Who am I?
• Haematology Consultant at University College London Hospital/Research at UCL CI

Why am I here
• Trained in Haematology in Glasgow and London• 2006 went to Harvard Medical School in Boston,
USA• Became interested in studying DBA

Researching what goes wrong in DBA – WHAT DO WE KNOW?
• Red blood cells die prematurely

Researching what goes wrong in DBA – WHAT DO WE KNOW?
•Mistakes or absence one copy of a group of genes•These genes code for ribosomal proteins

Researching what goes wrong in DBA – WHAT WOULD WE LIKE TO KNOW?
•Since ribosomes are needed in all cells, why does DBA only cause problems with red blood cells?
•Can we use research to help us find new treatments ?

How to answer our questions?
• Patients and their families are the greatest teachers
• Some experiments cannot be done on patients so we need to learn more using other laboratory models

Ongoing projects – using DBA zebrafish to find new drugs for DBA
Assess candidate compounds in primary cells
Use Red fluorescent DBA zebrafish
