Avi Roy Chowdhury recently presented paper titled "HIERARCHICAL HYBRID SIMULATION MODELING OF BACTERIAL DISEASE INFECTION", (co-authored with Prof. Jayendran Venkateswaran, and Om Damani), at the 12th Simulation Workshop 2025, held at the Mercure Rougemont Hotel, Exeter, UK, from 31 March to 2 April 2025.
Avi Roy Chowdhury attended the conference along with Prof. Jayendran Venkateswaran (member in panel discussion).
The paper focuses on modeling complex global health systems—specifically, infectious disease dynamics—by balancing detail and abstraction. They presented a hybrid simulation approach that integrates System Dynamics (SD) and Agent-Based Modeling (ABM) to study bacterial infection spread at both the individual (within-host) and community (population-level) levels.
The SD model captures individual-level processes like bacterial growth, immune response, and antibiotic treatment. Meanwhile, the ABM introduces individual variability and interactions, simulating transmission across a population. This integrated framework bridges micro- and macro-level dynamics, providing insights into infection spread and strategies for managing bacterial infections and antibiotic resistance.
