Dr. Stephen Maher

Ussher Assistant Professor (Surgery)


Stephen Maher graduated from RCSI in 2004 with a PhD in Oncology. Having spent 3 years as a visiting fellow at the National Cancer Institute in the USA, in 2007 he returned to Ireland and the Department of Surgery at Trinity College Dublin, St. James's Hospital as a research fellow. In 2010 he established his on group having secured an Irish Cancer Society Fellowship and HRB project grants in 2011 and 2012, all in the area of radiation research. In 2012 Stephen moved to the University of Hull and Hull York Medical School as a senior lecturer where he lead the Cancer Biology and Therapeutics lab. During his time at Hull he gained substantial teaching experience and qualifications, and is a fellow of the UK Higher Education Academy. Subsequently he developed and directed the MSc in Translational Oncology at Hull, as well as undergraduate cancer biology teaching. Additionally, he acquired funding for and established an optical imaging and radiotherapy core at the University of Hull, and aided in establishing the local tumour biobank for translational cancer studies. He has successfully supervised 5 PhD students and has mentored several postdoctoral researchers. He has secured in excess of €1.5m in competitive research funding, and is well published in the field of microRNA, oesophageal cancer and therapeutics research. In 2016 Stephen returned to TCD as the Ussher Assistant Professor in Translational Oncology, Radiation Therapy and Chemotherapy. Here he leads programmes in translational cancer research, focusing on radiotherapy, radiobiology and chemotherapy. He has recently established new hypoxia and radiotherapy research cores at the recently opened Trinity Translational Medicine Institute. Stephen teaches various aspects of cell and cancer biology and therapy across TCD's MSc Translational Oncology and Molecular Medicine.
