Howard Feldman, MD, FRCP
Howard Feldman, MD, FRCP (C) was appointed Director of the Alzheimer’s Disease Cooperative Study (ADCS) in April 2016. He is a clinical neurologist and Professor of Neurosciences at the University of California, San Diego (UCSD). Dr. Feldman came to the ADCS after serving as the Executive Associate Dean for Research at the University of British Columbia (UBC) as well as the Director of the Alzheimer’s and Related Disorders Clinic at UBC. He continues to hold an appointment as an Affiliate Professor with UBC.
Dr. Feldman has made vital contributions in scientific discoveries and clinical research studies focused on aging, mild cognitive impairment/Alzheimer’s disease (AD), frontotemporal dementia (FTD) and diagnostic/therapeutic trials. He contributed to the discoveries of the progranulin (Nature 2006) and C9ORF72 (Neuron 2011) genetic mutations which cause FTD and FTD with motor neuron disease. He was involved in the development of important novel criteria for Alzheimer’s disease that re-conceptualize the disease and could lead potentially to earlier and more successful interventions (Lancet Neurology 2007, 2011, 2014). Dr. Feldman has led a number of international clinical trials in AD resulting in important original data and informing care across the continuum of the disease.
His career contributions have been profiled in Lancet Neurology in 2007. In 2014 he was named by Thomson Reuters as a ‘highly cited’ neuroscientist and among ‘the world’s most influential scientific minds.’ He has been appointed as Fellow of the Canadian Academy of Health Sciences and the American Academy of Neurology in 2008. He has served as inaugural Fisher Family and Alzheimer Society of British Columbia Endowed Professorship for Research in Alzheimer’s Disease.
From 2009-2011, Dr. Feldman took a leave from his academic appointment at UBC to take on a senior leadership role as therapeutic area head for neuroscience global clinical research at Bristol-Myers Squibb, where his research focused on developing novel pharmaceutical therapies for neurodegenerative and other neurological/psychiatric disorders.
James B. Brewer, MD, PhD
Dr. Brewer received his graduate and medical training at Stanford University and his neurology residency training at Johns Hopkins University. He joined the Department of Neurosciences in 2004, in a joint recruitment of the Departments of Neurosciences and Radiology, and is a leading investigator at the interdisciplinary Multimodal Imaging Laboratory.
Dr. Brewer’s primary research interest is human memory. He uses functional and structural magnetic resonance imaging (MRI) to study memory processes in volunteers with healthy memory and in patients with memory impairment, such as cases caused by Alzheimer’s disease (AD). This research focuses on the medial temporal lobe (MTL) of the brain, which shows selective damage early in the course of AD. The overarching aim of the work is to better understand the memory function of distinct MTL substructures and the nature of the interaction between those substructures and other brain regions.
Dr. Brewer was one of the first researchers to show that functional MRI (fMRI) can identify distinct activations within the MTL. He and colleagues were the first to use the technique of event-related fMRI to identify brain activity that is directly related to the process of forming memories.
In addition, Dr. Brewer teaches neurosciences and neurology to graduate students, medical students, and residents. He participates as a lecturer in courses on fMRI and memory, assists in neuroanatomy instruction for medical students, and is an active participant in the Neurosciences Graduate Program. He is Co-Director of the UCSD Neurology Residents’ Clinic at the VA San Diego Healthcare System, where he advises and mentors neurology residents in clinical neurology. He is an attending physician at the UCSD and VA Medical Centers. In addition to his university service, Dr. Brewer is an ad hoc reviewer for several journals, including Neurology, Trends in Neurosciences, and Hippocampus.
