As director of Lehigh's Center for Polymer Science and Engineering and the Microelectrics Packaging Materials Lab, Dr. Pearson's research focuses on the fracture of polymeric materials, and has evolved into three specific directions. The first elucidates fracture mechanisms in bulk polymeric materials (blends and composites). The second studies fracture mechanisms and molecular interactions at bimaterial interfaces (microelectronic packaging). The third involves development diagrams to express the processing behavior of thermosetting resins (microelectronic packaging). His lab is currently funded by NASA, Arkema, Zymet, Pennsylvania Infrastructure Technology Alliance, and IBM.

He has authored 60 refereed publications and eight textbook chapters, presented nearly 100 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 International Microelectrics and Packaging Society, Arkema, IBM, American Chemical Society, ASM International, the American Society for Engineering Education, and National Science Foundation. He is a member of the American Chemical Society Division of Polymer Chemistry and Division of Polymeric Materials Science and Engineering, ASM International, Materials Research Society, Sigma Xi - The Scientific Research Society, and Society for the Advancement of Material and Process Engineering. He is also a fellow of the Society of Plastics Engineers.
