Yesl Jun, Ph.D.

Postdoctoral Fellow

I received my M.S. and Ph.D. in Biomedical engineering from Korea University, South Korea. Here, I worked in the laboratories of Prof. Sang-Hoon Lee and Prof. Seok Chung. My research focused on engineering three-dimensional (3D) microtissues with microfabrication technologies for application in tissue engineering and regenerative medicine. My Ph.D. research was to develop pancreatic islet microtissues with improved survival and insulin secretory function by controlling pancreatic microenvironments using 3D microfluidic cultural systems. Given my background and experience in microfluidics, my research in the Sander laboratory is to create in vitro 3D biomimetic platforms for better understanding of human pancreatic beta cell differentiation. I am interested in controlling islet cell microenvironmental cues in 3D culture, and studying cell-extracellular matrix interactions, vascularization, and the crosstalk between related organs with ultimate goals of in vitro disease modeling of type 1 and 2 diabetes.
