Henry L. Paulson, MD, PhD, is the Lucile Groff Professor of Neurology for Alzheimer’s Disease and Related Disorders in the Department of Neurology at the University of Michigan and interim co-director of the Michigan Neuroscience Institute. Dr. Paulson joined the U-M faculty in 2007, where he directs the Michigan Alzheimer’s Disease Center and formerly co-directed the Protein Folding Disease Initiative. He received his MD and PhD from Yale University in 1990, then completed a neurology residency and neurogenetics/movement disorders fellowships at the University of Pennsylvania. From 1997 to 2007, he was on the faculty at the University of Iowa. Dr. Paulson’s research interests concern the causes and treatment of age-related neurodegenerative diseases, with an emphasis on Alzheimer’s disease and other dementias, hereditary ataxia, and polyglutamine diseases. For his work on repeat expansion diseases and gene silencing as therapy for neurodegenerative disorders, he has been elected as a fellow in both the American Association for the Advancement of Sciences and the National Academy of Medicine. He is most proud of having received, in 2020, NIH’s Landis Outstanding Mentor Award.

Merci Ngozi Best, PhD

Postdoc

mercinb@umich.edu
Merci Ngozi Best, PhD, is a 2023-2024 Basic and Clinical Neuroscience T32 and Michigan Pioneer Fellows Program trainee in the Department of Neurology at the University of Michigan. Dr. Best joined the Paulson laboratory in 2023, where she explores the molecular mechanisms of tau-mediated neurodegeneration. Dr. Best’s research interests concern tauopathy with an emphasis on Alzheimer’s disease, frontotemporal dementia, progressive supranuclear palsy, and chronic traumatic encephalopathy. She earned her BS in Neuroscience from the College of William & Mary in 2017, then completed a PhD in Pharmacology from the University of Virginia School of Medicine in 2023. Her dissertation was titled Breaking Barriers: A Quantitative Analysis of Axon Initial Segment Damage in Neurodegenerative Diseases. Dr. Best aims to deliver a mechanistic understanding of the relationship between tauopathy and perturbations in neuronal cytoarchitecture, employing human disease tissue, human stem cell lines, and brain organoids.

Anushka Chakravorty, PhD

Postdoc

anushkc@umich.edu
Anushka is a postdoctoral researcher in the Paulson lab. She earned her PhD from JNCASR, India, where she investigated novel regulatory mechanisms controlling the autophagy pathway in neurons. In 2024, she joined the Paulson lab, where her research focuses on developing CRISPR-based therapeutic strategies for repeat expansion disorders. She is also interested in exploring the role of polyQ repeats in the biology of Ataxin-3 and its dysregulation in SCA3 using human stem cells and organoids. Outside of her research, Anushka enjoys yoga, Indian classical music, and exploring diverse cuisines.

Harihar Milaganur Mohan, MS

Graduate Student

harimm@umich.edu
Hari is a PhD candidate in the Cellular and Molecular Biology Program. He obtained his undergraduate degree from SASTRA University (India) and his Master’s from the University of Michigan, where he worked on alpha-1-antitrypsin deficiency. At the Paulson lab, he seeks to understand the molecular mechanisms of ubiquilin biology beyond proteasomal shuttling, in particular during cellular stress. Outside of lab, Hari enjoys sketching, running and playing soccer.

Rae Powers, BS

Graduate Student

raepow@umich.edu
Rae is a PhD pre-candidate in the Cellular and Molecular Biology Program. She received her BS from Gettysburg College where she majored in Biochemistry and Molecular Biology and minored in Neuroscience. She conducted translational cancer research during two summer internships at Janssen Pharmaceutical Companies of Johnson & Johnson. After graduating, Rae worked as a Research Technologist at Johns Hopkins University School of Medicine for a few years and studied epigenetic alterations relevant to cancer development during aging. After joining the Paulson Lab in March of 2022, she has been using stem cells and CNS organoids derived from patients with Huntington’s disease (HD) and spinocerebellar ataxia type 3 (SCA3) to uncover the molecular mechanisms of CAG repeat expansion diseases. Her hobbies include skiing, backpacking, climbing, and sailing.

Niki Grotewold, BS

MD/PhD Student

ngrotewo@med.umich.edu
Niki Grotewold is an MD-PhD student in the Cellular and Molecular Biology Program. He majored in Biochemistry at the Ohio State University and is interested in studying neurodegenerative diseases. In the Paulson lab he is studying the role of ubiquilins in Huntington's disease and frontaltemporal dementia (FTD). Outside of the lab, he enjoys playing soccer, piano, and traveling.

Asuman "Ilkim" Erturk, DVM

Research Lab Specialist Senior

asumane@umich.edu
llkim Erturk received her DVM from Istanbul University in 2001. She an extensive background in longevity studies, particularly involving mouse models of aging. She wants to expand her knowledge in the field of neurodegenerative diseases. Her enthusiasm for learning and her hands-on experience in performing surgery stems from her experience as an animal veterinarian and extends to mouse models of neurodegeneration. She manages the Paulson lab /Sharkey lab and Srinivasan labs together, her managerial skills and knowledge of safety and lab procedures ensure that laboratories operate smoothly. Outside of the lab, Dr. Erturk has a profound passion for the arts and traveling. She is an avid collector of Japanese art and actively serves on the FAAC board at the Detroit Institute of Arts. Her multifaceted interests and dedication to both science and the arts make her a well-rounded.

Don Seyfried, MS

Research Technician Senior

dose@umich.edu
Don received his Master’s in Neuroscience from the University at Buffalo, working on how the Unfolded protein response (UPR) can cause neurodegeneration in the diabetic retina. Afterwards, he joined AxoSim Inc. a biotech company that focuses on developing in-vitro models of the human brain to be used for evaluating novel therapies for neurological disease. He is excited to add this perspective to the Paulson Lab’s already-established brain organoid model. In his free time, he looks after his very hungry group of treefrogs.

Michael Bonomo, MS

Research Lab Specialist

bonomom@umich.edu
Michael Bonomo is a Research Specialist Intermediate in the Paulson Laboratory. He recently obtained his M.S. from Eastern Michigan University where he instructed a freshman cell and molecular biology course. Previously, Michael has worked as a metallurgical chemist, a wildlife handler and educator and later, a plant health specialist. In the Paulson Lab Michael is interested in combining his passion for studying living systems and cell and molecular biology by working with neurodegenerative disease mouse models. In his free time Michael loves kayaking, fishing, camping, and exercising.
