Biography
Jeong Hun Jo, PhD grew up in Busan, South Korea and received a bachelor’s degree in electronic engineering as summa cum laude from Gyeongsang National University in Jinju, South Korea. He earned a Doctor of Philosophy in 2019 at the School of Interdisciplinary Bioscience and Bioengineering in Pohang University of Science and Technology (POSTECH) in Pohang, South Korea. His doctoral thesis was to investigate an age-dependent increase in glutamate decarboxylase 67 (GAD67) in mouse pancreatic islets. He joined Hughes Lab in 2019 as a Postdoctoral Research Associate right after graduation. After finishing 5-year postdoc, he became a Staff scientist in 2024 and then since July 1st, 2025, he joined new Hughes Lab at Yale as an Associate Research Scientist.

Overview
Primary cilia are antenna-like structures acting as signaling-transducers in cells. Recently, Hughes Lab reported that beta cell primary cilia regulate glucose homeostasis via paracrine signaling and their motility controls insulin secretion in pancreatic islets. His main research interests are how 1) primary cilia mediate key signaling pathways (ex, Wnt, Hedgehog (Hh), Notch, and GPCR signaling etc.) and 2) primary cilia-relayed molecular mechanisms change between heathy and Type 2 Diabetic human pancreatic islets.
