2013-2016: PhD in Biotechnology, Heriot-Watt University, Edinburgh, UK
2009-2013: BSc (Hons) in Cell and Molecular Biology, Heriot-Watt University, Edinburgh, UK

I am a PhD student in Dr. Helen Bridle's research group - The Microfluidic Biotech group. The research conducted in this group constitutes interdisciplinary science focused mainly on the sample processing, recovery, treatment and detection of waterborne pathogens. Specifically, I work on the development of microfluidic systems for the species-level detection and viability determination of waterborne pathogens. Particular areas of interest include Microfluidic Impedance Cytometry, Deterministic Lateral Displacement, Acoustofluidics, Dielectrophoresis and Microfluidic-enabled Force Spectroscopy. Prior to commencing a PhD, I completed an undergraduate degree in Cell & Molecular Biology but also have industrial experience in Food and Water Microbiology and Mechanical Engineering. Outside of University, I enjoy playing guitar, badminton and soccer, and going cycling, running, hiking and travelling.
