Funded PhD: Optimising host response biology to advance wound dressing efficacy

Project in brief

Chronic, non-healing wounds affect 22 million patients annually. Whilst advances have been made in antimicrobial and moisture protecting dressings there remaining significant challenges in providing dressings which can resolve chronic inflammation within the non-healing wound bed. One of the most important considerations is optimisation of the interface between the dressing and the wound bed in order to moderate hyper-inflammation and promote wound healing. This can be done through biomimicry in which host response biology is taken into account to improve protein interactions, prevent biofouling and other negative triggers which repress wound resolution. In this project you will develop methods to profile the wound bed environment for optimization of wound resolution processes using surface modified dressings. You will work in an interdisciplinary research environment at the interface between biomaterials, tissue engineering and bioengineering.

I supervise research students in experimental thermofluids, including the development of optical measurement techniques for droplets, sprays and other complex flows. These subjects are often linked to applications in energy (fuel efficiency, energy recovery, carbon capture), manufacturing (Minimum Quantity Lubrication) and medical devices (bioartificial organs, optical implants).

I have supervised 14 PhDs to completion and examined 20 PhDs in the UK, France, Denmark, Malaysia, and Australia. I currently supervise 3 PhDs researching spray systems and complex fluids (Paul McGinn, Alex Gander, Louis Dacanay).

Project in detail: Optimising host response biology to advance wound dressing efficacy 

Chronic, non-healing wounds affect 22 million patients annually. Whilst advances have been made in antimicrobial and moisture protecting dressings there remaining significant challenges in providing dressings which can resolve chronic inflammation within the non-healing wound bed. One of the most important considerations is optimisation of the interface between the dressing and the wound bed in order to moderate hyper-inflammation and promote wound healing. This can be done through biomimicry in which host response biology is taken into account to improve protein interactions, prevent biofouling and other negative triggers which repress wound resolution. The aim of this study is therefore to profile and optimise wound resolution processes using dressings modified with biomimetic macromolecules for improved tissue integration and healing.   

In the first part of the study a profile of the wound bed environment will be created using wound dressing exudate (Sandeman, Crua). The interaction and penetration of protein, cells and fluid within wound dressing materials will be considered (Sandeman, Crua, Sarker). Surface modification with biomimetic macromolecules and their impact on these interactions will then be investigated in order to optimise biointerfacial phenomena, improve dressing biocompatibility, efficacy and promote wound healing (Sandeman, Crua, Sarker).
