*An External Memory Algorithms Platform *(on going project).
The goal is to provide the basis for a system to "mine" dynamic
weighted graphs with several billion edges. This platform has been built as the
initial infrastructure for the Universal Information Graphs projects which is
being conducted at DyDAnthe new funded DHS center
of excellence at *HGV*,
*Graph-Zoom,* *MGV,* and a *Quasi-Clique Extractor.*Each of these components is described
briefly next.

o *Hierarchical Graph Views.*.
A C/C++ library to compute nested partitions of semi-external graphs. It incorporates a variety of recursive graph
partitioning and Markov clustering methods (in cooperation with Roman Dementiev and Ali E. Qursh ).

o *Graph-Zoom*.
A Unix/Windows prototype to navigate large graphs. It
is based on a hierarchy of spanning trees. It incorporates a rectangular
Fish-Eye view technique to provide focus within context. It uses our own
circular layout of graph hierarchies (in cooperation with J. Korn and M. Kreuseler).

o *MGV*.
Uses semi-external memory algorithms to build hierarchical partitions
of weighted multi-digraphs. These partitions are mapped to the screen.
They provide a virtual geography for the input stream. This virtual geography
is used to guide the exploration of the data set. MGV follows the client-server
paradigm and it is implemented in C and Java 3D. (In
cooperation with J. Korn. *US patent*
6781599), 2001.

o* Quasi**-Clique Extractor*.
Extracts subgraphs with density above certain
pre-specified threshold (quasi-cliques) and uses these subgraphs
as seeds to partition the vertex set(in cooperation

A possible way to describe the current stage of my career is that of an experimental computer scientist with a solid theoretical foundation. During the past two decades I became fascinated by the fundamental questions that have been arising from the exploration of very large data sets, (for us a data set is very large if it does not fit on the available RAM).

A variety of massive data sets exhibit an underlying structure that can be modeled as dynamic weighted multi-digraphs with a collection of edge dependent attributes that are application dependent (Web Queries Co-occurrence, Internet data and Telecommunications traffic are prime examples).

When a multi-digraph does not fit in RAM many of the classical algorithms break down. Operations that we usually take for granted, like graph traversing, get wretched when they are faced with the I/O bottleneck. Even though cluster of PC's or enough Parallel I/O are currently used to alleviate this problem, the truth of the matter is that these are just temporal solutions. Behind the scenes, there are fundamental computational questions that are reminiscent of the challenges faced by early computing pioneers. From my view point, sequential media is outgrowing random access storage at a speed and cost that makes imperative to approach the problem of massive data sets as a massive distributed network computing problem instead of using variations of Von Newman architectures that are handicapped by their inherent bottlenecks. This is an area with great potential if we can built off the shelf cost effective computing platforms for large data analysis research.

My confidence for pursuing this area comes in part as a result of 20 years of experience in developing and implementing techniques to process, navigate, analyze and visualize multi-digraphs, arising from the web and the telecommunications industry. The corresponding data sets sizes range from million to several billion edges (please see our contributions to this area in the publication summary). One of the clear messages we have learned is that RAM and processor investments alone are not able to keep up with the data generation ability of the computing and communication devices that are becoming so common in our daily endeavors.

I have been the recipient of several teaching awards at different levels in the educational system. During my undergraduate studies in Mathematics and Physics, I pursued a specialization in Pedagogy.

Arguably, the fast pace of technological and economical developments is causing an erosion on the
foundation of several scientific disciplines. Our era offers a golden
opportunity for Computer Science, Mathematics, Physics, Engineering, Biology
and the Social Sciences to nurture each other in a positive way. There is the
need to develop programs that are*
driven by a hierarchy of interdisciplinary computational challenges that
students complete during their education*. In the next paragraph, I
describe an example of such an approach.

With funds provided by two educational grants, I founded and directed a Laboratory for Algorithms Design. One of its central objectives was to develop educational software to support some classes in the undergraduate curriculum. Unix tools were developed to enhance some fundamental notions that included Turing Machines, Graph Algorithms, the Symmetric Group, Concurrency control and a host of Local Heuristics. A central project in this regard was a client-server system named "AGE: An Animated Graph Environment". It provided the basis of an interactive system for algorithms teaching and student research. In total 43 applications were based on this system. It is worth to point out that all these applications were developed by students that were using AGE as a supporting tool for their classes. This illustrates a possible direction to provide technological training with a solid theoretical backing.Â I believe that knowledge transfer must be structured conceptually; its delivery fun, amusing and entertaining, and its computational experimentation sound and rigorous.
