Interested in prebiotic chemistry? We are currently looking for graduate students and postdocs to work on new autocatalytic reactions and prebiotic chemistry. 

Interested DPhil students should apply to the department and be EU citizens.

A Postdoctoral position is advertised here

We are a synthetic organic chemistry group – we develop new catalytic asymmetric methods for synthesis.  We also building model systems to study and understand important processes in chemistry and biology.  Our current efforts can be roughly divided into the following areas.  

1. Asymmetric catalysis

We are developing methods for catalytic asymmetric C-C bond formation.  There is a real need to develop new methods that use simple and readily available starting materials to make complex molecules.  The emphasis of these studies is on developing new, fast, efficient and powerful methods. 

2. Origins of life

The origins of life are not well understood and this is one of the great questions in contemporary science. In this respect we are designing self-replicating systems and autocatalytic reaction networks that may be relevant to prebiotic chemistry.

3. Conversion of light into energy

The molecular prerequisites governing the conversion of light into mechanical energy are poorly understood.  How to control this energy, and what it can be used for are also poorly understood.
