Dr. Ricardo M. Czekster

Computer Scientist
Brazilian, born in Porto Alegre, Rio Grande do Sul, Brazil.

Mini-CV


Ricardo M. Czekster works in the intersection of performance evaluation, complex system modeling and application of formalisms in real life problems such as those arising from peer-to-peer realities, software development (global as well), distributed and concurrent systems. Ricardo began studying Computer Science in 1998, where he was awarded two distinguished visiting researcher invitations, one in Grenoble/France, at LIG (Laboratoire d'Informatique de Grenoble) and another at LFCS (Laboratory for Foundations of Computer Science), at Edinburgh/Scotland. Some interests concerns discrete event simulation and solution of structured markovian systems, focusing in Communicating Markov Processes and Stochastic Automata Networks. Another interest verse on stochastic modeling of complex systems, measurements and Software Performance Engineering, to name a few.

Experiences


Undergraduation and Enterprises

1998-2002

Computer Science Bachelor Degree, PUCRS/Brazil.

2000-2004

Software Engineer for the following companies: IntexNet, GoDigital, Promon*IP, Be Wireless and BlueFile.

Undergraduate Course Dissertation

An interactive system for the visualization and measure extraction in medical images. Advisor: Dra. Isabel Harb Manssour

Acquired experiences

It was an important phase to learn interaction and multidisciplinarity within teams with different backgrounds, testing and implementing products for the Internet. During the undergraduation, the final course dissertation involved studying and learning about medical imaging such as Magnetic Resonance or Computer Tomography.


M.Sc. and Academia

2004-2006

M.Sc. in Computer Science, PUCRS/Brazil, information visualization applied to Bioinformatics (protein folding).

Dissertation Title

SimVIZ - A desktop virtual environment for visualization and analysis of multiple protein simulation trajectories. Advisor: Dr. Osmar Norberto de Souza

Acquired experiences

During the masters I was able to study a different problematic then I was used to work with, tackling Computer Graphics and Bioinformatics. The objective was to combine efforts to create an information rich environment for the simulation of protein trajectories. This period also contributed to refine my writing skills, observing the flow of ideas in papers and also publishing original research work in international conferences.


Doctorate and Research

2006-2010

Doctorate in Computer Science, Performance Evaluation, PUCRS/Brazil.

Thesis Title

Numerical solution of markovian descriptors based on tensor terms restructurings. Advisor: Dr. Paulo Fernandes

Acquired experiences

The PhD helped attacking a difficult problem and devise the best possible solution within time constraints, observing performance and elegance. It is also helping my presentation skills and problem discussions with other research groups, verifying the multiple points of view and gathering arguments to defend my position. The research is focused on model solution of SAN, inspecting the Split Algorithm, a hybrid version of both classic Shuffle and Sparse Algorithms, previously defined in the literature.
