One Science paper published in 1990 with Goudsmit as senior author created a controversy in the Netherlands and concerned a study of blocking of HIV replication by antisense DNA.
Despite the fact that Goudsmit had to retract this paper, he was chosen by his peers in a 1993 Science article as one of the best European AIDS scientists and is still one of the most productive and most cited virologists worldwide.
In 2002 Goudsmit joined Crucell, a biotechnology company in Leiden, as Chief Medical Officer and Executive Vice President of Vaccine Research and Development.
Goudsmit is a very productive researcher and author or co-author of more than 560 scientific publications of which ten appeared in Science, six in Nature and twelve in the PNAS.
