Dr Kate Gardner is a consultant haematologist at Guy’s and St Thomas’ NHS Foundation Trust with a specialist interest in red cell disorders. She was awarded a PhD in 2017 during her Clinical Research Fellowship where she investigated the genetic basis of clinical variability in sickle cell disease. She has published both molecular research and clinical reviews in haemoglobinopathies. She has given talks internationally on sickle cell disease. Kate is also involved with clinical trials in sickle cell disease. She is continuing her research interest in the underlying genetics of sickle cell disease in an attempt to identify why some people are more severely affected than others – and, hopefully, novel molecular insights into sickle cell disease could drive new therapies.
