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.

Research Summary:

Inspired by experiences working in healthcare, research from my lab focuses on bridging the biomedical and psychosocial chasm in chronic pain. Chronic pain is a major public health issue with significant functional and financial consequences affecting individuals, the community, and the healthcare system. Even more concerning, the consequences of chronic pain extend beyond disability and decreased quality of life to include an increased incidence of morbidity and mortality. Research investigation and clinical management of chronic pain is difficult due to significant individual variability and the lack of biological indices with which to evaluate risk and protective factors, progression, and treatment response.

Our scientific pursuits are specific to investigating the interactive influences of biological, psychosocial, cognitive, and behavioral factors associated with osteoarthritis and other musculoskeletal chronic pain conditions with an emphasis on stress, aging, health disparities, and resilience. The intentions underlying our investigations are to 1) elucidate biological measures reflecting the stress-related biological burden resulting from chronic pain conditions; 2) delineate resilience and vulnerability factors for prevention and treatment; and 3) identify biobehavioral strategies to optimize chronic pain treatment interventions. The overarching goals of our efforts are to contribute to the research and medical community by improving the understanding of the biological interface of chronic pain and associated stressors, to formulate a clinical composite for assessing and evaluating treatment interventions, and to identify strategies and targets to prevent, reduce or ameliorate chronic pain.

Phone: (352) 294-5167

I am a tenured Associate Professor in the Department of Aging and Geriatric Research in the College of Medicine at the University of Florida. I received my BA from the University of California, Berkeley in 1991 and received my PhD from the University of Tokyo (Tokyo, Japan) in 2005. I then pursued my postdoctoral training in the laboratory of Dr. Tomas Prolla in the Department of Genetics at the University of Wisconsin (2005-2011). I joined the faculty in the Department of Aging and Geriatric Research at the University of Florida as a tenure-track Assistant Professor in June of 2011 and was promoted to tenured Associate Professor in July of 2016.

I have extensive experience (17~ years) in auditory neuroscience, aging and oxidative stress. Up to this point, I have published 47 peer-reviewed research papers and 6 chapter books, and of these, I have several publications in top journals such as Cell, Science, Molecular Cell, PNAS, and Journal of Neuroscience. My research focuses on understanding cochlear aging and gender differences in hearing. Currently, my research is supported by 3 NIH RO1, 1 NIH P30, and American Cancer Society grants.

At the University of Florida, I currently direct six graduate courses: GMS 6486 Biology of Aging (fall/spring/summer), SPA5102 Auditory Anatomy and Physiology (fall), SPA6581 Anatomy and Physiology of Balance (fall), SPA6581 Auditory Pharmacology (summer), and SPA6564 Communication and Aging (spring). I also teach 5 graduate courses as a lecturer, including GMS 6893 Clinical and Translational Science Institute Student Seminar (fall), GMS 6622 Mitochondrial Biology in Aging and Disease (fall), and GMS6070 Sensory Biology (spring). In my courses, I take a student-centered and interactive approach. I encourage students to participate actively.

A large part of my teaching effort is dedicated to mentoring students. I have served or currently serve as a committee member and/or mentor for 8 doctoral students and 18 undergraduate students. Up to this point, five graduate students have completed their PhD program: Mi-Jung Kim (August 2018; Role: Chair), Karessa White (Graduation date: August 2017; Role: Chair), Angela Fulbright, PhD (Graduation date: June 2016; Role: Co-Chair), and Dalian Ding, PhD (Graduation date: February 2015; Role: Co-Chair). I truly enjoy mentoring, interacting with the students in the lab, and sharing my research questions and ideas with them.
