GemSeal is pleased to announce and welcome Sherry Guo, Ph.D. as our new Director of Research and Development, working out of our Tampa, FL, location. She has joined us from Royal Dutch Shell, Inc.-Shell Bitumen-U.S. where she served as Shell Oil Products, Sr. Product Application Specialist and then as Specialties Technical Sales Manager.  While there, Sherry was instrumental in the successful development of the Shell Tixophalte, a high performance, cold-applied crack sealant now being introduced in the US Market.  She also made significant contributions to Shell Bitumen in both Paving and Roofing in her role as Technical Manager and Sr. Technical Specialist.

Sherry is the co-author of two patents, one international; “A preparation method of polymer-modified asphalt component,” and one US; “Storage-stable modified asphalt composition and its preparation process.”

Before Shell, Sherry worked for Martin Asphalt in Texas as Sr. R&D Chemist, where she led and implemented new product development, cost reduction, and raw material optimization. She also worked at KOCH Material Company and SINOPEC, China, for several years.

Sherry holds degrees in Organic Chemistry, Analytical Chemistry, and a Ph.D. in Applied Chemistry.  She brings with her a deep understanding and experience of asphalt/bitumen products, oil refining, and crack sealing.

Her addition to the GemSeal team underscores our dedication to developing the best performing products in the industry and our commitment to future growth.  Sherry and Paul Raymond have joined forces giving us a dynamic R&D team.
