Research

collaboration overview

I’m mostly involved with the computer networks research group, but I also do some research in the intersection of machine learning with big data. For each research problem, I try to establish a collaboration (often multidisciplinary, at national and international level) to ensure that the work is analyzed from different perspectives. Another motivation is to put students doing research under my supervision in contact with recognized researchers on the topic, to open up future opportunities (in Brazil and abroad).

some active pet projects

Mapping occurrences of Aedes Aegypti by analyzing mosquito wing beat frequency (with Mariana Mendoza). Our goal is devising a smartphone app that can analyze mosquito sounds and generate a live map of their occurrence.

Community networks (with Jon Crowcroft and Fernando Ramos). Various people in remote villages in the Amazon region lack affordable access and therefore are disconnected from the Internet.  Our goal here is to help bridge the digital divide with the proposal of low end devices for networking in the hostile environment posed by the Brazilian Amazon.

Learning Individual Profiles behind Shared Accounts (with Renata Galante). Various recommendation systems rely on users’ account history to predict which other items one could also be interested in. In practice, multiple individuals may share a single account, which may lead to imprecise item suggestions for the person currently in. We are working on a mechanism for tracking individual profiles behind shared accounts, to help truly personalize item suggestions.

Virtualization of network switches written in P4 (with José Azambuja). Our goal is devising a mechanism for enabling hard virtualization of network switches written using the P4 language.
