Brad E. Rosenheim, Ph.D.

    -Principal Investigator

Dr. Rosenheim is an isotope geochemist interested in establishing records of Earth’s climate variability and generating information about the carbon cycle that is intricately tied to climate.  He directs SILT U and mentors students interested in learning isotopic and geochemical techniques useful in their studies.  He has enjoyed the recent success of the Philadelphia Phillies, but fears the short era is over.




Department of Earth and Environmental Sciences                                  Tulane University

Elizabeth Williams

    -Ph.D. Student

Elizabeth began her studies at Tulane in fall of 2009 after graduating from Howard University with a B.S. in Chemistry.  She hales from the New Orleans region and is interested in applying carbon cycling studies to the region’s problem of disappearing wetlands.  Elizabeth has a profound attachment to the carbon atom.

Alvaro Fernandez

    -Ph.D. Student

Alvaro joined SILT U in the fall semester of 2010, and has already presented his research at AGU.  His current project focuses on using improved dating and precise radiocarbon measurements in corals and sclerosponges to discern changes in the flow of the tropical N. Atlantic over the last several hundred years.  It will take him much less time to finish his degree at this rate, though.

Matt Pendergraft

    -M.S. Student

Matt comes to Tulane from San Diego via Argentina with an interest in studying the BP Oil Spill in the Gulf of Mexico.  Eventually, he is looking to earn a Ph.D., but for now he wants to see how he can contribute to the effort to understand oil pollution in the Gulf.  His introduction to Gulf Coast beaches was digging for oil on Grand Isle.

Jianwu Tang, Ph.D.

    -Laboratory Manager

Jianwu came to SILT U in September of 2010 to manage the laboratory.  He has done postdoctoral investigations in Austria and here at Tulane, and is interested in multiply substituted isotopologues of carbon dioxide and applications of ramped pyrolysis radiocarbon dating.

Joanna Kolasinski

    -Postdoctoral Fellow

Joining us from La Reunion, France, Joanna is a marine scientist with a wealth of experience in isotope geochemistry.  Her post is supported by the CARTHE consortium, and she will be studying isotope indicators of oil in benthic marine sediments.  Coming from France, she will have to learn to pronounce the French names of New Orleans streets and neighborhoods in New Orleanian.
