(cannabis) pharmacology, from the University of Louisville. Dr. Kumar is a cannabinoid research
scientist, pharmacologist, laboratory manager and consultant trained in ensuring Quality
Assurance/Quality Control (QA/QC), current Good Manufacturing Practices (cGMP), current
Good Production Practices (GPP), and current Good Laboratory Practices (cGLP) of
pharmaceutical products and Active Pharmaceutical Ingredients (APIs). Currently, Dr. Kumar is
the CEO of PhytoSciences and leads a team of 40+ global scientists / physicians with a primary
focus of developing safe, consistent, and pure medicinal cannabinoid-based therapeutics. Overall,
Dr. Kumar’s experience and expertise lead the product development operations at PhytoSciences
and their team consults in the areas of R & D, manufacturing, bioprocessing, clinical trial solutions,
and laboratory development pertaining to cannabinoid-based therapeutics.
Dr. Kumar has provided consulting services to several U.S. state government officials as well as
international governments and policy officials on effective medical cannabis policies and regularly
advises on laboratory facility design / optimization, cannabis testing equipment, analytical
methodology for cannabinoid analysis and separation, pharmacology of cannabis-based
therapeutics and maintaining a QA system to ensure compliance, including preparation of
legislative documents to regulate a QA system with regard to cannabis manufacturing and
Previously, at the University of Louisville, Dr. Kumar conducted pharmacological testing of FDA-
approved drugs as potential ligands for the cannabinoid receptor 2 (CB2) and investigated the
pharmacology of cannabidiol (CBD). Currently, Dr. Kumar is the primary investigator of the
largest harm-reduction cohort study across Canada investigating medical cannabis as a potential
substitute for opioids for chronic pain patients.
He has received numerous honors and awards including Best Oral Presentation from the
International Cannabinoid Research Society (ICRS) Conference in Vancouver and fellowships
