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.

I am interested in the intersection between the environment, analytical chemistry and human (health), which leads me to works in the area of organic pollutants analyses in different matrices. Some of my past and current works include remediation of PAC-contaminated soils, exposure screening of neutral/volatile PFAS for transdermal uptake from the gas phase, and preliminary risk assessment of neutral/volatile PFAS found in consumer products.

I am a proponent of healthy work-life balance and believe in the importance of mental health.

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 and chemometrics in environmental chemistry
  • Suspect screening and non-targeted analyses using GC-HRMS

Ongoing Research Projects:

  • Analysis of volatile/neutral PFAS in consumer products and in the environment using GC-MS and thermal desorption (TD)-GC-MS
