Personal profile


Dr Barry O’Hagan is a Scientific Officer in Bioimaging in the School of Biomedical Sciences at Ulster University. After graduating with a BSc Hons (2.1) in Biological Sciences he completed a MRes with distinction in studies allied to medicine at Ulster University. He commenced his PhD studies in the School of Biomedical Sciences at Ulster University. completing his thesis entitled ‘A stereological Investigation of Angiogenesis in Human Colorectal Tumours’ in 2001.

Dr O’Hagan has more than 20 years research experience in the areas of microscopy, bioimaging, histology and immunofluorescence.

He has worked extensively with Industry including a number of global leaders in the pharmaceuticals and agri-food sectors, and has established a strong track record in successfully delivering bespoke imaging solutions within industry relevant time-frames.

Dr O’Hagan’s expertise in the fields of microscopy and bioimaging has resulted in competitively awarded research funding of over £600K (e.g, from Innovate UK, DAFM/DAERA,)

He has published over 14 research articles in high impact peer-reviewed journals, with over 100 citations of his work to date.

Dr O’Hagan currently manages and maintains the Bioimaging Core Facility Unit, which houses in excess of £4M of state of the art microscopical equipment located within Ulster’s BMSRI.and leads research at Ulster into hydration of milk powder products.
