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 works include remediation of PAC-contaminated soils, chemical analysis and exposure screening of neutral/volatile PFAS found in consumer products, analysis of neutral/volatile PFAS potential transdermal uptake from the gas phase, and preliminary risk assessments of neutral/volatile PFAS.

I am a big proponent of healthy work-life balance and am a big believer in the importance of mental health. I enjoy going to spin classes after work as a way to recharge during the week, while also utilizing available mental health supports. On weekends, I appreciate hiking/walking in nature, listening to music, meal prepping for the following week, or watching Arsenal matches on TV.

Research Interests and Expertise

  • PACs in sealcoat and in soil
  • Volatile/neutral PFAS in consumer products and in air
  • Applications of computational predictions and chemometrics in environmental chemistry
  • Suspect screening and non-targeted analyses using GC-high resolution MS
