As of July/August 2000, I am no longer working for SDSC. I'm leaving
this page here for now for the (old) information and links.
I'm a Research Programmmer/Analyst
("Principal Scientist" or, more accurately,
"Principal Technologist")
in the
Data Intensive Computing Environments
research
group
at
the San Diego
Supercomputer Center. SDSC is a National Science Foundatation-funded
supercomputer center at the
University of
California, San Diego.
My primarily role is as the security technologies specialist for the
DICE group.
I'm
currently working on a number or projects related to
the NPACI/SDSC Public
Key Infrastructure / Grid Security Infrastructure
(Help pages,
Online article), including evaluating Certificate Authority packages,
developing
a GSI-enabled FTPD for HPSS, and
a designing and implementing a new CA system based on OpenSSL.
I also recently
developed software to utilize GSI
in DICE
applications
(GSS paper)
such as the SDSC Storage Resource Broker (
SRB),
and
investigated Java applet
signing/security.
Previously, I
was developing SES/Workbench Discrete Event Simulation models of HPSS
and analysing HPSS performance, and developing security software for
the SRB and for HPSS (the non-DCE HPSS client (HSI)). Before that, I
participated in the SDSC DOCT
project, developing an SDSC Encryption / Authentication system (SEA) for use with the SDSC Storage Resource
Broker and other DOCT systems. I also work with security software in
general, which has included Kerberos as described in the Cray User
Group (CUG) paper: SDSC's Installation and
Development of Kerberos and the Secure Shell . My
October 1996 CUG paper, Kerberos/DCE, the Secure
Shell, and Practical Internet Security describes and compares
these and related systems and discusses how SDSC is using them.
Other past projects have included:
Evaluating
Windows NT
for SDSC; helping with our migration to the NSL UniTree
archival storage system as described in a CUG
paper:
SDSC Enhancements to NSL UniTree; and
develping a
a Web-accessible DataBase to track SDSC Computers.
A current side-project is to attempt to develop a Molecular Science
application similar to SETI@Home, BioSci@Home to utilize idle time on thousands on PCs
across the internet to do significant science.
I've been with SDSC since it started in 1985, and have been involved in many
projects ,
many of which have been described in various
publications .
I was manager/group leader of the Central Systems Software group within the
Systems Software Department
1988 thru 1994 but prefer to spend most of my time on software
development/analysis like I do now.
Before SDSC I was
with the
National Energy Research Supercomputer Center (at the time,
the National Magnetic Fusion Energy Computer Center (NMFECC)) which had been
at the
Lawrence Livermore National Laboratory . Before that I was
with Sperry Univac in the Minneapolis/Saint Paul area. I graduated
(magna cum laude) with a BS degree in Computer Science from the
University of Nebraska at Omaha in 1976.
This and related information is available in a
resume format.
Besides the
art of software development and computer technology,
I enjoy mountain bicycling,
motorcycling, music
(rock, metal, jazz, classical) ,
reading
science fiction/fact and technology, investing,
travel, ocean swimming / bodysurfing / snorkling,
nature/city walks, and time with my family.
I'm married and have two children, boys (young men now), ages 20 and 18.
