John is a clinical research coordinator who works in both the department of neurology and radiology. He has a MA in psychology from the University of West Georgia and has experience working with a variety of clinical and research populations ranging from adolescents to older adults. For the past several years, he has worked on multiple projects focusing on memory, aging, HIV, and Alzheimer’s disease. Along with recruiting and scheduling research participants, John facilitates study visits by administering neuropsychological tests and coordinating MRI and PET neuroimaging scans.

Brittany M. Nelson

Brittany Nelson is a Clinical Research Coordinator for Dr. Ances. She studied psychology at University of Missouri – St. Louis. She is currently working on the Down Syndrome studies. She was the lead Coordinator on the Exercise Study in the Ances Lab at Washington University and has worked in the Ances Lab since 2014. Brittany has experience working with older adults as well as adolescents. She is the resident REDCap advisor for the lab as well as the website designer and manages the social media accounts. Brittany is also a certified yoga instructor and has a Siamese cat named Yakmaine and a coonhound puppy named Infinity.

Regina L. Thompson, BA

Regina Thompson holds a BA in mathematics from Saint Louis University. She has worked at Washington University in St. Louis since 2002, and joined the Ances Lab in 2014. Regina has extensive experience in project management, performing neuropsychological assessments, and collecting MRI and PET neuroimaging data. She recruits and works with research participants across all age groups on multiple NIH-funded projects. She also coordinates the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) study for the Washington University site and is certified to perform neurocognitive assessments through University of California San Diego. Additionally, she assists with budgets, grant management, and other administrative functions for the Ances Lab.


Neuroimaging Staff

Jeremy F. Strain, PhD

Jeremy is research faculty currently positioned at Washington University in St. Louis. His work has consisted of deciphering anatomical correlates of cognitive change. During his graduate studies at the University of Texas at Dallas, his research revolved around using structural imaging markers to differentiate between variants of dementia (Alzheimer disease and frontotemporal dementia, or FTD) to assist in clinical diagnosis. The bulk of this research was devoted to identifying localized regions of impaired white matter that uniquely coincided with FTD pathology. Additionally, Jeremy transitioned to studying the impact of concussions, but retained an emphasis on brain-behavior relationships.

Patrick H. Luckett, PhD

Patrick has a BS in Applied Mathematics and Statistics, and a PhD in Computer Science from the University of South Alabama. He is interested in Machine Learning, Deep Learning, Data Analysis and Nonlinear Dynamics.

Dimitre N. Tomov

Dimitre is a Washington University graduate with Masters in Electrical Engineering. For more than a decade, he has been involved in modeling of human motor control by the Central Nervous System (CNS). Currently, interested in multivariate modeling of not only what brain regions are involved in some function, but also how impairments and diseases are encoded and modify brain-activity patterns. Specifically, the methods of Representational Similarity Analysis (RSA) coupled with the explosive evolution of machine learning tools, e.g. nilearn, greatly facilitate such investigation as well comparisons across imaging modalities, models, individuals and species.

Kalen Petersen, PhD

Kalen Petersen is a post-doctoral fellow in the Ances lab. He studied biology at the University of Tulsa, and completed his Imaging Science PhD at Vanderbilt University. His work is focused on structure-function relationships in neurological disorders, and he currently studies the effects of HIV on brain aging.

Peter Millar, PhD

Pete is a postdoc in the Ances Lab. He completed his PhD in Psychological & Brain Sciences at Wash U in 2020, working with Dr. Dave Balota. He is interested in using neuroimaging (mainly functional and structural MRI) to study the effects of aging and Alzheimer disease on the brain and how they relate to cognition.

Karin Meeker, PhD

Dr. Karin Meeker is a post-doctoral researcher in the Ances lab. She completed her PhD in Cognitive Neuroscience at Saint Louis University. Her primary goal is to further the understanding of disease pathogenesis and progression of Alzheimer disease (AD) using multimodal methods. Since beginning her position, Karin’s work has largely focused on the utilization of emerging markers of inflammation and neurodegeneration to determine how they are associated and interact with established neuroimaging biomarkers of AD. She is also interested in ethno-racial differences in AD biomarkers and the effects of social determinants of health.

Babatunde Adeyemo

Babatunde Adeyemo is a Neuroimaging Enginner with experience in data acquisition optimization (electro-neurophysiology, rsfMRI), hardware design/development and data analysis (Signal Processing, Statistical Modeling, Machine Learning, Graph Theory and other Non Linear methods). His interests lie in developing methods for subject/group characterization and analysis of Alzheimer’s Disease and other neurodegenerative states.

Omar H Butt, MD, PhD

Omar is a neuro-oncology fellow who works in both the departments of neurology and medicine (division of oncology). He has a MS in molecular biology from Johns Hopkins University and an MD & PhD from the University of Pennsylvania. In 2019, he completed his neurology residency here at Washington University in Saint Louis where he also served as chief resident. Omar has broad interests in multi-modal imaging and the integration of plasma and cerebral spinal fluid into understanding cognition changes in cancer, secondary due to cancer therapies, and in preclinical Alzheimer Disease (AD).

Anna H. Boerwinkle, BS

Anna Boerwinkle began working in the Ances lab as a research technician after graduating from Washington University in 2017 with a B.S. in Systems Science and Engineering. She is interested in neurology and got involved in neuroimaging research to combine this interest with her engineering background. Anna‘s primary research is evaluating neuroinflammation in people living with HIV using PET imaging. She is also responsible for processing the FreeSurfers and PET scans for the HIV projects.

Julie Wisch, PhD

Julie Wisch is a Senior Neuroimaging Engineer in the Ances lab. She studied Mechanical Engineering at the University of Iowa, and completed her PhD in Mechanical Engineering at the University of Missouri. Her research primarily looks at the intersection of real world biomarkers for Alzheimer Disease and neuroimaging data.
