My research is aimed at understanding how the structure and dynamics of proteins dictates their function. I use X-ray crystallography to determine the shapes of proteins. Proteins are not static, however - they move in complicated ways, and often their motion is critical to their function (molecular motors, for example). It is very difficult to 'watch' this movement in the lab, so I use computer simulation to try to understand how proteins move.
Mechanisms Of Gene Regulation - Structure, Function And Design

Funding Amount

Summary
The human genome contains at least 20000 genes. The activity of these genes must be tightly controlled throughout an individual’s life and problems with the regulation of genes lie at the heart of many common and serious diseases, including most forms of cancer. My program of research is focused on understanding the mechanisms underlying gene regulation and on the design of new reagents that could be used to manipulate the activity of genes that behave aberrantly in disease states.
Structural Biology And Therapeutic Targeting Of Proteins Involved In Infection And Immunity

Summary
Structural biology plays an essential role in uncovering how proteins function at the molecular level, and further facilitates strategies to develop therapeutics targeting the diseases these proteins are involved in. In the proposed work, I will focus on bacterial virulence factors, to develop new antibiotics and vaccination strategies, and proteins involved in innate immunity pathways, to develop therapeutics against a number of associated disorders including chronic inflammatory diseases.
I am a biochemist focussed on understanding how the structures of proteins determine their functions. I intend to apply this understanding to medically relevant questions by working collaboratively and using a range of complementary structural, computational and cell biology techniques. In particular, I will focus on proteins involved in infection and immunity, to understand how they work, and contribute to the development of drugs and vaccines.
I am a structural biologist with a background in pharmacy. My research focuses on dissecting the molecular mechanisms of disease-causing proteins to underpin the development of new and improved therapeutics

Summary
Impaired cell death (apoptosis) is now recognized as an important step towards cancer and a major barrier to effective therapy. The discoveries on apoptosis by Professor Jerry Adams and colleagues have galvanized the search for drugs that engage the cell’s apoptotic machinery as a new way to treat cancer. His proposed studies aim to clarify how apoptosis is controlled and how the control goes awry in cancer, and to determine how such drugs can be most effectively used to improve cancer treatment ....Impaired cell death (apoptosis) is now recognized as an important step towards cancer and a major barrier to effective therapy.

Hepatitis C virus (HCV) and Human immunodeficiency virus (HIV) infect 200 million and 50 million people world-wide, respectively, and there are no preventative vaccines. The work outlined in this fellowship seeks to understand the structure and function of the major surface proteins of these viruses, their ability to be recognised by the immune system and to develop a novel vaccine for the prevention of HCV.
Peptides (mini proteins) have outstanding potential as new drugs for cancer, pain and many other diseases, but their potential has not been realised so far because peptides tend to be unstable in the body. I have discovered a new class of peptides that are ultra-stable and have very favourable pharmaceutical properties. I will use these peptides to develop a new generation of drugs that are more potent and with fewer side effects than traditional drugs.
