Our work concerns soil microbes and their interactions with the environment. Microbes are extremely diverse and are involved in all of earth’s biogeochemical cycles. Specifically, I am interested in understanding how climate change affects soil microbial communities, and then applying results towards modeling and predicting microbial feedbacks to climate and improving biofuels.
Congratulations to Grace Pold on achieving a Sigma Xi Grants-in-Aid award, for her project entitled "Quantifying the effect of experimental soil warming on numerically rare but ecologically dominant pathways of the nitrogen cycle."
Are you an undergraduate interested in gaining more lab research experience? Are you interested in the microbial ecology of climate change or biofuels? We may be looking for you! Our lab has room for an undergraduate researcher to perform experiments in molecular microbial ecology and microbial physiology. This student may gain experience in sterile technique, PCR, gel electrophoresis, Sanger sequencing, BLAST analysis and other bioinformatics, phylogenetic tree construction, quantitative PCR, RNA technique, and statistical analysis.
Are you interested in finding out more about what we do in the lab? I recently had the pleasure of presenting a talk for the new online Microbiology Seminar. There are new talks every month, and the old ones are archived. You can catch the archived ones at the website, and check out mine on youtube. Contact me if you have any questions, or want to help with the work!
With the start of fall semester, the lab is as big as it's ever been and we are happy to welcome our new members, and celebrate new accomplishments!
We are so excited to have Gina Chaput as our newest Microbiology graduate student in the lab! Gina has her B.S. in Genetics from the University of New Hampshire, where she studied with Dr Estelle Hrabak. Here she wrote an honors thesis studying how the accD gene in Chlorella variabilis produces the enzyme that influences lipid content for biodiesel production. She was also an undergraduate researcher in Dr. Ihab Farag’s Lab, studying Pyrolysis oil (Bio-oil) enhancement as well as Chlorella microalgae growth conditions in municipal waste water.
Soil sustains life in many ways, but soil is also a limiting and non-renewable natural resource. Current best practices, including “organic” and “sustainable” agriculture, have become both movements as well as trademarks. At best these practices and associated regulations aim to protect this valuable resource. At worst, these practices are expensive and may be harmful to the sustainability of soil and ecosystems.
In January of 2014, we were notified of the acceptance of our proposal for funding, entitled "Changes in Soil Carbon Dynamics in Response to Long-Term Soil Warming - Integration Across Scales from Cells to Ecosystems". This award is for three years of study, and the PIs are Dr. Kristen DeAngelis, Dr. Jeffrey Blanchard (UMass Biology) and Dr. Jerry Melillo (The Ecosystems Center, MBL).
Thanks to BuildAModule.com, George Drake and Steven Brewer, the DeAngelis lab has a new website! We hope you like it. Please, have a look around and if you have any questions, please feel free to contact Kristen DeAngelis, this site's administrator, by emailing kristend at umass dot edu. Thanks for visiting!
