Recruiting for competitive PhD fellowship (Fall 2025) in soil C biogeochemistry

I am currently seeking applicants for a competitive Ph.D. fellowship in the Department of Earth & Environmental Science. A range of potential projects are possible, centering on soil carbon biogeochemistry, including quantification and characterization of the persistent pools of pyrogenic and geogenic carbon in dark/black soils, examination of potential upper limits to soil carbon stabilization, and the energetics of soil organic matter cycling and persistence. Positions are ideal for candidates who have completed an MSc in soil science, geosciences, environmental chemistry, ecosystem science or related fields, but outstanding BSc graduates in such programs will be considered. Applications can be submitted directly online (https://www.applyweb.com/upenng/).

Sustainability and Conservation Science Postdoctoral Fellowship at the University of Pennsylvania in partnership with The Nature Conservancy

Application Deadline: Friday, February 16, 2024

This postdoctoral fellowship program aims to bridge the excellence in academic research at the University of Pennsylvania (Penn) and in conservation practice at The Nature Conservancy (TNC) to confront climate change, while creating a new generation of sustainability and conservation leaders who combine the rigor of academic science with real-world application.

Penn and TNC join in recognizing climate change as the single greatest environmental threat to humanity. Climate change is an issue that tightly integrates the health of the planet with the economy, access to clean and reliable energy, water, and food production, and equity. To tackle these challenges, our world needs science that blends climatology, physics, economics, business, chemistry, engineering, technology and communications with conservation and ecology. As well, it must marry the best academic research with opportunities for rapid testing and deployment in the real world to address human well-being.

The specific program goals are to:

  • Invest in the talent potential of a new generation of climate change leaders
  • Recruit scientists who bring a diversity of culture, experience, and ideas to Penn and TNC
  • Support innovative and impact-oriented research that helps deliver TNC outcomes
  • Provide the fellows and Penn research community as a whole with access to real-world conservation professionals and issues.

Postdoctoral Fellows will be supported annually with a $65,000 stipend and benefits, a $10,000 research fund, and up-to $2,000 for professional travel. A one-time relocation reimbursement of up-to $2,000 is also available. Fellows will be eligible for support for up-to two consecutive years.

I am recruiting a postdoc to work with Stephen Wood at TNC and myself on agricultural carbon sequestration. If interested, send me an email.

Solihat NN, T Acter, D Kim, AF Plante and S Kim. (2019) Analyzing solid-phase natural organic matter using laser desorption ionization ultrahigh resolution mass spectrometry. Analytical Chemistry. 91:951-957. doi:10.1021/acs.analchem.8b04032. Collaborators at Kyungpook National University in Daegu, South Korea have been working on laser desorption methods for solid phase high resolution mass spectrometry analysis of natural organic matter. The study represents our first tests of the method using powdered IHSS humic and fulvic acids as well as soil. We demonstrate a proof-of-principle that highly sensitive, direct, molecular level analysis of solid-phase NOM from unprocessed soil samples and minimum sample preparation is possible.

 

PhD fellowships available for Fall 2019 in soil C biogeochemistry

The Terrestrial Biogeochemistry Laboratory in the Department of Earth and Environmental Science of the University of Pennsylvania invites applicants for competitive Ph.D. fellowships in soil carbon biogeochemistry. Projects seek to quantify and characterize the recalcitrant pools of pyrogenic and geogenic carbon in soils. We’ll examine chemical transformations and dissolution as mechanisms controlling their fate in the critical zone. Positions are ideal for candidates who have completed an MSc in soil science, geosciences, environmental chemistry, ecosystem science or related fields, but outstanding BSc graduates in such programs will be considered. For further information, please contact Dr. Alain Plante by email (aplante@sas.upenn.edu) or consult the department website (www.sas.upenn.edu/earth). Applications can be submitted directly online (https://www.applyweb.com/upenng/) before December 15.

Happy to announce the publication of:

Williams EK, ML Fogel, AA Berhe and AF Plante. (2018) Distinct bioenergetic signatures in particulate versus mineral-associated soil organic matter. Geoderma. 330:107-116. doi:10.1016/j.geoderma.2018.05.024. This paper was part of Elizabeth Williams’s research program while at the University of Calfornia, Merced, which we expanded on using thermal analysis of the density fractionation samples. We found that light-fraction particulate SOM and heavy-fraction mineral-associated SOM had distinct thermal analysis, and thus bioenergetic, and chemical signatures. These signatures provided further insight into their composition and mechanisms of stabilization in soils from a climosequence from the Sierra Nevada Mountains in California.
