Michael’s research interests revolve around studying the chemical composition of carbonaceous aerosols, and currently leads the development of the VAPS instrument. He has performed laboratory studies in the ACT lab utilizing the PAM oxidation chamber, as well as at Georgia Tech using an Environmental Chamber in collaboration with Dr. Nga Ng. He has performed field studies at East St. Louis, IL, at Jefferson St. Station in Atlanta, GA, and two indoor/outdoor field deployments at residential homes in St. Louis. In addition to instrument development, Michael has worked to advance our methods to employ Positive Matrix Factorization on a wide range of datasets and to archive our chemical source profiles from lab and field observations.
Audrey Dang - PhD 2023 - NSF Graduate Fellow
B.E. Chemical Engineering '14, Vanderbilt University
Audrey currently works on the development and deployment of lower-cost and portable air sampling instrumentation. She has collaborated with WashU's Institute for Public Health and industry partners Aerodyne Research Inc. to deploy off-grid gas and particle monitors in Cap-Haitien, Haiti. Audrey has been the lead developer of the MOIRA VOC monitor and has tested the instrument for indoor air sampling and mobile monitoring from a hybrid vehicle. During lab shutdowns caused by the COVID-19 pandemic Audrey performed emergency operation experiments to test filtration performance of improvised mask designs for health care workers.
