barrientos-195x260

Antoni Barrientos, PhD

Dr. Barrientos is interested in the basic processes underlying the biogenesis of the mitochondrial respiratory chain (MRC) and how they bear on human neuromuscular and neurodegenerative disorders and during the aging process. We use yeast and mammalian cell culture models for our research
Three of the research lines in the lab involve:
1- We intend to delineate the assembly process of the enzymes composing the MRC, with special emphasis in cytochrome c oxidase (COX). COX deficiency is the most frequent cause of mitochondrial neuromyopathies in humans and has been shown to decline with age.
2- We are interested in the creation of yeast and neuronal models of age-related human neurodegenerative disorders (including Huntington’s disease and Parkinson’s disease). This will help us study the alterations in mitochondrial physiology that could be essential for the pathogenic mechanism of such disorders.
3- We have created novel yeast models of chronological aging that are being used to explore the role of mitochondrial function in the aging-disease relationship. The results obtained are being validated in mammalian neuronal aging models.

Joyce-Gomes-Osman

Joyce Gomes-Osman, P.T., Ph.D.

Joyce is a physical therapist, health coach and neuroscientist. After completing her physical therapy degree in her native country of Brazil, she obtained her Ph.D. at the University of Miami Miller School of Medicine, and a postdoctoral fellowship at Harvard Medical School. As a rehabilitation neuroscientist, Dr. Gomes-Osman is driven to answer questions that can impact people’s ability to live more functional and independent lives. Before joining Linus, Dr. Gomes-Osman worked as an Assistant Professor at the Departments of Physical Therapy and Neurology at University of Miami, dividing her time between teaching neurophysiology, and carrying out studies to disentangle the complex relationships between physical exercise, brain health and postural control in older adults and individuals with various neurological conditions. An important focus of Dr. Gomes-Osman’s work is focused on better understanding how we can optimize lifestyle interventions to promote better brain health for individuals who are aging. This interest in brain health has stemmed both from scientific curiosity, and from experiencing the reality behind the statistics, witnessing memory deficits as a family member. She is deeply committed to characterizing the “active ingredients” of physical exercise as it pertains to maintaining mental sharpness in aging adults. Joyce is very excited to join Linus and work to achieve her long-term goal of delineating individualized exercise and lifestyle programs to promote better brain health in aging. Her work has been featured in many media outlets including The Boston Globe, The Times, CBS News, Medscape, Healthline, and was featured in the Time Magazine article “Here’s How Much Exercise You Need to Keep Your Brain Healthy.” On her free time, Joyce enjoys spending time with her 2.5 year old son Danilo, her husband Brian and their golden doodle puppy Samba. She is passionate about cooking and growing tropical plants, including exotic orchids from all over the world.

David Loewenstein, PhD, ABPP/CN

Dr. David Loewenstein is the Director of the Center for Cognitive Neuroscience and Aging and Professor of Psychiatry and Behavioral Sciences for the University of Miami School of Medicine. He is a board-certified clinical neuropsychologist and Director of the Division of Neuropsychology. Previously, Dr. Loewenstein served as Director of Neuropsychology Laboratories and Research at Mount Sinai Medical Center in Miami Beach, FL and Chief of Psychology for Jackson Memorial Hospital. He has been continuously funded by the National Institutes of Health at the University of Miami for more than 25 years and has brought in over 21 million dollars in Federal and State grants. His work is regularly published in top scientific journals and is considered cutting-edge. Dr. Loewenstein’s laboratory has a long history in the development of innovative cognitive and neuropsychological instruments and examining their relationship with biomarkers of brain health (amyloid and tau PET scans and CSF, MRI, fMRI). Dr. Loewenstein developed the first scale for the direct assessment of functional capacity in Alzheimer’s disease which has been translated into numerous languages. Most recently, Dr. Loewenstein and associates developed the Loewenstein and Acevedo Scales for Semantic Interference and Learning (LASSI-L), a cognitive stress test to address the concern that current neuropsychological measures may not capture the earliest stage of Alzheimer’s disease. The LASSI-L is a sensitive marker of the early manifestations of AD and has been increasingly adapted by other laboratories.

blanton-195x260

Susan Halloran Blanton, PhD

Dr. Blanton received her PhD in Human Genetics from Virginia Commonwealth University/Medical College of Virginia. She obtained post-doctoral training in Biostatistics (University of Pittsburgh) and Population Oncology (Fox Chase Cancer Center). Her primary research has focused on the mapping of genes for Mendelian and complex diseases; she has been instrumental in studies identifying over twenty genes/loci for Mendelian disorders. Stroke and the underlying genetics of its risk factors, deafness, retinal diseases, skeletal dysplasias, cleft lip/palate, and clubfoot are among the diseases which she currently studies. She collaborates with Drs. Sacco, Wright and Rundek to identify genetic factors influencing white matter and cognition and their relation to ageing. In addition, she has been involved in developing and implementing genetic education materials for Federal and appellate level judges and science writers in an ELSI sponsored project. Dr. Blanton is the Executive Director of the Hussman Institute for Human Genomics as well as the Associate Director of Communications and Compliance. She is an Associate Professor in the Dr. John T. Macdonald Foundation Department of Human Genetics.

Roger McIntosh

Roger McIntosh, PhD

Dr. McIntosh’s work broadly examines risk factors associated with accelerated cognitive aging in chronic disease populations. His previous work addressed how cognitive-emotional impairment impacts disease management amongst persons living with the Human Immunodeficiency Virus (HIV). Currently, Dr. McIntosh utilizes functional magnetic resonance imaging (fMRI) to focus on how cardiovascular disease risk factors, inflammatory-immune biomarkers and psychological distress impact the neural circuitry underpinning cognitive processes such as executive function, episodic memory and interoceptive awareness. Dr. McIntosh was recently awarded a National Institutes of Health (NHLBI) K01 award to conduct an fMRI study examining how HIV impacts the neural substrates underpinning cardio-autonomic regulation amongst HIV+ individuals at risk for developing hypertension.
