A full time Postdoctoral position is available in the laboratory of Prof. Richard Lang at the Science of Light (SOL) Center and the Division of Pediatric Ophthalmology, Cincinnati Children’s Hospital Medical Center in the United States. We are seeking highly motivated applicants to investigate light receptors, metabolic regulation and nervous system development. The ideal candidate is expected to work both independently and as part of an interactive team. Full-time positions are available for 2 years (with the possibility of a renewal for two years, pending satisfactory performance). Starting date: As soon as possible.
Project description: The Lang lab is currently working to understand how the non-visual opsins OPN3 (encephalopsin), OPN4 (melanopsin) and OPN5 (neuropsin) regulate light-dependent development and homeostasis. We have shown that both melanopsin/OPN4 ( Rao et al., Nature, 2013 ) and neuropsin/OPN5 ( Nguyen et al., Nature Cell Biology, 2019 ) provide timing cues for vascular development in the eye and regulate refractive ( Linne et al., Mol Vis, 2023 , Jiang et al., PNAS, 2021 ) and photoreceptor ( D’Souza et al., Dev Cell, 2024 ) development. We have also shown that OPN3 in adipocytes and in the paraventricular nucleus ( Nayak et al., Cell Reports, 2020 ; Haddad et al., PNAS, 2025 ) as well as OPN5 in hypothalamic neurons ( Zhang et al., 2020 ) regulate metabolism and energy homeostasis. This work describes a new light-dependent physiological axis.
