Research Interests

My research interests are focused on the study of air pollution in Chicago as well as on analytical applications of total reflection X-ray fluorescence spectrometry (TXRF).

Air Pollution Studies in Chicago:

Our research investigates air pollution in Chicago and how lake breeze events influence transport and evolution of air pollutants. For this we collect aerosol samples with high temporal resolution and measure ozone and NOx mixing ratios at the Loyola University Chicago Air Station (LUCAS). The aerosol samples are analyzed for ionic and elemental species. The chemical fingerprints provide us with important information about evolution and transport of pollutant species in the region. We recently started to collaborate with researchers from the National Center for Atmospheric Research (NCAR) in order to apply the WRF/CHEM model to our measurement data and to explore the possibility of using remote sensing data to enhance our findings. 

Analytical Applications of TXRF:

We use TXRF for analysis of trace elements in various types of samples. TXRF is a powerful non-destructive ultra-trace analysis method and able to analyze particles or dried residue samples deposited on a smooth surface as well as impurities within surface layers. We routinely use TXRF for quantitative elemental analysis of atmospheric particulates either directly after collection onto filter and impactor substrates or after acid digestion of the samples. Currently we are in the process of expanding our range of applications into forensic analysis (glass, fiber and powder), thin film deposition, and catalysis. We also recently became involved in the NASA Genesis mission http://genesismission.jpl.nasa.gov/ by analyzing the return samples for surface contamination with TXRF.
