection from a primary care point of view.

During this combined programme he also successfully finished a Prestige Master in Epidemiology, worked as a lecturer at the GP specialty training, at Utrecht University and as an invited lecturer at the Centre for Research in Evidence-Based Practice at Bond University (Australia).

Currently he is working as a senior researcher at the Julius Center for Health Sciences and Primary Care, with a focus on cancer in primary care. In addition, he works at the Utrecht GP specialty training and Utrecht University, with a main focus on improving the use and education of scientific evidence in primary care practice.




Side Activities

THINC.  Advisor - The Health Care Innovation Centre

THINC (The Healthcare Innovation Center)., as part of the UMC Utrecht Julius Center, contributes to the continuous development of scientific knowledge at the service of healthcare innovation. We combine state of the art scientific expertise in the fields of HTA (Health Technology Assessment), clinical epidemiology, public health, ethics, primary care and implementation. From the early innovation stages THINC can inform innovators on the anticipated working mechanism (causal pathways), usability, validity and (cost-effectiveness). THINC aims at a broad range of healthcare innovations including medical technology, devices, mHealth, eHealth and care pathways.
