Our laboratory seeks to advance understanding, measurement, prevention, and treatment of functional disabilities in persons with multiple sclerosis (MS), with a particular focus on cognition and memory. We are developing innovative assessment tools to evaluate functional outcomes, and reevaluating and revising old assumptions about cognition and memory to improve treatment. My current NIH R01 is a longitudinal study of risk and protective factors associated with cognitive changes over time, with a focus on potentially modifiable factors that may inform clinical decision making.  As a member of the Corinne Goldsmith Dickinson Center for MS, I have the good fortune to collaborate with and learn from our expert team of MS neurologists. Frequent contact and feedback from our patients has also been essential for identifying clinically important questions with the greatest promise for improving quality of life for the persons striving to accomplish goals and live fully in the context of this disease.

Postdoctoral Fellows

Dr. Lisa Glukhovsky received her Ph.D. in Clinical Psychology (Health Emphasis) from Ferkauf Graduate School at Yeshiva University in 2018. After obtaining a bachelor’s degree in Psychology from Princeton University, she worked as a clinical research coordinator at Massachusetts General Hospital. During her graduate training at Yeshiva University, she gained clinical experience in neuropsychological assessment and interventions with a variety of neurological and other medical populations. Her dissertation examined cognitive-motor dual-task learning in multiple sclerosis. She completed her internship in the Psychiatry Department at the Icahn School of Medicine at Mount Sinai. Her research investigates neuropsychological and psychiatric factors in multiple sclerosis, including executive functions such as multitasking.


Dr. Colleen Marino received her Ph.D. in Clinical Psychology with an emphasis in Neuropsychology from Palo Alto University in 2018. She completed her pre-doctoral internship at Geisinger Medical Center in Danville, PA. Dr. Marino has extensive training in neuropsychological assessment of adult and older adult populations with various psychiatric, neurological, and medical illnesses. She has experience with individual psychotherapy and cognitive rehabilitation in both individual and group formats. Her previous research analyzed neuropsychological assessment tools to better understand cognitive processes underlying performance. Her current research investigates neuropsychiatric factors and coping styles in persons with multiple sclerosis, and utilization of neuropsychological and psychological assessments to inform and create treatment interventions.


Dr. Elizabet Santana received her Psy.D. in Clinical Psychology from Philadelphia College of Osteopathic Medicine (PCOM) where her training focused on Interdisciplinary Care and Clinical Neuropsychology. She completed her pre-doctoral internship at the Department of Veterans Affairs New Jersey Health Care System and has gained extensive neuropsychological assessment and intervention training, in a variety of hospital settings including NYU, Columbia, Bellevue and Kessler Institute for Rehabilitation. Her research interests relate to the impact of sociocultural factors on neuropsychological test performance.


Graduate Students

 Laura Johanson earned a B.S. in Psychology from Florida State University. She is now a Ph.D. student at Teachers College, Columbia University. Her dissertation will investigate contributions of psychological resilience to functional outcomes in persons with MS.




Rosemarie Kurtz earned a B.A. in Psychology from Hunter College. She is now a Ph.D. student at Teachers College, Columbia University. Her dissertation will investigate contributions of sleep disturbance to cognitive function in persons with MS.




Emily Dvorak earned a B.S. in Neuroscience and Psychology from the University of Pittsburgh. She is a Ph.D. student at Teachers College, Columbia University, and currently examining contributions of language to memory in persons with MS.
