Floris Groenendaal finished Medical School of the Erasmus University Rotterdam in 1984. From 1984 1986 he worked at the Institute of Physiology I (Neurophysiology) of the Erasmus University Rotterdam and defended his PhD thesis: "Perinatal hypoxia and visual functions in infants and children" in January 1988. From 1986 to 1991 he was trained in paediatrics in the Sophia Children’s Hospital in Rotterdam. His fellowship neonatology was spent at the Sophia Children’s Hospital, Rotterdam, and the Wilhelmina Children’s Hospital, Utrecht.

Since April 1993 he is consultant neonatology at the Wilhelmina Children’s Hospital/University Medical Center, Utrecht, The Netherlands. At present he is associate professor of neonatology.

In 1994 he was funded by the Ter Meulen Fund to spend his post-doc period at the Department of Physiology of the University of Pennsylvania, Philadelphia, USA. The main focus of his scientific research is: early detection of neonatal brain injury (including MR techniques) and neuroprotection. Under his guidance hypothermia was introduced as standard therapy for neonates with perinatal asphyxia in the Netherlands in 2008. Meanwhile, in collaboration with the NIDOD laboratory of the UMC Utrecht novel therapeutic  strategies have been developed and tested in animal models.

He has been involved in many PhD studies, and has obtained grants from different sources. Publications cited in PubMed include more than 250 papers.

He is member of many professional societies.
