CLAUDIO ESPERANÇA

Hi. I am Claudio, and this is my personal page. I've been postponing writing
this for a long time, but no more!


SHORT BIOGRAPHY

I am an Electronic Engineer, graduated at Federal University of Rio de Janeiro
(UFRJ) in 1980. I worked for several companies in Rio de Janeiro, including UFRJ
itself (at NCE), Dataprev, Datapoint, Medidata and Amplus (a now defunct network
company). In 1990 I got a MSc degree in Systems Engineering at UFRJ, more
specifically, at the Program of Systems Engineering and Computing (PESC), one of
the graduate programs in COPPE. My MSc advisor was Dr Ronaldo Cesar Marinho
Persiano (where are you Marinho?). Later, in 1995, I earned a PhD degree in
Computer Science at University of Maryland, advised by Dr. Hanan Samet. I have
been at UFRJ since 1989, first employed as an Engineer and later as a Professor
at PESC, where I pursue my academic interests. These include all things related
to Computer Graphics, such as rendering, animation, computational geometry,
spatial databases, visualization and more. In 2021 I also joined UFRJ's Graduate
Program in Design (PPGD) as a professor.


CONTACT

I can be reached most easily by email at claudio.esperanca@gmail.com (personal)

COURSES TAUGHT AT UFRJ

I use Moodle as an e-learning platform for my courses. The links below will take
you to a copy of the course material hosted at cesperanca.org. You must use a
guest login to access the contents. Most of the material is in Portuguese.

 1. Computer Graphics (COS751)
 2. Data Structures (COS231)
 3. Algorithms and programming (COS110)
 4. Computational Geometry


STUDENTS

I am currently advising the following graduate students (in no particular order)

 1. Renato Campos Mauro. Theme: Techniques for efficient big data web
    visualization.
 2. José Augusto Sapienza Ramos. Theme: Sector lists.
 3. Lucas Barcellos Oliveira. Theme: Progressive web visualization.
