Curriculum vitae

1996: Diploma in Biology at the Albert Ludwigs Universität, Freiburg

1992-93: Year abroad at the University of Edinburgh, Scotland

1997-99: PhD thesis in Alexander Borst's lab at the Friedrich-Miescher-Laboratory in Tübingen (Max Planck Society). I investigated calcium signaling in visual interneurons of the blowfly and in isolated neurons of the locust. During my PhD, I was a member of the "Graduiertenkolleg Neurobiologie Tübingen".

2000-03: Postdoc in Karel Svoboda's lab in Cold Spring Harbor, NY. To investigate release probabilities and response amplitudes at single synapses, I measured postsynaptic calcium transients in single spines by two-photon laser-scanning microscopy. Experience the beautiful spatial and temporal resolution of this technique in a movie of postsynaptic calcium signals. This project was supported by the Swartz Foundation. Historic pictures of the Cold Spring Harbor Climbing Club have been archived by Emiliano Rial-Verde.

2003-11: Research group leader at the Friedrich Miescher Institute in Basel, part of the Novartis Research Foundation. To stimulate individual cells in intact tissue, we started using variants of the light-gated ion channel Channelrhodopsin-2 as well as two-photon glutamate uncaging. With these techniques, we discovered that mGluR-dependent depression is restricted to spine synapses containing a 'spine apparatus'. We also found evidence for very strong depolarization of individual spines during synaptic transmission, an indication of electrical isolation of dendritic spines from their parent dendrites. Big thanks to our longtime collaborators Benny Bettler in Basel and Peter Hegemann in Berlin ! Historic lab pictures can be found here, as well as our first realistic model of consciousness.

since 2005: Faculty of the summer course 'Neurobiology' at the MBL in Woods Hole, MA. Here is an animation that Mark Terasaki developed during the 2008 course to demonstrate how scattering of light in tissue can help you to detect photons. I highly recommend the Woods Hole courses! (fried squid - mmm!)


Since October 2011: Professor for Neuroscience at the University of Hamburg at the Center for Molecular Neurobiology Hamburg (ZMNH). Our new lab, which we call the Institute for Synaptic Physiology, is picking up speed!
