In this Genomic Press Interview, Deanna M. Kaplan, PhD, emerges as a pioneering clinical psychologist reshaping how we understand human experience through innovative ambulatory assessment technologies at Emory University School of Medicine, where she serves as Assistant Professor, Director of Health Technologies for Emory's Spiritual Health Program, and Director of the Human Experiences and Ambulatory Technologies (HEAT) Lab. Dr. Kaplan has distinguished herself through groundbreaking methodological contributions, including the development of Fabla. This smartphone application revolutionizes clinical research by securely capturing voice narratives and speech biomarkers in participants' natural environments, currently utilized across multiple research domains from psychedelic-assisted therapies to physician burnout studies. Her interdisciplinary expertise spans ecological momentary assessment, the Electronically Activated Recorder (EAR), and various ambulatory monitoring techniques, with over 50 peer-reviewed publications examining the intersection of daily life experiences, clinical interventions, and digital health technologies. With significant funding from the National Institutes of Health and other organizations, Dr. Kaplan's forward-thinking research addresses critical questions at the nexus of behavioral science and artificial intelligence, emphasizing ethical approaches to voice data analysis that preserve the richness of human subjectivity while leveraging technological advances to enhance understanding of psychological change mechanisms in real-world contexts. A graduate of the University of Arizona (PhD, 2020) with postdoctoral training at Brown University, Dr. Kaplan's innovative research program explores both the transformative potential and ethical challenges of emerging technologies in clinical science, investigating how relationally-focused ambulatory assessment methods can advance personalized interventions while maintaining the essential human elements of care.
