John DesJardins: Inventor Spotlight

Written by   in 

Dr. John DesJardins, the Hambright Leadership Associate Professor of Bioengineering at Clemson University, has worked to change the scientific community with his knowledge and innovative research in orthopedic biomechanics and biomaterials. Since being at Clemson, DesJardins has been awarded and recognized for his work in orthopedics, rehabilitation, implant design, and sports medicine.

DesJardins first became a part of the Clemson family as a research technician, and received his Ph.D. in bioengineering in December 2006. Having served as an employee, student, and faculty member at Clemson for over 20 years, DesJardins has made a substantial impact on the University research enterprise. While at Clemson, DesJardins has co-authored over 300 peer-reviewed conference or journal publications based in biomechanics, biomaterials, tribology, engineering education, and mechanical testing. He is the director of the Laboratory of Orthopaedic Design and Engineering at Clemson University and the Frank H. Stelling and C. Dayton Riddle Orthopaedic Education and Research Laboratory at CUBEInC. He currently serves as the lead on several multidisciplinary research projects. In addition to his many accomplishments as an inventor, DesJardins works to encourage and empower the next generation of inventors through his work with the University Innovation Fellows and the Design and Entrepeneurship Network (The DEN). He is the director of the Clemson senior capstone design courses where he helps several students develop innovative biomedical devices, and he leads an undergraduate bioengineering study abroad program in Spain that focuses on international bioethics.

As an inventor and resource for student inventors, DesJardins has been able to significantly impact the research landscape at Clemson University. From inventing to teaching, DesJardins will continue to be a force in research for years to come.

Ken Marcus: Inventor Spotlight

Written by   in 

Clemson University chemistry professor, Dr. R. Kenneth Marcus, has made a substantial impact on the scientific community with his innovative research. Having served as a faculty member at Clemson for over 30 years, Marcus has received several patents and awards for his work in the development and application of new plasma techniques for the atomic spectroscopic analysis of diverse materials.


Marcus began his career as an inventor during his time as a graduate student at the University of Virginia, where he received his first patent for a novel excitation and ionization source for the elemental analysis of solid materials. In 1986, he graduated with a patent and a Ph.D. in analytical chemistry. In addition to his individual accomplishments as an inventor, Marcus takes great pride in molding the next generation of researchers. At Clemson, he works extensively with a research group made up of several Clemson University Ph.D. students. The group’s research is rooted in analytical chemistry but has two unique fields of study. Marcus’s group has developed the Liquid Sampling – Atmospheric Pressure Glow Discharge (LS-APGD), a novel atmospheric pressure glow discharge source that is being used as a spectrochemical means for optical emission and mass spectrometric analysis. The second research focus centers on a protein separation method that uses capillary-channeled polymer (C-CP) fibers as high-performance liquid chromatography (HPLC).


A long-time contributor to science and the futures of his many students, Ken Marcus is valued not only as a Clemson faculty member, but also as an inventor. Currently, Marcus serves on the editorial boards for three international journals and has received several notable honors including the 2001 S.C. Governor’s Award for Excellence in Science Research, and is a Fellow in multiple societies including the Royal Society of Chemistry (London), and most recently, the National Academy of Inventors.

John DesJardins

Assistant Professor, Bioengineering
Director of Bioengineering Abroad Programs

Dr. John Desjardins is the founder of the Clemson University Retrieval of Explants Program and Registry in Orthopaedics (CU-REPRO), which is a regional repository that collects and studies explanted total joint devices. He also serves as the Director of the Laboratory of Orthopaedic Design and Engineering at Clemson University, and the Frank H. Stelling and C. Dayton Riddle Orthopaedic Education and Research Laboratory at CUBEInC. His research interests include total joint replacements, orthopaedic biomechanics, and biomaterials – about which he has co-authored over 150 peer-reviewed conference or journal publications.

Dr. Desjardins also founded Clemson’s undergraduate bioengineering study abroad programs, and directs/assists with international programs in Spain, Singapore, and Tanzania. He currently leads or is a co-PI on many multi-disciplinary research teams for projects funded through NASA, DoT, NSF, the Gates Foundation, biomedical industry and other regional non-profit foundations. As an assistant professor in Bioengineering, he is the director of the senior capstone design courses, where he mentors 15+ small teams annually to develop innovative biomedical devices in partnership with local industry or clinical partners.
