Kathy Barton
Staff Scientist, Carnegie Institution, Department of Plant Biology
Professor by Courtesy, Biological Sciences, Stanford University

Research interests: Determining how stem cells in the plant meristem make leaves. The role of post-transcriptional regulatory mechanisms in plant development.

Research topics: development, gene regulation, genomics, genetics

Species studied: Arabidopsis thaliana


Dominique Bergmann
Assistant Professor, Biological Sciences, Stanford University

Research interests: Cell fate specification during plant development, primarily focused on the asymmetric divisions that generate stomata in the leaf epidermis and lateral roots from the pericycle. We currently study the local cell--cell interactions that orient cell divisions and mechanisms by which cells polarize their divisions, but are also interested in understanding how cells integrate local signals with long-range environmental signals to optimize stomatal pattern and density for photosynthetic efficiency and plant growth.

Research topics: development, cell biology, signal transduction, genetics, genomics

Species studied: Arabidopsis thaliana and other species as appropriate


Devaki Bhaya
Adjunct Staff Scientist, Carnegie Institution, Department of Plant Biology

Research interests: Molecular basis of phototaxis in cyanobacteria; signal transduction networks; type IV pilus mediated motility; comparative and functional genomics in cyanobacteria

Research topics: genetics, genomics, gene regulation, evolution, photosynthesis, environment

Species studied: Synechocystis sp., Anabaena sp., Synechococcus sp.


Winslow Briggs
Emeritus Director, Carnegie Institution, Department of Plant Biology

Research interests: Physical and chemical properties of phytochrome and blue light photoreceptors for the photomorphogenic processes. Emphasis is on interactions of the photoreceptors with membranes, physiological, biochemical, and molecular consequences of photoreceptor excitation, and plant growth hormone physiology and biochemistry.

Research topics: biochemistry, cell biology, genetics, molecular biology, photomorphogenesis, signal transduction

Species studied: Arabidopsis thaliana and others as appropriate.
