Postdoctoral Associate
Yiqin Wang
Yiqin did his undergraduate studies in Biology and received training in Bioinformatics in Shanghai, China. He completed his PhD in Molecular Nutrition at Cornell University in late 2019 with dissertation research focused on the human mitochondrial genome and its roles in development and aging. After graduation, he continued as a postdoc at Cornell University. He is currently a member of the FeGenes team, working with Dr. Kimberly O’Brien and Dr. Andrew Clark to understand the differences in iron homeostasis between East Asians and Europeans. He has a broad interest in studying human diseases, particularly identifying maternal, fetal, and placental determinants of child development and diseases across the life course.
