The long-term goal of our research is design and development of digital therapeutics (mobile medical apps and videogames) which integrate non-pharmacological interventions with pharmaceutical drugs. Since mobile apps and videogames have become FDA-approved software as medical device, we aim to develop drug-device combination products targeting a specific chronic disease at both molecular and behavioral levels.

Why do we focus on developing digital therapeutics? Because: (1) they can mitigate limitations of pharmaceutical drugs (adverse effects, non-adherence, drug-resistance, affordability, shortages), (2) mobile app-based treatments can improve sustainability of health care by delivering self-care and promoting prevention of chronic medical conditions, and (3) digital transformation in medicine and health care has been happening.

Please see examples of our research projects and articles on mobile health technologies and digital therapeutics:

Our research has advanced development of neuropeptide-based drug leads for the treatments of epilepsy and pain. This collaborative project with Prof. Steve White and Prof. Cameron Metcalf yielded several galanin-based lead compounds such as NAX 505-5, NAX 409-9 and NAX 810-2 (a candidate for Investigational New Drug (IND) for the treatment of epilepsy). Noteworthy, our galanin-based compounds also exhibit analgesic properties, offering opportunities to develop first-in-class therapies for inflammatory and chronic pain. Please see examples of our research publications related to neuropeptide-based drug discovery and development (in chronological order):
