Farewell, Maya!

It is with a sad heart that we say goodbye to our postdoctoral fellow Maya Gomes, who has gone on to bigger and better things as an Assistant Professor at Johns Hopkins. We wish her all the luck in her new position! [And hope she comes back to visit often!]


Geobiology 2017

The Geobiology Society kicked off its inaugural meeting June 11-14, 2017 in Banff!  A great gathering of geobiologists from around the world. 





Looking forward to Geobiology 2019: The Return to Banff

Welcome, Morgan

We recently welcomed a new postdoctoral fellow to the lab. Morgan Raven comes to us from the California Institute of Technology, where she recently defended her PhD thesis under Alex Sessions. We look forward to seeing Morgan’s next projects in the Fike lab!

In other news, the biogeochemistry group had a great weekend in Cincinnati for the fifth annual Midwest Geobiology conference. Many thanks to the folks at the University of Cincinnati for organizing the event.

Hello, Goodbye

Our lab group said goodbye last Friday to our postdoctoral fellow Cole Edwards, who has gone on to bigger and better things as an assistant professor of carbonate sedimentology and stratigraphy at Appalachian State Univeristy in North Carolina. He first joined our group in August 2014 and researched Paleozoic environmental and biogeochemical changes. We wish Cole all the luck in his new position!

Joining us as a postdoctoral fellow from Harvard University is Maya Gomes. Maya focuses on how the cycling of elements through the ocean and atmosphere regulates climate and habitability. We welcome Maya and are eager to see what she will accomplish.

A change of hands

After eight years at Wash U, we wish Dwight ‘Mac’ McCay all the best as he moves on to a position as project scientist with TRC Solutions. Mac started working at Wash U in April 2008 with Bob Criss’ lab, and became manager of the Fike lab when it began in January 2009.
The illustrious job of lab manager is now being passed to former tech Stephanie Moore. We also wish her the best of luck in her new position!

Congratulations, Roger!

Congrats to Roger Bryant for defending his research paper, “Depositional controls on the S-isotopic composition of framboidal pyrite in marine sediments” on March 24, 2016. Both of our grad students can hopefully now breathe easy with their orals behind them.

Congratulations, Jocelyn!

Congratulations to Jocelyn Richardson for passing her orals on March 4, 2016. She successfully defended her research paper, “Correlating the Spatial Distribution and Speciation of Sulfur associated with Sedimentary Carbonate Strata, with its Isotopic Composition using Coupled X-ray Spectromicroscopy and Secondary Ion Mass Spectrometry.

Welcome Cole Edwards

Cole is the new postdoc joining the lab, fresh off finishing his Ph.D. at Ohio State. Cole is interested in better constraining environmental and biogeochemical evolution over the Paleozoic.


Welcome Cole!

Onward to Dublin: Farewell Dr. Rose

We are sad to see Dr. Catherine Rose, the department’s inaugural Fossett Postdoctoral Scholar, depart our lab after two very productive (and enjoyable) years. Catherine will begin her new position as an Assistant Professor at Trinity College Dublin this fall.


You will be sorely missed!
