Two new faculty are being recruited for positions at the assistant professor level at the University of Tennessee Knoxville in the Ecology and Evolutionary Biology Department (EEB)!
Position 1: Field botanist and herbarium director (http://eeb.bio.utk.edu/fieldbotanysearch/)
Position 2: Ecologist – any area (http://eeb.bio.utk.edu/ecologysearch/)
We completed field work during the week of August 11th, for a new study to create a “microbiome atlas” of symbiotic associations in Populus as part of our Plant-Microbe Interfaces project at ORNL. We partnered locally this time to sample trees in Blount County, Tennessee that are part of a field trial run by the UTIA Center for Renewable Carbon and Dr. Tim Rials. Due to the large sample sizes required for our new metagenomics approaches, and the fact that we needed to dissect out many different tissues, this was a large effort and required bringing in some help and power equipment from experts at Wolf Tree Company.
While there have been numerous studies of the microbial associations of individual plant environments (e.g. the rhizosphere, phylosphere or endosphere) very few have simultaneously examined variation across habitats of the plant as a whole. Simultaneous examination should allow us to better understand microbial the niche specialization and niche overlap of symbiotic partners across the overall tree environment. This will allow us to build an “atlas” of the microbial interactors with Populus trees and better links to their potential functions across Populus. The sampling strategy employed will enable us to comprehensively survey rRNA based microbial diversity across approximately 30 different tissue level habitats in Populus. These were sampled accross different locations within individual trees, between five replicate clonal trees, and across two contrasting genotypes (P. deltoides and P. deltoides X trichocarpa hybrids). Selected plant habitats are also to be examined using metagenome DNA sequencing that will include soils, rhizospheres, root endospheres, heartwood, and leaves that are replicated from samples pooled across the individual trees. Samples are also being used for culture isolations and single cell genomics of targeted microbial species (ectomycorrhizae, Atractiella, Acenitobacter, etc.).
A few months ago, on a bit of a whim, I submitted a little piece of creative/experiential writing I did for publication in the Belle Reve Literary Journal. After over 70 science publications that involved coauthors, peer-reviewers as well as numerous rejections, re-writes and revisions, I was pleasantly surprised when two days later I got a simple email from the editor saying they wanted to publish it in their summer issue! Anyway, here is a link to the journal issue containing my first ever non-science publication!
I have a new postdoc position available by the end of August or perhaps earlier if the right person can be found! Please email directly if you have technical questions about the position. Otherwise “official” applications will be accepted only via the RECRUITING.ORNL.GOV website.
Thought I would post some photos of the first field work outing of the year. We were out on the Caney Fork River in Central Tennessee where we have done several studies in the last few years. Primary objective was to obtain cuttings of trees for some upcoming greenhouse experiments. Secondary objective was to play with the “big shot” which is the giant sling shot we used to get lines over the tall limbs to bring them down to get the cuttings. Both were a success!
In the last month we have welcomed both Cyd Hamilton and Laurel Kluber into our group at ORNL. Cyd is a Visiting Scientist and ORISE Fellow working with us on plant fungal interactions on the PMI Project. Laurel Kluber is a Postdoctoral Associate working with us on the SPRUCE project as well as our Soil Carbon Cycle Modeling collaborative projects with ESD staff scientists Melanie Mayes and Gangsheng Wang. Check out the updates on the “People” page!
Here are links to three new accepted papers that are just out online. These papers represent some of the first of our hopefully continued fruitful efforts to characterize the peatland SPRUCE site characteristics prior to the onset of warming treatments next year. These come from core support of the SPRUCE project itself as well as an additional DOE funded effort led by my long-time collaborator Joel Kostka at Georgia Tech and of course the hard work of several fabulous students and postdocs!

It has been some time since I posted on the blog and I hope this will be one of several upcoming updates on projects, papers and personnel!
Applications are now being accepted for the 2014 Summer Department of Energy (DOE) Science Undergraduate Laboratory Internship (SULI), Community College Internship (CCI) and Visiting Faculty (VF) programs!
If you are aware of students or faculty that may be interested in a summer internship (dates are June2 – August 8, 2014), please have them visit http://science.energy.gov/wdts/ to apply or obtain additional information! The application deadline is 5:00 p.m. ET on January 10 – applications received after this time WILL NOT be considered for placement. Summer appointments are 10 weeks in duration and selected applicants must be available to participate for the entire appointment period.
The SULI program encourages undergraduate students to pursue science, technology, engineering and mathematics careers by providing research experiences at DOE laboratories. The Community College Internship (CCI) program seeks to encourage community college students to enter technical careers relevant to the DOE mission by providing technical training experiences at the DOE laboratories. The Visiting Faculty (VF) program seeks to increase the research competitiveness of faculty members and their students at institutions historically underrepresented in the research community in order to expand the workforce vital to the DOE mission areas.
NOTE: If you are interested in an internship opportunity through this program in my lab directly I will probably be accepting one or two with interests in microbial ecology and/or soil biogeochemistry. Please drop me an email (schadtcw at ornl dot gov) when you complete your application so that I know to specifically look for your application amongst the 100s in the overall program which ranges from ecology to particle physics!
