Sumathi Sekaran

Sumathi Sekaran serves as Senior Research Scientist at the University of Oxford and Deputy Course Director of the Oxford Online Programme in Sleep Medicine, while holding a Fellowship in Biomedical Sciences at St Catherine's College where she teaches undergraduate students.

Her educational background includes:

• PhD from Imperial College London (2001)

Dr. Sekaran's research pioneers visual neuroscience with seminal contributions to understanding melanopsin-expressing ganglion cell photoreceptors that regulate circadian rhythms and sleep-wake cycles. Her work spans retinal degeneration mechanisms, photoreceptor transplantation for vision restoration, and non-image-forming visual pathways. Current investigations focus on translating basic discoveries in circadian biology into clinical sleep medicine applications through innovative educational programs.

Analysis of her publication timeline reveals evolving expertise from foundational retinal photoreceptor characterization (2003-2005) to contemporary gene therapy applications (2019), consistently bridging molecular neuroscience with clinical sleep disorders research.

As educational leader for Oxford's online Sleep Medicine program since 2016, she champions digital pedagogy and inclusive practices while directing course development. Her academic service integrates research leadership with curriculum innovation in postgraduate medical education.

Dr. Sekaran leads the Experimental and Clinical Sleep Medicine research group, fostering interdisciplinary collaboration between Oxford's neuroscience departments and collegiate teaching systems to advance both research and education in sleep science.
