Exploring the Present and Past of the Earth's Atmosphere

The atmosphere is a multiphase environment in which gases, particles and fog/cloud droplets interact. The chemical reactions happening in this complex environment can change the composition and the reactivity of atmospheric components and therefore their effects on the Earth’s climate and on public health.

We use a multifaceted experimental approach, combining field measurements and laboratory experiments, to understand the evolution of particles in the atmosphere, and assess their effects on climate and on public health. We work on developing methods using advanced analytical tools, from high-resolution mass spectrometry to top notch microscopy and spectroscopy techniques, together with multivariate data analysis. We use the fundamental information on particle reactivity and composition to reconstruct past compositional changes of the atmosphere from analysis of organic biomarkers in ice cores.

My research interests are:

  • Coordination chemistry in atmospheric aerosols and cloud/fog droplets
  • Analysis of terrestrial and marine biogenic markers in ice cores for paleoclimate reconstruction
  • Source apportionment of atmospheric aerosol using receptor models
  • Indoor air quality
  • Greenhouse gases emissions

Diversity and inclusion statement

A multicultural and diverse research team is an asset to research excellence because it is fueled by different experiences, point of views and ideas. I value diversity and proactively encourage inclusion by creating a supportive environment and embracing the Athena SWAN principles. I promote and encourage a sustainable work/life balance and flexible working arrangements.

Joining the group

Prospective postgraduate students should apply through the Department of Chemistry Postgraduate Admissions. Prospective postdoctoral researchers are invited to apply for fellowships or to contact me for information on additional funding that may be available. Here is a short video about my work:
