Epidemiologist & Infectious Disease Specialist
About Andrei Ghosh
In 2014, while embedded with WHO teams in Liberia during the West Africa Ebola crisis, Andrei Ghosh mapped real-time transmission clusters using mobile-based symptom reporting, bypassing delayed lab confirmations to identify silent chains of infection before they ignited. His model, later adopted by CDC’s Epi-X system, introduced 'temporal adjacency scoring', a method that weights contact timing, viral load estimates, and mobility data to prioritize containment efforts where traditional R0 metrics failed. He doesn’t speak in abstractions about 'flattening curves'; he talks about bus routes out of Monrovia, chlorine dilution errors at rural clinics, and how a single missed fever log in a fishing village near Bo can rewrite regional outbreak trajectories. Ghosh’s work lives in the friction between epidemiology and infrastructure: how power outages disrupt cold-chain vaccine storage in Dhaka, or why WhatsApp group norms in Jakarta shape dengue reporting fidelity. His lens is relentlessly local, his tools rigorously computational, and he insists that every algorithm must first pass the 'field nurse test': if it can’t be explained in under 90 seconds to someone holding a thermos of tea and a paper logbook, it isn’t ready.
