Viral Entry and Vaccines
We conduct studies into 3 of the world’s most destructive human pathogens: SARS-CoV-2 (COVID-19 virus), HIV and hepatitis C virus.

About
Focusing on the COVID-19 virus (SARS-CoV-2), hepatitis C, and other significant viruses, we study how viruses enter cells and how the immune system can block infection. Using structural biology, immunology, and vaccine design, we develop strategies to prevent viral infection. This includes creating next-generation vaccines and understanding protective immune responses.
Our research focuses on understanding the molecular mechanisms of viral entry and the immune responses that can prevent infection. To inform the rational design of vaccines, we use a multidisciplinary approach combining:
- structural biology
- virology
- protein engineering
- systems immunology.
A major focus of our work is hepatitis C virus (HCV), one of the most genetically diverse viruses, and SARS-CoV-2, the virus responsible for COVID-19. Both pathogens pose significant challenges for vaccine development due to their ability to evade immune recognition.
By investigating how antibodies and T cells respond to infection or vaccination, we aim to define the key features of protective immunity. This knowledge guides the development of next-generation vaccines capable of inducing broad and durable protection.
Our vaccine candidates are tested in preclinical models to evaluate safety and immunogenicity. The goal is to progress to human clinical trials for real-world impact against these and other emerging viral threats.

Current projects
View 4 moreImmunity to SARS-CoV-2 post-vaccination and infection in people who live without a functioning spleen
We aim to understand how living without a functioning spleen impacts a person’s antiviral immune responses to viral infections and vaccination.
Understanding the impact of hyposplenism on the immune system
This project identifies immune impairments in people living with hyposplenism.
Immunity to SARS-CoV-2 post-vaccination and infection in people who are immunosuppressed
The aim of this project is to profile the immune response to COVID-19 vaccination in people who are immunosuppressed.
Past projects

COVID-19 antigens for PoC test development
In this project we will express both the spike and nucleoproteins of COVID-19 and other coronaviruses. These antigens will contribute to the development of a COVID-19 point-of-care diagnostic test.

Neutralising antibody assays for COVID-19
Rapid high-throughput neutralisation assays are essential for analysis of immune responses in human infection and animal experiments.

ACE2 inhibitors for treatment of COVID-19
We aim to contribute to the development of an antiviral inhalant for patients with Acute Respiratory Distress Syndrome caused by SARS-CoV-2 infection (COVID).
