Jeff Angermann, PhD

Affiliate

Dr. Angermann is a founding member of 374 Labs, LLC, and has been active in the cannabis industry since 2013. 374 Labs was the first laboratory in Nevada to achieve ISO 17025 certification and certify medical cannabis products for sale in 2015, prior to the state's legalization of recreational cannabis in 2017. He is an active member of the AOAC International Cannabis Analytical Science Program, and currently serves on the Microbial Contaminant Expert Review Panel, where he has the opportunity to evaluate emerging methods of microbial contaminant detection. 

 

His primary specialization is the remote and onsite assessment and remediation of microbiological contaminants in cannabis cultivation and production facilities; In Nevada, he has conducted 15 full facility audits to date, saving cultivators and producers millions of dollars in revenue from the avoidance of harvest and production lot failures. Dr. Angermann has extensive experience with analytical and microbiological method development, and specializes in adapting existing cannabis laboratory methods to the requirements of individual state markets. Dr. Angermann also develops methods and low-cost instruments for contaminant testing of both cannabis and nicotine vape products.

Carl Yamashiro, PhD

Dr. Yamashiro brings more than 25 years of R&D industry experience in the biotechnology and in vitro diagnostics arenas. This includes executive and senior leadership positions and R&D management positions in large medical device and diagnostics companies, as well as the VP of Product Development at PathogenDx, where he led efforts in assay development for pathogen detection using microarrays for botanicals, food and environmental testing/monitoring, as well as strategic planning and technology assessments.

 

Carl believes the future of cannabis safety must include regular environmental testing to mitigate the financial losses related to yeast and mold contamination in cultivation, manufacturing, and laboratory facilities to demonstrate adherence to GMP production and ISO 17025 standards.
