Prior to Pastel BioScience, Stephen worked for 11 years as senior scientist in both the biotechnology and diagnostic industries and currently acts as a consultant to other companies in these areas. He also has experience in the equity and VC markets working for a number of years as a biotech and pharma financial analyst at a leading London Stockbroking firm.

Stephen obtained a BSc in Biotechnology from the University of London and a Ph.D in Biochemical Engineering from UCL. His research interests were in the area of aqueous/organic two-phase biocatalytic systems and he has published not only in this area but also in the fields of prokaryotic and eukaryotic recombinant protein expression for use in diagnostic assays and novel assay design.

Dek Woolfson

Scientific Advisor to Pastel

Dek Woolfson is currently Professor of Biochemistry at the University of Bristol and prior to that the same position was held at the University of Sussex. Dek has published extensively on the principles and properties of alpha-helical coiled-coils and protein engineering in general. He heads a research group studying the self assembly of peptides into fibres and peptide conformational switching, both areas that have significant applications in nanotechnology and tissue engineering.

Dek obtained his B.A in chemistry from the University of Oxford and his Ph.D in chemistry from the University of Cambridge. Along with a plethora of scientific publications and citations he has also patented much of his research and is exploiting them through commercial license agreements.

Mark Osborne

Scientific Advisor to Pastel

Mark Osborne is currently a lecturer and Royal Society University Research Fellow (Chemistry) at the University of Sussex. He received his B.Sc. in Chemical Physics (University of Sussex), D. Phil. (School of Molecular Sciences, University of Sussex) and performed postdoctoral research in single molecule spectroscopy in the group of Dr David Klenerman (University of Cambridge).

Mark was a member of the founding group, and worked for 3 years as a senior scientist (single molecule detection) with Solexa Ltd, Cambridge, UK and is the inventor on a number of Solexa’s original patents. Current research is directed at single molecule biomolecular dynamics within bio-mimetic environments combining techniques including laser spectroscopy, CCD imaging, confocal fluorescence and total internal reflection microscopy.
