Our Team

Jonathan Rosand, MD, Msc

Jonathan Rosand is a clinician-scientist with expertise in genetics. He oversees all of the research conducted by the group and is the founder of the International Stroke Genetics Consortium. Dr. Rosand has devoted his professional life to the care of patients with the most devastating brain injuries and to reducing the impact of these injuries through his research. He can be found in the hospital, in his laboratory, at the Kistler Research Center or at the Broad Institute. Complementing his research and patient care, Dr. Rosand is a leader, mentor and teacher. At MGH he serves as Chief of the Division of Neurocritical Care and Emergency Neurology, and Medical Director of the Neurosciences Intensive Care Unit. He is Professor of Neurology at Harvard Medical School and an Associate Member of the Broad Institute. The founding director of both the ABMS-accredited vascular neurology training program and the UCNS-accredited neurocritical care training program at Harvard, Dr. Rosand has served as teacher and mentor to a generation of vascular and critical care neurologists.

Chris Anderson, MD, MMSc

Dr. Anderson is a Neurocritical Care physician with research expertise in the medical genetics of complex diseases, specifically ischemic and hemorrhagic stroke. His career research goal is to use computational, genetic, and epidemiologic tools to derive new information about the mechanisms underlying cerebrovascular disease, and to use this information to drive improvement in stroke care through the identification of novel treatment targets and implementation of precision strategies for primary and secondary prevention.

A full list of Dr. Anderson’s publications can be found here.

Katrina Screen

Katrina Screen is Jonathan Rosand’s Office/Project Manager. She serves as the point of contact for Jonathan in both the Rosand Lab and in the Neurosciences Intensive Care Unit. Katrina received her Bachelor’s degree in Communications and Art History at the University of Massachusetts, Amherst and her Master’s in Counseling Psychology from Assumption College.


Whitney Wade


Whitney Wade is Dr. Rosand’s executive assistant and administrative point of contact for the RosAnderson Lab and Mass General’s NeuroICU.  Originally from the Hudson Valley in New York, she is a recent transplant to the Greater Boston area.  She holds a BA in English from Amherst College and a BA in Communication Disorders from SUNY New Paltz.


Sandro Marini, MD

Sandro was born and raised in Pistoia, Italy, where he completed most of his studies, including high school, where his strong interest in science began. He graduated from medical school cum laude with a thesis on the genetics of memory at the University of Florence in 2009. Sandro then started neurology residency at the same University, graduating cum laude in 2015. He was trained in the stroke unit and was responsible for clinical assessment, neuroimaging and neuropsychological evaluation in a study on the risk factors of cognitive disorders in the elderly. More recently, Sandro spent one semester at the University of Geneve, Switzerland, where he dedicated himself to advanced computational neuroimaging, studying functional and structural connectivity measures in vascular cognitive impairment. Finally, Sandro spent six months in Albuquerque (NM) where he had the opportunity to become more familiar with molecular mechanisms of the white matter injuries, commonly seen in elderly patients. Cerebrovascular disease and aging brain are Sandro’s main interests to explore while in the Rosand Lab.


Jaeyoon Chung, PhD.


Andrea Morotti, MD

Andrea spends the majority of his time at the National Neurological Institute C. Mondino in Pavia, Italy serving as a Stroke Attending.   The main focus of his research revolves around ICH expansion and in particular, non-contrast CT markers of hematoma growth in hopes to elucidate the relationship between inflammation, secondary complications and outcome in ICH patients. A long term goal is to create an ICH registry in Pavia, Italy.

Bailey Montgomery, BA


Bailey Montgomery is a Clinical Research Coordinator I for the Rosand Lab. She convenes the International Stroke Genetics Consortium and collaborates with other laboratories to organize genomic data and analyses related to stroke research. Bailey received her Bachelor’s degree from Cornell University in Biological Sciences with a concentration in Human Nutrition and a minor in Business.


Patryk Kubiszewski, BA

Patryk Kubiszewski is a Clinical Research Coordinator for the Rosand Lab as well as the Aging and Brain Health Resource (ABHR) group led by Dr. Biffi. Patryk received his bachelor’s degree in Biological Sciences from Cornell University in 2018. His previous research experience includes work with Drosophila melanogaster studying reproduction and development. As a summer research intern at Weill Medical he did qualitative work on health disparities within the end-stage renal disease patient population.


Jonathan Henry, BA


Jonathan is a Clinical Research Coordinator for the Rosand Lab. He is primarily responsible for DNA extraction and quantification from the biological samples sent to the lab for the various clinical research studies. Jonathan graduated from Western Michigan University with a Bachelor of Science in Biomedical Sciences with minors in Anthropology, Chemistry, Comparative Religion, and Philosophy. He was also a scholarship athlete on Western Michigan University’s football team for 5 years while completing his Bachelor’s degree.


Joel Salinas, M.D., M.B.A.

Joel is a fellow in behavioral neurology and neuropsychiatry with expertise in epidemiology and social determinants of stroke outcomes.  His long-term goal is to develop and deploy strategies to prevent the development of devastating chronic brain disease.  His current work in the lab focuses on investigating predictors and modifiable risk factors of age-related neurologic disease and its sequelae using large epidemiologic cohorts, including the Women’s Health Initiative and the Framingham Heart Study. After graduating from Cornell University, Joel completed medical school at the University of Miami Miller School of Medicine followed by neurology residency at the Massachusetts General Hospital and the Brigham and Women’s Hospital.
