My long-term research goal is to elucidate the cells and signals in the kidney contributing to renal fibrosis. Specifically, I am interested in kidney pericyte biology and its role in kidney homeostasis and injury. I have extensive training in kidney developmental biology, mouse models for human diseases, molecular biology, molecular genetics and veterinary medicine. I completed my PhD in mouse genetics from LMU Munich Germany. I did my postdoctoral training in Dr. Weining Lu’s lab at the Renal Section, Boston University Medical Campus. Currently I am involved in different interdisciplinary research projects, which include: (1) Role of Slit-Robo signaling in kidney development and podocyte biology and injury and (2) Role of transcription factor ZEB2 in kidney development and disease. In addition, I am also actively participating in mentoring and training of Boston University graduate and undergraduate students.
