Profile
Summary: 

Zak works on the physical and chemical modelling of atmospheric aerosol as part of the Copernicus Atmosphere Monitoring Service (CAMS). This includes both developing new approaches to improve these parameterisations and their coupling with other parts of the IFS, and integrating improvements developed by our external partners.

Professional interests: 
  • Aerosol modelling
  • Aerosol–chemistry interactions
  • Removal processes, especially wet deposition by cloud and precipitation
  • Air quality impacts
  • Feedbacks on cloud, radiation and climate
Career background: 

2016–present Scientist at ECMWF in CAMS Development Section.

2013–2016 Post-doc at the University of Oxford in Atmospheric, Oceanic and Plantary Physics, working on aerosol–convection interactions in global models as part of the ACCLAIM project.

2008–2009 M.Sc. at the University of Reading in Mathematical and Numerical Modelling of the Atmosphere and Oceans (Departments of Mathematics and Meteorology). Dissertation title "Error growth in medium-range forecasting models", supervised by Andrew Charlton-Perez and Cristina Primo (ECMWF, now DWD).

2002–2008 Software Engineer at Transversal, Cambridge.

1998–2001 BA (Hons) at the University of Cambridge (Girton College) in Mathematics.
