Heather Bimonte-Nelson, PhD

Behavioral Neuroscience Program Professor
ASU School of Life Sciences

For over two decades Dr. Bimonte-Nelson has been conducting preclinical evaluations of multiple domains of cognitive function as related to aging, with a special focus on transitional and surgical menopause, and exogenous and endogenous hormone exposures across the lifespan. She has published over 70 peer reviewed manuscripts evaluating hormone effects on the brain and behavior from early development until old age, with her earlier work showing that female brain organization is actively feminized by estrogens, and that estrogen exposures across the lifespan impact the female phenotype. She has expertise in behavioral measurements and related neurobiological assays, especially as associated with aging and hormone milieu.

Dr. Brewer’s interests include behavioral and electrophysiological recording of memory processes, prospective memory, source memory, recognition memory, individual differences in working memory, and emotional effects on memory. Additionally, he is interested in statistical models of memory and other statistical applications within psychology.

 



 

Paul Coleman, PhD

Research Professor
ASU-Banner Neurodegenerative Disease Research Center

Paul Coleman attended elementary, middle and high school at Friends Seminary in New York and then obtained an A.B. degree magna cum laude from Tufts. He next earned a Ph.D. in physiological psychology from the University of Rochester. After military service at the Army Medical Research Laboratory, Ft. Knox, KY, he completed a fellowship at Johns Hopkins School of Medicine. He spent several decades as a Full Professor at the University of Rochester School of Medicine during which time he was Director of the University of Rochester Medical Center Alzheimer’s Disease Center and Director of an NIH Training Program in Neurobiology of Aging. During this time, he also spent time at Cold Spring Harbor Laboratory. While at the University of Rochester he trained a number of students who are now Professors throughout the United States and Europe. In 2007 he moved his laboratory to the Banner Sun Health Research Institute. In 2015 he moved his laboratory to the Neurodegenerative Disease Research Center at the Biodesign Institute, Arizona State University.

Ever since Dr. Coleman's first publication on Alzheimer's disease that indicated continuing neuronal plasticity in the aging human brain and loss of this plasticity in Alzheimer's disease (Science, 1979) his work has focused on differentiating changes in the brain in Alzheimer's disease from changes related to normal, non-demented ageing. His initial studies in this area were based on quantitative Golgi studies of dendritic extent in human and rodent brains. Feeling a need to be able to competently expand into studies using molecular biology, he spent much of two summers at Cold Spring Harbor Laboratories learning molecular biology and molecular biology methods. One of these summers resulted in the first publication (with Jim Eberwine in PNAS) of a method of profiling gene expression in single identified neurons. Most recently, Dr. Coleman’s work has expanded into the realm of epigenetics. This work is successfully demonstrating that reduced transport of epigenetic molecules from the cytoplasm into the cell nucleus is an early key event in the cellular pathology of Alzheimer's disease. This inability of epigenetic molecules to translocate to the nucleus, where they should be, has consequences for chromatin structure and consequently, the massive changes in gene expression seen in the AD brain. In addition, the aberrant cytoplasmic localization of epigenetic molecules leads to interactions with transport mechanisms in axons and dendrites, to interactions with mitochondria and to other interactions leading to the pathophysiology of Alzheimer's disease. Dr. Coleman has received a number of awards for his work, including a Leadership and Excellence in Alzheimer’s Disease Award from the National Institutes of Health (one of 12 ever awarded) and a Pioneer Award from the National Alzheimer’s Association.

Geidy Serrano, PhD

Neuroanatomist
Brain and Body Donation Program
Banner Sun Health Research Institute

In 2000 Dr. Serrano graduated with honors from the University of Puerto Rico, Cayey Campus, and worked for a year in a biochemistry laboratory at the University of Florida. In 2006 she completed her doctoral degree in Anatomy at the University of Puerto Rico, Medical Science Campus, where she developed scientific skills, not only technical but also analytical. While pursuing her doctoral degree, she received the Minority in Neuroscience Fellowship from the Society of Neuroscience and had the honor to do an Internship at the Marine Biological Laboratory at Woods Whole, MA. In 2007 she started a postdoctoral appointment at Emory University’s School of Medicine and received a National Research Service Award Training Grant (F32-NINDS). After three years of postdoctoral training, she joined the Brain and Body Donation program at Banner Sun Health Research, Sun City, Arizona. Her work allows her to contribute to brain and biospecimen research that pursues the understanding of neurological disorders around the world.

Dr. Serrano’s most recent research contributions are in neurodegeneration of aging in humans and gender differences. Her most recent publication suggests that, when affected by Alzheimer’s Disease, females progress more often to severe cognitive dysfunction, due to more severe neurofibrillary degeneration and greater loss of brain parenchyma. Other relevant work involved the search for a peripheral biopsy for Parkinson Disease and a feasibility study of frontal cortex needle core biopsy for detection of characteristic proteinopathies of neurodegenerative diseases.
