Distributed Systems
My main area of interest is the general field of distributed systems. Of particular interest to me are Peer-to-Peer (P2P) systems and networks. I have analyzed traffic and query performance in file-sharing P2P networks (Gnutella) and I have designed efficient search mechanisms based on the findings from my analysis. My prior work looked at designing mechanisms for creating efficient and well-connected unstructured topologies.Data Analysis - Algorithms and Database Designs
As a by-product of my analysis of P2P systems, I have recently become interested in the general field of data analysis. Specifically, I am interested in data mining, machine learning, and knowledge extraction. Also, I am very interested in the design of new and novel database and database-like storage and data management systems to facilitate the use of modern data mining and analysis algorithms.Distribtued Software Frameworks
A peripheral area of interest is software architectures for distributed, object/component systems. Specifically interested in software architectures that allow for seamless integration across distributed object/componet technologies. I have written a chapter on designing flexible component systems for the book "Component-Based Software Development".Publications
