Welcome to the Bzdek Research Group!
We use single particle mass spectrometry and optical trapping approaches to investigate fundamental questions about aerosols in environmental and industrial contexts.
Our paper on aerosol generation during woodwind and brass instrument playing has been published in Aerosol Science and Technology! The main takeaways are that the aerosol coming out of an instrument is consistent with that produced by the performer while breathing and that the amount of aerosol generated is determined by the performer, not the instrument. This is one of a series of papers we have published exploring aerosol generation during respiratory procedures and in clinical settings to address the current pandemic.
We are pleased to welcome two new senior researchers into the group: Dr Alison Bain and Dr Jim Walker!
We are pleased to announce that we have received funding through the European Research Council to investigate the surface properties of microscopic aerosol droplets! This funding will allow our group to grow through recruitment of two new postdoctoral research associates and through acquisition of a mass spectrometer! More information on the project can be found here!
Our paper on aerosol generation from intubation and extubation procedures in clinical settings was published in the journal Anaesthesia! The aim is to quantify aerosol generation in order to make evidence-based decisions about the risks associated with these procedures.
In response to the COVID-19 pandemic, we have begun working with the local hospital system to investigate aerosol generating procedures, which are thought to emit aerosol and therefore require enhanced PPE and long waits between procedures. However, the evidence base for this risk is lacking. We will be making measurements in hospitals to quantify aerosol produced by these procedures. More information on the project can be found here. This work is funded through a grant from UKRI/NIHR.
In response to the COVID-19 pandemic, we have been spending several weeks working with professional singers and musicians in London to quantify aerosol emission during singing, speaking, and breathing. The work got picked up in the news media. Click here to read more about the study!
Bryan was interviewed for Big Picture Science, a public radio show produced at the SETI Institute in California, about aerosol transmission of SARS-CoV-2. You can listen to the show here!
Our paper on the surface tension of aerosol droplets is published in Proceedings of the National Academy of Sciences!
We welcome PhD student Joshua Harrison to the group!
We perform a field campaign to investigate the air quality in a local Victorian house. This work was done in collaboration with Dr Dan Schien in Computer Science and with Dyson.
Our group’s first research paper is published in the Journal of Physical Chemistry A!
Our Scanning Mobility Particle Sizer is delivered. We thank EPSRC for the funds to acquire this instrument, which allows us to measure ambient particles down to 2 nm diameter! This instrument will support our growing laboratory.
We hosted a successful workshop on Indoor Air Quality, which was sponsored by GW4 and attended by researchers from Bath, Bristol, Cardiff, and Exeter, along with representatives from public agencies and industry!
Our group is awarded funds to study indoor air pollution through the GW4 Alliance. This is a collaborative project involving researchers at Bath, Bristol, Cardiff, and Exeter.
MSci student Lara Lalemi secures a PhD studentship through the NERC GW4+ Doctoral Training Partnership to start in September. Congratulations, Lara!
Our invited perspective on grand challenges in the chemical physics of aerosol is published as the cover article in this week’s issue of the Journal of Chemical Physics!
Bryan receives the 2017 Sheldon K. Friedlander Award from the American Association for Aerosol Research Conference in Raleigh, North Carolina. The award recognises an outstanding dissertation by an individual who has earned a doctoral degree.
