Dr. Mark Ward
Medical Scientist, Histopathology


Dr. Mark Ward graduated from Trinity College Dublin in 2012 with a BA (Mod.) in Biochemistry. Following this, he completed a PhD in 2016 in the Department of Pharmacology and Therapeutics in Trinity College Dublin investigating the role of Protein Phosphatase 2A (PP2A) and its endogenous inhibitors in the regulation of matrix metalloproteinases and inflammation in liver cancer.

His current research focuses on the area of "Liquid Biopsy" and the isolation and molecular characterisation of rare circulating tumour cells (CTCs) from breast and ovarian cancer patients. His research interests also include the role platelets and immune cells play in cancer metastasis as well as thrombosis in gynaecological cancers.
