Orett Burke Jr.

Outreach Research Assistant II


Orett joined the Center for Alzheimer Research and Treatment (CART) at the Brigham and Women’s Hospital during the summer of 2017 after graduating and studying biology at the University of Massachusetts Amherst. He was interested in learning more about Alzheimer’s after his grandmother became bedridden due to this disease. For two years, he worked as a clinical and outreach research assistant which involved administering electrocardiograms (ECGs), drawing blood, taking vital signs and many other tasks. Also, he participated or presented at outreach events in the Boston area to help educate underserved communities about this disease and preventative measures. In June of 2019, he wanted to spend more time in the community, so in June of 2019, he was promoted to outreach research assistant II.  In his current role, he presents more in underserved communities, conducts a research project which will help clinicians find more patients that could be eligible for research, and other tasks such as program development. With this experience, he intends to use everything he has learned about medicine, how to communicate with participants and the importance of listening to people’s concerns in the community as he plans on attending medical school.



Fun Fact: He played basketball collegiately at Dickinson College (Div. III) and his team made it to the Elite 8 in 2013.  Also, he is notoriously known for only eating the same food item at each restaurant, in his defense, he often says, “Why disappoint yourself?”

Jasmeer Chhatwal, M.D., Ph.D., MMSc

Attending physician and scientist, Department of Neurology, Massachusetts General Hospital
Assistant in Neurology, Harvard Medical School.  

Jasmeer Chhatwal is a research-oriented neurologist who is fascinated by the complex neurobiology that underlies human memory and the manner in which advanced age and neurodegenerative disease both diminish our capacity to form memories and recall information. He studied biology and philosophy at Yale University, neuroscience and medicine at Emory University, and clinical investigation at Harvard Medical School. Dr. Chhatwal has been based at Massachusetts General and Brigham and Women’s Hospitals since 2009, when he started as a resident in Adult Neurology. He is now an attending physician and scientist in the MGH Department of Neurology, and an assistant in neurology at Harvard Medical School. 

Dr. Chhatwal’s central interest is to deepen our understanding of how neurodegenerative diseases degrade cognitive neural networks and to apply this knowledge to help patients with memory disorders. His current research uses multi-modal neuroimaging (PET, functional and structural MRI), pharmacology, and genetics to better understand what differentiates individuals aging normally from those early on the pathway to neuro degeneration and severe cognitive decline.  He has a particular interest in genetic susceptibility to Alzheimer’s disease, and serves as the MGH/BWH site leader for the Dominantly Inherited Alzheimer’s Network (please see www.dian-info.org for more information).

Jessica Gerber MS, LAc

Jess joined MGH Neurology as Dr. Steven Arnold’s Research Program Manager. She oversees protocol start-up activities for studies primarily focused on the identification and prevention of Alzheimer’s Disease. In addition, Jess is the Program Manager for the newly formed MGH Interdisciplinary Brain Center. The IBC is both a state of the art Clinical and Translational Research Unit and an academic collaboration between the MGH Departments of Neurology, Psychiatry and MGH Martinos Center for Biomedical Imaging. Jess is also helping to develop a common assessment that all subjects participating in research at the CTRU could take part in; eventually she will help organize access to this data for researchers from all over the globe.

Jess’s original education and professional development were in the field of manufacturing engineering; however, all along she had an interest in integrative health and decided to pursue a career as an acupuncturist. After owning a clinic in which she saw 60+ patients per week, she transitioned over to the MGH Martinos Center and got her start in research as a research acupuncturist. Her role was to provide acupuncture therapy services to subjects enrolled in ongoing clinical and basic research studies both inside and outside the MRI scanner; and she continues to consult on NIH Program Project Grants and other clinical trials for the Martinos Center as needed.  Jess also sees acupuncture patients at the BWH Pain Center.

Jess looks forward to continued collaborations with researchers of all backgrounds to further support the MGH IBC mission which is to facilitate and synergize research for brain disorders.
