Members of the Kroll Lab

Jesse Kroll, Associate Professor

Education: A.B., Harvard 1996, Chemistry and Earth and Planetary Sciences; Ph.D., Harvard 2003, Chemistry
Contact: jhkroll @ mit.edu; (617) 253-2409; MIT Bldg 48-331

Jesse's interests lie in the chemical transformations that organic compounds undergo in the atmosphere. His graduate work focused on gas-phase reactions, and his postdoctoral work (at Caltech) on the formation of secondary organic aerosol (SOA). He was then a Senior Scientist at Aerodyne Research, Inc., developing and using mass spectrometric tools to characterize organic aerosol. He joined the MIT faculty in 2009.

Ben Crawford, Postdoc

Education: B.S., U. Indiana 2003, Geography; Ph.D., University of British Columbia 2014, Geography
Contact: bencrawf @ mit.edu

Ben’s background is boundary layer meteorology and developing sensor networks. He is especially interested in land-atmosphere interactions in complex terrain (including biogeochemical & energy cycles, wind & turbulence, and air quality) and enjoys windy places and high views.

Abigail Koss, Postdoc

Education: A.B., MIT 2012, Chemistry; Ph.D., CU-Boulder 2017, Analytical Chemistry
Contact: arkoss @ mit.edu

Abby's thesis research comprised applications of PTR-MS to tropospheric measurement of VOCs associated with fossil fuels, with a particular focus on air quality impacts of oil and natural gas production. Her research interests include the development and application of mass spectrometry techniques to atmospheric chemistry.

Kevin Nihill, Postdoc

Education: B.S., Boston College 2011, Chemistry; Ph.D., University of Chicago 2017, Physical Chemistry
Contact: knihill @ mit.edu

Kevin began researching atmospheric chemistry at Boston College, moved into materials science through molecular beam surface scattering at the University of Chicago for his PhD, and has now returned to atmospheric chemistry at MIT. His research focuses on the reactivity of atmospheric organic radicals in various chemical environments, specifically by looking at reaction products of radicals in different phases.

Amanda Gao, Graduate Student

Education: B.S., Caltech 2018, Chemical Engineering
Contact: aggao @ mit.edu

Amanda is interested in using low-cost sensors to quantify atmospheric contaminants, and in applying novel data analysis techniques to draw useful conclusions from these measurements. Her undergraduate research at Caltech and NASA-JPL used computational techniques to model primitive atmospheres.

Mark Goldman, Graduate Student (co-advised by Bill Green)

Education: B.S., UT-Austin 2009, Chemical Engineering
Contact: goldmanm @ mit.edu

Mark is interested in studying mechanisms governing atmospheric oxidation of organic compounds. His work applies computational software to describe atmospheric conditions. He is developing Reaction Mechanism Generator software, which is primarily used to study high temperature reaction networks, to deal more accurately at lower conditions. Along with oxidation of gas phase particles, he also looks at how the oxidation products form into organic aerosols.

David Hagan, Graduate Student

Education: B.A., Hendrix College 2011, Chemical Physics; B.S., Washington University, Chemical Engineering
Contact: dhagan @ mit.edu

David’s current research focuses on the development of low-cost, low-power sensors to better characterize carbon-containing emissions. Prior to joining the Kroll group, he spent two years at Washington University in St. Louis developing the Volatility and Polarity Separator (VAPS).

Christopher Lim, Graduate Student

Education: B.S., UC-Berkeley 2009, Chemistry
Contact: cylim @ mit.edu

After graduating from Berkeley, Chris took a short break from school to work at Nanosys, a start-up that makes quantum dots for use in LED displays. He arrived at MIT in 2013 and is currently studying the role of multifunctional organic compounds in aerosol formation.

Josh Moss, Graduate Student

Education: B.S., UC-Berkeley 2014, Chemical Engineering
Contact: joshmoss @ mit.edu

Josh's research has focused primarily on determining whether current gas-particle partitioning models accurately describe atmospheric aerosol partitioning. Partially to this end, he has developed a simple model for identifying chemical properties of SVOC's using basic mass spectrometry. He is also very interested in better understanding the organic chemistry of the atmosphere, especially pertaining to aerosol formation and partitioning.

James Rowe, Graduate Student

Education: B.S., Georgia Tech 2017, Chemical Engineering
Contact: jcrowe @ mit.edu

James completed his undergraduate degree at the Georgia Institute of Technology, where he studied atmospheric chemistry through undergraduate research opportunities. His undergraduate work concerned characterizing aerosol formation under different atmospheric conditions through field studies. His research interests include instrumentation, the chemical evolution of toxic species in the atmosphere and their effects on public health, and global development.
