Three Counties Medical School

MBChB

Contact Details

Elizabeth is exited to become a lecturer here at the 桔子短视频 in the TCMS. She is a biochemist by training and looks forward to applying her cell biology understanding of disease to a more wholistic understanding of medicine through teaching in the TCMS.

Prior to joining Worcester, Elizabeth worked within medical schools on the research side, specifically on basic cellular processes in mammalian and fungal cells. Her MSc research was on DNA damage and the DNA damage repair and response pathways. Her PhD research focused on metabolic regulation in the cell. Specifically, how the NuA4 (AKA Tip60) complex, a lysine acetyltransferase, plays an important role in the regulation of mitochondrial structure and function, glycogen storage, and lipid composition.

Qualifications

PhD in Biochemistry University of Ottawa
MSc in Biochemistry University of Western Ontario
BEd Queen’s University Canada
BSc Trent University

Research Interests

Biochemistry, understanding cell signalling
Regulation of cellular processes.
