2023-24 Cohort

Our fifth cohort of 22 students started their PhD studies in September 2023. Find out more about their interests and research projects below.

Phoebe French - Imperial College London

Project: The impact of environmental conditions on the prevalence and aerosol transmission of Streptococcus pyogenes

Supervisors: Dr David Green, Prof. Shiranee Sriskandan

Before starting the CDT programme, Phoebe completed her undergraduate studies in Biochemistry at the University of Reading. She developed an interest in bioaerosols whilst on industrial placement with the UKHSA.

Her PhD will focus on developing an understanding of how pollutants and other environmental conditions affect the aerosol transmission and prevalence of Streptococcus pyogenes. This bacterial species is the cause of scarlet fever, a disease that has had a resurgence in recent years due to currently unknown factors.

Oscar Zhang - University of Leeds

Project: Improving Aerosol and Spray Process Computational Fluid Dynamics Models with Machine Learning Approaches

Supervisors: Prof. Andrew Bayly, Prof. Peter Jimack, Dr Joseph Ghaffari Motlagh

I completed my undergraduate studies in physics in both Ireland and China. Subsequently, I pursued a Master’s in Material Science in the UK. Currently, I am working on applying Physics Informed Neural Networks (PINNs) to Computational Fluid Dynamics (CFD) models of aerosols and sprays. The aim of my research is to enhance CFD models with multiple particles present to capture the complex physics involved in drying and solid formation. These improved models will then be integrated into a CFD model of a spray drying tower, and their performance will be thoroughly assessed.

Charlotte Reston - University of Bristol

Project: Investigation of novel methods to study the survival of foot-and-mouth disease virus in aerosols

Supervisors: Prof. Jonathan Reid and Dr Claire Colenutt

My undergraduate degree was an integrated Masters programme in Virology and Immunology in the school of Cellular and Molecular Medicine at the University of Bristol. This involved working with influenza A, coronavirus 229E, Pneumonia Virus of Mice, Respiratory Syncytial Virus, and SARS-CoV-2, investigating entry mechanisms into cells and RNA modifications to genomic material.

Xiaojie Sun - University of Bath

Project: High-dose antibiotics inhalers for acute lower respiratory tract infections in primary care

Supervisors: Dr Bernardo Castro Dominguez, Dr Matthew Jones, and Dr Albert Bolhuis

Xiaojie completed her Master’s degree in Pharmaceutics from China Pharmaceutical University, where she developed research interest in Crystal Engineering, focusing on investigating the impact of solid-state crystalline forms on the properties of pharmaceutical formulations. After graduation, she pursued a career in industry, committing to exploring the influence of solution crystallization process of APIs on the crystal form, particle size and purity. Since strong interest in academic research, she decided to pursue her PhD.

Xiaojie’s PhD program at University of Bath will integrate Aerosol Science with Crystal Engineering to generate inhaled high-dose antibiotic micro/nanoparticles, suitable for the management of lower respiratory tract infections.

Xia Yi - University of Bristol

Project: Transmission of Bacterial Resistance Genes in Aerosols

Supervisors: Prof. Jonathan Reid and Dr Allen Haddrell

Xia worked on correlation analysis of cryptosporidium in calf bedding and calf diarrhoea during her undergraduate degree in the College of Veterinary Medicine from Nanjing Agricultural University. With a great passion for animal health management, she got a master’s in the College of Veterinary Medicine from China Agricultural University which she focused on the effects of dietary fibre on the intestinal health of preweaning calves and investigated the Antimicrobial Use and Antimicrobial Resistance in Pathogens Associated with Diarrhoea and Pneumonia in Dairy Calves. Through 7-years of veterinarian study, she has an appreciation that disease prevention takes precedence over treatment in ranch animals’ health management and the importance of zoonoses to humans and animals. So this led she wants to study the transmission of pathogens in aerosols, to contribute to the ranch animals’ health and the public health simultaneously.

Xia started a PhD in bioaerosol, where she will be characterizing the environmental parameters that related to gene transfer can occur in bacteria when contained in aerosol droplets, leading to AMR bacteria.

Toyosi Akande - University of Hertfordshire

Project: Dry water for future inhaled medicines

Supervisors: Prof. Darragh Murnane

I completed my undergraduate degree in Biomedical Science at the University of Brighton, and a master’s degree in biomedical research at Imperial College London. During this time, I developed an interest in the bioreactivity of inhaled particles on lung alveolar cells. This interest grew and made me apply for a PhD once I completed my master’s.

This paved my path to joining the CDT in Aerosol Science carrying out a PhD, where I aim to explore dry water formulations for drug delivery of biologics such as proteins, whole cells, and RNA to the airways.

Joseph Bainbridge - University of Manchester

Project: Chemical and toxicological properties of aerosol emissions subject to atmospheric processing

Supervisors: Dr James Allan and Prof. Gordon McFiggans 

I graduated from the University of Nottingham with a Master of Science in chemistry, during which I developed an interest in atmospheric science which I decided to pursue through the CDT in Aerosol Science. My research project focuses on developing a protocol for the generation and quantification of secondary and aged primary aerosols using an oxidation flow reactor, applicable to a range of real-world sources. The chemical changes that occur and the toxicological properties of the aerosols will be studied and used to inform atmospheric chemical transport models and public health impacts of air pollution.

Before enrolling in the CDT, I completed my Aerospace Engineering (MEng) undergraduate degree at the University of Bristol (2019-2023). I was particularly interested in programming, modelling and simulations, leading me to apply for the project proposed by Dr Alberto Gambaruto.

My project focuses on establishing an exhaustive description of parameters influencing the resuspension of particles. I am very enthusiastic about using state-of-the-art experimental and numerical approaches such as wind tunnel testing and CFD, in addition to machine learning-based models (PINNs) to predict resuspension behaviour.

Kexin Qiu - University of Leeds

Project: Aerosol emissions from future generation aircraft and their impact on climate

Supervisors: Dr Alex Rap & Prof. Ben Murray

Growing up in a city with severe air pollution sparked my interest in aerosol research. During my undergraduate studies in Earth Sciences at UCL, I became particularly interested in the climate impacts of aerosol emissions after studying the climate dynamics. On my final year, I conducted a research on whether the reduction of aerosol pollutions will accelerate global warming. Through this experience, I became aware of the significant uncertainties associated with aerosol-cloud interactions when assessing aerosol climate impacts. As a result, my current PhD project is dedicated to quantifying the indirect climate impact of aerosol emissions i.e., aerosol-cloud interactions from current and future aviation. This is essential for gaining a comprehensive understanding of aviation’s complete climate footprint and for designing more informed emission pathways to achieve the aviation industry’s ambitious net-zero carbon target.

Nan Zhou - University of Bristol

Project: Hygroscopic dynamics of solution phase aerosol on generation and inhalation to the lungs

Supervisors: Prof. Jonathan Reid & Dr Rachael Miles

Nan graduated from the Australian National University with a bachelor degree of Medical Science. Then he obtained a master’s degree in Pharmaceutics from the University College London where he developed a strong interest in drug delivery to the lungs. Thus, he decided to join the Aerosol Science CDT and the Bristol Aerosol Research Centre (BARC) to continue his research. For his PhD, he will be studying the effect of hygroscopicity on the stability of dry powder formulations. He is excited to contribute to the development of more effective and reliable drug delivery systems for respiratory conditions.

Anushi Khandare - University of Leeds

Project: Optimising the performance of air cleaning technology for mitigation of infection in hospital environments

SupervisorsProf. Catherine Noakes, Dr Louise Fletcher, Dr Marco-Felipe King

I completed my BS-MS (dual degree) from the Indian Institute of Science Education and Research, Bhopal, India in the year 2023. I majored in Environmental Sciences where my thesis focused on finding the oxidative potential of PM 2.5 in Central India. This was the time where my interest in aerosol and health developed. I would be working on optimizing the performance of air cleaning technology for mitigation of infection in hospital environments. The aim would be achieved by a combination of experimental study and computational modelling. Experiments will involve sampling and culturing microorganisms from the air and on surfaces, as well as real-time measurement of physical environmental parameters . Modelling approaches based on Computational Fluid Dynamics (CFD) will be used to simulate the interaction of the air cleaning device with the airflows and pollutant sources in indoor spaces. This will build on existing chamber airflow CFD models with a device model added to understand interactions between the device and room airflow and the capture behaviour for different size aerosol particles as well as chemical species in air. The combination of CFD and experimental data will be used to assess aspects such as performance characteristics, optimisation of controls and the effectiveness under transient scenarios.
