Objectives

I am currently studying the applications of logistic regression, Dynamic AD-trees, and other statistical classifiers to high-
dimensional data mining problems for discriminative and modeling applications. Though I find algorithms and data structures
fascinating, my computing interests extend to the hardware and software systems that enable massive computation and au-
tomated data analysis. My interests also include the technological, economic, and social environments that facilitate and
constrain scientific exploration and problem solving. I prefer collaborative research and development with direct application
to real-world problems. I am project-oriented, persistent, and comfortable in environments where interdisciplinary teams solve
impossible problems on a tight budget in record time.

Western Washington University, Department of Mathematics, September 1996 to June
1997, developed Maple-based two- and three-dimensional tomographic reconstruction soft-
ware for convex polytopes

Mathematics Fellow

Western Washington University, Department of Mathematics' Math Center, September
1994 to June 1997, upper-division mathematics tutor

Deployed Hardware and Software Systems

LR-TRIRLS

May 2005- First source release for my Logistic Regression with Truncated Regularized It-
eratively Re-weighted Least Squares software. Licensed under the GNU General Public Li-
cense (GPL), available at

http://www.autonlab.org

and

AFC Active Learning

September 2004- Active learning software for scheduling roboticized pharmaceutical ex-
periments (see AFC, below). I am responsible for the design, implementation, and main-
tenance of this software. This software has been delivered to the sponsor, and will be
maintained and distributed contingent on future contracts.

Auton Fast Classifiers (AFC)

April 2002- Fast classification software for high-dimensional datasets. I provided new al-
gorithms and eventually took over the entire software system, including the user interface,
learner and and dataset framework, performance evaluation, and documentation. This soft-
ware is still in use by the sponsor, is maintained regularly, and has been widely distributed.

Aethon Elevator Controller

January 2002- Software for managing a single-board computer and serial interface board
connected to an elevator's control system. I developed a protocol and daemons for bidirec-
tional communication between a mobile robot and a passenger elevator. Aethon's current
elevator controller is a derivative of my prototype.

Aethon Wireless Relays

January 2002- Stand-alone devices for ad-hoc relaying of communications between mobile
robots and an elevator controller (above). I selected the embedded hardware, created a
small GNU/Linux operating system and installation utilities adapted to compact flash, and
wrote the message relay software. Aethon's current version of this device is a derivative of
my prototype.

Auton Build System

-July 2001- I maintain the makefile and scripts used for building all Auton software on
various compilers, microprocessors, and POSIX-ish environments.

Auton Compute Infrastructure

-January 2000- Servers, compute machines, storage and services used by Auton lab mem-
bers for research. My responsibilities include

· hardware and software selection, procurement, and deployment

· maximizing performance for niche scientific needs on a limited capital budget in a

university environment

· maintaining vendor relationships and negotiating affordable prices

· understanding the current high-performance and consumer computing markets, both

for our needs and for occasional advisement of clients and other academics.

· maintaining software, security, and services

This collection of user and server systems is used daily and maintained constantly. Some
responsibilities have been shared with additional admins since Spring 2002.

Tomographic Reconstruction
Software

Fall 1996 Software package for reconstructing a density function over a convex polytope
using only information from (n-1)-dimensional integrals ("x-rays"). I developed this soft-
ware for a math professor to use as part of his Geometric Tomography classes.

Personal

When outdoors I enjoy soccer, hiking, travel and photography. Indoors, I dabble in electronics and use my embedded computing
experience for entertainment. I like to combine software, hardware, woodworking and metalworking to complete "essential"
upgrades to our home, including a small home theater.
