About Shinichi Someya

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.
