The research interest of the laboratory is focus to determine the relation between chemical structure, chemical dynamics and biological function in hemeproteins. These include oxygen and ligand transport proteins like human hemoglobin and myoglobin and the unique hemoglobin I from Lucina pectinata, as well as electron transfer proteins such as cytochrome c oxidade. Using "site directed mutagenesis" we tailor the structure of this hemeproteins. Then, its chemical structure is then studied by Fourier Transform infrared, resonance Raman, vibrational analysis, and NMR spectroscopies. This is followed by kinetic studies, using time-resolved (pump and probe) infrared and resonance Raman techniques, of the reaction between these hemoproteins and ligands (for example, O2, CO, NO, and H2S).
Finally, ultrafast chemical dynamics of these species are determined in the picoseconds and femtosecond using time-resolved (pump and probe) transient spectroscopy.

Nuestra investigación gira alrededor de estudiar las propiedades químicas y físicas de sistemas en la fase condensada utilizando simulaciones en computadoras. Algunos de los sistemas que estudiamos son agregados atómicos y moleculares, fluidos confinados en nanoestructura, capas finas poliméricas y surfactantes pulmonares.
