Oxford Clinical Research is dedicated to exploring, developing, and publishing evidence related to diet-induced inflammation, medical nutrition therapy, and associated health outcomes.

Evidence will include prospective research on specific disease states, validation of related diagnostic testing,  retrospective outcomes analyses, case studies, clinical reviews, systematic reviews, and meta-analyses related to the full range of clinical conditions associated with diet-induced inflammation.

Oxford’s clinical and technical research team has the credentials and extensive experience designing, conducting, and publishing research in peer-reviewed journals. Oxford Clinical Research is open to scientific collaboration with independent clinicians, researchers, and research entities.

Mark J. Pasula, Ph.D.
Consulting Research Scientist, Technology and Immunophysiology

Dr. Mark J. Pasula is an Immunologist and leading authority on blood testing for adverse food reactions. Dr. Pasula’s primary focus for over 35 years has been on the development of in vitro technologies designed to uncover hidden inflammatory foods and chemicals, as well as dietary strategies designed to improve outcomes when diet is playing a clinical role. Dr. Pasula is the author of multiple US and International patents on food sensitivity testing technologies, including his work over 30 years ago when he wrote the first patent on the original ALCAT test. His latest innovations are the patented Mediator Release Test (MRT®) and MRTIII® instrument, which utilizes a combination of advanced flow cytometry and the patented ribbon impedance method to provide the most reliable, precise, and relevant information regarding food-induced inflammation. Dr. Pasula is a 27-year member of the American College of Allergy Asthma and Immunology.
