Introduction
I work on embedded systems and sensor technologies to detect, localize, track, and identify people in smart environments, with a special interest in privacy preservation.
My research interests are human sensing, data interpretation, and system development. I develop technologies that provide assistive services in home and office environments under realistic assumptions, with focus on applications and implementations. One of my primary concerns is preserving a certain level of privacy, by enabling the use of cameras that extract features but cannot take pictures. I consider the problems of detecting people, uniquely identifying them and making inferences from their interactions with the surroundings. For this, I have developed a wireless network of custom camera-nodes that is able to locate moving people in real time with minimal calibration or set-up. This infrastructure has already been used in real homes to infer activities by reasoning about people's locations in relation to known objects in a scene. Lately I have been focusing on problems that arise in multiple-person environments, such as the separation of an unlabeled data trace containing different people into single-person traces.

About me
I was born in Rio de Janeiro, Brazil, in 1980, where I was raised. In 1999 I moved to the United States to pursue my Bachelors degree in Electrical Engineering at Johns Hopkins University with second major in Mathematics. From 2003 to 2005 I worked at the Sensory Communication and Microsystems Laboratory at JHU, where I did my Masters work interfacing address-event cameras and acoustic localization devices to wireless nodes, under the guidance of Andreas Andreou. In 2005, I joined the Embedded Networks and Applications Lab (ENALAB) at Yale University, where I am now a Ph.D. candidate. My advisor is Andreas Savvides.
