Neurons extend axons and form synapses to communicate with distant cells. These unique structures are susceptible to damage from pathological or physiological stresses. Despite their delicate structure, most neurons are not replaced, and so they must be maintained throughout the life of the animal. My long-term research goal is to understand how the nervous system maintains its function and integrity during aging. In particular, my current goal is to identify mechanisms that regulate the location and function of the mitochondria in two key neuronal conditions: injury (the regulation of axon regeneration) and maintenance (preserving normal synaptic function). In response to a range of conditions, neurons transport and position mitochondria at distinct subcellular sites within axons and synapses. Incorrect mitochondrial localization in neurons can result in functional deficits, failure of axon regeneration, and neurodegeneration. However, the mechanisms that regulate mitochondrial localization, and how mitochondrial subcellular localization supports specific neuronal functions are incompletely understood.

My specific goals are:

1) Investigate how aging neurons regulates mitochondrial dynamics in response to local demand and injury; 2) Elucidate how mitochondria control nuclear gene expression in aging neurons; 3) Discover how aging neurons maintain mitochondrial function at synapses.

Over the long term, I believe that these approaches will result in a new understanding of the mechanisms that maintain optimal function of the nervous system during aging by regulating mitochondrial function in aging/stressed neurons. My lab’s findings will provide better insight into novel therapeutic approaches to restore neuronal functional after nerve injury that can cause permanent loss of motility and disability.

Robert Mankowski

Robert Mankowski Ph.D.

Assistant Professor
Phone: (352) 294-5055

Dr. Robert Mankowski is an Assistant Professor at the Department of Aging and Geriatric Research. He obtained his PhD in Exercise Physiology at the Erasmus University Medical Center in Rotterdam, The Netherlands. His translational and team-science research is focused on preserving physical and cardiovascular function in older age. His research spans from investigating the effects of nutritional and exercise interventions on physical and cardiovascular function in moderately functioning older adults, to better understanding the epidemiology and pathobiology of poor long-term physical and cognitive outcomes in older survivors (including race and sex differences) of critical illness, especially sepsis. He aims to translate effective exercise (institution-based and remotely delivered) and nutritional interventions from moderately functioning older adults to poorly functioning older survivors of critical illness. His ultimate goal is to customize exercise and nutritional interventions in populations at risk of frailty, and thus improve quality of life and expand the health span.

Stephanie Wohlgemuth Ph.D.

Research Assistant Professor
Phone: (352) 273-5734

I have been trained and have worked as a comparative physiologist with a focused on metabolic and cellular responses to environmental stress, disease and aging in a variety of species, ranging from marine annelid worms and freshwater fishes to rodents, humans and large mammals. My research expertise spans from whole animal experiments to subcellular organelle isolation and functional assessment to biochemical methodology. My teaching experience includes undergraduate courses in general and developmental biology and graduate courses in muscle physiology, mitochondrial biology, and aging biology. I have worked in leadership positions in physiology laboratories for over 15 years, and have supervised, mentored and trained over 36 undergraduate students, 2 graduate students as direct supervisor and committee chair, as well as 13 graduate students as committee member, and technicians and postdoctoral scientists. I received my Master of Science and Ph.D. Degrees from the Heinrich-Heine-University Düsseldorf, Germany, where I conducted my graduate research in the Institute of Zoophysiology under the supervision of Prof. Dr. Manfred Grieshaber. My area of research included comparative animal physiology and biochemistry, specifically the biochemical and physiological adaptations of marine invertebrate metabolism to environmental stress. I concluded my time at the Heinrich Heine University in Düsseldorf with postdoctoral research in the Institute of Zoophysiology, performing direct and indirect calorimetry on marine invertebrates exposed to hypoxia and hydrogen sulfide, and in the Institute of Genetics (PI Dr. Kimberley Henkle-Duehrsen), investigating the expression of Glutathione-S-Transferase proteins in C. elegans in response to oxidative stress. Subsequently, I continued my studies at the Romberg Tiburon Center for Environmental Studies, San Francisco State University, California, under the mentorship of Dr. Alissa Arp, on cellular responses of marine invertebrates to hydrogen sulfide exposure, using electron microscopy investigations of the body wall musculature of a marine invertebrate to examine hydrogen sulfide-induced formation of autophagic vacuoles. I then joined Dr. Christiaan Leeuwenburgh in the Biology of Aging Laboratory at the University of Florida, studying mitochondrial biology and autophagy in mammalian tissues, and the effects of pro-healthy-aging interventions such as calorie restriction, nutraceuticals and exercise. I expanded my research further and studied the effect of aging and external and endogenous stress on cellular physiology of large mammals, such as equine, cattle and sheep, with specific focus on mitochondrial biology and cellular quality control mechanisms. I have been a co-investigator on several federally funded projects investigating effects of maternal stress on mitochondrial function in the fetal heart and diaphragm using a sheep model (NIH, R21 and R01, PI: Dr. Keller-Wood); effect of mitochondrial function on muscle to meat conversion in different cattle breeds (USDA, PI: Dr. Scheffler), and effect of Resveratrol administration on leg muscle mitochondrial function in elderly humans (NIH, R01, PI: Dr. Anton). Recently, I established the Respirometry Core as part of the Metabolism and Translational Science Core at the Institute on Aging, in UF’s College of Medicine.
