Lisa Gunaydin

Lisa Gunaydin is an American neuroscientist and assistant professor at the Weill Institute for Neurosciences at the University of California San Francisco. Gunaydin helped discover optogenetics in the lab of Karl Deisseroth and now uses this technique in combination with neural and behavioral recordings to probe the neural circuits underlying emotional behaviors.

Early life and education Gunaydin completed her undergraduate education at Swarthmore College with a degree in biological sciences. Gunaydin then continued on an academic path by pursuing a Ph.D. at Stanford University. Under the mentorship of Dr. Karl Deisseroth, Gunaydin helped to discover optogenetic technology and apply it to Systems Neuroscience by dissecting neural circuits that drive a variety of complex behaviors in rodents. Optogenetics is a tool used in Systems Neuroscience to activate or inhibit specific neural circuits using transgenically expressed light-activated opsins, originally derived from bacterial opsins. Shining lasers of specific wavelengths causes the channels to open. In 2010, Gunaydin published a first author paper in Nature Neuroscience highlighting her optimization of a new opsin based tool for ultrafast neural circuit control. In this work Gunaydin showed that this novel opsin does not produce unwanted spikes nor persistent depolarizations like what might occur when a cell over-expresses Channelrhodopsin. She and her colleagues also found that the neural projection from the Ventral Tegmental Area (VTA) to the Nucleus Accumbens (NAc) encodes and predicts social behaviors. This was one of the first studies ever to manipulate social neural circuits in real time, using optogenetics, and observe changes in social behavior.

Career and research Gunaydin started her lab at the University of California, San Francisco in 2016 and has since held an assistant professorship in Psychiatry as well as an appointment at the Institute for Neurodegenerative Diseases. In addition, Gunaydin is a member of the UCSF Neuroscience Graduate Program, the Kavli Institute for Fundamental Neuroscience, and in 2017 was named a Chan Zuckerberg Biohub Investigator. Gunaydin's lab aims to investigate the neural circuits underlying motivated behaviors and further understand how they aberrantly function in disease states. Gunaydin's lab is currently focusing on three main projects to address this aim. The first project involves probing the role of cortico-striatal circuitry in modulating anxiety-like behavior as well as elucidating the potential of this circuit as a target of chronic therapeutic stimulation. The other two projects her lab is working on explore the roles of cortical neural subpopulations in obsessive-compulsive disorder behaviors as well as the mechanisms of circuit defects in genetic mouse models for obsessive-compulsive disorder and autism. 2016 UCSF Weill Institute for Neurosciences Innovation Award 2008 Bio-X Bowes Fellow Stanford Adhikari A, Lerner TN, Finkelstein J, Pak S, Jennings JH, Davidson TJ, Ferenczi E, Gunaydin LA, Mirzabekov JJ, Ye L, Kim SY, Lei A, Deisseroth K (2015).
