I am an environmental chemist with expertise in the analysis of organic pollutants, namely polycyclic aromatic compounds (PACs) and per- and polyfluoroalkyl substances (PFAS), using gas chromatography and mass spectrometry (GC-MS). I complement my experimental approach with computational methods, primarily relying on density functional theory (DFT) calculations.

Outside of the lab, I enjoy cooking, traveling, hiking/walking in nature, and listening to music. I am also a big fan of Arsenal F.C. and San Antonio Spurs.

Research Interests and Expertise:

  • PACs in sealcoat and in soil
  • Applications of computational predictions in environmental chemistry
  • GC-MS based suspect screening and non-targeted analyses
  • Thermal desorption (TD)-GC-MS applications to analyze organic contaminants
  • Volatile/neutral PFAS in consumer products and in the environment

Ongoing Research Projects:

  • Development and application of a method to analyze volatile/neutral PFAS in gas-phase using TD-GC-MS
  • Prediction of PFAS electronic properties using DFT calculation and of PFAS physical-chemical properties using SPARC
  • Measurement of volatile/neutral PFAS in consumer products and in environmental samples
  • Analysis of total and freely dissolved PACs in soil pre- and post-steam enhanced extraction remediation
