About | James Gregory Walsh

Welcome. I’m James Gregory Walsh—Greg, professionally—leveraging a unique background in clinical psychology and data analysis to address complex challenges in behavioral assessment, crisis response, and investigative strategy.

My foundational experience includes over three years as a mental health specialist at McLean Hospital, within the McLean-Franciscan psychiatric unit affiliated with Harvard Medical School. In that demanding role, I conducted clinical assessments, contributed to critical risk evaluations, and collaborated within interdisciplinary teams in acute psychiatric settings. This work honed not just empathy and resilience, but also the ability to make structured, high-stakes decisions under pressure—skills directly applicable to federal and state law enforcement challenges.

Academically, I possess undergraduate and graduate-level training in applied psychology, complemented by robust statistical training. I am proficient in applying data analysis tools like SPSS, R, and Excel to translate complex data into actionable insights, particularly for behavioral risk management, investigative planning, and ensuring civic accountability.

My goal is to bridge the gap between psychological science and practical application in high-stakes environments. I am passionate about using data to inform better decision-making, enhance public safety, and promote accountability. Explore my projects and experience to learn more, or Download My Résumé.
