[CV | Research Statement]

<first_name> [at] gta [dot] ufrj [dot] br


I am currently at a Pos-doc position at GTA/UFRJ. Before joining GTA, I got my B.Sc. in Electrical Engineering at the Federal University of Rio de Janeiro (UFRJ) in 2004. I also completed my M.Sc. degree in Computer Science at UFRJ in 2006, where I published work in fields such as computer security, mobile computing and mobility and localization in wireless networks.

During the first half of 2007 I started an internship at EPFL in Switzerland where I worked with information dissemination in delay tolerant networks. In the same year I was awarded a ``Ministry of Education, Brazil - CAPES''/Fulbright fellowship, and began my studies towards a PhD degree at the Department of Computer Engineering at University of California in Santa Cruz, which I completed in 2012.

Research

Mobility Management and Characterization

July 2010 – Present

University of California in Santa Cruz - UCSC

This research focus on understanding human mobility through the development of models that can be applied on the simulations of mobile computer networks.

A Machine Learning Approach to End-to-End Round-Trip Time Estimation

September 2009 – June 2010

University of California in Santa Cruz - UCSC

This research focus on modifying and using a machine learning algorithm to estimate the RTT of a data flow and apply it to TCP’s congestion control.

SCORPION Testbed Development

June 2008 – September 2009

University of California in Santa Cruz - UCSC

The Santa Cruz mObile Radio Platform for Indoor and Outdoor Networks (SCORPION) is a hetero-geneous testbed that enables network researchers to study the behavior of network protocols under a large number of mobility scenarios. Played a lead role in the testbed hardware selection, system bring up, design and implementation of testbed management tools, design and implementation of information dissemination protocols, and running early experiments.

Information Dissemination Schemes on DTNs

January 2007 – April 2007

Switzerland - Ecole Polytechnique Federale de Lausanne - EPFL

In this work we studied the propagation of information on a delay tolerant network (DTN) and how to limit it to avoid unnecessary retransmissions. The work consisted in simulations of DTNs, packet forwarding modeling using a proposed ordinary differential equations (ODEs) framework, solved numerically with MATLAB.

Proposal and implementation of a secure software based wireless network environment called AirStrike

February 2005 – February 2006

COPPE/UFRJ

Proposal and implementation of a secure software-based wireless network environment called AirStrike, for Wi-Fi networks.

Calibration-Free Scheme and Software to Locate Wi-Fi Devices

2004 – January 2006

COPPE/UFRJ

In this work we proposed a calibration-free system for locating wireless local area network devices based on the radio frequency characteristics of such networks.
