Universidade de São Paulo (USP). Instituto de Física de São Carlos (IFSC) (Institutional affiliation from the last research proposal) Birthplace: Brazil
B.Sc. in Physics from Pontifícia Universidade Católica do Rio de Janeiro (1991), M.A. in Science from University of California at Berkeley (1994) and Ph.D. in Physics from University of California at Berkeley (1998), working with nonlinear vibrational spectroscopy of interfaces. Held a post-doc position at the University of California at Santa Barbara (1999-2001), where he used ultrafast pump-probe spectrocopy to investigate charge carrier photogeneration in semiconducting polymers. Was appointed Assistant Professor of Physics at Sao Paulo State University (Unesp) at Bauru (2001). In 2003 took the position of Assistant Professor of Physics at the University of Sao Paulo (USP), located in Sao Carlos - SP, Brazil, and became Associate Professor in 2015. Has experience in physical chemistry of interfaces, focusing on using sum-frequency vibrational spectroscopy to investigate the molecular arrangement at interfaces (adsorption of water and oil on minerals, polyelectrolyte thin films, electrochemistry, Langmuir and Langmuir-Blodgett films and self-assembled monolayers). Another research topic includes the use of optical absorption, photoluminescence and time-resolved spectroscopy to investigate charge photogeneration and recombination or energy transfer in conjugated semiconducting polymers.

Chitosan, an abundant natural polymer, has been used in many biological applications such as drug delivery, gene therapy, tissue engineering and antimicrobial systems. Although these applications have grown greatly in recent years, there are several models for the modes of interaction at the molecular level of chitosan with biological membranes. Therefore, interactions between chitosan de…
Optoelectronic devices based on conjugated organic materials are becoming an attractive alternative to their inorganic counterparts due to their low cost and increased versatility, since they combine semiconducting properties with the processability and chemical diversity of polymers and small molecules. Organic solar cells, photodetectors and light-emitting diodes are examples of such de…

Several cellular processes depend on the interaction of the membrane with molecules in the cytoplasm or in the extracellular medium. Therefore, the study of the structure of cell membranes and their interaction with other molecules is fundamental for advancing cell biology. To perform these in vitro studies, membrane mimetic models are frequently used, such as lipid vesicles, solid-suppor…
The increase in global energy consumption and its impacts on the environment point to the need of developing and using new energy sources that are clean and renewable. In this sense, photovoltaic solar energy has emerged as a promising source, and organic photovoltaic devices stand as a concrete alternative, as they have already shown (in the laboratory) efficiencies of around 18%, combin…
This proposal addresses the study of interfaces in electronic devices based on conjugated polymers (CPs). We will use Sum-Frequency Generation (SFG) vibrational spectroscopy to investigate dielectric/semiconductor interfaces in organic field-effect transistors (OFETs), and semiconductor/metal interfaces in organic photovoltaic cells (OPVs). In OFETs, the SiO2 dielectric will be modified w…

Organic solar cells (OSCs) stand out among emerging photovoltaic technologies due to their flexibility, low weight, and tunable optical properties. However, their widespread adoption is hindered by limited stability under real-world environmental stressors such as humidity, oxygen, temperature fluctuations, and prolonged light exposure. This project focuses on unraveling the key degradati…
Electronic devices based on organic semiconducting materials, such as transistors, have attracted much research interest due to their potential for unique applications in the vast field of large area and flexible electronics, including wearable electronics, personal bio-medical devices and distributed sensors. The operation of organic eld-eect transistors (OFETs) depends on the modulation…
