Personal Page – Professor

He holds a Bachelor's degree in Physics from the Federal University of São Carlos (1985), a Master's degree in Applied Physics from the São Carlos Institute of Physics - University of São Paulo (1988), and a Doctorate in Sciences from Université Paris XI (Paris-Sud) (1992). Currently, he is an associate professor, MS-5, level A3, at the São Carlos Institute of Physics, University of São Paulo. He has experience in physics, with an emphasis on the structure of crystalline and amorphous solids and on the development of materials for sensing toxic gases. In the study of solid structure, he has worked primarily on the following research topics: characterization of the local and electronic structures of Ceramic Materials, Metallic Semiconducting Oxides, Glass, and Nanostructured Oxides, using X-ray Absorption Spectroscopy (EXAFS/XANES), X-ray Diffraction, and X-ray Excited Photoelectron Spectroscopy (XPS). In the development of toxic gas sensor materials, the focus has primarily been on improving their properties, particularly selectivity and operating temperature, with an emphasis on gases such as ozone, ammonia, and hydrogen. This includes the development of gas-sensing materials based on composites or heterostructures of semiconductor metal oxides, graphene, and 2D structural materials such as SnS2.
