Swen is a researcher and entrepreneur. He studied Physics and Chemistry at the Universities of Heidelberg and Hamburg (Germany), Townsville (Australia), Utrecht (The Netherland - PhD in 2000). He has been a Max Planck researcher for many years, Head of the working group „Fuel cell development“ at Fraunhofer ISE in Freiburg i.Br. (Germany), Adjunct Associate Professor at The Cyprus Institute in Nicosia, and Partner at the digitalconcepts.io ag in Basel (Switzerland). He is founder of the start-up ResearchConcepts io GmbH (Freiburg i.Br.) and AFB SolarTec Ltd (Nicosia).

Since 1997 his research has focused on the modelling of aerosol multiphase chemistry, aerosol-cloud interactions with emphasis on air pollution feedbacks on weather and climate through aerosol hygroscopic growth (aerosol water). To enable the air pollution-aerosol-water-cloud-radiation coupling in regional and global climate models, he has developed a novel since fully analytical gas-aerosol partitioning model (EQSAM, Metzger et al., 1999, 2000, 2002, 2006, 2007, 2012, 2016, 2018), which he has extended by a comprehensive aerosol dynamical model (GMXe). GMXe has been introduced with Pringle et al. (2010), but originally developed as part of Metzger et al. (2007).

GMXe is used for instance in the recent CMIP6 AerChem MIP climate modeling studies (https://redmine.dkrz.de/attachments/download/3494/Kunze_CMIP6-AerChem-MIP-EMAC_2017-10_v4.pdf). AerChem MIP is an Aerosols and Chemistry Model Intercomparison Project that aims to quantify the climate and air quality impacts of aerosols and chemically-reactive gases in the climate models that are used to simulate past and future climate (https://www.wcrp-climate.org/modelling-wgcm-mip-catalogue/cmip6-endorsed-mips-article/1057-modelling-cmip6-aerchemip).

Both codes are meanwhile widely used by modelers around the globe. For instance, EQSAM is used at ECMWF (C-IFS, e.g., Flemming et al., 2014, 2015), DLR/EMAC (e.g., Lauer et al., 2005, Kaiser et al., 2014), NASA/GISS (e.g., Bauer S. et al., 2007a, 2007b, Bian et al, 2017) -- see e.g. Table 1 of Metzger et al., 2018 for an overview (though listing is not complete).

His most recent version, EQSAM4clim, was recently implemented and successfully tested in the EMEP MSC-W model (Tsyro et al 2019, https://emep.int/publ/reports/2019/EMEP_Status_Report_1_2019.pdf).

EQSAM4clim h as been further successfully applied in the Comprehensive Air quality Model with extensions (CAMx), which is maintained by the Ramboll group, see e Springer Publikation "Comparing the ISORROPIA and EQSAM Aerosol Thermodynamic Options in CAMx" (First Online: 24 November 2019, (https://link.springer.com/chapter/10.1007/978-3-030-22055-6_16).

Besides his EMAC/EQSAM/GMXe model development (as part of ECHAM/MESSy), he was also working with widely used numerical weather prediction (NWP) models, i.e., COSMO-DE of the German Weather Service (DWD, http://www.cosmo-model.org/content/consortium/generalMeetings/general2007/wg3/metzger_aerosols.pdf).
and more recently he was working with WRF-Solar.

Last but not least he is looking into cheap solutions for renewable energy storage, since his core expertise, which is on the absorption of water molecules by electrolytes (salt solutions), is also crucial for the development of superior redox flow batteries.
