Dr. DeWitt joined MIT in early 2015 to assume the role of Station Chief Scientist for the Rwanda Climate Observatory. She is an analytical chemist with a specialty in mass spectrometry and a focus on the analysis of aerosols (particles or liquid suspended in air—e.g., smog; dust; sea salt), from laboratory-simulated aerosol mimicking those potentially present on the Archean Earth and Titan to in-situ aerosol sampled in remote marine locations to anthropogenically-influenced aerosol sampled adjacent to a major highway.
