Caroline Hall

Caroline Hall, PhD

Flow Cytometry Technical Product Specialist

Caroline began her research career at the University of Hawaii at Hilo where she gained her Bachelor of Science in Cell and Molecular Biology. While attending university she worked as a research assistant studying tropical infectious avian diseases. She later received her Ph.D. in Microbiology and Immunology from the University of Texas Health Science Center in San Antonio, Texas where her research focused on characterizing the effects of age on T cell function in non-human primate models. Caroline went on to accept a post-doctoral fellowship with the U.S. Army Institute of Surgical Research located at the San Antonio Military Medical Center, where she investigated the role of antifibrotic agents on tissue remodeling in hypertrophic scarring following traumatic injury. She brings over 10 years of experience in the fields of immunology and cell biology to her role at Thermo Fisher Scientific, first as a Field Application Scientist specializing in flow cytometry, and currently as a Technical Product Specialist. Caroline lives in Colorado with her husband and two dogs where she enjoys hiking and camping with her family. She is passionate about traveling and is working on her goal to visit all 50 states.

Apart from science, Shilpi enjoys soccer, badminton, and pottery as hobbies.

Swathi SundarRaj

Swathi SundarRaj, PhD

R&D Scientist

Swathi SundarRaj studied classical immunology and spent years in graduate school killing millions of T cells to understand how they die. From there, Swathi continued to study immune evasion and tolerance mechanisms and application to translational medicine, before jumping into development of tools with which to study the immune system. Swathi is constantly amazed that a system so mind-bogglingly complex has evolved purely by chance! At Thermo Fisher Scientific, Swathi is working towards generating recombinant antibodies against critical immunological molecules.
