Synopsis:

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; over 12 years of 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, particularly in manufacturing.

Scientific Experience:

• Work experience with Sol Biotech Inc (5/2003 - 1/2004)
  • Began design work on an anti-freeze protein.
  • Began design work on a class of metal ion binding proteins.
  • Continued work on pyrophosphatase (see below).
  • Continued design work for the construction of molecular scale computing components.
• As a free-lance researcher (‘95):

  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.

• 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.

• 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.
