David Crowley

David Crowley, Ph.D., is a Professor of Biology at Assumption University's D’Amour College of Liberal Arts and Sciences. He holds dual leadership roles as Director of ASPIRE and Associate Director of the Center for Purpose and Vocation. His academic credentials include a B.A. in Biology (Cum Laude with Honors) from College of the Holy Cross (1993), a Ph.D. in Biological Sciences from Stanford University (1999), and an M.A. in Pastoral Ministry from Anna Maria College (2013).

Professor Crowley's research focuses on molecular stress responses across biological systems. Key interests include:

• DNA repair mechanisms in extremophiles (especially halophilic archaea)
• Transcription-coupled repair of UV damage
• Oxidative stress neuroprotection (OXR1 gene function)
• Genomic adaptations in Permian halite microorganisms
• Bacterial mutagenesis and repair pathways

His recent work (2020-2023) explores neurodegeneration prevention through oxidative stress control and extremophile genomics, while earlier publications established foundations in nucleotide excision repair and bacterial stress responses.

He mentors undergraduate researchers extensively, with nine identified student collaborators co-authoring publications. Current institutional roles involve directing ASPIRE (academic support/research initiative) and co-leading vocation-focused programming. No grants or awards are documented in available materials.
