Biography

Barbara was appointed as Professor of Pharmaceutics at the University of Huddersfield in 2010. Following her first degree in Pharmacy at Queen’s University, Belfast, she registered as a pharmacist in 1990 and practised full-time in community pharmacy until joining Aston University in Birmingham in 1992 to undertake a Ph.D. Her PhD research project at Aston was in the pharmaceutics and drug delivery field, focusing on microencapsulation for delivery of biopharmaceuticals.

Following completion of her PhD studies in 1995, she was employed in various posts at Aston University, including lecturer and senior lecturer and was Director of the M.Pharm. programme prior to moving to the University of Huddersfield in 2010 as Professor of Pharmaceutics. During this time, she also became a Fellow of the Higher Education Academy and supervised projects on the application of e-learning technologies in Pharmacy. She was also a Medici Fellow, specialising in driving forward innovation within the university sector and hold several patents in the pharmaceutical area. She has supervised over 20 Ph.D. students and on-going research programmes focus on chrontherapeutic delivery and delivery of antimicrobials, novel excipients for drug delivery, the mechanical properties of pharmaceuticals and excipients and the development of chewing gum delivery systems.

She has a number of successful collaborations with other universities, NHS and pharmaceutical industry leading to publications and development of new products.

Research & Scholarship

Her research encompasses the improvement of traditional and development of novel drug formulations in relation to stability, bioavailability and patient compliance. A major barrier to introduction of new chemical entities onto the market as novel therapeutics is the design of efficient delivery systems for drugs that are poorly soluble, unstable, or are of low permeability. Research in the group focuses on application of pharmaceutics, with the aim of improving delivery of challenging molecules through biological membranes and barriers with particular emphasis on rational formulation design and the introduction of innovation.

Understanding the fundamental physical properties of delivery systems in relation to their performance is key and one research strand focuses on the characterising the relationship between solid state properties and the performance of pharmaceutical materials, for example the prediction of mechanical properties of salt forms of drugs based on their crystal structures with a view to improving processing.

Other research strands involve the development of formulations for oral, ophthalmic and transdermal drug delivery, the design of modified release systems, including the use of mucoadhesives, fast-dissolving and chewing gum formulations and the enhancement of solubility and dissolution for poorly soluble drugs. It is essential to address both physiological and physiochemical barriers to drug absorption with a view to developing improved formulation strategies in clinical practice, for example, effective delivery of antiseptics into the lower layers of the skin to improve asepsis.

Research Degree Supervision

Pharmaceutical salt formation and characterisation

Salt formation has been studied extensively as a strategy to improve drug solubility and a range of different counterions can be used. This modification will also alter the mechanical properties of a drug and the type of counterion will be important in determining those properties. A better understanding of which factors of the solid state can have an influence in the mechanical properties of pharmaceutical powders can help to optimise and reduce cost of tablet manufacturing. The aim of this project is to form different series of salts of poorly soluble and poorly compressible acidic drugs and to establish predictive relationships between architectural characteristics and physicochemical and mechanical properties of the salts.

Skin antisepsis

Appropriate skin antisepsis to reduce the number of microorganisms on the skin prior to carrying out an invasive procedure is critical, as it decreases the risk of subsequent infection. However, skin antisepsis does not eradicate all the microorganisms associated with the skin. This is probably related to the limited skin permeation of antiseptics and the presence of microorganisms residing in the deeper layers of the skin. This aim of this project is to develop formulations better designed to target these sites within the skin.

Development of oromucosal drug delivery systems

Targeting the buccal mucosa can be an effective route for drug absorption avoiding complications associated with conventional oral delivery systems. In order to facilitate absorption, the drug must be presented to the mucosa in an absorbable state from a dosage form that can enhance uptake by this route. Using a range of in vitro techniques, this project will focus on strategies to enhance buccal absorption. Correlation between rates of release and buccal absorption will be developed for a range of dosage forms.

Nonaparticulates for drug delivery

Nanoparticles can be used for targeted drug delivery, to improve bioavailability, to prolong drug release, and to enhance the dissolution of drugs with limited aqueous solubility. Penetration of drugs applied to the skin may occur via the stratum corneum or by the skin appendages such as sweat glands and hair follicles. Recent studies have shown that the hair follicles can be targeted using nanoparticles and this project will involve the development and characterisation of follicular delivery systems.
