The Pollen and Aerobiology Research Group (PARG) aims to promote multidisciplinary research on all aspects involving bioaerosols, from their source to their impact.

Group Lead: Professor Carsten Ambelas Skjøth

About the group

The mission is to understand the formation, release, transport, transformation and removal of bioaerosols in the atmosphere and how this affects the general environment.

The application of the research is mainly within three areas of distinction: 1) human health & exposure coving topics such as pollen forecasting and palynology in relation to crime scenes and honey characterization; 2) plant health & food security covering topics such as crop diseases and invasive species, 3) Atmospheric processes topics and detection of bioaerosols covering topics such as eDNA and real-time detection using lasers. The method to carry out research are a combination of detection and mathematical modelling, often involving field work, laboratory work and use of computer clusters within a BIG data environment.

Current Research

Project titlePhenology of grass flowering at the species level (3 year PhD studentship supported by European Commission through a Marie Curie Career Integration Grant, University of Worcester and National Environmental Research Council).

Details: Our PhD student Carl Frisk has been working on observing grass pollen phenology, grass pollen concentrations and developing novel mechanistic modelling approaches based on Markov Chain Modelling and the HYSPLIT model. He will finish in Spring 2021.

Project titleDetecting spatial and vertical concentrations of fungal spores in the atmosphere using bioinformatics and drone technology (3 year PhD studentship supported by European Commission through a Marie Curie Career Integration Grant and University of Worcester).

Details: Our PhD student Godfrey Apangu has been working on Alternaria using both eDNA approaches as well as traditional aerobiological approaches using optical microscopy. He has combined this with vegetation studies and atmospheric modelling using HYSPLIT. He will finish in summer 2021.

Project titlePollerGEN: Linking grass pollen biodiversity and human health: an environmental genomics approach. Funded by National Environmental Research Council with £1.2m to Bangor University, Aberystwyth University, University of Exeter, University of Worcester, University of Sydney and the UK Met Office...

Details: We aim to revolutionise the way that pollen is measured, model spatial and temporal deposition from different species of grass pollen and identify linkages to human health.

Project titleADOPT: COST Action CA18226 - New approaches in detection of pathogens and aeroallergens. Supported by the European Commission with up to 700kEuro during the period 2019-23

Details: This COST action will establish an interdisciplinary network of experts currently involved in the detection of bioaerosols using both existing methods as well as upcoming technologies such as real or near real-time technologies from atmospheric chemistry and physics or eDNA methods used in molecular biology.

Project title: AUTOPOLLEN: An EUMETNET programme supported by the participating parties and the EUMETNET programme

Details: The AutoPollen brings together a consortium from across Europe with the multidisciplinary expertise needed to address the challenges along the entire information chain – from the actual observation through to the final end-user defined product by using automatic and real-time detection of pollen.

Current Opportunities

PhD
Fully-funded PhD studentships with PARG will be advertised here, but also on http://www.jobs.ac.uk/.

Approaches from self-supporting PhD students interested in the area of PARG are accepted all year round, typically with a starting time 01 October or 01 February. Please contact Professor Carsten Ambelas Skjøth for an informal discussion. PhD proposal can cover areas such as immunology and airborne allergens, atmospheric modelling of pollen or spores, eDNA and classification of pollen & spores, human exposure assessments, ecological aspects relation to bioaerosols and much more

Travelling grants

Scientists and PhD students associated with the COST Action ADOPT are eligible to apply for so-called Short Term Scientific Missions, where the award is up to 3500Euro. This funding can be used to visit the team or used by team members, in particular PhD students and post docs, to visit other outer laboratories in other countries.

Secondments and other long term stays

The team is regularly having international visitors over longer periods, often funded by international or national research grants or UK based funding bodies such as the Newton foundation, The Royal Society or the Welcome Trust.

Facilities

The team has one of the most advanced monitoring stations in Europe in relation to collection of bioaerosols as a large selection of equipment that may be used for field studies on bioaerosols. It runs advanced laboratories designed for studies on bioaerosols and operates a powerful computer cluster designed for modelling with large data in statistics, bioinformatics, remote sensing and the atmospheric models HYSPLIT and WRF-Chem.
