2021 Division Awards for outstanding geobiologists

Every year the GBGM executive committee selects exceptional scholars to receive awards for their accomplishments in research, education/mentoring, and service in geobiology. This year we had an exceptional list of nominees so thanks to all those who nominated someone!

We are pleased to announce that the 2021 awards go to Kim Lau (pre-tenure), Phoebe Cohen (post-tenure), and Frank Corsetti (distinguished career). Please check out their brief biographies below and explore their websites for further details about their research.

Pre-Tenure Award Recipient: Kimberly Lau (Pennsylvania State University)

Dr. Kim Lau is an Assistant Professor in the Department of Geosciences at the Pennsylvania State University. Her research focuses on reconstructing biogeochemical changes in Earth’s past and specifically the causes and consequences of redox changes in ancient oceans using a combination of lab, modeling, and field methods. She is interested in major perturbations throughout Earth history and how these events are recorded geochemically in the sedimentary record. Her approach includes better understanding the sedimentary geochemical and isotopic proxies that geobiologists can employ to constrain past environmental change.

Post-Tenure Award Recipient: Phoebe Cohen (Williams College)

Dr. Phoebe Cohen is an Associate Professor in Geosciences at Williams College. Phoebe is a paleontologist who uses a wide array of microscopic, microchemical, and geochemical techniques, in combination with field-based stratigraphy and sedimentology, to reconstruct ancient organisms and ecosystems. Her current work focuses on the evolution of eukaryotes in the Proterozoic and the microfossil record of the end-Devonian mass extinction. She is also actively involved in justice, equity, diversity, and inclusion work in the geosciences. 

Distinguished Career Award Recipient: Frank A. Corsetti (University of Southern California)

Dr. Frank Corsetti is a Professor of Earth Sciences at the University of Southern California.  He studies the co-evolution of the Earth and its biosphere from a geobiologic/sedimentologic perspective, searching for traces of life in deep (and not so deep) time.  Key topics of study include the identification of biosignatures (in particular, those left behind by microbes), unraveling the diagenetic alteration of biosignatures, mass extinctions, the environmental setting for the emergence of animals, and the search for life beyond Earth.  Frank co-directed the International Geobiology Summer Course from 2010-2016.  He is a fellow of the Geological Society of America, recipient of the SEPM Dickinson Medal, the 2019 James B. Thompson Distinguished International Lecturer, and a recipient of the Mellon Mentorship award for mentoring graduate students.

Please join us in congratulating these exceptional scientists at the 2021 GSA (hopefully) in Portland; the awardees will be giving invited talks in our "New Voices in Geobiology" and "New Advances in Geobiology" sessions! The Geobiology Division Award Presentation (a.k.a. the GBGM Lunch) will be held virtually since this year's meeting will be offered in a hybrid format with limited in-person attendance.

Geobiology sessions at GSA 2021 in Portland, Oregon

 Hi GBGM members, 

We are excited to be hosting two sessions and to be hosting so many exciting sessions covering a wide range of topics in geobiology at GSA 2021 in Portland (October 10-13, 2021) this year! 

Our two sessions, T124. New Advances in Geobiology and T125. New Voices in Geobiology will both highlight new hypotheses, methods, and field sites that address questions at the intersection of geological and biological processes. T125. New Voices in Geobiology will specifically aim to highlight early career researchers in our field. We are aiming to host these as hybrid sessions so that we can accommodate both in-person and remote presenters for oral presentations! 

We are also sponsoring 22 other excellent sessions that will cover a wide range of geobiology topics, from the Precambrian to the modern, and from Earth to Mars!

We hope that you'll submit an abstract to any of these sessions, and we'll see you (in person or virtually!) in Portland in October!

Nominate your colleagues for a GSA GBGM Award!

Dear Geo(micro)biologists,


Every year the GSA Geobiology and Geomicrobiology division selects three exceptional researchers to receive pre-tenure, post-tenure, and distinguished career awards (or equivalent career stage in a non-tenure track position). For details on past awards, see the GBGM website. Since 2018, the division leadership has solicited nominations from our members in order to create a more diverse and inclusive nominee pool, both in terms of academic fields and demographics. We also hope this process allows our members to feel more involved and empowered to nominate the people who have made a difference to them or their (sub)field.


Please use this nomination form to identify exceptional researchers who you think should be recognized, along with justification (max. 500 words). Final nominees will be selected by the GBGM division representation committee from amongst this pool, and awarded based the nominee’s complete portfolio (i.e., research, mentoring, teaching, service, and leadership). Please note that this year you must confirm that the person you are nominating has not breached GSA's Code of Ethics & Professional Conduct nor is under investigation for any action that would be a breach of GSA's Code of Ethics & Professional Conduct.


We're grateful for your participation in this process - we know that your time is valuable, but this is one of the most important things the division does, and we think the community should nominate our awardees. Please submit your nominations to the division chair, Vicky Petryshyn ( by Sunday, March 21st.


We look forward to being overwhelmed with nominations!


Vicky, Trinity, David, Emmy, Rowan, Lydia, Brandt, Andrew, Alison, and Zoe (a.k.a. your Geobiology and Geomicrobiology Division Representatives)

Historical Ecology Postdoctoral Fellowship

Historical Ecology Postdoctoral Fellowship at William & Mary 

The Environmental Science and Policy (ENSP) program at William & Mary seeks applications for a two-year postdoctoral scholar position in the historical ecology of the precolonial Chesapeake. Supported by W&M faculty, the postdoctoral fellow will develop a historical ecological study of shell midden deposits linked to questions of sustainability, traditional ecological knowledge, and biological conservation in the Chesapeake. 

The postdoctoral fellow will develop a research and teaching program bridging the social and natural sciences through a study of a Native American community and its relationship with the Chesapeake oyster fishery over the long term. This position offers the successful candidate an opportunity to use her/his skills to lead cutting-edge research and facilitate undergraduate projects while receiving mentorship in professional academic development. The postdoctoral scholar will also teach one upper-level seminar course per academic year, a summer session course, and arrange an environmental speaker series in the second year. 

The position offers a competitive salary, research and travel funds, and administrative support. The postdoctoral fellow will be mentored by two William & Mary faculty (Rowan Lockwood, Martin Gallivan) with teaching and research interests in Chesapeake archaeology and marine paleobiology. 

For full consideration please submit CV, cover letter, and a diversity statement detailing how the applicant will contribute to diversity in the program and W&M more broadly by the review date, 3/24/21. Additional information and application link may be found online:

Required Qualifications: A PhD in Anthropology (Archaeology specialty preferred) or a closely related discipline (e.g., Paleontology, Historical Ecology, Geography) is required by the time of appointment, August 10, 2021. Since the COVID-19 pandemic has negatively affected the progress of many doctoral students, applicants who have scheduled a dissertation defense prior to apportionment date will be considered for the position. 

Preferred Qualifications : Teaching expertise/interests at the intersection of the social and natural sciences is preferred, but not necessary. 

William & Mary values diversity and invites applications from underrepresented groups who will enrich the research, teaching and service missions of the university.
