Biography

My research primarily focuses on understanding the ecological drivers of tick-borne diseases to provide insights on the mechanisms involved in transmission cycles, especially on the interactions between ticks, hosts and pathogens. My research includes investigating the impacts of environmental changes (woodland restoration, rewilding) and host community composition (deer, rodent and birds) on tick-borne diseases risks in the UK.

Experience

Research Associate

University of Glasgow

March 2026 – Present Glasgow, UK

I am currently a research associate within the University of Glasgow, working on the FarmAquaNet project. This One Health Framework aims to assess the risks of antimicrobial resistance in aquatic ecosystems in northereast Thailand, in collaboration with Kasetsart University, Chulabhorn Research Institute, Stirling University, Chiang Mai University and Mahasarakarm Universiy. I am currently leading the design of stated choice experiments to assess and quantify willingness to reduce antibiotic usage in aquaculture.

Research Associate

University of Glasgow

March 2024 – January 2026 Glasgow, UK

I was a research associate at the University of Glasgow, working on the MEaSURE project, an interdisciplinary project in collaboration with the University of Manchester and the University of Salford. The project aimed to explore the ecological services and disservices associated with urban green spaces. My research specifically focused on investigating ecological and socioeconomic drivers of tick-borne disease hazard and Lyme disease incidence in urban greenspaces.

Senior Medical Entomologist

UK Health Security Agency

March 2023 – February 2024 Porton Down, UK

As a Senior Medical Entomologist, I was leading a range of ecological research projects, including the National Tick Survey as well as various field base ecological project investigating the impacts of land management and host presence on tick-borne disease hazard. I also analysed large government dataset to understand spatiotemporal changes in tick distribution. Some of my responsibilities included:

Managing field base ecological research projects
Coordinating with stakeholders and project partners
Management of data entry
Data analysis (data visualisation, statistical modelling, spatial modelling)
Writing peer-reviewed articles
Training vector control officers overseas (UKOTS)

Medical Entomologist

UK Health Security Agency

March 2020 – March 2023 Porton Down, UK

As a Medical Entomologist, I was involved in a range of ecological research projects focusing on better understanding tick-borne disease risk in the UK. Some of my responsibilities included:

Coordinating field work logistics, leading a team of 5 people
Coordinating with stakeholders and project partners
Data entry
Data analysis (data visualisation, statistical modeling, spatial modelling)
Writing peer-reviewed articles

Graduate teaching assistant

University of Glasgow

November 2016 – May 2020 Glasgow, UK

As a graduate teaching assistant, I was teaching undergraduate and MSc students during practicals and tutorial sessions on general biology (labs & marking), introduction to GIS, statistics (GLMs, GLMMs, dplyr & ggplot2 in R), marine biologgy (field course) and molecular biology (labs).

PhD Candidate

University of Glasgow

October 2016 – September 2020 Glasgow, UK

My PhD focused on the impacts of host community composition on Lyme disease hazard in Scottish woodlands.

Field technician

Grimsö research station

May 2016 – July 2016 Grimsö, Sweden

As a field technician, my duties included mammal capture (roe deer, rodents), blood sampling, radio-telemetry, animal survey, tick collection, tick identification and distance sampling.

MSc research project

Grimsö research station

January 2015 – August 2015 Grimsö, Sweden

My research project focused on understanding the influence of time, temperature and humidity on Ixodes ricinus density in Sweden using a long term dataset.
