Job Title:

Lecturer in Clinical Pharmacology/Therapeutics

Responsibilities:

Module convenor for PM2C2, Part 2 Academic Year Tutor

Areas of Interest:

Numerous serine proteinases including trypsin and neutrophil elastase are released during pathological and inflammatory conditions (e.g., cancer, arthritis, asthma and neurodegenerative diseases) or after tissue injury and ischemia (e.g., myocardial infarction, stroke and intestinal ischemia). By acting on different cell types, proteinases activate cell-surface receptor to activate intracellular signaling cascades that promote and control numerous cellular functions. Dysregulation of these signaling mechanisms may result in excessive neuronal excitation, neurotoxicity, perception of pain, neurogenic inflammation, neurodegeneration and reparative neovascularisation.

My research aim is to elucidate the molecular mechanisms regulating serine proteinase -induced cellular responses. In particular, my research aims to clarify how proteinases, by cross talking with ion channels such as TRPV1 and TRPV4, affect the functions of neuronal, glial and endothelial cells.

Understanding the molecular mechanisms underlying serine proteinase -mediated processes will help to identify new molecular targets for potential therapeutic intervention.

This might aid the development of new drugs aimed at preventing the advancement of pathological conditions that lead to illness including Alzheimer's and Parkinson's diseases  or at treating inflammations and rescue damaged organs.

Current Research:

• Protease activated receptors signalling in neurons, glial and endothelial cells
• Molecular mechanisms that control neuronal and non-neuronal cells damage and survival
• Stem cells and neurodegeneration
