Tracy ButlerM.D.
  • Associate Professor of Neurology

Dr. Tracy Butler is a neurologist/neuroscientist with clinical subspecialty training in behavioral neurology and epilepsy and research fellowship training in functional and structural neuroimaging.  She is the medical director of the Brain Health Imaging Institute (BHII) where she oversees subject assessment and clinical trials of therapies and neuroimage biomarkers of aging and neurodegeneration.  Her research uses multimodal positron emission tomorgraphy (PET) and magnetic resonance imaging (MRI) neuroimaging and complementary methods to better understand the biological basis of neuropsychiatric disorders including Alzheimer’s disease, traumatic brain injury, and as normal aging, focusing on pathophysiologic overlap among these conditions such as hormonal dysregulation, neuroinflammation and brain toxic protein (tau and amyloid) accumulation.

Nimmi WickramasuriyaM.D.

Nimmi is a postdoctoral associate in the Tracy Butler lab investigating the role of hormones such as GnRH in neurodegeneration, and helping to conduct a clinical trial testing the GnRH analogue leuprolide as a treatment for Alzheimer’s disease (The LUCINDA trial). She is a graduate of Jagiellonian University School of Medicine with a background in neuroscience. In her free time, she likes to explore the great outdoors through hiking and camping. She also loves to bake Sri Lankan delicacies and share them with friends and family.

Ilker Ilker OzsahinPh.D.
  • Postdoctoral Associate in Radiology

Ilker Ozsahin is a postdoctoral associate in the Tracy Butler lab working on positron emission tomography (PET), computed tomography (CT), and magnetic resonance imaging (MRI) analyses for several diseases including Alzheimer’s disease. He has worked in several different physics areas such as high energy physics, solid-state physics, and medical imaging. At the University of Illinois at Urbana-Champaign, he worked on growth of carbon nanotubes. He received his Ph.D. in medical imaging in Turkey. He has extensive experience with medical imaging devices such as PET, Positron Emission Mammography (PEM), Single Photon Emission Computed Tomography (SPECT), and Compton Camera (CC), including modelling, simulation, characterization, and image reconstruction. He worked at Universidad Autonoma de Barcelona in Spain as a Ph.D. student. In addition to his Ph.D. studies, he worked as a research assistant for six years in the physics department at Cukurova University in Adana, Turkey. After earning his Ph.D., he spent two years at Harvard Medical School and Massachusetts General Hospital as a postdoctoral fellow. He worked on the simulation of a high-performance PET scanner for small animal and breast imaging, and investigated the mechanism of general anesthesia. He served as a visiting postdoctoral fellow at the University of Macau looking into multi-pinhole SPECT collimator design and implementation for brain imaging, as well as cardiac and small animal imaging via adaptive collimators. He is investigating neural network applications for neurological diseases and operational research in healthcare.

Lab Focus

Dr. Tracy Butler is a neurologist/neuroscientist with clinical subspecialty training in behavioral neurology and epilepsy and research fellowship training in functional and structural neuroimaging.  She is the medical director of the Brain Health Imaging Institute (BHII) where she oversees subject assessment and clinical trials of therapies and neuroimage biomarkers of aging and neurodegeneration.  Her research uses multimodal positron emission tomography (PET) and magnetic resonance (MR) neuroimaging and complementary methods to better understand the biological basis of neuropsychiatric disorders including Alzheimer’s disease (AD), traumatic brain injury (TBI), and normal aging.

Dr. Butler’s clinical work is limited to serving as the neurology and neuropsychiatry consultant to NewYork-Presbyterian Behavioral Health Center, diagnosing and treating hospitalized patients with severe psychiatric diseases who can sometimes fall between the cracks of psychiatry and neurology. 

Areas of Investigation

We use PET with novel and Food and Drug Administration (FDA)-approved radiotracers, functional and structural MRI, and complementary neuroimaging and other techniques to improve understanding and treatment of human brain disorders including AD, TBI, epilepsy, depression, and normal agingWe focus on pathophysiologic overlap among these conditions such as hormonal dysregulation, neuroinflammation, and brain toxic protein accumulation and clearance.   

Lab Achievements

  • Launched a multi-site clinical trial, LeUprolide + Cholinesterase Inhibition to reduce Neurologic Decline in Alzheimer’s
    (LUCINDA), during the pandemic. LUCINDA uses innovative hybrid and remote assessment procedures to determine whether a repurposed hormonal medication can improve memory in women with mild cognitive impairment (MCI) or AD.
  • First demonstration using translocator protein (TSPO) PET that human seizures and epilepsy are intrinsically inflammatory, challenging the assumption of prior work that had considered inflammation primarily a result of initiating or seizure-induced neural damage. 
  • Devised a manual tracing protocol based on histology to assess volume of septal nuclei, a small, under-studied basal forebrain structure important for memory and implicated in epilepsy and AD. 
  • First to detect inflammation in the human hypothalamus using PET, demonstrating sex differences potentially relevant to menopause. 
  • First to perform tau PET scanning acutely after traumatic brain injury in order to understand how processes occurring acutely after TBI may contribute to neurodegeneration decades later. 

Research Projects

Traumatic Brain Injury (TBI) is a leading cause of death and disability worldwide and a risk factor for later development of Alzheimer's disease (AD). TBI causes increased axonal production and rapid brain deposition of amyloid, a pathologic hallmark of AD. Persistence of amyloid in the brain after TBI may...

Inflammation is a vital, complex process by which certain cells or tissues identified by the immune system as abnormal (e.g., foreign, damaged or dead) can be repaired or removed to facilitate continued survival of remaining cells and the organism. Excessive or dysregulated inflammation can be harmful,...
