Dr Tim Wells is a metabolic neuroendocrinologist in the School of Biosciences at Cardiff University, working at the interface between nutrition, hormones, neuroscience, physiology and connective tissue biology.
Tim studied Physiology at Leeds University, acquiring an interest in both neuroscience and hormones. This paved the way for his PhD in the Department of Physiology at University College London in which he studied the osmotic regulation of vasopressin secretion. After a couple of short post-doctoral positions at St Thomas’ Hospital and Manchester University, Tim leapt across the divide into the anterior pituitary, working in the laboratory of Prof Iain Robinson at the National Institute for Medical research on generating and analysing new rodent models of altered growth hormone activity.
Since joining Cardiff University, Tim has focused on generating novel rat models of altered neuroendocrine function, and on the activity of the gastric hormone, ghrelin. Given that the biological activity of ghrelin is determined by the pattern in which the body is exposed to it, Tim has recently started using an automated feeding station to determine the complex physiological consequences of manipulating the pattern of feeding – asking the question whether grazing is better than “three meals a day”?
Tim has now authored >50 publications in the primary scientific literature, his most cited publication being the first demonstration of an action of unacylated ghrelin in vivo (cited >450 times).
