Background
Born
in Belo Horizonte,
state of Minas Gerais
Electronic
Engineer by the Minas Gerais Federal University (UFMG,
1990).
MSc.
in Electronic Engineering by the Escola
Politécnica of the University of Sao Paulo (USP,1997).
PhD.
in Electronic Systems/EE at the University of Sao Paulo/Polytechnic School
(2005).
Musician
(flutist). Studied basic music theory with conductor Rogério Moreira
Campos, at the Viçosa Federal University (UFV),
and Transversal Flute with Karen Louis Currie de Carvalho (Viçosa,
MG, Brazil).
Position
Associate
Researcher at LSI, Laboratório
de Sistemas Integráveis EP-USP,
and manager of the Media Engineering Center since 1997, working with R&D
projects on multimedia technologies, 3D audio, MPEG systems/technologies,
and Digital TV. The Media
Engineering Center has been researching and developing electronic multimedia
platforms (set-top boxes) for communication networks access for terrestrial
digital TV (DTV) and CATV since 1998, as well as interactive multimedia
services prototypes (hardware/software), having introduced novel wide-band
multimedia service prototypes in the country over high speed networks (aplications
prototypes for Internet2 such as audio and video
on demand). Currently working on the development of digital set-top
boxes projects for the SBTVD (Brazilian iniative for a Digital TV System)
and technologies for spatial audio (2D/3D surround).
Interest Fields
Audio
engineering, music technology, spatial audio (2D/3D), MPEG coding systems
and technologies, advanced architectures for multimedia systems, interactive
media, musical production and multimedia signal processing.
Participation in Events
Actively
attendance/participation in several national and international meetings,
such as AES, SIGGRAPH, SIBGRAPI, SBC (SBCM),
SET, ICAD, SPIE e iGRID. In 1998 lectured in the scientific meeting Advanced
Study Institute on Signal Processing for Multimedia supported by NATO in
Italy. In 2001 was invited lecturer in the Artspages International Conference,
Oslo, Norway. In 2002 lectured on technologies for digital TV in the Brazilian
Television Engineering Society anual meeting - SET
(Forum SETBusiness. “ISDB-T Tutorial”). In 2003 lectured on audio
quality in perceptual codecs at the VII
National AES Brasil Convention (“Qualidade em CODECs Perceptuais”)
and presented a tutorial on multimedia coding with open standards at SET
2003 (“Codificação Multimídia – Tecnologias e
Projetos”. Rio de Janeiro/2003). In 2005 presented works at SET 2005
convention and SMCT meeting
(Seminars of Music, Science and Technology) on the development of MPEG-4
AAC CODECS and system architectures for spatial sound production. Member
of the technical commeetee of the AES Brasil conference in 2003, 2004 and
2005. Member of NUCOM council (interest group in computer music of the
Brazilian Computer Society).
Master
Regarding
musical production and computer music, interests focus on the representation
and modeling of expressivity and performance naturalism. His MSc. work
addressed the use of wavelets in the analysis of musical gestures in timbres
of traditional acoustic instruments. Expressive musical passages (phrases)
from flute and violine were analyzed with this technique in order to study
its ability to extract patterns representing expressivity and naturalism,
qualities embedded in human performances. MSc
work Abstract.
Doctorate
His
PhD work addresses the study of technologies for spatial audio (3D), trends
and applications, with special focus on implementation of solutions for
3D audio in immersive virtual reality and the proposition of integrable
and open architectures for the production, transmission and consume of
spatial audio / sound. PhD work Abstract. The
R&D project AUDIENCE
(LSI/2004/2005) addresses the building of systems for 2D/3D audio for the
Caverna
Digital (Digital CAVE) in the Polytechnic School of the Univ. of Sao
Paulo, and the development of experimental systems for surround/immersive
audio, using techniques such as Ambisonics and Wave Field Synthesis (novel
prototypes for inovative technologies for coding/reproduction of 3D audio).
