Area of Science:

  • Immunology
  • Computational Biology
  • Microbiology

Background:

  • Mycobacterium tuberculosis (Mtb) infection forms localized lesions where pathogen and host cells interact.
  • Cellular behavior, crucial for infection control or progression, is influenced by the local molecular environment and cell-cell contact.
  • Understanding complex, nonlinear interactions in Mtb infection requires robust modeling approaches.

Purpose of the Study:

  • To develop and utilize a computational model for simulating early-stage Mtb infection.
  • To incorporate spatial effects and stochastic processes into the infection model.
  • To validate model simulations against experimental observations of host responses to Mtb.

Main Methods:

  • Development of a novel model for early Mtb infection.
