All Foraging Behavior Ecological Stoichiometry Infectious Disease Modelling

Sub projects:

Behaviorally structured consumer-resource PDE-ODE systems.
Trait evolution under predation risk and food availability.
Bifurcation and tipping analysis driven by behavioral change.
Noise induced shifts in behaviorally driven dynamics under Gaussian and Levy noise.

These models provide a link between individual level decision making and emergent community level behaviour, with applications to personality dependent predator-Prey systems and movement between risky and safe patches.

Sub projects:

Stoichiometric producer grazer models and comparison of Monod and Droop formulations.
Optimal foraging strategies under nutrient limitation and enrichment.
Stochastic stoichiometric dynamics under environmental variability.
Methane induced transitions in aquatic ecosystems and media driven responses.

This theme combines stoichiometric theory with mechanistic foraging rules to understand how changing nutrient regimes, pollution, and greenhouse gas emissions alter consumer-resource interactions and ecosystem resilience.

Sub projects:

Hybrid mechanistic and statistical model for climate sensitive norovirus in the United States.
Age structured HIV dynamics with PrEP intervention and treatment optimisation.
Diphtheria outbreak reconstruction in Rohingya refugee camps and parameter estimation.
Within host virus diffusion models with latent stages and global stability analysis.

The goal is to connect mathematical structure with public health interpretation, using dynamical systems tools to study threshold conditions, control strategies, and long term behaviour of infectious diseases.
