ICaR-VU Principal Investigator Specialization Role of myofilament proteins in striated muscle function Name Coen Ottenheijm, PhD (30-05-1976) Current position Assistent Professor of Physiology Bio sketch Key Publications (5) Prizes, awards, grants The unifying theme of Dr. Ottenheijm’s research concerns the regulatory pathogenic role of myofilament proteins in striated muscle contraction. Dr. Ottenheijm received his doctorate at the dept of Pulmonology at the Radboud University Nijmegen Medical Center in 2006, where he investigated the contribution of myofilament dysfunction to diaphragm weakness in patients with Chronic Obstructive Pulmonary Disease. His PhD research prompted Dr. Ottenheijm to pursue a postdoctoral position in the lab of Dr. Henk Granzier at the University of Arizona (funded by a NWO Rubicon grant), where he focussed on the role of the giant myofilament proteins titin (the largest protein known to date) and nebulin in muscle function in health and disease. Currently, Dr Ottenheijm is working at the dept of Physiology at VUmc (supported by a NWO VENI grant) and is prinicipal investigator in a collaborative EU (FP7) funded study investigating novel transgenic mouse models of nebulin-based nemaline myopathy, and in a Prinses Beatrix Foundation funded study investigating the role of myofilament dysfunction in muscular dystrophies. Furthermore, in collaboration with the depts of Intensive Care Medicine, Surgery and Anesthesiology at VUmc, Dr Ottenheijm’s research group focusses on the pathogenesis of diaphragm weakness in conditions associated with altered diaphragm activity, such as pulmonary hypertension and mechanical ventilation. 1.
