(2000) Associate Professor of Biological Sciences; University of Oregon, B.S., 1987; St. John's College, M.A., 1989; Massachusetts Institute of Technology, Ph.D., 1997
Runs the lab sections of 201K: Interdisciplinary Inquiry in the Sciences of the Human Body
I am currently funded through NSF Biological Oceanography (NSF-OCE 0851288) to examine the ecophysiological diversity and characterization of different clades within the low light adaptedProchlorococcus ecotype.
One of my recent projects involves studying nitrate utilizing Prochlorococcus that have been isolated in the last 5 years. This project is in collaboration with Drs. Penny Chisholm, Paul Berube and Steve Biller at Massachusetts Institute of Technology, Dr. Adam Martiny at University of California, Irvine, and Dr. Lisa Campbell at Texas A&M University. My lab has helped with generating axenic (free of heterotrophic bacteria) Prochlorococcus cultures and analyzing the nitrate utilization physiology of these new axenic strains. The genomes for many of these strains have been sequenced at MIT and we are in the process of annotating the genomes.
Next Generation Phenomics for the Tree of Life
I am co-PI on one of three projects recently funded by NSF AVAToL (Assembling, Visualizing and Analyzing a Tree of All Life) program. Phenomics refers to the morphological, physiological and ecological characteristics of organisms. I will be helping coordinate the project for microbial organisms and develop educational and crowd-sourcing modules so students and the public can participate in generating and/or pulling together phenomic data that can then be used by scientists to help with analyzing, annotating and visualizing the Tree of Life. The project is in collaboration with lead-Principle Investigator, Maureen O'Leary at Stony Brook University (http://www.anat.stonybrook.edu/people/facultypage/oleary), 6 other co-PIs from 5 different universities, and a consortium of 12 additional researchers from around the US who will work together to pull together the tools for high-throughput phenomic data collection.
