Associate Director

Alex Krotulski

Dr. Alex J. Krotulski serves as an Associate Director at CFSRE working in the areas of forensic toxicology and forensic chemistry and is the Program Manager for NPS Discovery, the CFSRE’s drug early warning system and flagship program for the identification and characterization of new and emerging synthetic drugs.

Dr. Krotulski is analytical chemistry by training and practices as a forensic toxicologist. Dr. Krotulski holds faculty appointment and serves as the Assistance Program Director for the Thomas Jefferson University Master of Science in Forensic Toxicology (MSFT) program and was recently appointed as an Associate Editor for the Journal of Analytical Toxicology.

Dr. Krotulski received his Doctor of Philosophy degree in Analytical Chemistry from Temple University in 2019 following receipt of his Master of Science degree in Forensic Science from Arcadia University in 2015 and Bachelor of Science in Chemistry from Loyola University New Orleans in 2013. To date, Dr. Krotulski has authored or co-authored more than 45 publications in the areas of forensic toxicology, clinical toxicology, and forensic chemistry, in addition to more than 65 presentations across various areas of forensic science, mass spectrometry, and analytical chemistry, and has severed a chair, co-chair, or moderator for more than 8 workshops and webinars. Dr. Krotulski’s current research and casework focus heavily on aspects related to the detection and characterization of novel psychoactive substances (NPS), including studies that examine NPS positivity, trends, metabolism, and effects through NPS Discovery’s intelligence, surveillance, monitoring, and response efforts.

For his contributions to the field of forensic toxicology, Dr. Krotulski was awarded the inaugural 2021 Society of Forensic Toxicologists (SOFT) Research in Forensic Toxicology Award and the 2022 American Academy of Forensic Sciences (AAFS) Toxicology Section’s Irving Sunshine Award for Outstanding Research by a Young Investigator. In addition, Dr. Krotulski was awarded the 2020 Young Forensic Scientists Forum (YFSF) Founder’s Award and 2017 AAFS Toxicology Section’s Best Poster Award and has received honors for his Journal of Forensic Sciences (JFS) Noteworthy Article involving the synthetic cannabinoid 4F-MDMB-BINACA. In 2020, Dr. Krotulski was appointed to serve as the Guest Editor for the 2021 Special Issue in the Journal of Analytical Toxicology.

Dr. Krotulski remains an active member of several professional organizations including the Society of Forensic Toxicologists (SOFT), the American Academy of Forensic Sciences (AAFS – Toxicology Section), The International Association of Forensic Toxicologists (TIAFT), the International Society for the Study of Emerging Drugs (ISSED), and the International Alliance of Clinical and Forensic Toxicologists (IACFT). Dr. Krotulski serves on various committees across these organizations, including SOFT’s NPS Committee and Young Forensic Toxicologists Committee, and has completed various other roles with respect to planning committees, program committees, and working groups. For his expertise in high-resolution mass spectrometry and its applications, Dr. Krotulski has been designated as a “Thought Leader” with SCIEX.
