In 1991 he obtained a PhD in Cell Biology at the medical faculty of the University of Amsterdam studying the genetic basis of inherited peroxisomal storage disorders. He continued as of 1990 as a post-doctoral fellow at Nijmegen University, obtained a National Science Council fellow-ship for a short-term stay at Rockefeller University New York, and went in 1994 to work for Unilever Research and Development.
From 1994 to 1999, he fulfilled at Unilever several scientific and managerial positions from project to program manager. In addition he received training in project and program management as well as general management and finance from the London Business School, the Lausanne Business School and INSEAD, France.
In 1999, Stanley Brul was appointed professor of Industrial Microbiology on an endowed chair at the Swammerdam Institute for Life Sciences of the University of Amsterdam while remaining until 2002 at Unilever Research & Development as senior scientist novel (micro)biological technologies.
As of 2002, the University appointed him as full professor of Molecular Biology & Microbial Food Safety (MBMFS) at the Swammerdam Institute for Life Sciences.
From 2003 till now he acted together with a counterpart at the medical faculty of the University as coordinator of the master program in Biochemistry and Metabolic Disease. Concomitantly he consulted for 2 days a week at Unilever on the deployment of novel ‘omics’ based approached in food microbiology. Since the end of 2007, Stanley Brul has been fully employed by the University and was simultaneously appointed director of the bachelor program in Biomedical Sciences whilst remaining master coordinator of Biochemistry & Metabolic Disease.
At the University he obtained further education qualifications. Brul’s group studies microbial stress response mechanisms of relevance to prevention and cure of infections. The group focusses on bacterial spore formers in close collaboration with the proteomics group of prof. de Koster and the Centre for Advanced Microscopy of the University (Dr. Manders). External collaborators include prof. Mike Peck at the IFR (Norwich, UK), prof. Frederic Carlin (INRA, Université d’Avignon, France) and prof. Peter Setlow (University of Connecticut, USA). In addition the group has a growing interest in the occurrence and development of antibiotic resistance in the food chain as exemplified by the recent appointment of prof. Ter Kuile on a novel endowed chair embedded within the group. Dr. ter Kuile is senior scientist at the Dutch Food Safety Authority (NVWA) and member of a European expert panel of the European Food Safety Authority. The NVWA funds two PhD students on this topic at the group. Stanley Brul teaches courses in molecular microbiology, biochemistry, nutrition and human molecular physiology. His review with Peter Coote on Preservative agents and their mode of action from 1999 has been cited over 800 times. Overall he has over 5850 citations in Google scholar and an H-index of 41. The groups of Brul, de Koster and Manders publish in a collaborative effort yearly around 15 papers and generally 2-3 PhD students finish their studies.
