Tim Roberts, Emeritus Professor, School of Enivronmental and Life Sciences, University of Newcastle, is acknowledged as an expert in the area of chronic pain, fatigue and autism. The premise behind his approach is that all disease has a molecular basis. His research consistently finds that there is a distinct profile obtained that correlates with a particular symptom set. The data are used to propose to the clinician treatment options that often are aimed at normalising the metabolism of the individual.
