Jesper Sjöström is Associate Professor in neuroscience at McGill University, where his team explores plasticity in the brain using 2- photon imaging, quadruple patching, optogenetics, and computer modelling. After an MSc in molecular biotechnology at Uppsala University in 1996, he obtained a PhD in neuroscience at Brandeis University in 2003. Following four years of postdoctoral studies at University College London, he remained as an MRC CDF awardee running his own lab. After arriving at McGill in 2011, he received the CIHR New Investigator and the FRQS Chercheur-Boursier awards. His research has unveiled plasticity learning rules, neocortical connectivity patterns, and unorthodox forms of NMDA receptor signaling. He is Chief Editor of Frontiers in Synaptic Neuroscience.
