I graduated from Virginia Tech in 2011 with a degree in biochemistry and have been working at the NIH for the past year in the Laboratory of Population Genetics. I am a first year graduate students in Biochemistry and Molecular Genetics and have joined the Yan Laboratory for my first rotation. I am interested in the role of mitochondria in cell function specifically in disease occurrence and progression. I am looking forward to an enlightening and productive Ph.D. training in the Yan Lab.

I am a 3rd-year PhD student from East China Normal University (ECNU) in Shanghai, China. My major is kinesology, and my research interest is exercise-induced adaption and mitochondrial regulation. Thanks to the sponsorship of China Scholarship Council (CSC), I joined in the Yan Lab in September of 2015 to condut my PhD research on molecular mechanisms of exercise-induced adaptation in skeletal muscle for 2 years. I appreciate this research opportunity and will enjoy my stay here in Charlottesville.

I am a first year MSTP student rotating in the Yan Lab for the summer of 2017. I graduated from the University of Wisconsin in 2017 with degrees in Biochemistry and Neurobiology. I hope to apply my dual MD/PhD training to the promotion of health in addition to the prevention of disease. With this goal in sight, I am looking forward to studying cardiac muscle at the molecular level in response to exercise training in the Yan Lab. Outside of academia, I enjoy trail running, telemark skiing, and ultimate Frisbee.

A double wahoo, I have been in Charlottesville the past six years, and just completed my masterís degree in exercise physiology. I am excited to explore the mechanisms behind how exercise stimulates adaptations in a variety of organs and tissues that lead to a host of health benefits. I grew up in DC, so I am a diehard DC sports fan. I am a casual golfer and an avid runner, competing in local road races here in Charlottesville.

As a rising senior at Washington and Lee University, I am majoring in Sociology & Anthropology major and minoring in Dance. In the coming year, I intend to complete my pre-medical track and aspire to attend medical school. For over four years I have trained in MMA fighting, helped others reach their fitness goals in group fitness classes, and have participated in multiple Spartan Races. Having this background in training in addition to clinical experience, I was ready to see more. This summer, I have the honor of following and assisting a PhD student, Di Cui, as she makes ground breaking discoveries through her kinesiology research. Serving as her right hand (wo)man has allowed me the opportunity to see the true science behind excersize and discover the marvelous benefits of physical activity through analyzing data.

I completed my PhD in Human Bioenergetics at Colorado State University.  My research was focused on potential mechanism(s) responsible for slowed aging.  It is theorized that an accumulation in damaged proteins, particularly of mitochondrial proteins, disrupts cellular proteostasis and propagates the development of the aging phenotype. Using novel stable isotope techniques, a major goal of my doctoral work was determining that an increase in proteostatic mechanisms across multiple tissues was a shared characteristic of multiple rodent models of slowed aging.

Exercise may help promote mitochondrial proteostasis in skeletal muscle through regulation of both protein biogenesis and degradation (i.e. mitophagy).  How mitochondria locally sense and subsequently propagate the appropriate response to exercise is not well understood.  My projects explore these potential mechanisms and how chronic metabolic diseases may alter proteostatic outcomes in skeletal muscle.
