Molecular Organization of the Photoreceptor Synapses
April 9, 2026 — 12:00 pm to 1:00 pm ET
Kirill A. Martemyanov, PhD
Professor And Chair, Department Of Neuroscience
University of Florida Health
Dr. Martemyanov and his laboratory study the fundamental principles that regulate signaling via G protein coupled receptors (GPCR). GPCRs mediate a vast variety of critical biological processes ranging from proliferation and motility to cellular reception and excitability. GPCR signaling pathways are of particular importance for the nervous system function where they control many fundamental processes including excitability, differentiation, sensory perception and synaptic transmission.
Cellular and Molecular Dynamics Shaping the Vertebrate Eye
March 26, 2026 — 12:00 pm to 1:00 pm ET
Kristen Kwan, PhD
Professor
University of Utah
Dr. Kristen Kwan and her laboratory study the cellular and molecular mechanisms underlying tissue morphogenesis: the process by which a group of cells achieves its proper cellular organization and shape. Using the vertebrate eye as a model, they want to understand how the cells that comprise the vertebrate optic cup – neural retina, retinal pigmented epithelium, and lens – form the stereotyped structure that is critical for visual function.
Recruitment of Primate Oculomotor Networks for Abstract Cognition
March 5, 2026 — 12:00 pm to 1:00 pm ET
David Freedman, PhD
Professor
University of Chicago
Dr. David Freedman and his laboratory use advanced neurophysiological and behavioral techniques, in parallel with machine learning approaches for studying cognitive computations in artificial neural networks. Together, their work is providing insights into the brain mechanisms of visual learning, recognition and decision making.
Aging RPE and Plasma Membrane Integrity
February 12, 2026 — 12:00 pm to 1:00 pm ET
Dorota Skowronska-Krawczyk, PhD
Associate Professor
School of Medicine, University of California
Dr. Dorota Skowronska-Krawczyk's lab focuses on understanding the molecular mechanism of aging in the age-related eye and brain conditions. They study processes regulating gene expression in age-related diseases, with emphasis on how aging affects cellular, metabolic, and transcriptional programs. Mechanism of senescence and polyunsaturated fatty acids metabolism are the two major areas of interest in the lab.
Sayer Vision Research Lecture & Award: "Targeting Cellular Senescence in Retinal Vascular Disease"
February 10, 2026 — 3:00 pm to 4:30 pm ET
Przemyslaw (Mike) Sapieha, Ph.D.
Professor
University of Montreal, Montreal
Dr. Sapieha is the University of Montreal Endowed Chair in Translational Vision Research, Canada Research Chair in retinal cell biology and full professor in the Departments of Ophthalmology and Biochemistry. His team identified mechanisms implicating semaphorins, deregulation of neuronal metabolism, innate immune memory and cellular senescence in retinal vascular diseases such as diabetic retinopathy and age-related macular degeneration (AMD).
