       OBJECTIVE
 
       Design and development of algorithms and software for engineering 
       and computer applications.  Specifically applications involving
       statistical methods and artificial inteligence, but generally   
       anything requiring analytic techniques.

       EXPERIENCE/ACCOMPLISHMENTS

       1993 to 1996 Attending U of AZ Graduate School: Systems Engr
       1993 to 1996 employed by TAD contracted to IBM  
       1992 to 1993 Contract to IBM Tucson/San Jose Development Labs
                      special projects on DASD subsystem performance
       1985 to 1992  IBM Tucson, AZ Development Laboratory
                       -  Defined and created major enhancements for:  
                          DCAT (DASD Cache Analysis Tool)    
                          performance predictive tool for IBM DASD
                          subsystems used worldwide for marketing
                          and support of IBM DASD activities. 
                       -  Major DCAT enhancements developed:
                           - analytic modeling techniques  
                           - new product support: 3990, RAMAC 
                           - productivity/useability improvements 
                           - runtime improvements 
       1980 to 1992  IBM Tucson, AZ Development Laboratory
                      -  Wrote detailed discrete simulation of an IBM
                         DASD cached control unit. 
                      -  Produced studies for design tradeoff and
                         performance of various cached DASD control
                         units.  The studies relied on discrete and
                         analytic simulation models.

       1975 to 1980  IBM Rochester, MN Development Laboratory
                       -  Designed and programmed detailed discrete
                          simulation of medium commercial computer
                          system (S/38).
                       -  Predicted performance during development of
                            S/38 using the discrete simulation.
       1975          IBM Systems Research Institute  NY,NY   
                       -  Studied algorithm development, queueing theory,
                          statistics, and management of programming
                          systems during 9 week course.
