Andrea Holmes, PhD

Professor of Chemistry at Doane University

About Me

Dr. Andrea Holmes is a Professor of Chemistry at Doane University in Crete Nebraska and the Chief Growth Officer of Precision Plant Molecules in Denver, Colorado. In 2018, Dr. Holmes was appointed as a Ph.D. scientist at AgriScience Labs in Denver, a state-certified and ISO audited marijuana-testing lab. At AgriScience Labs, Dr. Holmes tested marijuana consumer products for potency, residual solvents, terpenes, pesticides, yeasts, molds, salmonella, and e-coli. She also conducted her own research and developed an automated image analysis for counting yeast and mold colonies in marijuana, eliminating the need for a microbiologist to count the colonies manually. While at AgriScience Labs, Dr. Holmes helped develop a portable cannabis colorimetric sensor that is able to detect and quantify THC.


As the Chief Growth Officer at PPM and a senior management member, Dr. Holmes has pioneered a new, consumer-driven market of THC free cannabis-based products. She has also headed up the efforts to push new frontiers of science in the discovery of novel minor cannabinoids that are known for wellness benefits.  In her on campus classroom at Doane University, Dr. Holmes teaches organic chemistry and applies classical organic chemistry concepts and topics to cannabis chemistry.
