The overarching scientific objective of my research program is to enable systematic development and assessment of next-generation autonomous medical and healthcare systems, by (i) elucidating sophisticated mechanisms underlying physiological systems and processes bearing clinical relevance via the development and analysis of medical digital twins (M-DTs: trustworthy mathematical models that can replicate the physiological process behaviors) and (ii) leveraging M-DTs and novel insights garnered from M-DTs in the disciplined development and assessment of innovative autonomous medical diagnostic and therapeutic systems.

My research program is currently dedicated to 4 thrust areas, namely: (i) physiological signals and systems analysis, (ii) psycho-physiological monitoring, (iii) physiological monitoring and closed-loop control (PM-CLC), and (iv) cardiovascular health and disease monitoring.  In the physiological signals and systems analysis area, my research aims at advancing knowledge on the physical mechanisms and implications pertaining to physiological signals and systems, and transforming such knowledge into innovative wearable-based healthcare systems.  In the psycho-physiological monitoring area, my research aims at developing transformative monitoring paradigms for physiological and mental health superior to the state-of-the-art in accuracy and convenience.  In the PM-CLC area, my research aims at developing M-DTs suited to the development and assessment of PM-CLC systems, M-DT-based virtual patient generation methodology suited to the trustworthy assessment of medical autonomy, M-DT-based PM-CLC algorithms, and wearable bio-robotics.  In the cardiovascular health and disease monitoring area, my research aims at developing a low-cost, non-invasive, and personalized paradigm for cardiovascular health assessment as well as cardiovascular disease detection and diagnosis via physics-inspired and machine learning-enabled approaches.
