Paolo Cassano, M.D., Ph.D., is an Assistant Professor in Psychiatry at the Harvard Medical School and Director of Photobiomodulation at the Massachusetts General Hospital (MGH) Division of Neuropsychiatry and the MGH Depression Clinical and Research Program. He graduated from the MGH-McLean Adult Psychiatry Residency Program in June 2009. Since 2009,he has served as principal investigator (PI) on multiple studies on transcranial photobiomodulation (tPBM) for several neuropsychiatric disorders, such as major depressive disorder (MDD) and generalized anxiety disorder (GAD), sponsored by the Brain and Behavior Research Foundation (NARSAD), the Dupont Warren/Livingston Fellowship from Harvard Medical School, and private companies. These groundbreaking projects - in collaboration with the MGH Wellman Center for Photomedicine - have led to promising results and demonstrated the preliminary efficacy of near-infrared radiation for the treatment of mood disorders and for ameliorating cognition. Considerable press attention stemmed from these studies, with CNN and Washington Post coverage at the national level. He is actively pursuing the identification of biological targets of the effects of tPBM at the MGH Laboratory for Neuropsychiatry and Neuromodulation, where he has been the PI on a pilot study to investigate the impact of tPBM on cerebral blood flow (Diffuse Correlation Spectroscopy - DCS), on brain electrical activity (electroencephalography - EEG), autonomic reactivity (heart rate variability - HRV and skin conductance - SCR), and cognition in healthy subjects. Dr. Cassano is particularly interested in studying tPBM, as a pro-cognitive intervention, in patients with cognitive impairment and has reported with other groups on tPBM to treat chronic traumatic brain injury and Down syndrome and enhance cognition in healthy volunteers. Dr. Cassano's tPBM research is funded by the National Institute of Mental Health (NIMH), the National Institute of Aging (NIA), the Alzheimer Association "Part the Cloud," and the Down Syndrome Research Foundation (UK). In Nov 2016, he co-founded a neurotech company, Niraxx Light Therapeutics Inc., to facilitate the technology transfer from translational research to readily available products for the general public.

Saeed Sadigh-Eteghad, M.Pill, Ph.D., is a principal investigator and an Associate Professor at the Neurosciences Research Center, Tabriz University of Medical Sciences.

Further, he has several projects in progress at various stages of completion and has been a visiting researcher at universities in Denmark and Japan.

Javad Mahmoudi, Ph.D., is an associate professor at the Neurosciences Research Center of Tabriz University of Medical Sciences, where he has been an academic staff member since 2014. He completed his undergraduate studies at Azad University and received his Ph.D. in Pharmacology from the same university. His first area of research is the development of therapeutic strategies for the treatment of neurodegenerative conditions. The second area focuses on the treatments for emotional and cognitive impairments resulting from stressors factors, including spatial restriction and insomnia, as well as noise and heat stresses. Dr. Mahmoudi is a member of the Iranian Neuroscience and the Iranian Physiology and Pharmacology Societies.

Farzin Kamari, M.D., M.P.H., is an accomplished researcher with considerable experience in computational neuroscience, medicine, and public health. He currently serves as a research associate at the Department of Neurophysiology within the Institute of Physiology at the University of Tübingen in Germany, and is additionally affiliated with the International Max Planck Research School for the Mechanisms of Mental Function and Dysfunction, also located in Tübingen, Germany. He earned his Doctor of Medicine (MD) and Master of Public Health (MPH) degrees from the Tabriz University of Medical Sciences in Iran. Dr. Kamari's research interests are focused at the intersection of neuroscience, medicine, and technology, with a particular emphasis on leveraging technical and computational approaches to enhance brain function and mental health.
