- Profile
-
I am currently a research group leader and lecturer in the Molecular Medicine division, Faculty of Health, at the University of Sheffield.
My academic journey led me to obtain a PhD in Biochemistry and Molecular Biology from University College London (UCL), which I completed in 2009. I then joined Professor Jeremy Saklatvala’s laboratory at the Kennedy Institute of Rheumatology (Imperial College London) as a postdoctoral research fellow, where I developed a keen interest in the molecular mechanisms underlying osteoarthritis.
In 2011, I moved to the University of Oxford as a senior postdoctoral fellow within the Osteoarthritis Centre of Excellence. My research there focused on the cellular events triggered by mechanical tissue injury, leading to the identification of key upstream mechanisms driving tissue damage in osteoarthritis.
In 2018, I was awarded a Career Development Fellowship (CDF) by Versus Arthritis to investigate the ubiquitination machinery and enzymes mediating connective tissue injury, which are critical for the development of disease-modifying therapies for osteoarthritis and other musculoskeletal disorders. This fellowship enabled me to relocate to the University of Sheffield where I established my research group.

Research in my lab uncovers the cellular mechanisms driving chronic inflammation and tissue damage in musculoskeletal diseases, with a particular focus on osteoarthritis. We aim to redefine therapeutic strategies for osteoarthritis by disrupting the vicious cycle of mechanical injury and inflammation.
Our primary focus is on the ubiquitination machinery that mediates inflammatory responses triggered by mechanical stress. By targeting these pathways, we seek to develop disease-modifying therapies for osteoarthritis and related musculoskeletal conditions. Beyond osteoarthritis, our research also explores how the ubiquitin system contributes to mechanoflammation in the contexts of ageing, multimorbidity, and cancer.
To achieve these goals, we employ a range of advanced in vivo and ex vivo models, including murine and zebrafish systems, as well as human and porcine tissues. Our toolkit includes cutting-edge technologies such as advanced transgenesis, in vivo live imaging with light-sheet and confocal microscopy, functional genomics using CRISPR/Cas9-based loss-of-function and gain-of-function screens, mass spectrometry, and diverse biochemical approaches. These methodologies allow us to dissect the function and regulation of the ubiquitin system in both in vivo and in vitro settings.
