He has been working in the field of biophysics since 1977 starting with the first applications of XANES (x-ray absorption near edge structure), named by him, using synchrotron radiation to the determination of the local structure of active sites of metalloproteins in solution.

He has contributed to several topics:

XANES of metal ions in biological membranes

XANES of calcium binding proteins: calmodulin, S100, troponin-C, parvalbumin

Active site structure of hemoglobin, myoglobin,

Ligand binding angle in emoproteins in solution and crystal

Polarized X-ray absorption of proteins

He has introduced new physical experimental methods and concepts:

XEOL: x-ray emission optical luminescence;

XANES: x-ray absorption near edge structure, due to multiple scattering resonances for detecting high order correlation function of the local structure in complex systems:

SUPERSTRIPES: heterostructures at atomic limit where the quantum mechansm for evading temperature decoherence effects appears by tuning the chemecal potential.


Moreover he has been working in:

Liquid helium film

Photon-surface plasmon wave transformation

Photoemission spectroscopy of complex disordered systems since 1975

Synchrotron radiation research since 1972

Core excitons in synchrotron radiation absorption spectroscopy

Shape resonances in synchrotron radiation absorption spectroscopy

Multiple scattering resonances in XANES of complex systems

Ions in solution.


Surfaces and interfaces

Correlated electronic systems

Valence fluctuation systems
