Barton Lab

The Barton lab studies how plants make new leaves and stems from clusters of undifferentiated cells located at the tips of branches. These clusters of cells are called apical meristems and contain within them a small number of self renewing stem cells. Within the meristem, the decision as to what type of cell a cell ultimately becomes is controlled by a network of transcription factors. Recently, our studies have identified points where environmental signals interact with this intrinsic genetic program to modify growth. We hypothesize this interaction serves to coordinate the production of leaves and stems with the availability of water and nutrients. The understanding of plant growth and development gained from these studies establishes a foundation that can be used to breed resilient plants, thereby increasing food security in the face of a changing environment.

Lab Members

Samuel Hokin (Senior Computational Scientist)
Sam received his Ph.D. in plasma physics from MIT, did his post-doc at the Kurchatov Institute in Moscow, and spent the first 10 years of his career on the faculty of the UW-Madison and then KTH in Stockholm. His middle career was in web development, at a small business that he still co-owns in Madison. His third career started when Kathy Barton hired him to analyze a bunch of RNA-seq data in January, 2013.

At Carnegie, Sam works on modeling transcription factor regulatory networks in the Barton Lab, and does various bioinformatics tasks in the Evans Lab and anyone else that would like some help. He is 50% at Carnegie DPB and 50% at NCGR in Santa Fe, where he lives. At NCGR, he works on data warehouse software and is delving into the genomic signatures of human diseases.
