David has been involved in biophysical studies of skin, biological membranes, and topical formulation development for 25 years. From 2013 to 2020 David lead skin health R&D activities at GlaxoSmithKline in North Carolina, New Jersey, and London. Prior to this, David led industrial R&D groups focused on skin membrane biophysics, FTIR spectroscopy and spectroscopic imaging, measurement science, and topical formulation development at Unilever, International Specialty Products (now Ashland), and TRI-Princeton. In addition to his industrial roles, David has held visiting academic positions at Rutgers University, Princeton University, the University of Cincinnati, and University College London. David has served as an industrial advisor and sponsor to doctoral students at Stanford University, Princeton University, Vanderbilt University, and Rutgers University in the US and University College London, Imperial College, and the universities of Newcastle, Durham, Leeds, and Edinburgh in the UK. The co-author of over 100 peer-reviewed papers, review articles and book chapters in the fields of skin barrier science, topical delivery, lipid biophysics, and membrane spectroscopy, David is an elected fellow of the Royal Society of Chemistry and was co-chair of the 2019 Gordon Research Conference on The Barrier Function of Mammalian Skin. In 2022, David was appointed as an honorary professor in the School of Physics and Astronomy at the University of Edinburgh where he works closely with the Edinburgh Complex Fluids Partnership. A native of Edinburgh he has recently returned home after many years working in the US.
