How Does Blue Light Intercept Cellular Life?

Dr Ajith Karunarathne, University of Toledo

Presentation Abstract

Blue light is an integral component of natural as well as human-made light. Several decades worth literature indicates blue light-induced cytotoxic (i. e. vision and melanoma) as well as behavioral (insomnia) effects in humans. We show molecular level interactions between blue light and living cells, providing targets for intervention and treatment of photodamage.

Dr. Ajith Karunarathne is an associate professor at the Department of Chemistry and Biochemistry at the University of Toledo. He is also a cellular photochemist with nearly 15 years of experience.
He is also an expert in subcellular optogenetics as well as phototoxicity. His research on phototoxicity of blue light and retinal became a top 100 attention-grabbing publication in 2018. Dr. Karunarathne has a Ph.D. in bioanalytical chemistry from Michigan State University and postdoctoral training in signal transduction from Washington University School of Medicine.

He is the author/co-author of numerous publications, including peer-reviewed manuscripts and book chapters. Among his current research, vision-related health effects of blue light and intricate regulation of cellular signaling networks, as well as their underlying molecular pharmacology, are prominent.
