Investigated the influences of monocular and binocular visual cues on estimates of 3D orientation
when grasping and placing objects and found that relative processing speeds affect how different
cues are combined when planning and executing visually guided movements. Examined how
visual cue integration strategies for motor control are affected by task demands and how they
change when information arrives from different positions across the visual field and from
different depths relative to fixation. Developed a computational model that simulates a population
of binocular visual cortical neurons and decodes the activity patterns to quantify the amount of
information orientation disparity, a binocular visual cue, provides about 3D orientation.
Real-Time Systems Group, Air Defense
Systems Department, Johns Hopkins University Applied Physics Laboratory, Laurel,
MD
Computer Scientist/Software Engineer
November 1999-July 2002
Created ship-based sensor displays and controls, and, as technical direction
agent for the project, oversaw development and testing, assisted with problem
identification and resolution, evaluated requirements, and acted as primary
point of contact at JHU/APL. Modified 3-D visualization tools to support live
participation in military exercises, developed simulation software for combat
system testing, and created a web-based scheduler to manage facility resources.
Collaborated as part of a rapid prototyping and concept development team
researching topics in computer vision and image processing.
Center for Human Modeling and Simulation,
University of Pennsylvania
Undergraduate Student Researcher
September 1996-May 1999
Developed real-time animated conversational human agents, created tools to
manipulate 3-D polygonal objects, and experimented with various aspects of facial
animation using deformable face models.
Management Department, The Wharton
School, University of Pennsylvania
Research Assistant
February 1998-May 1999
Performed data analysis using structural equation models and various statistical
tests to determine the impact of human resource practices on hospital performance
during downsizing and reengineering for an American Hospital Association-sponsored
study. Administrated data collection and managed hospital contacts.
