Michael O'Neill

Michael O'Neill is an Associate Professor at the University of Connecticut, affiliated with the Department of Molecular and Cell Biology / Genetics and Genomics. His research focuses on epigenetic mechanisms in neurodevelopmental disorders and sex chromosome biology, particularly the role of X-linked imprinted genes in transgenerational effects and meiotic sex chromosome inactivation (MSCI).

• PhD: University of Texas at Austin
• Post-doctoral study: University of Melbourne, Princeton University

Research highlights include:

• Elucidating the X Chromosome Imprinting Hypothesis through Turner Syndrome mouse models
• Discovering the role of Xlr3 in MSCI and its transgenerational consequences
• Investigating epigenetic transmission across generations
• Characterizing retroelement dynamics in speciation and genome evolution

His recent publications emphasize X-linked gene regulation, retrotransposon activity, and transgenerational epigenetic effects across mammals, fish, and oceanic species. Contact: michael.oneill@uconn.edu | Phone: 860-486-6856
