Research Overview

Primary cilia, Tissue biomechanics, Cancer, Cartilage, Inflammation, organ-on-a-chip, Bone, Cardiovascular diseases


My research concerns the area of mechanobiology or how living cells and tissues ‘sense and respond’ to mechanical forces at a biological level and also in terms of their biomechanical properties. This is essential for the health and functionality of many tissues and therefore has potential application in various medical therapies from tissue engineering and regenerative medicine to pharmaceuticals. Studies are examining the role of mechanobiology in a variety of conditions including ageing, cancer, tendonopathy, inflammation and arthritis.  

My current research splits into the following areas of mechanobiology:

Primary Cilia Structure and Function

A particular focus of my research involves the role of primary cilia in mechanobiology. These fascinating cellular structures have been largely ignored, but have recently been shown to be involved in mechanosignalling although the mechanisms are not yet clear. Furthermore mechanical forces regulate the expression of cilia which in turn modulates other signalling pathways. My group are examining the relationship between cilia structure and function and how this is influenced by physicochemical stimuli. Our studies have shown how regulation of cilia length controls hedgehog signalling (Thompson et al. 2014; 2015; Prodromou et al. 2012), wnt signalling (McMurray et al. 2014), and growth factor signalling (Dalbay et al. 2015). Our group published the first paper showing that primary cilia are required for cartilage mechanotransduction and upregulation of proteoglycan synthesis (Wann et al. 2012a). We have also shown, for the first time, that primary cilia are involved in inflammatory signalling in response to cytokines such as interleukin-1 (Wann et al. 2012b; 2013; 2014).

Through understanding these fundamental behaviours and the effect of physicochemical stimuli we hope to have future impact in the development of 'ciliotherapies' for treatment of disease and injury. 

I helped set up the UK Cilia Network bringing together researchers with a common interest in cilia. 

Organ-on-a-Chip in vitro models

A key priority is the development of 'organ-on-a-chip' in vitro models which incorporate the appropriate biomechanical stimuli to accurately replicate in vivo conditions within the human body. 

I am co-director of the UK organ-on-a-chip technologies network led by Prof Hazel Screen and funded by MRC, EPSRC and BBSRC. I am Director of the Queen Mary & Emulate Organs-on-chips Centre the first of its kind in the UK providing access to state-of-the-art organ-chip technology and validated organ-chip models. WIth Prof Hazel Screen we have set up the cross-faculty Centre for Predictive in vitro Models and the new QM Centre for Doctoral Training in Predictive Models for Medical Innovation and Research (PreMMIR).

My research activity is focussed on the development of organ-on-a-chip in vitro models with a particular focus on incorporation of appropriate biomechanical stimuli to replicate the physiological and pathological environment. Research projects funded by MRC, EPSRC, EU and CRUK are examining the development of organ-chips for study of musculoskeletal disease and various cancers (see fundng for details)

I am actively seeking collaboration with academic and industry partners as well as incoming PhD students and research fellows through schemes such as the Marie Sklowdoska-Curie Fellowships.
