Sammi Treagus

Postgraduate Research Student

 

Overview

I graduated from the University of Surrey in 2017 with a first-class degree in Biochemistry, which was a four year course with an industrial placement year. The industrial placement year was performed at CEFAS and involved molecular biology and microbiology techniques to enable estimates of viable norovirus in shellfish using a surrogate bacteriophage.

My interests lie within human disease, microbiology, virology and molecular biology.

Broad research specialisms

Molecular biology, microbiology, virology, biochemistry, phylogenetics, pathology

Qualifications

First-class BSc Biochemistry (Hons)

Research projects

Project Title: Zoonotic Transmission of Genotype 3 Hepatitis E Virus through the Aquatic Environment in the UK

Supervisors: Ben Longdon (UoE), James Lowther (CEFAS), Craig Baker-Austin (CEFAS)

Funding Body: CEFAS Seedcorn

Project Description:

My PhD is a project involving the detection and quantification of viruses within the aquatic environment, with a particular focus on Hepatitis E virus (genotype 3), an emerging zoonotic human pathogen within the UK.
