Research

In our lab we study a variety of dynamical, biological problems, at very different scales of biological organization: cells, tissues, organisms, and populations. The common ground unifying the different problems we work on is our interest on: a) the mechanisms underlying the dynamic behavior of the studied systems, and b) the emergence of collective behaviors as one moves from a finer to a coarser scale of description. In our investigations we make use of several theoretical and experimental techniques. Among others: mathematical modeling with ode’s and pde's, non-linear dynamics, bifurcation theory, stochastic dynamics, Monte Carlo simulations, cell biology, microfluidics, phase contrast and fluorescence microscopy, image analysis, etc.

Our current projects include:

  • Experimental study of the regulatory mechanisms and dynamic behavior of the tna operon of E. coli (David I. Orozco-Gómez).
  • Experimental and theoretical study of T. cruzi motility and infectivity (Jorge Adrián Arias-del-Angel).
  • Synchronization of the segmentation clock in vertebrate embryo presomitic cells and somitogenesis (Jesús Pantoja-Hernández).
  • Ecology dynamics of a set of interacting bacterial strains isolated from Cuatro Ciénegas, Mexico (Óscar A. Gallardo-Navarro).
  • Synchronization of the circadian clock and the starvation response gene regulatory networks (José G. Guerrero Morín)
  • Calcium dynamics in smooth muscle cells (Laura Sánchez Gómez).
  • Experimental study of the regulatory mechanisms and dynamic behavior of the trp operon of E. coli (Daniela Nevarez Torres).
  • Experimental and theoretical study of calcium dynamics in blood-vessel epithelial cells in response to mechanical stimuli (Ubaldo Espíndola Arias)
