Summary: A leading figure in molecular psychiatry describes how an early fascination with DNA shaped a career devoted to uncovering the biological roots of neurodevelopmental conditions such as ADHD. By integrating genetics, neuroscience and clinical psychiatry, her work clarifies how DNA variation and environmental influences shape brain development, behavior and risk for psychiatric disorders.
Using experimental models that range from fruit flies to human induced pluripotent stem cells, combined with modern data science and imaging genetics, her group aims to translate molecular insights into more precise, personalized approaches to diagnosis and treatment. A recent focus on epigenetics — how life experiences change gene activity — points to new opportunities for early detection and prevention.
Key Facts:
- Genetic foundations: Variations in DNA contribute substantially to brain function and behavior, helping to explain susceptibility to neurodevelopmental conditions like ADHD.
- Environmental interaction: Epigenetic mechanisms show how experience and environment can modulate gene expression and influence mental health trajectories.
- Next-generation psychiatry: Combining molecular tools, experimental models and data-driven analytics supports development of individualized treatment strategies and improved nosology for psychiatric disorders.

In a comprehensive Genomic Press interview published today, Professor Barbara Franke recounts her scientific journey from a nature-curious child to one of the most influential researchers in biological psychiatry.
Professor Franke, a molecular psychiatrist at Radboud University, has significantly advanced our understanding of how genetic variation can lead to altered behavior in neurodevelopmental disorders, with a particular emphasis on ADHD.
From HeLa Cells to Human Behavior
Her path took a decisive turn during a laboratory practical in which she isolated DNA from HeLa cells. That experience convinced her that molecular genetics was her vocation, shifting her academic interests from observational studies of primates to the molecular mechanisms of human behavior.
This shift led Professor Franke into psychiatric genetics, where she has tackled controversial and often misunderstood conditions such as ADHD. With more than 500 peer-reviewed publications, she ranks among the top 1% of most-cited scientists worldwide. Her work goes beyond mapping risk genes: it uses integrative methods to connect genetic variation to cellular pathways and brain circuitry that underlie behavior.
“Data science gives us unprecedented insight into biological pathways and cellular substrates of psychiatric disorders,” she says, while underscoring the continued need for experimental validation to confirm computational predictions.
Building Bridges Across Disciplines
Professor Franke has founded and led multiple international consortia, including the International Multicentre persistent ADHD Collaboration (IMpACT) and the ECNP Network ADHD across the lifespan. As a founding member of the Psychiatric Genomics Consortium, she championed large-scale international collaboration as essential for progress in psychiatric genetics.
Her research combines advanced bioinformatics, neuroimaging genetics and experimental systems—from Drosophila models to human stem-cell-derived neurons—to ask how genetic differences translate into functional changes in the brain and behavior. This multi-level strategy aims not only to identify risk variants but also to reveal the underlying mechanisms that could be targeted therapeutically.
A New Vision for Psychiatric Classification
As head of the Medical Neuroscience department at Radboud University Medical Center, she advocates for a new psychiatric nosology grounded in biological evidence. Her recent work in epigenetics examines how environmental exposures interact with inherited predispositions, offering potential biomarkers for risk, treatment response and critical developmental windows for intervention.
Her balanced perspective is reflected in a German proverb she often cites: “Die Suppe wird nicht so heiß gegessen, wie sie gekocht wird” (“The soup is not eaten as hot as it is cooked”), a reminder to weigh enthusiasm with careful evaluation—an attitude she applies both to science and mentorship.
Impact Beyond the Laboratory
Beyond publications and awards, Professor Franke has had a broad influence through mentorship and leadership. Her “jump first, think later” ethos encourages early-career scientists, especially women, to take calculated risks and seize opportunities. She believes such a cultural shift toward bold, collaborative science could accelerate discovery.
Her recent adoption of single-cell resolution techniques to study DNA modifications and transcriptomes may help identify biomarkers of treatment response and pinpoint developmental windows when interventions are most effective. These approaches exemplify how integrating molecular biology, neuroscience and clinical practice can create clearer paths from basic discovery to patient benefit.
As psychiatric disorders continue to affect millions worldwide, her interdisciplinary work offers tangible hope for better diagnosis, prevention and personalized treatment. The remaining challenge is moving these biological insights into routine clinical care—how fast that translation happens will determine their ultimate impact on patient outcomes.

Understanding the biological pathways from genes to altered behaviour in neurodevelopmental conditions like ADHD – paving the way for improved understanding and care in psychiatry by Barbara Franke et al. (Genomic Psychiatry)
Abstract
Understanding the biological pathways from genes to altered behaviour in neurodevelopmental conditions like ADHD – paving the way for improved understanding and care in psychiatry
In this interview, Professor Barbara Franke of Radboud University summarizes a career devoted to connecting genetic variation with biological mechanisms that influence neurodevelopment and behavior. Her work spans large international collaborations, computational genomics, imaging genetics and experimental models, and has driven advances in understanding ADHD and related conditions.
Franke’s leadership in international consortia and her adoption of complementary methods—from population genetics to single-cell epigenomics—reflect a commitment to interdisciplinary, collaborative science. Her research increasingly focuses on how inherited risk and environmental exposures interact, with the aim of developing better diagnostic categories, tailored interventions and preventive strategies for psychiatric disorders.
Guided by a pragmatic outlook and a dedication to mentorship, her research continues to inspire progress at the intersection of genetics, neuroscience and clinical psychiatry, with the long-term goal of translating molecular discoveries into concrete improvements in patient care.
