Professor Pearson is very active delivering courses using an online format as part of Lehigh’s Distance Education efforts. Professor Pearson's research focuses on the fracture of polymeric materials, and has evolved into three specific directions. The first direction elucidates fracture mechanisms in bulk polymeric materials (blends and nanocomposites). The second studies fracture mechanisms and molecular interactions at bimaterial interfaces (structural adhesives). The third direction involves developing polymers for additive manufacturing processes such as direct ink writing (DIW), fused filament fabrication (FFF), and selective laser sintering (SLS).  His lab has received funding from various government agencies as well as from private companies.

He has authored over 60 peer reviewed publications and 8 textbook chapters, presented over 125 conference papers and numerous conference presentations in the U.S. and abroad. He has also edited volumes for the American Chemical Society, Materials Research Society, Polymer Engineering and Science, and American Society of Mechanical Engineers.

Pearson has won awards from the Adhesion Society, Arkema, American Chemical Society, ASM International, the American Society for Engineering Education, IBM, International Microelectrics and Packaging Society, and National Science Foundation. He is a member of the American Chemical Society Division of Polymer Chemistry (POLY) and Division of Polymeric Materials Science and Engineering (PMSE) , Society for the Advancement of Material and Process Engineering (SAMPE) and the Society of Plastics Engineers (SPE). In 2010, Professor Pearson became a fellow of the Society of Plastics Engineers. He is currently a Vice President of Technology and Education for SPE and is an Associate Editor for the Journal of Polymer Composites.
