HIV
Perinatal HIV & CD8+ T-cell exhaustion
Agent-based prediction of how partially-functional exhausted CD8+ T cells contribute to short-term viral suppression in children with perinatal HIV. Calibrated to Indiana School of Medicine pediatric immune activation data.

TB
Mtb host-pathogen interactions & granuloma timing
Cellular ABM comparing Mtb infection dynamics in latently infected vs Mtb-naive individuals — capturing macrophage phagocytosis, granuloma formation, and immune activation over time. In collaboration with the Schlesinger lab at Texas Biomed.

Systems biology of TB-HIV coinfection
Quantifying synergistic pathogen expansion during Mtb-HIV coinfection using multi-scale mechanistic models.

- Coinfection dynamics
PBPK
TB drug distribution: oral vs inhaled
Repurposed a physiologically-based pharmacokinetic model in MATLAB to explore how delivery route alters bacterial burden inside the lung granuloma.
