Dr. Schumaker and her Research

Schumaker Lab

   
Background and Interests
 
Karen Schumaker received a Ph.D. in Botany from the University of Maryland. She also has a Master's degree in Agronomy and Plant Breeding from Oregon State University and a Bachelor's degree in Plant Sciences from the University of California, Davis. Here at the University of Arizona she teaches Plant Growth and Development for undergraduate and graduate students and the physiology component of Core Concepts in Plant Biology for graduate students. Her research interests include understanding how specificity is achieved during calcium-mediated growth and development, identifying mechanisms controlling plant adaptation to salt stress and identifying transcriptional regulatory networks controlling female gametophyte development.
