Research

The use of radiotracers to non-invasively image living systems using Positron Emission Tomography (PET) is a powerful technique to investigate neurological disease. Within the MICL research is broadly directed into 3 areas:

 

Neurodegenerative Disease

The sensitivity and selectivity of radiotracers gives PET the ability for unique insights into neurodegenerative disorders and traumatic brain injury (TBI). We currently have interest in developing radiotracers to image Alzheimer's disease, Parkinson's disease, and TBI induced Epilepsy.

Neuropsychiatric Disease

The sensitivity and selectivity of  PET the ability to develop functional radiotracers to gather unique insights into neuropsychiatric disorders at the molecular level. We currently have interest in developing radiotracers to conduct pre-clinical imaging of OCD, ADHD, drug addiction and schizophrenia.

Radiochemical Methodology

Synthesis of molecules containing short lived radionuclides is often challenging. As a result the development of new radiochemical methodology to install new radioactive functional groups or higher yielding more tolerant radiochemical reactions is of significant interest.
