TRI Mission

TRI/Princeton is an independent, non-profit scientific research and education organization founded in 1930 by an act of US Congress.  Over the decades, TRI has evolved into a full-service independent research and testing facility, specializing in porous materials, textiles, fibers, bio-materials, polymers, and films. TRI provides research solutions to a wide variety of domestic and international industrial companies, governmental organizations, and academic institutions.

With our range of instruments and methodologies, characterization goes well beyond just visualization, but deeper into the analysis, identification, and localization of molecular and structural components within the sample. Our technical platform encompasses a powerful set of cutting-edge tools and techniques along with complementary approaches for material characterization and analysis, especially well-suited for the study of bio-materials such as hair, skin, nail, bone and/or teeth.  These analyses and information can then be correlated to a host of different biophysical parameters. Furthermore, our techniques are exceptional in applications for testing, understanding and comparing variations or changes in biomaterials with relation to specific conditions like aging, diseases, environmental stresses (e.g. UV exposure), chemical exposure, and product treatments (product application or drug therapy). More importantly, changes that occur in these biomaterials and bio-substrates as a function of various factors (whether extrinsic or intrinsic influences) can be established and monitored in specific areas of interest such as at the surface or deep inside the structures of interest.

ASamuel Gourion-Arsiquaud headshots a Principal Research Scientist at TRI Princeton, Dr. Gourion-Arsiquaud uses various spectroscopic and microscopic techniques for the characterization of biomaterials and the study of biological modifications associated with specific conditions like treatment, drug use, disease, age or environmental factors. Dr. Gourion-Arsiquaud’s expertise lies in multiple biophysical techniques with a special emphasis on vibrational spectroscopies (FTIR & Raman) for biomaterial sciences. He has more than 10 years of research experience, including technique development, project design and coordination, as well as a successful track record of technical and innovative achievements. Dr. Gourion-Arsiquaud has extended the instrument application to biological tissues relevant to cosmetic; teeth, nail, hair and skin.
