We study plant response to environmental change - on seasonal to million-year timescales - using modern and fossil substrates.
(past 12 months)
- We had TWO Grand Prize winners at the 18th Graduate Student Symposium at the University of Louisiana at Lafayette! Jamie Vornlocher won for her poster titled, "An assessment of monsoon variability under elevated atmospheric carbon dioxide levels," and Robert Narmour won for his talk titled, "Extreme precipitation events recorded in the oxygen isotope composition of tree-ring cellulose." Congratulations to both students!
- Our work to determine the source and magnitude of atmospheric CO2 change across Paleogene global warming events was published as an invited research article in Global and Planetary Change. See the Publications page for more information.
- Bill Lukens presented his research (with co-author Peace Eze, B.S. Geology 2018) at the 2018 Goldschmidt conference in Boston, MA. This and our other lab abstracts can be found here.
- New paper, "Plant growth chamber design for subambient pCO2 and δ13C studies" has been published in Rapid Communications in Mass Spectrometry. See Publications page for more.
- We welcome Dr. Bill Lukens to the lab! Bill received his Ph.D. in Geology from Baylor University.
- Jamie Vornlocher presented her thesis research at the Graduate Student Research and Project Showcase.
- Our new review paper on interpreting carbon isotope records has been published in Earth-Science Reviews (open access!). A link to the paper can be found on the Publications page.
- Congratulations to Collin Moore (M.S.), Rose Telus (M.S.), and Peace Eze (B.S.) on their graduations!
- We presented our recent work at the AGU Fall Meeting in New Orleans, LA. Links to our abstracts can be found here.
- Peace Eze presented her research at the Annual Honors Undergraduate Research Conference (abstract) (photo).
- Peace Eze has been awarded the Fall 2017 Outstanding Graduate from the Ray P. Authement College of Sciences! Congratulations, Peace!
- Brian presented the lab's work at the Jackson School of Geosciences at UT Austin as part of the DeFord Lecture Series and Paleontology Seminar.
- Rose Telus successfully defended her thesis work, "Identification of heavy rainfall events using high-resolution carbon isotope measurements across tree rings."
- A press release of our recent paper on early Paleogene CO2 levels is available here.
- Brian will be presenting two talks at the AGU Fall Meeting in New Orleans, LA. These and our other lab abstracts can be found here.
- Our latest work (with postdoc Ying Cui, now at Dartmouth College) to reconstruct atmospheric CO2 levels across past global warming events was published in Earth and Planetary Science Letters.
- Rose Telus' abstract was accepted for an oral presentation at the GSA meeting in Seattle! Her abstract can be found on the lab Abstracts page.
- Congratulations to Taylor, Steve, Umatu, and Leslie for all graduating with their M.S. degrees this summer!
- Collin Moore successfully defended his thesis on fossil wood from far northeastern Siberia.
- Could Jurassic Park actually happen? Research on microbes trapped in salt may provide clues (article here).
