Bernardo L. Sabatini

Sabatini received his S.B. in biomedical engineering from Harvard College. He later completed the MD/PhD at Harvard Medical School, obtaining his MD through the Health Science and Technology program co-administered by Harvard and the Massachusetts Institute of Technology and his PhD through the Program in Neurobiology at Harvard. After graduation he began as a postdoctoral fellow with Karel Svoboda, then at Cold Spring Harbor Laboratory. In 2001, Sabatini established his own research group in the Department of Neurobiology at Harvard Medical School. He was named a Howard Hughes Medical Institute Investigator in 2008. and the National Academy of Sciences in 2019. ==Research==

Sabatini's research group studies the biophysics of synapses and synaptic plasticity, and the connection between properties of neurons and their networks to animal behavior and disease. The group has developed methods and technologies to support this work and is well known in particular for advances in two-photon microscopy and more recently, super-resolution microscopy. He is one of six co-founders of the Italy-based biotechnology company OptogeniX, which sells equipment for optogenetics studies. Synapses and dendritic signaling Sabatini's work has contributed to understanding the biochemical and electrical properties of dendritic spines, specialized structures that compartmentalize synaptic signaling. His studies demonstrated mechanisms regulating calcium signaling and molecular diffusion within dendritic spines. These findings helped clarify how individual synapses integrate signals during synaptic plasticity. These studies have explored how synaptic signaling and neuronal network activity contribute to behavior and motor control. == Selected Publications ==
