Biography
Dr Jonathan Crowther has worked for 13 years in the cosmetics industry (2003 to 2012 for Procter and Gamble, and 2012-2106 as a consultant and now with GSK), in fields ranging from new product research with novel materials through to developing and running clinical studies to provide claims support data for product launches. Research areas worked on include moisturizers, cleansers, and hair removal methods (shaving, waxing, epilation, depilatory creams, light based hair removal).
His main area of focus has been the development and understanding of methods used to measure skin. He has hands on approach to science and is experienced with the operation and use of a wide range of skin testing equipment including Corneometer, Sebumeter, TEWL, colorimetry, Confocal Invivo Raman Spectroscopy (for hydration profiles and ingredient penetration), Photographic Imaging techniques, skin grading, tape stripping and SEM, and clinical test design.
After building his expertise in the skin methods field he also became more involved with teaching the science of skin measurement, to audiences from dermatologists to journalists and marketing groups. He is also strongly linked with ongoing academic research and is a visiting scientist with University College London.
He graduated from Durham University with a BSc in Chemistry in 1994, and went on to do a PhD in Surface Modification and Analysis which he completed in 1997, and loved the research so much that he stayed on for extra 3 years as a Post Doctoral research assistant. During this time he developed a strong Analytical chemistry background with a wide variety of surface analytical techniques (XPS, Auger, ToF SIMS, Raman, ATR-IR, SEM and TEM, AFM) for materials analysis, along with cold plasma treatment of materials for the manufacture of metal surfaces and ultra low energy materials. It is the cross discipline background he has from working at the boundaries between chemistry, physics and engineering, which he has now applied to his assessment of skin.
