Senior Scientist II

Department of Biotechnology

1996 – 1998 Post-doctoral Fellow, The Lawson Health Research Institute,University of Western Ontario, London, Canada



Dr. Sampath Kumar is presently a Senior Scientist II at Adimab LLC, where he leads a group building technology platform for Cell line development, protein expression and cell culture. He earned a Ph.D. in biology (developmental endocrinology) from the National University of Singapore. He thenconducted post-doctoral research first at The Lawson Health Research Institute (London, Ontario, Canada) and then at the University of Maryland Biotechnology Institute (Baltimore, Maryland). His research in both labs focused on molecular reproductive endocrinology,

He began his biopharmaceutical/biotechnology career at CuraGen Corporation in 2002. He has since worked for Wyeth, Pfizer and Biogen. He has worked on a variety of proteins that include antibodies and difficult-to-express clotting factors (factors IX, VII, VIII, X and VWF). He employs cell and molecular biological tools to i) understand the post-translational limitations to expression of therapeutic proteins, and ii) to study the effect of culture conditions on productivity and protein product quality in cell culture.


Research Interest

His expertise include generation of manufacturing/clinical-grade stable cell linesand cell culture process development.
