Astrid D. Haase

Astrid D. Haase, M.D., Ph.D., serves as a Senior Investigator with tenure at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), National Institutes of Health (NIH), where she leads the RNA Biology Section within the Laboratory of Cell & Molecular Biology. Her research focuses on PIWI-interacting RNAs (piRNAs) and their critical role in safeguarding genomic integrity through transposon silencing in germ cells, with implications for fertility and disease prevention.

Her academic training includes:

• M.D. from the University of Vienna, Austria, with research at the Institute of Molecular Pathology (2000-2002)
• Ph.D. from the University of Basel, Switzerland, at the Friedrich Miescher Institute for Biomedical Research (2002-2007)

Dr. Haase's research integrates genetics, genomics, and biochemistry to unravel molecular mechanisms of RNA-guided genome protection. Her work demonstrates how piRNA pathways defend against mobile genetic elements, ensuring germ cell health and fertility. Disruption of these mechanisms links to infertility, inflammation, and cancer, driving her exploration of therapeutic applications for genomic instability disorders. Current projects examine piRNA biogenesis, transposon control, and evolutionary adaptations across species.

Analysis of her 15 most recent publications (2019-2025) reveals consistent focus on piRNA molecular mechanisms, transposon silencing, and genomic defense strategies. Key contributions include elucidating piRNA precursor formation, 3'-end establishment, and cellular abundance effects on silencing efficiency. Her work spans model organisms from Drosophila to mammals, with emerging applications in biotechnology and fertility treatments.

No specific scientific awards are documented in the provided materials.

As Section Chief, Dr. Haase mentors postdoctoral fellows and laboratory staff within the NIH intramural program. Her research receives stable institutional funding, enabling long-term investigations into RNA biology. Collaborative projects with international researchers, evident in co-authored publications, advance understanding of conserved genome defense mechanisms across diverse species.

The RNA Biology Section employs interdisciplinary approaches to investigate how small non-coding RNAs maintain genomic stability. Her laboratory combines cutting-edge genomics, biochemistry, and genetic techniques to dissect piRNA pathway components, with recent work exploring evolutionary dynamics in systems ranging from cichlid fishes to mammalian transposons. This research environment fosters innovation in understanding fundamental biological processes with translational potential.
