URGE- Unlearning Racism In Geoscience

Hi y'all,

I wanted to draw your attention to a new initiative: URGE- Unlearning Racism In Geoscience ( This NSF Funded program seeks to help geoscientists learn how to create more equitable spaces through coordinated local groups (called "Pods"). 

Here's a brief overview of the mission, more detail at
"Many geoscience programs and societies are currently having conversations surrounding racism. These conversations are inspired by recent reminders (e.g., the murders of George Floyd, Breonna Taylor, and Ahmaud Arbery) that the injustices in society are reflected and perpetuated in Geoscience. Morris et al., (2020) appropriately describe the effects of racism on the careers of black, brown, and indigenous Geoscientists by stating that “in place of mass incarceration, there is mass exclusion [and] in place of police brutality, [geoscience] careers are killed through forced attrition and under-investment.” Like the rest of the world and academia, the Geosciences need to unlearn racism.

We designed a community-wide journal-reading and policy-design curriculum to help Geoscientists unlearn racism and improve accessibility, justice, equity, and inclusion (AJEDI) in our discipline. We call this program Unlearning Racism in Geoscience (URGE; URGE’s primary objectives are to (1) deepen the community’s knowledge of the effects of racism on the participation and retention of black, brown, and indigenous people in Geoscience, (2) use the existing literature, expert opinion, and personal experiences to develop anti-racist policies and strategies, and (3) share, discuss, and modify anti-racist policies and strategies within a dynamic community network and on a national stage. By meeting these objectives, we hope that Geoscience departments and societies will be able to implement a well-researched crowdsourced group of anti-racist policies."

 Congratulations to the excellent PIs and coordinating crew!

PhD opportunities – Organic Geochemistry Group at CU Boulder

The Organic Geochemistry Group in the Department of Geological Sciences and the Institute of Arctic and Alpine Research (INSTAAR) at the University of Colorado Boulder is seeking for prospective students interested in pursuing a PhD in Geosciences in the fields of (1) paleoceanography and (2) ocean biogeochemistry.

1. Evaluating Climate Change and Kill Mechanisms Associated with the End-Cretaceous Mass Extinction: A Model-Data Comparison Approach. This PhD project aims to tests hypotheses about the relationship between dramatic climate change, marine ecology, and carbon cycling across the Cretaceous/Paleogene mass extinction event. Research includes laboratory and analytical activities examining lipid biomarkers and their stable isotope composition using samples from ocean and continental drilling, which will be incorporated into climate and biogeochemical models.  

2. Microbial Lipidomics in Changing Oceans. This PhD project aims to tests hypotheses about lipid remodeling in marine microbes as a physiological adaptation to multiple environmental stressors using observational (cruises) and experimental (microcosm and mesocosm experiments) approaches. Research includes laboratory and analytical activities examining intact polar lipids (IPLs) and their degradation products (core lipids), which will be incorporated into larger dataset of metagenomics, metatranscriptomic, and geochemistry.

Applications from students with a robust foundation in Earth sciences, or related disciplines, and from diverse backgrounds and traditionally marginalized groups in STEM fields, are particularly encouraged to apply. Familiarity with organic and/or stable isotope geochemistry, paleoenvironmental sciences, oceanography, and data analysis is desired, but not essential. Interested candidates should contact Dr. Julio Sepúlveda (, including a brief interest statement and a CV/resume as a single PDF file.

The Organic Geochemistry Group is a diverse group of researchers from different backgrounds and nationalities that welcomes and embraces diversity. We are part of the Organic Geochemistry Lab, a state of-the-art analytical facility equipped with instrumentation in gas and liquid chromatography, low- and high-resolution mass spectrometry, and stable isotope ratio mass spectrometry, with an active network of collaborators. As the flagship university of the state of Colorado, CU Boulder is a dynamic community of scholars and learners with a proud tradition of academic excellence situated on one of the most spectacular college campuses in the country. Collectively, CU Boulder researchers produce more papers in the geosciences—and generate more citations to those papers—than those at any other university in the world.
