I am a stem cell scientist working on the biology of human embryonic stem cells and their differentiation into cells of mesodermal (blood, endothelium and cardiomyocyte) and endodermal (pancreatic islet cells) lineages.

Summary
We have different types of infection-fighting white blood - the soliders of the immune system. They can all grow from a single stem cell like a seed grows into a tree. So, by understanding this complex process, new and better therapies for cancer, organ transplantation and infectious disease are constantly emerging. I aim to use a cutting-edge technology called ‘cellular barcoding’ to answer some of the age-old questions about how stem cells grow into white blood cells.
Tailoring Dendritic Cell Diversity To Advance Effective Immunotherapies

Summary
Dendritic cells (DCs) constitute the first line of defense against infection and cancer. To achieve this feat, DC have evolved into a sophisticated network of specialized subtypes, although how this diversification process occurs is yet to be fully clarified. We have uncovered a new molecule, termed DC-SCRIPT, which has a key role in establishing the DC network, specialization and function. This offers crucial new clues as to how to manipulate DCs to either boost or dampen the immune system.

Summary
The cellular and molecular events that underpin metabolic syndrome diseases, such as diabetes, fatty liver, etc are poorly understood. However recent advances provide new clues. First, the immune system is intimately connected to metabolism. Second, the gut microbiota, and its metabolites such as acetate and butyrate are also important. These metabolites induce epigenetic changes in cells. We will study how metabolites induce molecular changes epigenetically, and how this controls metabolism.
Dendritic cells are essential components of our immune systems. They are located throughout our body and provide the first line of defence against invading microbes. Dendritic cells sense the invader and send out signals to recruit our immune cells to the site of infection. Our research aims to understand how our dendritic cell network is set up and how it functions to promote our immune health.
Dendritic cells (DCs) are the body’s sentinels, with three specialized subtypes. They monitor for infections and cancer and then activate immune T cells to clear it. Interestingly, they can all arise from a single cell, but the precise steps are unknown. By literally filming this process and analyzing the movie, we hope to draw the ‘family trees’ that lead to their generation. This knowledge will offer crucial clues as to how to boost or reduce their numbers for medical applications.

Summary
Vaccines invoke immune responses that will protect a vaccinated host if they encounter infection. Vaccines can also be deployed to fight cancer. 'Dendritic cells' are the key immune cell responsible for vaccine immunity. While dendritic cells are pivotal to initiating vaccination, little is known about their internal machinery. This research proposal will identify new machinery for dendritic cell vaccine immunity that will serve as therapeutic targets to boost vaccination.

Summary
Dendritic cells (DCs) are a blood cell type with a crucial role in our immune system. They are made in the bone marrow from stem and progenitor cells. How each of these cells individually makes DCs is complex and dynamic. We seek to understand this using cutting edge technologies to track each cell’s step-by-step role in this important process. This knowledge may help the use of DCs in the treatment of several diseases including autoimmunity and cancer.

Summary
The immune system can discriminate between invading microorganisms and the body's own tissues. Dendritic cells are specialised to alert the immune system in the case of infection. In this project we aim to understand how dendritic cells are generated and how they function to control the immune response. We will achieve this aim by using state of the art genomic technologies to describe the genetic programme of dendritic cells.

Summary
Dendritic cells (DCs) are a type of white blood that kick-start immune responses. There are various types of DCs that specialize in, for example, clearing viral, bacterial or fungal infections, and are even used to fight cancer. Understanding how DCs grow, therefore, has many clinical benefits. This project aims to understand these processes and identify new regulators of their growth using cutting edge technologies and strategies.
