Teaching Responsibilities

I have assisted on marine biology and earth science field trips with 2nd year students to Southampton.


My main area of interest has always been into the Analytical chemistry of today and the vast techniques being used for detection especially detection of chemicals unwanted in today’s environment, this had led me on to my undergraduate Project  where I had looked into the degradation and migration  of Metaldehyde in Organic soil in which I gained the use of the analytical techniques of Fourier Transform Infrared spectroscopy, Inductively Coupled Plasma atomic emission spectroscopy and Gas Chromatography with flame ionised detection. I gained interest in this project as it is a hand on way approach for making the world a better place with new and improved analytical techniques.

PhD research project

Development of a passive sampler for monitoring sources and fluxes of metaldehyde in natural waters and response to stochastic storm events.

Metaldehyde is a widely used molluscicide in today agriculture; therefore it is important we follow its migration in the environment over time. Riverine contamination by metaldehyde can result in UK water companies breaching the Drinking Water Directive standard currently set at 0.1 μg L-1 Rivers routinely range from 0.2-2.0 μg L-1. Concentrations in lowland. In this project I will be using the analytical techniques of Liquid Chromatography coupled with a triple quadruple mass spectrometer to help determine the concentration of metaldehyde in natural waters using a variety of sampling techniques including the Chemcatcher®.
