Benjamin M. Greenberg, M.D.

Dr. Benjamin Greenberg received his Bachelor’s Degree in the History of Medicine and Science from The Johns Hopkins University. He received a Master of Health Science’s Degree from The Johns Hopkins University School of Public Health. Dr. Greenberg graduated from Baylor College of Medicine with a Medical Degree and was elected to the Alpha Omega Alpha Honor Society. He completed an internship in Internal Medicine at Rush-St. Lukes-Presbyterian Hospital in Chicago, Il and subsequently completed his Neurology Residency at The Johns Hopkins Hospital in Baltimore, Maryland.

After residency, Dr. Greenberg completed a post-doctoral fellowship in neurovirology and immunology at The Johns Hopkins School of Public Health and joined the faculty within the Department of Neurology at The Johns Hopkins School of Medicine. There he served as co-Director of the Transvers Myelitis Center and Director of the Encephalitis program. He moved to UT Southwestern in 2009 and founded the Transverse Myelitis and Neuromyelitis Optica programs as well as the pediatric CONQUER (Collaboration on Neuroimmunology: Question, Understand, Educate, Restore) at Children’s Health Dallas. Currently, Dr. Greenberg serves as a Distinguished Teaching Professor with the Department of Neurology at UT Southwestern and has a secondary appointment within the Department of Pediatrics. He serves as Vice Chair of Translational and Clinical Research for the Department of Neurology. Within the O’Donnell Brain Institute he serves as Director of the Perot Foundation Neurosciences Translational Research Center.

Dr.Greenberg’s research interests are focused on autoimmune conditions that affect the central nervous system. These include multiple sclerosis, myelitis, neuromyelitis optica spectrum disorder, anti-MOG associated disorder, acute disseminated encephalomyelitis, optic neuritis and autoimmune encephalitis. Dr. Greenberg spends a portion of his research time leading efforts to build a comprehensive biobank of samples from patients with these conditions and the rest of his time leading clinical trial efforts for these conditions. He has a particular focus on phase 1, first in human trials. He has served as the PI for several phase 1 trials and as the IND holder for a first in human gene therapy trial.


Morgan McCreary, Ph.D.

Dr. Morgan McCreary is a statistician and Assistant Professor in the Department of Neurology and Neurotherapeutics. He has over five years of experience working in neurological research and currently provides statistical assistance to the Perot Foundation Neuroscience Translational Research Center, having aided over 20 clinician-investigators across several neurology specialties with study design and data analysis, as well as the presentation of results.

Through such collaborations, he has developed an understanding of data elements commonly collected in the neurosciences and he has developed a knowledge of limitations in current statistical methods. This has allowed him to focus on the development of novel statistical approaches tailored to meet these issues.

Dr McCreary’s research interests include analysis in the presence of informative censoring, Bayesian modeling, analysis of latent variables inferred from multivariate measurements, joint modeling of longitudinal and time-to-event data, and analysis of high-dimensional data.

Taylor Hinojo

Taylor Hinojo, M.S., graduated from Texas A&M University in 2015 with a Bachelor’s of Science in Psychology and from UT Dallas in Richardson in 2018 with an Master’s Degree in Applied Cognition and Neuroscience.

Her research experience began with the Texas A&M Department of Visualization where she designed and executed a student-led clinical research project concerning storytelling as a design framework for cognitive support technologies for older adults. The resulting publication received the “Best Paper” award at the International Symposium on Interactive Technology and Aging Populations (IxAP) 2016 conference.

While completing graduate coursework she completed an internship with the Center for Vital Longevity under Dr. Chandramallika Basak where she assisted in the collection and administration of study assessments for a poster presented alongside a doctoral student at the 2018 Armadillo Southwestern Cognition Conference. Having cultivated a passion for neuroscience related research she joined UTSW as a clinical research coordinator and is pursuing interests in novel therapies for multiple sclerosis and neuroimmunology.

The neuroimmunology biorepository was founded by Dr. Greenberg in 2009 and is maintained in collaboration with Dr. Nancy Monson. This effort utilizes an IRB approved protocol to seek permission from patients and controls for the acquisition of data and specimens that can be used in future research projects.

Specimens acquired include blood-based samples, cerebrospinal fluid-based samples, fecal material, urine and in some cases, tissue specimens. The repository processes via standardized protocols to collect serum, plasma, PBMCs, DNA, RNA, CSF supernatant and CSF cells. These samples are stored for future use and can be requested for collaborative projects by emailing Dr. Greenberg or Dr. Monson.

To date, over 7000 sample acquisitions have occurred. Samples from this resource have been used in numerous studies.


Dr. Greenberg’s research includes use of biospecimens to perform biomarker and antibody discovery work in collaboration with Dr. Nancy Monson and the pursuit of novel clinical trials. To date, the efforts surrounding biomarker studies have yielded insights into the immunologic effects of various medical therapies, the identification of novel autoantibodies and processes for analyzing T cell repertoires that could be useful for clinical medicine. Dr. Greenberg has served as PI for over 20 clinical trials including more than 5 phase 1 studies. He has been the IND holder for one trial and served on the international steering committee for multiple studies. Dr. Greenberg has worked to improve the efficiency and robustness for neuroimmunology clinical trials while also working to simplify the process for patients.
