Professor Louis Chesler has both a private and an NHS practice at The Royal Marsden. He is working to develop new drugs for poor-outcome children's cancers that at present respond poorly to existing treatment. These cancers include the three most common solid tumours of children: neuroblastoma, a nerve tumour, rhabdomyosarcoma, a muscle tumour and medulloblastoma, a brain tumour.
He is an Honorary Consultant Medical Oncologist at The Royal Marsden and leads the Paediatric Solid Tumour Biology and Therapeutics within The Institute of Cancer Research's Clinical Studies Division.
South African-born Professor Chesler completed his early scientific and medical training in the United States, taking his Bachelor of Science (Honours) at the University of Wisconsin-Madison and his MD and PhD at Northwestern University and Medical School in Chicago. During this time he also worked for the US government’s National Institute of Health and National Cancer Institute as an Intramural Fellow.
In 1995, he joined the University of California, San Francisco, working as a paediatric oncology consultant and running a neuroblastoma research programme, before moving to the ICR in 2007 as a Senior Clinical Lecturer.
Professor Chesler is a member of the American Association for Cancer Research and the American Association of Paediatrics and is on the editorial board for several peer-reviewed journals.
