Mr. Tatom is currently employed by APT where he serves as a Staff Analyst. He has been associated with EAI since June of 1989. He currently serves as a consultant, in the area of hardware and software management and maintenance, as well as programming and application development. Mr. Tatom is also in charge of communications and connectivity, including the use of (and presence on) the Internet and the World Wide Web. 

Through his academic background and job experience, he has worked and become proficient with a wide variety of computer languages (C, Pascal, FORTRAN, BASIC and SPICE) on several types of computer platforms (UNICOS Cray systems, UNIX workstations, VAX systems, PC's, and Macintoshes). While at Auburn, Mr. Tatom studied digital control theory and application (specifically, digital filter design), digital hardware design and assembly language programming, analog and digital communication systems, signal processing, and algebraic coding theory for data transmissions.

While at EAI, Mr. Tatom has been involved in a wide variety of software applications. In the field of turbulence analysis, he participated in the development, testing, modification and documentation of both TURBAN (Turbulence Analysis) and RHOCOR (Density Correlation) software. This involved the development of algorithms to generate power spectral density and autocorrelation functions for hypersonic turbulence. Mr. Tatom participated in the development of SURPRESS (Surface Pressure Fluctuation). He was given the task of introducing compressibility into the two-dimensional version of the program. This task also required Mr. Tatom to create a process in which the PCs (DOS) at EAI connected via modem to a VAX (VMS) front-end, which submitted jobs to a Cray (UNICOS) processing queue for execution.

Mr. Tatom also has aided in the evolution of EAI's explosive safety software, HEXDAM (High Explosive Damage Assessment Model), VEXDAM (Vapor Cloud Explosive Damage Assessment Model), and VASDIP (Vulnerability Assessment of Structurally Damaging Impulses and Pressures). This effort has included producing several customized versions of EAI programs for customers with specialized needs. He was the principal programmer in the effort to produce VEXDAM 5.1, which introduced elevated vapor clouds to the existing code. He is currently working on the development of the HEXDAM Man and VEXDAM Man code, including authoring utilities which handle the placement and posing of the "man".

Additionally, Mr. Tatom has experience with EAI environmental engineering software, including SATT (Site Assessment of Tornado Threat) and RIVDIF (River Diffusion Model). He was responsible for the development of SATT 2.0, including the new features and user-interface. This task also required the revision of the techniques used to process the National Weather Service tornado data. Mr. Tatom is currently working on the Seismic Tornado Detection project, which requires the analysis of large sets of seismic data, which in turn has necessitated the creation of several utility programs to handle the large data files and to transform them into a format suitable for input to SSA (Statistical and Spectral Analyzer).
