Complex dynamics
Periphery and central systems including their various interacting regions produce complex behaviors, which are the foundation of Multisensory Integration consequently forming our perception.
Interactions of photons with materials and biological tissues are complex. For instance, electronic and photonic interactions in crystals are the result of the collective behavior of basic atomic or molecular units. Take brain spectroscopy where light interacts with cortex tissue, which contains vast numbers of neurons. Think of muscle contractions as the product of an immense number of interactions between single motor units giving as a result analog behaviors as photons confined within a cavity at thermal equilibrium.
Our group integrates the many engineering and physics tools to understand complex physical and biological systems. Specifically, the group takes advantage of interdisciplinary expertise in optics, mathematics, photonics, electronics, and biophysics (to name but a few) to extract fundamental principles underlying biological rhythms involved in human perception, motor activity, and brain dynamics, from biological measurements performed in the lab.
