Abstract I am currently a 4th year PhD candidate in Dr. Rob Griffin’s group at Rice University. My research focused on the sources and formation of O3 and non-refractory submicron particles (NR-PM1) in San Antonio and the temporal differences of the two criteria pollutants under varying meteorological conditions.
Funded by the Texas Commission on Environmental Quality, my collaborators and I deployed the Mobile Air Quality Laboratory to San Antonio for four weeks during May 2017, measuring O3, NOX, NOy, CO, SO2, NR-PM1 (with HR-ToF-AMS), VOCs (with PTR-MS and canisters), and meteorological parameters. I utilized the TUV Model and NASA Langley Research Center (LaRC) 0-D Box Model to quantify the diurnal variations in O3 production rate, efficiency (OPE), OH reactivity of VOCs, and O3 production regime across the city. Analysis of NR-PM1 data is performed using SQUIRREL and PIKA in Igor Pro, followed by Positive Matrix Factorization (PMF) for source apportionment on the high-resolution mass spectral, whereas aerosol liquid water content and pH are modeled using ISORROPIA-II. Cluster analysis and Weighted Potential Source Contribution Function (WPSCF) analysis are done with HYSPLIT to identify the regional sources of gaseous and particle pollutants. Furthermore, the relationship between local O3 production and SOA formation is evaluated and a Lagrangian analysis is developed to quantify the variations in composition and oxidation processes of organic aerosol across the city.
My anticipated graduation is May 2020. I am looking for a Postdoc researcher position in aerosol chemistry, especially field and lab studies emphasized on SOA formation and source apportionment using AMS or similar instruments. I am also interested in instrument development and the nexus between criteria air pollutants (e.g. PM and O3) and human health. I have no geographical preferences and am willing to travel for field campaigns.
