Dyson Professor of Pediatric Oncology at the Dana-Farber Cancer Institute, a Professor of Cell Biology at Harvard Medical School, an Investigator of the Howard Hughes Medical Institute, and the Associate Director for Basic Science at the Dana-Farber/Harvard Cancer Center. He received his undergraduate and medical degrees from the University of Chicago. During medical school, he did research at the Rockefeller University. His postdoctoral fellowship was at the Whitehead Institute/Massachusetts Institute of Technology.<br>\r\n<br>\r\nThe Pellman Lab works on the mechanism of cell division and how certain cell division errors drive rapid genome evolution. His research has contributed to the understanding of cell division, the origin of cell division errors in cancer, how cell division errors drive genetic instability and the mechanisms driving rapid evolution of cancer genomes. Our contributions include (1) the co-discovery of formin-dependent actin nucleation and a mechanism for spindle positioning during asymmetric cell division, (2) discoveries establishing that whole genome duplication can drive tumorigenesis, alter cell physiology, and accelerate evolutionary adaptation, and (3) the discovery of a mechanism explaining chromothripsis, a mutational process that generates rapid karyotype evolution in cancer and congenital disease.</div>\r\n</div>\r\n</div>\r\n</div>\r\n</div>\r\n</div>\r\n</div>\r\n\r\n<div class=\"elementor-element elementor-element-e552a16 elementor-widget elementor-widget-text-editor\">\r\n<div class=\"elementor-widget-container\"> </div>\r\n</div>", "image_description": "", "creation_date": "2026-01-06T16:10:28", "last_modification_date": "2026-01-28T14:34:52", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "SV 1717", "url_place_and_room": "https://plan.epfl.ch/?room==SV%201717", "url_online_room": "https://epfl.zoom.us/j/97039045251?pwd=WDFjUGV3Y1FxeG9rTUIrOGpiUXhLQT09", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "David Pellman, M.D., Margaret M.

We uncovered a new mechanism for coincidence detection in the Drosophila head direction network. To maintain an accurate sense of direction, head direction neurons that signal orientation during navigation must learn to anchor to relevant external sensory cues in novel environments. Yet the synaptic mechanism for this form of unsupervised learning is unknown in any organism. In Drosophila, GABAergic visual inputs converge onto head direction neurons, and these inhibitory synapses change strength with experience to learn the relationship between visual landmarks and head direction. However, how coincident pre- and postsynaptic activity is detected across this inhibitory synapse is not understood. We discovered that neurons which release the monoamine octopamine close a feedback loop that conveys postsynaptic head direction activity onto presynaptic terminals of visual inputs. This octopamine pathway is required for anchoring the head direction network to visual cues. Furthermore, pairing structured activation of octopamine neurons with a visual cue is sufficient to drive rapid plasticity, even without postsynaptic head direction cell activity. Previous work has extensively characterized coincidence detection mechanisms at excitatory synapses; our work defines a novel mechanism for coincidence detection at an inhibitory synapse, in which postsynaptic activity is relayed via a neuromodulatory neuron onto presynaptic terminals.<br>\r\n </p>", "image_description": "", "creation_date": "2026-01-21T16:26:07", "last_modification_date": "2026-02-16T13:34:30", "link_label": "Web Page", "link_url": "https://vcresearch.berkeley.edu/faculty/yvette-fisher", "canceled": "False", "cancel_reason": "", "place_and_room": "SV 1717", "url_place_and_room": "https://plan.epfl.ch/?room==SV%201717", "url_online_room": "https://epfl.zoom.us/j/64813563657", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "Yvette Fisher, UC Berkeley", "organizer": "SV BMI Host: Pavan Ramdya", "contact": "[email protected]", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 3, "fr_label": "Entrée libre", "en_label": "Free" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/119404/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/1/?format=api", "https://memento.epfl.ch/api/v1/mementos/19/?format=api", "https://memento.epfl.ch/api/v1/mementos/9/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api", "https://memento.epfl.ch/api/v1/mementos/88/?format=api" ] } ] }
