Postdoctoral Fellow, Ecosystem Ecology and Global Change Science

Description

The O’Connell Research Group in the Schmid College of Science and Technology of Chapman University invites applications for a
Postdoctoral Fellow position in Ecosystem Ecology and Global Change
Science effective December 2026.

This postdoctoral position is available beginning December 2026 for one individual to join Dr. O’Connell’s research group to investigate the ecological impacts of global change, with a focus on biogeochemical cycles and ecosystem science in wet tropical forests. The position offers the opportunity to collaborate with an
NSF long-term ecological research (LTER) location (Puerto Rico’s
Luquillo LTER) and data synthesis work on biogeochemistry data from drought, warming and/or hurricane experiments carried out in the
Luquillo LTER.

Chapman University is a nationally-ranked institution offering traditional undergraduate and graduate programs in the heart of
Orange County, one of Southern California’s most diverse and vibrant regions. The University achieved R2 status in the Carnegie
Classification of Institutions of Higher Education, a distinction held by just 10 percent of all U.S. universities and is ranked #100 among Best National Universities by US News and World Report
(2027). Our faculty include academic leaders who excel in research, publishing, and world-class teaching in our 11 schools and colleges, including the Schmid College of Science and Technology.
Dedicated to forward-looking, personalized education, we create an environment for unlimited achievement by both our students and faculty. More information about Chapman University is available at www.chapman.edu.

Responsibilities

We are seeking a passionate individual eager to broaden their expertise in ecosystem ecology, global change science, and data synthesis. The postdoctoral researcher in this role will have the opportunity to:

• Support the synthesis and publication of biogeochemistry data

from drought, warming, and/or hurricane experiments conducted at the Luquillo Long-Term Ecological Research (LTER) site in Puerto
Rico.

• Apply time series and forecasting models to assess the effects

of global change on carbon and nitrogen cycling, with a focus on understanding shifts in variability and resilience.

• Conduct biogeochemical lab experiments and contribute to

building lab systems and structures in the O'Connell lab space in the Keck Center for Science and Engineering.

• Mentor undergraduate researchers, engage in professional

development activities, and participate in grant writing and teaching if desired.

The postdoctoral researcher will conduct independent research and/or collaborate with ongoing lab projects, provide guidance and support to undergraduate students associated with the related projects, and document research activities and publish key findings in high-quality, peer-reviewed journals. We are especially interested in candidates who thrive in collaborative environments and value inclusive mentorship.

Qualifications

• A PhD awarded in the last five years, with preference given to

candidates with a degree in ecology, environmental science, earth science, soil science, biogeochemistry or related field.

• Demonstrated experience in ecosystem science data analysis,

biogeochemical research, remote sensing applications, and/or time series modeling.

• Demonstrated experience in lab-based biogeochemical

techniques.

• Skills in R, Python, or other relevant programming languages

for ecological data analysis and modeling.

• (Preferred) An ability to work both collaboratively and

autonomously, mentoring students of various levels.

Application Instructions

Interested applicants should submit the following documents via
