Professional Interests
I am interested in the establishment and maintenance of cellular identity. These processes depend on correctly controlled access to biologic information by creating, remodeling or removing genetic and epigenetic barriers that modulate access to the information stored in the DNA sequence. A deep understanding of how these mechanisms regulate development and terminal differentiation are essential in order to understand diseases such as cancer and natural processes such as aging and for the development of treatments for many of the health issues impacting modern society.
We are using the recent development of in vitro cellular reprogramming (iPSC) and differentiation of these cells into hepatocytes (iHeps) to facilitate liver repair via cellular transplantation. Both of these processes are heavily dependent on modulation of genetic and epigenetic mechanisms that control access to information in the DNA sequence. Our three main focuses are 1. The development of a clinically safe and feasible reprogramming system suitable for large-scale clinical applications. 2. The development of a clinically safe and feasible hepatocyte differentiation system suitable for large-scale clinical applications. 3. The development of a clinically relevant cellular transplantation regimen that allows efficient re-population of a host liver using targeted radiation therapy.
A practical system of quickly and safely generating patient derived iPSCs in the clinic coupled with in vitro differentiation of these cells into specific cells and tissues is needed in order for this to become a real treatment option and not only a research tool.
