Background

Teresa Puthussery earned her Bachelor of Optometry (O.D.) in 2000 and a Ph.D. in retinal neurobiology in 2005 from The University of Melbourne in Australia. In 2007, she was awarded a CJ Martin Biomedical Research Fellowship from the National Health and Medical Research Council of Australia and a Sir Keith Murdoch Fellowship from the American-Australian Association to pursue postdoctoral training in retinal neurophysiology with Dr. Rowland Taylor at OHSU. In 2013, she was promoted to Research Assistant Professor.

Summary of Current Research

The human retina is remarkable in its ability to extract information about form, color and motion from the visual environment. The Puthussery laboratory is interested in the neural mechanisms and circuitry that underlie these abilities. We are also interested in how these neural mechanisms are perturbed in response to photoreceptor degenerations such as Retinitis Pigmentosa and Age-Related Macular Degeneration. We use a multi-faceted experimental approach, combining immunohistochemistry, single-cell electrophysiology, protein biochemistry and confocal/super-resolution imaging to address our research questions.
