Dr. Jorquera is natural from the Copiapo Valley, located in the Atacama region of the North of Chile. He graduated as a Biochemist from the Catholic University of Valparaiso in 1999, received his Ph.D. in Cellular and Molecular Biology from the Universidad Austral de Chile in 2008, and his postdoctoral training at the Massachusetts Institute of Technology (MIT) between 2008 to 2011. In 2012 he started a lab in Puerto Rico working in the molecular regulation of vesicle fusion and synaptic plasticity. He has been back in Chile since 2019 at the ICB, UNAB. He awards MECESUP, Conicyt, IBRO, and PEW fellowships. As faculty, grants the U54 and the RO1 mechanism from the National Institute of Neurological Disorders and Stroke from the National Institute of Held. He has been a faculty at the Medical Schools in the US since 2011 and in Chile since 2012. He mentored dozens of graduate students, a few postdocs, and junior faculties funded by a Specialized Neuroscience Research Program of NIH-NINDS #U54NS083924. Also, he established an independent and competitive research Laboratory funded by NIH-NINDS #R01NS108778. In addition, he served at the reviewer panels at the National Science Foundation and as a Latin-American partner at the Center for Brain, Mind + Machines, MIT. He served as a scientific reviewer for journals PloseOne; European Journal of Biophysics; IEEE Transactions on Molecular, Biological, and Multi-Scale Communications; Scientific Report, eNeuro, PNAS, and Journal of Neuroscience.
The focus of the laboratory’s work is to understand how synaptic connections form, how synapses transmit information, and how synapses undergo plastic changes in their structure and function. To complement this basic research in neuroscience, the lab also studies how alterations in neuronal signaling underlie several neurological and myasthenic diseases. The lab combines Behavior, Electrophysiology, Fluorescence Imaging, Electron Microscopy, Molecular Biology, and Protein Biochemistry with Drosophila Genetics to address these questions. The successful applicant will join a dynamic and growing biomedical community with access to a broad range of the latest scientific technologies.
