Research summary

The research in our laboratory focuses on the processes that establish cell diversity and pattern in the early embryo. We ask the questions: how do cells in the embryo know what fates to adopt, at the right positions and at the right time? What mechanisms ensure that the correct proportions of cells are allocated to different organs?

Currently, the projects in the lab fall into four major headings:

1. How do higher vertebrate embryos establish their polarity, and what mechanisms coordinate cell movements with gene expression?

2. What mechanisms are responsible for inducing the early nervous system?

3. How is the early nervous system subdivided into forebrain, midbrain, hindbrain and spinal cord?

4. Embryonic stem cells - where are they in the embryo, and can we harness them to understand developmental pathways?

We are particularly interested in discovering mechanisms that represent general principles in development, and therefore follow a multi-disciplinary approach. We choose (or if necessary, develop) techniques that will help us best to answer the questions being asked, rather than being wedded to any particular set of techniques. We do not define our questions based on specific genes, but rather based on the biological event we are trying to understand + we first define the biological process and then try to establish which genes are important for that process. Finally, although much of our research uses chick embryos (because they are easy and cheap to obtain at precise stages of development, because it is easy to manipulate cells, and because a lot is already known about how they develop), we are also not wedded to this as an experimental system. Current projects use chick, quail, frog and mouse embryos, and we are also collaborating with other labs using yeast, flies and fish.
