Responsibilities as Principal Investigator:
 Planning, implementing and publishing results of research.
 Managed yearly budgets ranging from 300K-600K.
 Supervised computer programmers, research assistants and technical support staff from
DOD, Industry and Academia.
Products and Topics of Research:
 Choquet Integral:
 Used Choquet Integral as fusion operator to aggregate interacting criteria to
accomplish multi-criteria decision-making and rank Naval Surface Assets for re-
deployment for unscheduled missions.

2.  Queueing Theory (Systems of Flow):
 Used Queueing Theory to develop quantitative models of operator and system
performance that form the basis of scientific design of future Naval Combat Systems:
Supervisory Control of Unmanned Autonomous Vehicles; Air Defense Multimodal;
Watchstation, and Land Attack Weapons System.
 Queueing Models entail Modulated Markov Poisson Processes (MMPP arrival),
Erlang Service processes, finite length queues, infinite length queues, balking,
reneging, and vacationing server, queueing networks, first-come-first-serve, random,
and priority queueing policies. Verified queueing model predictions with MATLAB
simulations.
 Combined Queueing Models with Bayesian Networks to develop a model of
operator cognitive capacity in complex supervisory control environments with
heterogeneous Unmanned Vehicles.
 Artificial Intelligence:
 Developed an Expert System, Theory of Affordance Design Analysis (TADA!),
which mimics the feedback provided by a Human-Computer Interface (HCI) design
analyst.
 Developed Cognitive Architecture that represents human perceptual and cognitive
capabilities critical to apprehending interface “affordances.”
 Attention Allocation Systems:
 Measure and evaluate the degree to which change blindness and inattentive
blindness occur in human-computer interface environment.
 Test and demonstrate the impact of change blindness and inattentive blindness in
the context of naval tactical console operator part-task simulations.
 Digital Image Processing and Computer Graphics:
 Developed a colorization algorithm that compressed passive acoustical data by a
factor of 4:1. Generalized algorithm to the visualization of scientific data.
 Tested the effects of various signal processing techniques on the detectability of
critical features in visual displays of Low Frequency Analysis Recordings.
(Collaborators: Johns Hopkins University Applied Physics Laboratory.)
 Virtual Environments:
 Collaborated with Armstrong Laboratories Wright-Patterson Air Force Base on a
scientific data visualization project which presented 48 bearings of passive acoustical
data in a helmet mounted display.
 Developed a 3-D acoustical “fly-thru” in collaboration with Armstrong Laboratories.
Rendered acoustical data from the Active Tactical Decision Aid into a 3-D visual
display of the acoustical environment.

3.  Signal Detection:
 Applied Signal Detection Theory to compute the ideal detector for 1, 2 and 3 bit
quantization of scientific data for visualization on CRT displays.
 Compared human efficiency to detect signals to ideal detector’s performance.
 Basic Vision Research:
 Explored, in visual search experiments, the early perceptual organization of object
attributes and the preattentive binding of attributes to objects.
1983-1984: J. P. Sloan Post Doctoral Fellowship, Massachusetts Institute of Technology,
Center for Cognitive Studies.
 Studied Computational Vision, Cognition, and Artificial intelligence.
1978-1983: Research Assistant, Rutgers University.
 Worked in Professor Irvin Rock’s laboratory. Topics of investigation included:
 3-D Form perception, Motion and Velocity perception, Anorthoscopic perception, and
Attention.
 Operated eye-tracker and programmed in Assembly language, FORTRAN and C to
generate experiments and graphics on computer displays.
