TRI/Princeton Appoints Principle Scientist

TRI/Princeton has appointed Trefor Evans, PhD, as principal scientist in measurement science. Evans has a BS in chemistry from the North East Wales Institute of Technology and a PhD in Physical Analytical Chemistry from the University of Toledo. After receiving his PhD, Evans joined the surface science laboratory at Helene Curtis as senior scientist. He worked extensively in product development, addressing several research concerns including product stability, manufacturing, performance and packaging.

 “We are delighted that Dr. Evans is joining the Institute,” stated Gail R. Eaton, PhD, president of TRI/Princeton. “Considering his impressive background in measurement science and hair chemistry, Dr. Evans will be a fantastic asset to TRI’s cutting-edge fundamental and contract research.” 

Before joining TRI/Princeton, Evans was a development manager in measurement science at Unilever, where he reportedly honed his expertise in thermal analysis, cosmetic formulation, and mechanical testing techniques, as well as his managerial skills. Evans was awarded the Joseph P. Caudelli Award in 1994 from the Society of Cosmetic Chemists. He plans to employ his knowledge of polymer and adsorption chemistry and product formulation to advance TRI’s hair measurement capacities and provide TRI’s clients with novel, market-forward approaches to hair testing and product development. Additionally, Evans hopes to use his experiences running an in-vitro hair testing laboratory and teaching on-site hair chemistry classes to optimize TRI’s ongoing continuing education programs.
