People

Shuhei Ono, PI
My job is to help people in the lab be creative and productive.
You can view my CV here.

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.

 

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.

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. 

 

Jeemin Rhim, PhD Student (EAPS), Class of 2020
Jeemin is working on culturing methanogens as well as methane in Icelandic steam vents. 

Patrick Beaudry, PhD Student (EAPS), Class of 2021
Patrick is working on melt, sulfur and oxygen budget.

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
Yenny is developing a new spectrometer that can meaure CH2D2. 

Kristin Woycheese, NAI Postdoc, 2015 - Present
Kristin is working on methane from serpentinization sites, and she will tell how methane finds its way there.

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.

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 to 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, 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.
