Introduction:

    Keith Oxenrider has a diverse background (business management, biotechnology,

    production management, and computer optimization) that he is eager to bring to bear on

    solving complex problems. He has developed a strong interest in using sophisticated

    programming techniques (such as Evolutionary and Genetic Algorithms, Genetic

    Programming, and Machine Learning) to provide solutions to problems that are currently

    handled by human experts. With a very strong technical background (BS Biochemistry

    with over seven years laboratory experience; since '96 programming and project

    management experience on Windows and UNIX (mostly Solaris and Linux) platforms

    including more than 60K lines of C++ in more than 270 source files and 240 objects and

    on MS SQLServer/Sybase over 14K lines of SQL including more than 100 stored

    procedures), Mr. Oxenrider is well prepared for quickly assimilating new situations and

    developing novel solutions to complex problems. With an MBA and experience as a plant

    manager Mr. Oxenrider is also well suited for interfacing with management at all levels.

    For two years he was 'elected' a Microsoft's Most Valuable Professional in the C++

    category (MVP, 2003-2005).

    o Success with the initial portion of a shop floor data collection system called Production Data

    Interchange (PDI) lead to a call from senior plant management to extend PDI throughout the entire

    plant’s manufacturing process. The extension of PDI reached the stage where almost 80% of the

    manufacturing was under tracking control of PDI and the remaining 20% was expected to be included

    by Summer 2001. This system includes the use of hand-held scanners accessing the network via a

    remote frequency (RF) radio interface. The PDI system was documented to reduce headcount by 8

    and save over $300,000 per year in labor costs.

    (PDI), interface with a SQLServer 7.0 database with near real-time visual display of collected data. o Acted as DBA for SQLServer 7.0 database during development, including the writing of stored

    procedures and triggers, loading data, and ensuring backups and other database maintenance. o Designed a Java application (Java version 1.1.6) to track work hours by developer and project.

    Application places this information into a restricted access database via password authentication.

    ; At Vector Research: (11/96 - 5/98)

    o Managed design and development of Lotus Notes in-house marketing information database. o Team Leader for a group (9 people of diverse backgrounds) tasked to develop marketing material

    lauding the past works of Vector Research and projecting their Solution Capability into the future. o Deputy Director of Testing and Technical Lead. Provided mentoring and motivation for testing

    o Initiated and developed an in-house marketing proposal to build a Materials Requirements Planning

    software package that included a built-in optimizer based on the Evolutionary Production Sequencer

    (Please see www.sol-system.com/eps).

    Keith Oxenrider’s Resume 4

    o Beginning first as assistant project leader, became acting project leader when current leader began 3-

    month maternity leave. Managed the flurry of activity surrounding the run up to product release, then,

    when the release was put on hold, wrote a plan to address the perceived shortcomings of the product.

    Put into place the approved changes to the existing product.

    o As Testing Technical Lead, designed and implemented scripts and C programs to enhance the

    reproducibility of testing process and to allow creation of test data that contained the entire range of

    expected and the expected unexpected values.

    o Wrote a program to compare data stored in an ASCII file (containing more than 2.7 million records)

    with the contents of other ASCII files and modify those other files based on matches found in the first

    file. The C program processed more than 2,500 files containing more than 1.5 gigabytes of information

    in 3 hours.

    o Prepared strategic management analysis on Genentech, Inc. (among the first biotech companies formed,

    and still among the largest in size and revenues.)

    o Prepared business plan for creating a management consulting business focusing on facilitating business

    between US and Chinese companies.

    o Designed and developed a C application called The Evolutionary Production Sequencer (Please see

    www.sol-system.com/eps), an algorithm for sequencing product launch orders for a mixed model

    assembly line. Required the creation of code to simulate an assembly line environment both with and

    without components being built in a Just-In-Time manner. Required the creation of new evolutionary

    algorithm modules in order to successfully evolve toward a solution. This research has led to two

    published abstracts and a full paper in Decision Sciences (See below).

    ; Experience gained on own:

    o (2004/2005) Wrote applications to dynamically write binary instructions to memory and execute them.

    Please see http://sol-biotech.com/code/SelfModifyingCPUID/SelfModifyingCPUID.c for a C version

    Keith Oxenrider’s Resume 6

    A second (first described below) de novo protein project was begun in spring of 1995 to

    design and express a synthetic anti- freeze protein. After similar design work as below, the

    gene was created by ligation of overlapping oligos, inserted into an E. coli plasmid and the

    production of the protein was induced. This effort was rewarded by the production of large

    (2-5% total protein) amounts of the de novo protein.

    o As a student in the Master of Biochemistry program ('93-'94):

    Thesis project was to design and express a de novo protein that would fold into a three

    dimensional form that would have an active site for the catalysis of pyrophosphate into

    phosphate. The protein was first designed with accurate physical plastic models, then

    translated into coordinates to be used in a computer model. The computer model was

    subjected to simulated annealing. Modifications to the primary structure of the protein were

    made until the simulation indicated that the structure was stable. The primary sequence of the

    protein was translated into codons common to highly expressed E. coli proteins, oligos

    selected to represent the gene of the protein, the oligos PCRed to create the gene. After the

    gene was inserted into an E. coli plasmid the sequence was verified and the protein was

    induced.

    o As a student and as a full-time laboratory employee (‘89-‘93):

    Various experience working with molecular biology techniques; DNA sequencing; PCR;

    extensive experience working with radioisotopes; normal and transformed animal cell culture;

    Archeabacterial, bacterial, and yeast cell culture; and protein purification. o Published 4 papers. (See below)
