My major scientific contributions
In 2011 I had the unique opportunity to start work at the Department of Genetics, UMCG, as a pediatrician focusing on translational genetics. I was trained as a pediatrician specializing in inborn errors of metabolism and was head of the Department of Inborn Errors of Metabolism at UMC Utrecht for 12 years. As a clinician working on rare inherited disorders, my major interest has always been how patients can benefit from the new techniques and treatment modalities generated in science labs.
During my medical studies I did rotations at the Department of Genetics, University of California in San Francisco (Prof. C. Epstein) and at the Department of Genetics, Hospital for Sick Children in Toronto (Prof. R. Worton). From 1998-1999, I worked in London as a research fellow at the Department of Child Neurology, Great Ormond Street Hospital and the Institute of Child Health, where I studied neurometabolic disorders. I have worked in this field ever since.

Abnormal Neurological Development - Early Diagnosis and Intervention
I am now co-leader of the ANDDI research programme, which will study early diagnosis and intervention in children with abnormal neurological development in a multidisciplinary setting and cover all aspects, including aetiology, pathogenesis, epigenetics, diagnostic applications, accurate phenotyping (dysmorphology, neuroradiology, orthopedagogy) and intervention (diet, medication, etc.). It is part of the BCN-Brain Institute and of the Graduate School for Medical Sciences, Groningen. More

My international recognition and diffusion
I gained international recognition for my scientific work after publishing a breakthrough paper in the Lancet in 2004, reporting for the first time a successful treatment of an affected human fetus with the amino acid L-serine. This paper was highly appreciated by the scientific community and I was awarded the international Horst-Bickel Award for this work in the same year.
The Lancet paper reflected my continuing quest to improve treatment for children with neurological disorders, and serine deficiency in particular. In subsequent publications, I was able to demonstrate the significance of D-serine in early human neuronal development and reported new analytical tools to detect D-amino acids in biological fluids. Recent projects to apply these novel techniques include the role of D-amino acids in amyotrophic lateral sclerosis (ALS), psychiatric disorders, and type 2 diabetes.
Besides my fascination for amino acids, I was also involved in the discovery of three new disorders (CDG syndrome 1b, 1k and COG 6 deficiency) and the delineation of two other new diseases (serine deficiency and periodic fever/mevalonate kinase deficiency.
The focus of my clinical appointment was not only on improving diagnostics for rare disorders of the central nervous system and unexplained mental retardation, but also to improve the treatment and care for these patients. I have specific expertise on prenatal therapy for inborn errors of metabolism, stem cell transplantation for neurodegenerative disorders, and applications of the ketogenic diet.
My appointment at the Departments of Genetics and Pediatrics in the UMCG allows me to combine my expertise in delineating new disorders with molecular and biochemical research tools (next-generation sequencing and mass spectrometry) to enhance diagnostic strategies, and systematically unravel new disorders and subsequently explore potential treatments.
My ability to inspire younger researchers
In recent years I have supervised the PhD theses of 5 young researchers and was able to inspire others to start their scientific careers in the field of inborn errors of metabolism.
From 2002 to 2012, I was registered as a pediatric specialism trainer for the sub-specialization of Inborn Errors of Metabolism. In the past few years, four pediatricians were trained in this field under my supervision. In addition, I am involved in a training program for pediatricians from Indonesia in inborn errors of metabolism, which has so far trained 5 visiting clinical fellows from Indonesia.
My strategic leadership qualities
I am studying to gain an MBA in Health Care Management. Strategic leadership qualities are an integral part of this course. I started the MBA despite already having gained substantial management and leadership experience. In today’s rapidly changing academic and healthcare environment, I felt that an MBA would strengthen my skills to the level required for a responsible academic and strategic leader.
For 12 years I was the head of the Department of Metabolic Diseases at the UMC Utrecht, managing a group of medical specialists and a research group. During this period I was also president of the Dutch Society for Inborn Errors of Metabolism, which contributed much to my management experience.
