Professor Tim Palmer

BSc(Hons) PhD FHEA

Chair in Cardiovascular Biology

Role at Hull York Medical School

Tim is the Director of the Centre for Atherothrombosis and Metabolic Disease.

Biography

Tim obtained an Honours degree in Biochemistry at the University of Manchester and a PhD in Molecular Pharmacology at the University of Glasgow. He carried out postdoctoral training as an American Heart Association Research Fellow in the Cardiology Division at Duke University Medical Centre, North Carolina, USA.

He returned to the UK in 1997 as Lecturer in Biochemistry at the University of Glasgow and developed an externally funded research programme focusing on cardiovascular cell signalling and disease.

From 2015 he was Professor of Pharmacology and Head of Pharmacology and Experimental Therapeutics at the School of Pharmacy and Medical Sciences at the University of Bradford before being recruited to a Chair in Cardiovascular Biology at Hull York Medical School in 2018.

Research

Professor Palmer’s interests are identifying the molecular mechanisms responsible for cardiovascular disease. Localised inflammation of branch points within large blood vessels is a pivotal event in the development of atherosclerotic plaque responsible for hear attack and stroke. Inflammation is driven by long-term exposure to chemical signals termed "cytokines" which trigger multiple pathways that ultimately lead to the defective vascular cell function responsible for cardiovascular disease. These processes are also responsible for the failure of bypass and stenting procedures used for acute treatment of patients who have suffered a heart attack.

Current projects

  • Inhibition of pro-inflammatory JAK-STAT signalling by AMP-activated protein kinase
  • Manipulation of suppressor of cytokine signalling 3 (SOCS3) stability and function to inhibit vascular inflammation and re-modelling
  • Exploiting novel protein-protein interactions as targets for new anti-inflammatory JAK-STAT signalling inhibitors
