Translational Neurogenomics & Alzheimer Biomarkers Laboratory - Yang Lab


Hyun-Sik Yang, MD
Principal Investigator/Assistant Professor of Neurology

Hyun-Sik is a physician-scientist with clinical and scientific expertise in Alzheimer’s disease and related dementias (ADRD). Hyun-Sik spent most of his childhood and young adulthood in South Korea, although he also lived in Fairfax, Virginia when he was 7 and in Lexington, Kentucky when he was 18. After graduating from Seoul National University College of Medicine (MD), Hyun-Sik pursued his internship at Mass General Brigham Salem Hospital, neurology residency at the Mass General Brigham Neurology Residency (class of 2016), and Behavioral Neurology and Neuropsychiatry fellowship at Brigham and Women’s Hospital (BWH). During his residency, fellowship, and early faculty years, Hyun-Sik was mentored by Dr. Reisa A. Sperling (Alzheimer’s disease clinical research) and Dr. Philip L. De Jager (Neurogenomics). Hyun-Sik sees cognitive neurology patients on Monday mornings at BWH and spends the remainder of his work hours in the lab. Outside of work, Hyun-Sik enjoys spending time with his wife, Ga Young Lee (neuroscientist at Harvard Medical School), and their miniature poodle Linus (named after the Peanuts character, the chemist, as well as Linux). Hyun-Sik loves to run along the Charles, so you may spot him running with Linus!

Annie Abruzzo
Medical Student, Harvard Medical School

Annie grew up in New York City and studied biology and history at Swarthmore College. She then spent two years conducting research in the laboratory of Dr. Jeffrey Weiser at the NYU Grossman School of Medicine. She is now in her second year at Harvard Medical School and has been working with the Yang Lab to study biomarkers of Alzheimer disease in aging patient populations.

David Adamowicz, MD, PhD
Geriatric Psychiatry Fellow (MGB/HMS)

David hails from New York, by way of San Diego where he completed his medical degree and residency in Psychiatry. His graduate thesis at the Salk Institute was on Dementia with Lewy bodies, and during residency at UCSD he researched inflammatory biomarkers in people with schizophrenia. His career interests in cognitive decline and neuroinflammation drew him to the Yang Lab, where he is now working on better understanding the interplay between the peripheral immune system and early Alzheimer’s disease. In his spare time, he enjoys soccer, tennis, and traveling.

During her undergrad she worked as a direct care provider at Walker Therapeutic and Educational Programs’ Community Based Acute Care Unit and as a student intern at the Harvard Aging Brain Study at Massachusetts General Hospital. She plans to pursue a PhD in clinical psychology. In her free time, Emily enjoys crocheting and spending time in nature.

Lucas Godwin
Research Assistant

Lucas relocated to Boston from Pittsfield, MA to begin his career in neurodegenerative disease research. He received a B.S. in Psychology from the University of Massachusetts Amherst in 2021, with a concentration in neuroscience and a minor in Biology. During his time at UMass, Lucas assisted research in the Neurocognition and Perception lab, which focused on the processing of linguistic stimuli across a diverse sample population. He now acts as a Research Laboratory Technician at BWH for the Memory and Aging Cohort, as well as for the various studies that fall under the Center for Alzheimer’s Research and Treatment. Lucas plans to pursue further education within the realm of cognitive neuroscience. In his free time, Lucas enjoys film, music, nature, videogames, and spending time with his family.

Courtney Maa, MS
Project Manager

Meet Courtney, a California native who exchanged her flip flops for snow shoes. She earned her BS in Physiology and Metabolism from U.C. Berkeley and pursued an MS in Nutritional Biochemistry at Tufts, specializing in Cognitive Neuroscience. Before making her way to Boston, Courtney ventured into the tech industry, including a stint at Impossible Foods, where her focus was on plant-based meats.

In her research pursuits, Courtney centers her focus on neuroimaging and biochemical studies in cognitive disorders, with a particular emphasis on understanding the intricacies of the brain, especially in conditions like epilepsy and Tourette’s Syndrome. Beyond academia, she aspires to create a positive impact and offer assistance in the lives of children with disabilities.

Off the clock, catch Courtney crafting pottery (Instagram: Maamaacourt), enjoying the local crafts fair, and delving into the world of film photography. On weekends, you’ll spot her volunteering, perfecting her pole, and meandering through the streets of Boston with her faithful four-legged sidekick.

Stephanie Moreno
Research Assistant

Stephanie is one of the research assistants for the Memory and Aging Cohort. Since joining in September of 2022, she has expanded the study to reach Boston’s Spanish-speaking populations. With a focus for increasing diversity in research, she is eager to develop a trusting relationship between MAC and Boston’s underrepresented communities. Stephanie graduated from the University of Texas at Austin with a Bachelor of Science in Biomedical Engineering and a minor in Business Administration. While in school, she worked as a medical tele-scribe for the University of California at San Francisco, a Patient Access Representative at UT Health Austin, and a student associate for COVID-19 vaccination clinics on campus.
