I am currently on sabbatical with the Advanced Internet Research Group (AIR) at the University of Amsterdam (UvA). I will be returning to LBNL in August of 2003.

I started designing and implementing high-speed parallel storage systems, but I soon found that I could easily build a system that would break most high-speed networks. Click here for a brief overview of one of the systems that I helped develop, or if you want more info you can check out my Thesis. Having found that it was so easy to break a network I quickly moved into the realm of building networks that would stand up to the onslaught of data. A few of the early projects that I worked on were BAGnet, MAGIC and NTON to name a few. I've moved on now into the area of exploring TCP, particularly in the context of Large Scale Networks (LSN). Click here to see why I think this is such a big problem. As of late I've been working with the web100 people on a new project called net100 that applies some of the techniques that can help improve performance over LSNs to real world applications, you can see some of my progress here.

Over the last couple of years at LBNL I have developed several web based interfaces to work with various other projects here at LBNL. Some of the more notable are; an interface to the ISS, and an interface to a workstation based video camera. I am also in charge of developing and maintaining our groups ATM/Gigabit/FDDI/etc. networks.

Some of my research and development interests are in the areas of:

• The use of "off the shelf" components to build a high speed parallel distributed data server;
  
• High speed network based distributed applications for scientific imaging and the use of video for dynamic object analysis and laboratory control;
  
• Acquisition, storage; processing, analysis, and display of video based scientific image data;
  
• Distributed computer graphics and image processing systems, high speed storage systems;
  
• Ray-tracing, stereoscopic images, volume rendering, and other models of representing data;
  
• Distributed systems in support of supercomputing;
  
• Algorithms for the graphical display (visualization) of scientific information;
  
• Chaos Theory as it relates to fractals, not only the images but as applied to both music, and compression;
  
• Neural Networks. I like to experiment with different back-propagation algorithms, different models of the Hopfield Net, and variants on neural nets such as simulated annealing;
  
• Networking in all its forms. From the design of different models (peer-to-peer, distributed model, client-server, one-to-many (multicast)) to the low layer implementation of IP over ATM.
  
• Security. For the last couple of years I have been active here at LBNL in the area of security. How to monitor attacks, how to counter attacks, tracking, etc. I've also been researching key encryption and Certification Authorities.

Previous Positions

Computer Science Lab Manager: SFSU 1990-1992

Laboratory Manager for the Computer Science Dept.

Managed the University's Computer Science Laboratory. My responsibilities included helping design and implement the network infrastructure for the computer science department. I also was responsible for maintaining all of the labs computers and ensuring that they were available for use at all times. This involved managing a small team of sysadmins for the various types of machines (NeXT, Sun, HP, VAX, etc), and putting together staffing for the different computer labs.

Education

MS in Computer Science from San Francisco State University 1995

BA in Sociology from San Francisco State University 1990
