The Gatsby Program in Theoretical Neuroscience at the Edmond and Lily Safra Center for Brain Sciences (ELSC) is inviting applications for postdoctoral fellowships from students who are finishing, or have recently finished, their Ph.D. studies in mathematics, physics, computer science, computational neuroscience, or related fields. Preference will be given to postdocs who perform collaborative research mentored jointly by theorists and experimentalists. A priority area for the Program is sponsoring activities that strengthen the ties between this Program and the two partner centers: the Gatsby Unit for Computational Neuroscience (UCL, London) and the Center for Theoretical Neuroscience (Columbia University, NY). These activities include joint meetings, exchange of students, postdocs and faculty, and collaborative research. Research at ELSC offers a vibrant scientific environment and excellent opportunities for interaction with researchers interested in systems and computational neuroscience.

Fellows are admitted to the Program based on their credentials and are free to choose their research agenda and their host lab in the course of their first semester in residence. In addition to upgraded salaries and housing support, Fellows receive modest research funds aimed primarily for travel to other labs or conferences. Fellows are expected to actively participate in initiatives that strengthen Tri-Center interactions. *Applications* Candidates for postdoctoral fellowships and applicants for the Fellows Program are invited to send their CV and research statement, and to arrange for three letters of reference to be sent to Ms. Irit Dagan: irit.dagan1@mail.huji.ac.il. *Theoretical Neuroscience at the Hebrew University * Haim Sompolinsky, Program Director (Physics, ELSC) Yoram Burak (Physics, ELSC) Amir Globerson (Computer Science) Yonatan Loewenstein (Cognition, Neurobiology, ELSC) Idan Segev (Neurobiology, ELSC) Naftali Tishby (Computer Science, ELSC) Daphna Weinshall (Computer Science) Yair Weiss (Computer Science, ELSC)
