Mara Kuvaldina, PhD
- Neuropsychologist and Researcher in the Lyme and Tick-Borne Diseases Research Center
- Associate Director of the Clinical Trials Network for Lyme and other Tick-borne Diseases
Mara Kuvaldina, PhD, is an Assistant Professor of Medical Psychology and Psychiatry at CUIMC and a Neuropsychologist and Researcher in the Lyme and Tick-Borne Diseases Research Center. She is also Associate Director of the Clinical Trials Network (CTN) for Lyme and other Tick-Borne Diseases.

Her current research focus is neuromodulation (vagus nerve stimulation, transcranial magnetic stimulation, and transcranial direct current stimulation) for chronic inflammatory illnesses and tick-borne diseases. She combines methods of experimental cognitive psychology, applied physics, and psychometry to investigate potential biomarkers and develop an individualized neuromodulation regimen. At the Lyme Center, Mara oversees research activities/clinical trials, data management, and statistical analyses. She joined the faculty at CUIMC in 2021.
Randy Lai, MD

Marianne Gorlyn, PhD
- Clinical Neuropsychologist and Researcher in the Lyme and Tick-Borne Diseases Research Center
Marianne Gorlyn, PhD, is an Assistant Professor of Clinical Psychology in the Department of Psychiatry. Her training and clinical experience encompass assessment of cognitive and behavioral disorders across the life-span, from identifying neurodevelopmental and learning disorders in children and adolescents, to evaluating cognitive problems associated with aging and neurodegenerative diseases in adult and geriatric populations. She has extensive experience in diagnostic and neuropsychological evaluations of psychiatric disorders in children and adults (ADHD, OCD, psychotic disorders, depression and bipolar disorder, anxiety, personality disorders) as well as assessment of cognitive difficulties in infectious diseases (Lyme disease). Dr. Gorlyn has conducted studies and published articles in peer-reviewed journals related to cognitive dysfunction in depression and suicidal behavior.
Krishna Desai, MD, FAAFP
- Integrative Medicine Physician
Krishna Desai, MD, FAAFP, is an Assistant Professor of Medicine with dual board certification in Family and Integrative Medicine. Dr. Desai is a Family Medicine and Integrative Medicine specialist committed to helping children and adults with severe chronic illnesses, as many chronic disorders have underlying common denominators, including imbalances in immune regulation, nutritional deficits, undetected infection, and chronic inflammation.

Andrew J. Dwork, MD
- Professor of Clinical Pathology and Cell Biology in Psychiatry
Andrew Dwork, MD, has a broad range of expertise in neuropathology, having conducted research on hippocampal neurogenesis, the blood brain barrier, and neural epigenetic regulation. Dr. Dwork and his colleague Gorazd Rosoklija, MD, PhD (neurologist and neuropathologist) oversee the post-mortem repository of brain and spinal-cord specimens which contains specimens from generous patients with a history of Lyme disease. Dr Dwork is co-investigator with Dr. Fallon, Dr. Monica Embers, and Dr. Tim Sellati on a post-mortem study of human Lyme disease. Using bright field double immunohistochemical labeling techniques, Dr. Dwork and Dr. Rosoklija examine the post-mortem brains for evidence of microglial activation, macrophages, and altered blood-brain barreir. Next these post-mortem tissues are probed for Borrelia spirochetes and other microbes by our collaborating co-investigators.
