About RSR Laboratories
Anthony J. Repay, M.S.
Director of Microbiology
Anthony Repay earned his Bachelors of Arts in Biology with a minor in chemistry from Wabash College. After gaining experience in the field, Anthony then attended Purdue University to obtain his Masters of Science degree in biology with a focus in Microbiology. Most of Anthony’s experience stems from working in the environmental and food microbiology field including the testing of: Salmonella, E.coli, Legionella, coliforms and many other general microbial tests.
Anthony began his career at Microbac laboratories, starting in the organics/ wet-chemistry department. After roughly a year, he transferred to the microbiology department while also getting his masters degree at this time. Upon graduation, Anthony was promoted to be the Supervisor of Environmental and Food microbiology for the Chicago-land location.
While at Microbac, Anthony gained the essential skills needed to lead a team of microbiologists as well as improve the traceability and efficiency in a laboratory setting. Though RSR analytical is his first experience in the cannabis industry, Anthony is confident that the skills he has picked up through food and environmental work will go hand and hand.
Joseph A. Haun
Joseph Haun earned his Bachelors of Science in Forensic Chemistry from Youngstown State University. Joseph’s background consists of various forensic applications utilizing analytical chemistry, such as, forensic drug testing, arson investigation, analyzing for controlled substances, and crime scene analysis.
Joseph began his career at OMEGA laboratories, the leader in forensic hair testing, where he gained experience in qualitative ELISA testing followed with confirmatory GCMS work in compliance with ISO/IEC 17025 standards. Following this, his time was spent as a research assistant at his alma mater. During this time Joseph first became published for his work on The Effects of Liquid Latex as an Absorbent on Human DNA. He also assisted in developing the use of liquid latex for soot removal from fire scenes and attempted fingerprint development with Ninhydrin.
Joseph was first introduced to working with cannabis as a forensic chemist I working with controlled substances for NMS Labs. At this time, Joseph gained valuable experience in QAQC practices, uncertainty of measurement, traceability, and data analysis that has applied to his role as the quality manager here at RSR. While at NMS Labs, Joseph also gained a specialization in analytical GCMS testing producing results dependable in court. Since then Joseph has joined the team at RSR to assist in performing state required marijuana compliance testing while helping develop the quality management system used to ensure compliance with ISO/IEC 17025.
David Luttrull, Ph.D
Dr. David Luttrull earned a Ph.D in Physical-Organic Chemistry from Arizona State University in 1991 with a dissertation in the area of artificial photosynthesis and earned a NSF Postdoctoral Fellowship at the Center for Change Transfer Studies at the University of Rochester. He began his career as a Senior Chemist in 1992 at Nalco Chemical in Sugarland, TX, where he developed and synthesized gasoline additives. In 1997, he accepted a position as a Material Scientist, which quickly became an R&D Director position at Neltec, INC., in Tempe, AZ. In 2004, he went to work for Rosestreet Labs, in Phoenix, and in 2007, Dr. Luttrull started up his own analytical lab, MG Lab Services (Malcom Grey, LLC). Dr. Luttrull’s activates included consumer product testing for Lead (Pb) and cadmium (Cd), precious metal assays for small mining companies, diagnostic chemistry for forensic engineering companies, analytical support for electronic materials manufactures and military contractors.
In 2010, Dr. Luttrull accepted the position of Sr. Director of Emerging Technologies at Isola Group. Isola Group is a large dielectric materials manufacturer based in Chandler, AZ. Isola approved Dr. Luttrull’s proposal to build a million dollar laboratory facility, which included a new 300MHz NMR. Dr. Luttrul left the Isola Group in the late 2013 to pursue chemical consulting and new product ideas. Dr. Luttrull has over twenty one publications, including two patents and nine scientific papers in peer-reviewed journals.
Dr. Luttrull will serve as a paid consultant to CANNEX Nevada, LLC with the responsibilities to oversee the training of methodologies, lab set-up and the proper use of all testing instrumentation. This will ensure that all testing is performed consistent to the testing standards set forth in NAC 453A Sec.118.
