An acoustic engineer and hobby musician, I'm an assistant professor in the
Faculty of Electrical and Computing Engineering at the
University of Campinas (Unicamp).
I received a BSEE and MSEE degrees from the University of São Paulo, Brazil, in 2005 and 2007, respectively. In 2012 I received a PhD from the RWTH Aachen University, Germany, for my work in the area of binaural hearing and spatial audio reproduction.
I currently collaborate with the Interdisciplinary Nucleus of Sound Communication (NICS) and the Laboratory of Signal Processing for Communications (DSPcom). I also coordinate the certificate in sound enginnering at Unicamp.
Engenheiro acústico e músico nas horas vagas, sou professor na
Faculdade de Engenharia Elétrica e de Computação da
Universidade de Campinas (Unicamp).
Me formei engenheiro e mestre pela POLI-USP nos anos de 2005 and 2007, respectivamente. Em 2012 eu concluí o doutorado na RWTH Aachen University, Alemanha, pelo meu trabalho na área de audição biauricular e reprodução de áudio espacial.
Atualmente eu colaboro com o Laboratório de Processamento de Sinais para Comunicações (DSPcom) e o Núcleo Interdisciplinar de Comunicações Sonoras (NICS). Sou também o tutor do certificado em engenharia de som da Unicamp.
In this lab course students will deal with fundamental concepts of electronics. We will do this with a project goal: to build an AMPLIFIER. After familiarizing ourselves with the instruments on the workbench, we will soon get our hands dirty with a very simple type of amplifier, the OpAmp. Then we will "look inside" the black box and analyze the components contained within it, especially the diode and the transistor and how they are used to build different types of circuits, such as voltage regulators, preamps and power amplifiers.
In this lab course students will deal with fundamental concepts of telecommunication. At the end of the course the students will be familiar with classical signals and their properties as well as with linear and time invariant systems. Further on, students will verify the concept of AM and FM modulation and demodulation as well as PCM coding.
In this course we will discuss semiconductor devices. At the end of the course the students will be familiar with diodes and transistors., and should be able to understand and implement circuits with operational amplifiers, circuits for data conversion, as well as sensors and actuators.
In this course we will discuss continuous and discrete signals and linear and time invariant systems. At the end of the course the students will be familiar with Fourier analysis, as well as with Laplace and Z-transforms, and should be able to work with applications such as linear filtering and signal sampling.
This course is aimed at non-engineering students. Through this course they will become familiar with the definition of deterministic signals and their interaction with linear systems invariant over time. Time-frequency intuition should be acquired without the use of advanced mathematics, still allowing students to analyze and solve problems from the point of view of signals and systems theory.
This course is a series of seminars given by professors and researchers in the area of acoustic and sound engineering. At the end of this course students should have a general understanding of the research possibilities in several areas related to the study of sound.
This course is a series of seminars given by professors and researchers in the area of music technology. At the end of this course students should have a general understanding of the research possibilities in several areas related to the study of sound.
At the end of this course students should be able to measure sound pressure level, intensity and power and adequately process these measurements to extract further acoustic parameters, such as acoustic impedance, reverberation time, absorption coefficient and others.
At the end of this course students should be able to design a system of analysis and synthesis of musical signals and properly handle their parameters.
At the end of this course students should be able to explain how electroacoustic devices such as microphones and loudspeakers work based on solid engineering principles.

It is proven that the conventional chalk and blackboard method is not the most efficient teaching strategy. New methodologies such as active learning and peer instruction arise as more efficient schemes. However, this strategies have yet to be adapted to the electrical engineering teaching environment.
