Mark W. Spears Jr., Ph.D.

Southeast Regional Manager & Applications Scientist

Mark W. SpearsMark completed his PhD work in Analytical Chemistry at Georgia Tech. He studied under Professor L. Andrew Lyon and developed expertise in many analytical techniques including SEM, AFM, DLS, and MALS. Mark’s graduate work centered on the synthesis and applications of acrylamide-based polymer nanoparticles known as microgels. In particular, he was interested in using microgel assemblies as novel coating materials and characterizing the fundamental properties of the coatings that control how various cell types behave on the surface.

Mark joined Wyatt in 2015 and now lives in Cary, NC. He is responsible for sales, support, and instrument installations in the southeast – an ever expanding challenge! Mark is dedicated to providing the best ownership experience possible, and he enjoys helping to advance research in many areas of study.

Wyatt Technology is the recognized leader in light scattering instrumentation and software for determining the absolute molar mass, size, charge and interactions of macromolecules and nanoparticles in solution.

Wyatt's line of multi-angle static light scattering products couple to size exclusion chromatography (SEC-MALS), field-flow fractionation (FFF-MALS), and stop-flow composition-gradient systems (CG-MALS). Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. We also offer unique instruments for electrophoretic light scattering (MP-PALS), differential refractometry, and differential viscosity.
