Erik Hedrick, Ph.D.

Associate Scientist

Erik Hedrick is an Associate Scientist here at The Burdock Group, a safety and regulatory consulting firm located in Orlando, Florida, with over 30 years of established experience as the leader in regulatory and scientific consulting. We are a brick-and-mortar establishment that has on-site accountability, our own in-house toxicological library, and access to state-of-the-art scientific databases, to provide the most up to date and comprehensive compilation of information to ascertain what steps are needed to bring a client’s product to market. We are the experts at conducting gap analyses, navigating the specific nuances of the regulatory space, and providing outside the box solutions that are specifically tailored to the unique needs of your product.

Erik received his Ph.D. in Toxicology in 2016 from Texas A&M University and has seven years of post-doctoral experience from Texas A&M University and the Lerner Research Institute of the Cleveland Clinic.

With ten years of toxicology experience relating to molecular toxicology and, over fourteen years of experience in cell/molecular biology, biochemistry, and molecular oncology, Erik has acquired extensive experience utilizing in vitro and in vivo molecular, biochemical, and analytical techniques as well as animal husbandry in the field of molecular toxicology and oncology. He has published 21 peer reviewed publications in multiple highly respected journals (listed below). During this time, Erik has successfully obtained highly competitive sources of funding for research which include, a Merit Scholars Fellowship and Research Training Grant at Texas A&M University, the National Institute of Health (NIH) Ruth L. Kirschstein National Research Service Award (NRSA) and the Early Investigator Research Award during his postdoctoral tenure at Cleveland Clinic. Erik has presented his work at multiple scientific conferences to include the Society of Toxicology (SOT) annual meetings.

As an Associate Scientist here at Burdock Group, Erik's role is to ensure the safety and regulatory compliance of a client’s product before it comes out onto the market. His experience in toxicology has equipped him with the toolset to understand the unique safety requirements for an ingredient and what tests are needed to demonstrate safety. During Erik's tenure at The Burdock Group, he has become familiar with specific regulations within the United States and the European Union. This includes working with the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) within the United States as well as with the European Food Safety Authority (EFSA) within the European Union (EU).

Erik's work has included composition of:

Feasibility assessments for Generally Recognized as Safe (GRAS) dossiers
GRAS dossiers
Food Additive Petitions (FAP)
New Dietary Ingredient (NDI) Notifications (NDIN)
Gap analyses and regulatory assessments
Substantial equivalence and standard of identity assessments
Development and monitoring of safety/clinical studies
Publishing safety studies and other manuscripts
Safety assessment monographs
EPA pesticide and facility registration and consulting
Novel Food Applications for authorization of novel foods within the European Union (EU).

Working at Burdock Group, Erik has also become familiarized with:

Organisation for Economic Cooperation and Development (OECD) guidelines
Good manufacturing practices (GMP)
Good Laboratory Practices (GLP)

Erik has conducted multiple webinars at The Burdock Group, which include:

Ensuring the safety of cannabinoids and navigating the regulatory space for their use as food ingredients and dietary supplements
Cell-cultured meat and alternative protein products and ensuring their safety for humans and animals
Algae-based food ingredients and dietary supplements for use in the United States and the EU

Erik's unbridled level of ardor and professionalism for scientific research and understanding of the regulatory space as it relates to occupational health and safety and ensuring the safety/compliance of new products, provides the firm with a significant advantage in the regulatory marketplace. Erik's Ph.D. in toxicology, along with his decade of experience in toxicology and molecular biology and biochemistry, allow him to swifty navigate any project to completion. Erik specializes in toxicological safety assessments, development and monitoring of safety/clinical studies, and regulatory consulting. This involves determining what information and studies are needed to ensure a client’s product is safe and compliant with current regulations before it comes out to the market. His work includes composition of GRAS, GRAS notifications, FAP, CAP, NDIN, safety assessments, Novel Food Applications, study monitoring and clinical trial development with CROs, manuscript preparation, pesticide registrations, and other regulatory assessments/documentation. Erik also has experience with the FDA, EPA, EFSA, FTC, and other regulatory bodies. He is familiar with OECD, GLP, GMP, GCP, and ICH guidelines and their application to study development and monitoring.

During his research career, Erik's interests included the development of new chemotherapeutic studies to target metabolic pathways in cancer. He has a strong background in biochemistry, molecular biology, and toxicology which significantly augments his ability to accomplish any endeavor set in front of him. Erik's graduate work consisted of working with orphan nuclear receptors [specifically nuclear receptor family 4 A1 (NR4A1)] and studying the role of Sp transcription factors as nononcogene-addiction genes. During his doctoral tenure, Erik elucidated previously unknown signaling pathways in triple negative breast cancer, developed and demonstrated the chemotherapeutic potential of methylene-substituted diindolyl methane analogs (c-DIMS) in a multitude of solid tumor malignancies, and mastered many scientific techniques, including cell culture, animal husbandry, CRISPR-Cas9 and lentiviral gene editing, siRNA transient transfection, RT-qPCR, molecular cloning techniques, western blotting, ELISA, Immunoprecipitation, immunofluorescence, Chromatin Immunoprecipitation (ChIP), confocal microscopy, protein purification techniques, DNA site-directed mutagenesis, chromatography (ion exchange ,Gel, Hydrophobic, Reverse Phase, IMAC, and Affinity label), flow cytometry.

Erik also worked as a postdoctoral research fellow at the Cleveland Clinic and continues investigating mechanisms of metabolic resistance in prostate cancer. Prostate cancer is a highly metabolically driven cancer that relies heavily on androgens and the androgen receptor (AR). However advanced prostate cancer involves metabolic pathways that preclude the AR and these pathways need to be elucidated and investigated. Erik has elucidated a role of mTORC1 in AR-negative CRPC and how mTORC1 senses androgens and other steroids as a survival mechanism in treatment of refractory prostate cancer. This research has allowed Erik to apply his current skills and develop new skills in treatment refractory prostate cancer, including HPLC and mass spectrometry. In pursuing this project, Erik has contributed to the field of prostate cancer by exploring novel treatment therapies and demonstrated the therapeutic potential of the mTORC1/PGRMC1 interface as an effective treatment target in AR-negative CRPC.
