Ph.D. 2009 Pharmacology/Toxicology
Background:
I received my Bachelor of Science in Environmental Biology in 2000 and Master of Science in the same major in 2003, both from Nanjing University in China. I came to the United States in 2003 to begin my Ph.D. work in Dr. Andrea Gore’s laboratory.

Research:
My current research investigates the effects of aging on reproductive function in male rats to see whether testosterone and estradiol still play important roles in shaping masculine behavior and physiology in older adulthood. In general, I am looking at altered sex steroid hormone levels with aging along with alterations in the numbers and distribution of steroid hormone receptors. Specifically, I am looking at a negative regulation of the density of androgen receptors in response to declining testosterone and a compensatory up-regulation of the density of estrogen receptors, in the hypothalamus and POA. In addition, I am also seeking to determine whether exogenous testosterone treatment can change the alternation of hormone receptor expression in old male rats. My dissertation research will also include the effects of experience on hormones and hormone receptor expression in the brain.
