Profile

On completion of a PhD in Analytical Chemistry in 1983 my first academic appointment as a chemistry lecturer was at the then Thames Polytechnic, now Greenwich University, in Woolwich, London. In 1991 I left Thames as a Reader in chemistry to join the staff at Hull University and was appointed to a personal chair in 1998. In addition to my teaching and research commitments I am currently Deputy Dean Research and Enterprise for the Faculty of Science.

Following early research in the 1992/3 into developing the first micro fluidic flow injection system, my Micro Reactor Research Group at Hull has now carried out over 300 man-years of research funded primarily by UK research councils, to establish the design and operational parameters that give micro fluidic devices significant advantages in the field of chemical and biology research. In the past few years the Group has focused more on system and process integration, manufacturability, diagnostics and exploiting the biomimetic aspects of micro fluidic devices with a particular emphasis being place on biomedical/clinical type applications.

Highlights from the Group’s research include:

The development of a micro fluidic based Lab-on-a-chip system funded by EPSRC that can produce a DNA forensic profile in one hour with no moving parts (reagents and sample are pumped by electric fields), in which all the reagents are preloaded into the device using gels to avoid the possibility of contamination.

Establishing micro fluidic based methodology that can maintain viable biological tissue for many days in order to enabled the study of cell function within both normal and diseased tissue environments. The methodology has been used to study drug therapy strategies applied to biopsies taken from head and neck carcinomas in order to establish a personalised medical prognosis.
