Anthony Joseph Studer

Associate Professor

Dr. Studer improves the efficiency and productivity of cereal crops by optimizing photosynthesis and water use. His research helps develop crops that are resilient to climate change and meet the needs of growers at the regional, national, and international levels.

Primary Disciplines


  • B.S. Biology, Defiance College, 2005.
  • Ph.D. Genetics, University of Wisconsin-Madison, 2011.

Research Interests

  • My lab studies the evolution, regulation, and function of the carbon concentrating mechanism employed by plants for C4 photosynthesis. This process plays an important role in carbon dioxide uptake and transpirational water loss, and thus, has direct implications for photosynthetic and water-use efficiency. Elucidating the genetic control of photosynthesis will enable the manipulation of crops (through both breeding and engineering) to improve productivity and sustainability, which will be vital for food and fuel security in a changing environment.
