Background

I grew up in Northern California, attended Brown University as an undergraduate and did my Ph.D. research in the Department of Biological Sciences at Stanford University. My thesis advisor was Hal Mooney. The core of my dissertation research was published in Oecologia (Dukes 2001) and Ecological Applications (Dukes 2002).

After grad school, I spent two years as a Hollaender Postdoctoral Fellow in the lab of Jim Ehleringer at the University of Utah. I worked on several projects during this time. Early results from one of these projects were published in Ecology Letters (Hooper & Dukes 2004). The project from this time period that garnered the most attention was my paper "Burning buried sunshine," published in Climatic Change (Dukes 2003).

During 2002 and 2003, I helped coordinate the Jasper Ridge Global Change Experiment. This project, led by Chris Field and currently in its ninth year, applied warming, elevated CO2, nitrogen, and water (in a full factorial design) to plots of California grassland. A fire that burned through part of the experiment in 2003 changed the experimental design somewhat, and added interesting new angles. I and other researchers on this project are investigating how ecosystems will respond to predicted future climate and atmospheric conditions. We're studying the productivity of ecosystems, interactions among various members of plant communities, carbon storage on land, and other properties of ecosystems. Currently, I am collaborating on a data-model intercomparison, and also examining how the various aspects of global change influence the success of yellow starthistle, the invasive species used in some of my previous work.

For several years now, David Hooper (Western Washington University) and I have been studying how the functional group composition and richness of a plant community affect that community's invasibility. We are attempting to correlate resource availability with invasibility, and we are examining whether functional group diversity moderates the impact of invaders. Dave has a more detailed description of the project on one of his web pages. I have some photos of the research site here. In a separate study, I am examining how plant leaf d13C varies along gradients of precipitation, and with plant functional type.

I am working with Lindsey Rustad (USFS) and several other researchers on NE Forests 2100. This project will compile and publish a synthesis of climatic change research in the northeastern U.S. and eastern Canada.

With funding from the National Science Foundation and the Department of Energy (National Institute for Climatic Change Research), my group is currently directing the Boston-Area Climate Experiment (BACE) in Waltham, Massachusetts. The BACE is designed to characterize old-field responses to climate change, and features 4 levels of warming across each of three precipitation treatments. I welcome inquiries from researchers, prospective students, and middle- and high-school teachers who are interested in getting involved with the BACE.



Some of the questions being asked in my lab


For interested students:

Interested in ecological research? Interested in how people are affecting ecosystems? If so, consider joining the lab.

Are you an undergraduate looking for experience, or interested in doing honors research?

I sometimes have openings for motivated undergraduates to conduct research in the lab. I can almost always accommodate students interested in conducting honors research. These students should contact me as early as possible so that we can develop a suitable project. I also sometimes can take on students looking to help with research on a volunteer basis or for credit, or to take on an independent project. If you are interested in working in the lab, please contact me and indicate your range of interests, relevant courses you have taken (or experience), and, if possible, provide me with the names and contact information for references, along with their relationship to you.

Are you considering graduate school?

I am interested in taking on additional graduate students. If you are looking for experience in the field of ecology and you think any of my research topics are interesting, please send me an email with information about yourself. If possible, include information on your interests, classes taken, grades, and GRE scores. I expect students in the lab to work hard, learn a lot, and have a great time. My interests are broad, so projects on a wide variety of topics are possible. There are a variety of avenues through which prospective graduate students can apply to the lab at Purdue, such as through the Department of Forestry and Natural Resources, the Department of Biological Sciences, and the Ecological Sciences and Engineering (ESE) Program. I am also looking to accept a new student into my lab at UMass Boston through a newly funded collaborative project (see below). For most students, it would be wisest to discuss the range of options with me before applying. If you are an international student and you did not graduate from an English-speaking institution, you should apply to work with me only through the Department of Forestry and Natural resources, unless your score on the TOEFL speaking test is 27 or higher. Purdue has excellent resources for ecological research, including instrument facilities of all kinds on campus, properties and well-equipped field stations throughout Indiana, and good support for students. The Lafayette/West Lafayette area has a low cost of living and a high quality of life. It is also within about an hour's drive of Indianapolis and two hours of Chicago. There is a rich community of ecologists at Purdue, spread across several departments, conducting research around the world. In Forestry and Natural Resources, the ecologists are listed together here. In Biological Sciences, they can be found here. More can be found in Agronomy, Entomology, Earth and Atmospheric Sciences, and other departments. Purdue also has a terrific group of researchers working on many aspects of climate change.

An exciting new project at UMass Boston: Do plant roots culture microbial communities that facilitate or inhibit growth of their competitors? We want to know. In collaboration with Rick Kesseli, Adan Colon-Carmona, and Mike Shiaris, my lab is researching how interactions between soil microbes and plant roots affect intraspecific competition among plants, and which plant genes regulate these effects. We have new funding for this project, and I am looking to accept a graduate student into my lab at UMass Boston to tackle some of the fascinating ecological angles of this question. The student will join a team of plant and microbial ecologists, plant geneticists, and plant molecular biologists to tackle ecological questions in the rapidly growing field of plant-microbe interactions. Please contact me if you are interested (see instructions above)!
