Current Members

Shuhei Ono


My job is to help people in the lab be creative and productive.

Bill Olszewski

Lab Support

Dr. Bill helps with the operation of the lab. He automated the SF6 GC-IRMS line by using approximately two dozen pneumatic valves and pneumatically operated cold traps that are interfaced by the LabView software. Bill's creativity helps quite a bit in the daily operation of our lab.

Patrick Beaudry

PhD student (EAPS), Class of 2021

Patrick is working on melt, sulfur, and oxygen budget.

Ellen Lalk

PhD student (MIT-WHOI Joint Program), Class of 2022

Ellen is investigating microbial and thermogenic methane in the deep subseafloor.

Vanessa Sun

PhD student EAPS, from Fall 2022

Vanessa is interested in carbon sequestration and is exploring her passion in isotopes.

Gareth Izon

Postdoctoral Associate, 2016 - Present

Gareth will tell when exactly oxygen appeared in the Earth's atmosphere by analyzign S-MIF signals from drill core materials from South Africa.

Benjamin Uveges

Postdoctoral Associate

Ben is working on Archean S-MIF and early Proterozoic oxygenation event


Jeemin Rhim

PhD student (EAPS), Class of 2020

Jeemin is investigating the isotope effect associated with microbial methanogenesis.

Jeehyun Yang

PhD student (EAPS), Class of 2021

Jeehyun is working on experiments to test the origin of Archean S-MIF.

Yenny Gonzalez Ramos

Postdoc, 2015 - Present

Mihkel Pajusalu

Postdoctoral Associate, 2015 - Present

Mihkel is interested in in situ resource utilization using bacteria and microbial processes in various oxygen concentrations spanning from sub-microbar to atmospheric partial pressures. He also designed the most precise open-source trace oxygen sensor known and is working on bridging modern production methods and space technology with microbiology to pave the way for mankind's expansion to rest of the Solar system and beyond.

Kilian Ashley

PhD student (Toronto), Class of 2022

Kilian is investigating the isotope effects of low oxygen conditions on methanotrophy.

David Wang

PhD Student (MIT-WHOI), Chemical Oceanography, Class of 2017

David worked on sulfur isotope systematics of sulfate reducing microbes and then clumped methane for all sorts of methane.

Andrew Whitehill

2009 - 2015 (PhD then a short postdoc).

Currently at EPA

Danielle Gruen

PhD Student (MIT-WHOI), Chemical Oceanography, Class of 2018

Danielle is working on understanding the clumped methane isotope systematics of biogenic methane, mostly lab cultures. She moved on to do some genomics with Greg Fournier.

Eoghan Reeves


Genming Luo

Postdoc 2014 - 2016

Currently at School of Earth Science, China University of Geosciences, Wuhan.

Eliza Harris

Post Doc, 2012 - 2013

Currently at EMPA-ETH. Eliza joined the lab Sep 2012 to work on MIT-Aerodyne project for N2O isotopomer measurements using QC laser spectroscopy.

Harry Oduro

Post Doc, 2011 - 2013

Curently at Soudi Aramco. Harry joined the lab in July 2011. He conducted work on sulfur isotopes of organo-sulfur compounds.

Min Sub Sim

PhD Student, 2007 - 2012

Currently Assistant Professor at Seoul National University. Min Sub was the first PhD student who graduated from the Geobiology Program at MIT. He studied the physiological controls of multiple-sulfur isotope fractionation.

Jon Grabenstatter

PhD Student

Jon joined the MIT Geobiology Program in fall 2009. He worked to culture sulfate reducing bacteria in a chemostat culture.

Kat Thomas

Kat Thomas, Master's Student

Kat was a 5th year master's degree student who worked on the carbonate associated sulfate of Neoproterozoic and Archean rocks.

Kat Potter

PhD Student

Kat was a post-generals student in the PAOC program with Ron Prinn. She defended her thesis in July 2011. Kat worked to use isotopomer ratios of atmospheric N2O to constrain its sources, sinks and fate. She analyzed samples from Mace Head, Ireland.

Katie Donovan

Undergraduate Student

Katie was an undergraduate student at Wellesley College working to culture sulfate reducers.

Christopher Hoff

Summer Intern

Chris was a summer intern from Acton Boxborough high school, making detrital pyrite in the lab to test a hypothesis about early oxygen and sulfide weathering.

Nicole Keller

Research Fellow

Nicole was a fellow from the Swiss National Science Foundation working at our lab and with Alison Shaw at WHOI. One of Nicole’s main goals was to determine how much sulfur cycles through a subduction factory. She analyzed volcanic glasses and melt inclusions by using SF6 techniques and an ion probe at WHOI.

Sebestian Kopf

Master's Student

Sebastian was a pre-generals student with us and Dianne Newman. He tested if liquid phase reactions can produce sulfur mass-independent isotope effects.

Ying Lin

Ying helped in starting up the lab. She did some photochemical experiments on carbonyl sulfide and studied its multiple-sulfur isotope effects.

Evelyn Cordner

Undergraduate Student

Evelyn was a UROP student during the summer 2009. She worked on UV photolysis experiments of carbonyl sulfide and sulfur dioxide.

Bradley Guy

Brad was a PhD student at U of Johannesburg who worked on on multiple-sulfur isotope ratios of rocks from the Witwatersrand Supergroup to test a hypothesis around the early evolution of atmospheric chemistry.
