Raphael Courjaret   Assistant Professor of Research in Physiology and Biophysics

Dr. Courjaret received his Ph.D. in Neuroscience from the University of Angers, France, where he studied the intracellular regulation of nicotinic receptors in neurons. Subsequently, he conducted postdoctoral research training in France in the laboratory of Dr. Bernard Poulain (CNRS UPR2356, Strasbourg, France) and with Professor Joachim Deitmer in the Laboratory of Zoology (Kaiserlsautern, Germany).

Dr. Courjaret joined Dr. Khaled Machaca’s Lab at WCM-Q in 2010 as a Postdoctoral Associate in Physiology and Biophysics to work on the intracellular signaling processes involved in the development of Xenopus oocytes. Since 2013, as a Research Associate in Physiology and Biophysics, his research has focused on intracellular calcium signaling in Xenopus oocytes and mammalian cells. He is particularly interested in understanding how cells can deliver precisely intracellular Ca2+ ions to specific targets using electrophysiology and various imaging techniques such as live confocal and TIRF.

Dr. Courjaret has also participated in teaching our medical students as a facilitator for journal club for Brain and Mind (BAM) and in small-group discussions for Essential Principles of Medicine (EPOM).

research overview

  • I focus on intracellular calcium signalling mechanisms in the Xenopus oocyte and in mammalian cells. I particularly work on identifying in cells how calcium ions can reach a specific target without affecting other intracellular calcium sensors. In that purpose I combine various imaging techniques to monitor calcium in different cell compartments withe electrophysiology (TEVC and patch-clamp).
