Philip Michielsen

Philip Michielsen is a Researcher in the Department of Psychiatry at Erasmus University Medical Center in Rotterdam, Netherlands. His work focuses on adolescent and adult psychiatric disorders, with particular emphasis on antisocial behavior, self-harm, and related clinical phenomena.

Dr. Michielsen's research interests span several key areas in psychiatric science:

• Antisocial behavior in adolescents and adults
• Self-harm and dual-harm behaviors (combining self-harm with violence toward others)
• Callous-unemotional traits and their relationship with anxiety
• Parental influences on adolescent behavior, particularly hostility
• Neurobiological markers for suicidal behavior
• Latent profile analysis of behavioral disorders

His research employs sophisticated methodologies including meta-analysis, latent profile analysis, and examination of clinical factors in both community and psychiatric hospital settings. Much of his work focuses on high-risk adolescent populations and those with compulsory psychiatric admissions.

Dr. Michielsen's publication record shows a consistent focus on understanding the complex interplay between different forms of harmful behaviors, particularly the co-occurrence of self-harm and violence toward others ("dual harm"). His recent work includes a systematic review examining the dexamethasone suppression test as a potential biomarker for suicidal behavior, demonstrating his interest in biological correlates of psychiatric conditions.

His collaborative network includes researchers from multiple Dutch institutions, with frequent co-authorship with W.J.G. Hoogendijk, S.J. Roza, and P. Spaan, suggesting established research partnerships within the Erasmus MC psychiatry department.
