Curriculum Vitae
Biographical Statement:

  • Dr. Zhenglong Gu received his Bachelors of Science degree in Biochemistry and Molecular Biology from Peking University in 1998, and his PhD degree in Ecology and Evolution in 2003 from University of Chicago. He conducted his postdoctoral research at Stanford Genome and Technology Center from 2004 to 2006. He became an Assistant Professor in the Division of Nutritional Sciences at Cornell University in 2006.
  • Dr. Gu's laboratory uses a combination of computational and experimental approaches to understand the structure of metabolic networks and how these have been shaped over evolutionary time by selective pressures, such as those imposed by nutrient constraints. Much of the effort is devoted to understanding these issues in Saccharomyces cerevisiae, because of its simplicity, rapid growth and the availability of robust experimental and computational tools. Specific interests include evolution of aerobic fermentation in yeast and its implication in ethanol production and cancer physiology, duplicate gene regulation and evolution of antagonistic pleiotropy, genetic and evolution of complex life traits in pathogenic fungi. His laboratory also has interests in using computational and experimental approach to investigate function, evolution and diseases relevance for mitochondria.

Teaching and Advising Statement:
  • Teaching: I believe the primary goal of teaching at a prestigious academic institution is to provide knowledge and instruction to students, encourage them to fulfill their potential and challenge them to perform above their own expectations. 
  • Advisory: The primary goals of an advisor are to serve as a mentor to students, and assist them in their pursuit of meaningful educational programs, which is important for fulfilling their life goals. The positive experience for students during their years at Cornell will have a great impact on their future. I have been fortunate to serve as an advisor to many students, and I have performed this role with care.
