Research
Embodied AI, Agentic Systems, and Human-Centered Technology
Memory architectures for embodied agents, with a parallel thread in digital well-being and privacy in social computing
Overview
My research spans embodied AI, agentic memory systems, and human-centered technology—work grounded in over fifteen years of software and systems engineering across defense simulation and cloud computing. I am especially interested in memory architectures for embodied agents, including device-agnostic experience memory that decouples learned knowledge from the hardware it runs on.
A parallel track examines digital well-being, privacy behavior, and social computing: how people navigate disclosure and well-being in digital environments, informed by computational psycholinguistics, large language models, and neuropsychological and sociocultural influences on human-computer interaction.
