个人简介

I developed an interest in molecular biology and genetics while pursuing my undergraduate degree here at the University of Guelph. During my Ph.D. training at the University of Toronto under the supervision of Dr. Daniel Dumont, my research focused on the understanding of signal transduction pathways required for blood vessel formation. This process, known as angiogenesis, occurs during normal development as well as in diseases such as cancer. My interests in using proteins as building blocks to assemble signalling pathways brought me to the laboratory of Dr. Tony Pawson for my postdoctoral fellowship. There, I studied a unique signalling scaffold in the kidney known as the slit diaphragm, and through a combination of biochemical, cellular and genetic approaches, we were able to demonstrate the importance of several adaptor molecules in kidney development and disease. In the fall of 2006, I joined the faculty of the newly-formed Department of Molecular and Cellular Biology. My research continues to investigate the molecular basis of signal transduction, with an emphasis on understanding aspects of embryonic development, kidney function, blood vessel formation and nervous system patterning.

研究领域

Research in our laboratory is focused on defining eukaryotic signal transduction pathways, and investigating how mutations in components of these pathways can contribute to human disease. Signal transduction is a central process in multicellular organisms that allows for the exchange of informational cues between and within cells. These cues are interpreted by organized networks of protein interactions inside the cell which regulate complex biochemical events, ultimately converting them into biological responses such as growth, migration, differentiation and survival. Cells have evolved a tremendous ability to selectively activate specific downstream pathways, through formation of distinct protein complexes. Understanding the molecular basis of these interactions is therefore a significant challenge in biology, and it is of key importance in defining how certain mutations can lead to pathological conditions such as kidney disease and cancer. To address these questions, our research team utilizes an interdisciplinary approach, which includes modern mouse genetic tools, cell culture models, high-resolution microscopy, large-scale profiling techniques and clinical specimens. Current areas of research include: Signalling pathways in kidney podocytes. Cell migration pathways in cardiovascular development. Characterization of a novel neuronal adaptor protein, ShcD.
