Biography

Dr. Niall Colgan is a lecturer in medical physics and a clinical medical physicist.  His work has been applied in diagnostic imaging projects related to dementia, acquired brain injury, psychosis, neurological disorder, oncology, musculoskeletal and cardiac disease.  His primary research focus is biophysics and diagnostic imaging, particularly MR metabolite imaging and diffusion MRI however he also has active research programs in ionizing imaging, computational modeling/simulation, Microscopy, data mining, clinical instrumentation and tissue mechanics. He has led research teams  in the area of preclinical imaging bio-markers  and preclinical drug trials and has directed and established clinical imaging research  facilities utilized in clinical research and trials. A particular interest is the development of imaging methods that will open up new possibilities for the diagnosis and evaluation of therapeutic efficacy.
