Justin Wheat is an MD/PhD student at the Albert Einstein Medical Centre in New York, USA. His expertise is in DNA transcription factors, how these influence haematopoiesis, and how they go wrong in leukaemia. We talk about the genesis of leukaemia and how transcription is at the heart of it, touching on well known transcription factors such as RUNX1, GATA1 and GATA2. Justin is a really good orator, and can explain difficult concepts really well.
