Robert H. Dworkin received his BA from the University of Pennsylvania and his PhD from Harvard University. He is Professor of Anesthesiology and Perioperative Medicine, Neurology, and Psychiatry, Professor in the Center for Health + Technology, and Director of the Anesthesiology Clinical Research Center at the University of Rochester School of Medicine and Dentistry.
Dr. Dworkin is Director of the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership with the U.S. Food and Drug Administration (FDA) and a Special Government Employee of the FDA Center for Drug Evaluation and Research; he previously served as a consultant to and member of the FDA Anesthetic and Life Support Drugs Advisory Committee and as a member of the U.S. Centers for Disease Control and Prevention Herpes Zoster Working Group. He is an Associate Editor of Pain, and a member of the Editorial Boards of Journal of Pain, Canadian Journal of Pain, and Current Pain and Headache Reports. Dr. Dworkin received the American Pain Society’s Wilbert E. Fordyce Clinical Investigator Award in 2005 and John and Emma Bonica Public Service Award in 2014, the Eastern Pain Association’s John J. Bonica Award in 2011 and Raymond Houde Lectureship Award in 2018, the American Academy of Neurology’s Mitchell B. Max Award for Neuropathic Pain in 2015, and the American Academy of Pain Medicine’s Founders Award in 2018.
Dr. Dworkin’s major research interests are (1) methodologic aspects of analgesic clinical trials and (2) treatment and prevention of chronic and acute neuropathic and musculoskeletal pain. The primary focus of his current research involves the identification of factors that increase the assay sensitivity of clinical trials to detect differences between an active and a control or comparison treatment. Dr. Dworkin has also been very interested in the identification of risk factors for the transition from acute to chronic pain. One of the major results of this program of research has been that patients with greater acute pain are more likely to develop chronic pain. This suggests that attenuating acute pain might prevent chronic pain, and an additional focus of his research has involved developing approaches to test this hypothesis.
Dr. Dworkin has authored over 300 journal articles and book chapters, which have been cited over 32,000 times (h index = 85). He has served as a consultant to over 150 pharmaceutical and device companies in the development and evaluation of analgesic and antiviral treatments, and as Director of the Anesthesiology Clinical Research Center, has been the principal investigator for a large number of clinical trials funded by government and industry. These studies have examined treatments for various types of chronic pain—including neuropathic pain conditions, low back pain, cancer pain, fibromyalgia, and osteoarthritis—as well as treatments for acute pain in herpes zoster and acute post-surgical pain.

Research Fellow, University College London
Dr Shafaq Sikandar has more than 10 years of research experience and extensive expertise in using electrophysiology, behaviour, molecular biology and pharmacological assays to study pain in rodents and humans. During her Ph.D. in Pharmacology in University College London, she established new electrophysiological assays for evaluating visceral pain and descending modulation in rodents. In her following first postdoctoral post at University College London, she employed translational approaches to assess pain in rodents and humans in parallel. Her findings showed strong correlations between both species for measures of nociception, thereby substantiating the use of preclinical tests to predict clinical outcomes. These were novel reports of the correlation between evoked neuronal activity in rodent preparations and human perceptual responses to pain.
She was awarded a fellowship to work at UC San Diego, where she studied analgesic mechanisms of botulinum toxin. Her next postdoc was in a molecular genetics lab at the Wolfson Institute of Biomedical Research in University College London, where she has been working on hyperalgesic priming models to study pain plasticity in the nervous system. She is currently an Arthritis Research UK fellow as part of the Centre for Adolescent Rheumatology in London, and continues to use rodent models to identify which subpopulations of sensory neurons mediate the transition of acute to chronic pain.
Founder, Neurotherapia
Dr. Foss received his undergraduate and medical degrees from Brown University, and his training in clinical pharmacology at the University of Chicago. There he led the development of methylnaltrexone, a peripherally active opioid antagonist. This involved the proof of principle trials in pre-clinical models, the first-in-man studies, and subsequent proof of concept trials and studies of the pharmacokinetics and pharmacodynamics in man. Methylnaltrexone was licensed out and approved for clinical use (as Relistor®) in the management of opioid side effects in patients with advanced medical illness.
Subsequently Dr. Foss worked for Adolor, a small biotech company, which was developing alvimopan, another peripherally acting opioid antagonist, which also has been approved for clinical use. Dr. Foss was also responsible for the translational program there that was developing novel analgesics. Dr. Foss was recruited to the Cleveland Clinic to assist in developing the research program in anesthesiology. Dr. Foss began to work with Dr. Mohamed Naguib recently to provide direct support to the development program for the CB2 agonists. They have done extensive research on the mechanisms by which microglial mediated neuroinflammation plays a role in disease and are currently advancing NTRX-07 into human trials for the treatment of neuropathic pain and Alzheimer’s disease. He is a founder of NeuroTherapia Inc.
