Some recent Sentient tracks (of me getting coffee). Ground track traces are shown in red, static geometric features are shown in yellow.

Interests

• Computer vision: tracking, activity recognition, massive datasets, human motion analysis.
• Neuroscience: applications of information theory, striatal function, conservative models of motor planning, PD
• Robotics: motion planning

Recent Research

• Analysis of gait in movement disorders.
• Learning to recognize events
• Recovering global properties of large data sets.
• Biologically Inspired Cognitive Architectures
• Understanding the nature of information flow through the striatum.

Software Systems

SRI systems that I use most actively:

• Sentient Environments:Video tracking and event analysis.
• FREEDIUS (Maintainer, with Lynn Quam)
• MTD: the VIVID moving target detection system (Contributor)
• PCE: the Probabilistic Constraint Engine
• LAW: the Link Analysis Workbench
• SHAKEN: Knowledge Entry System for Subject Matter Experts

Relevant Expertise

• Using Lisp to manipulate and analyze the contents of SQL databases (for Sentient Environments, LAW).
• Using OAA to communicate with CALO components (for PCE).
• Programming: Lisp, C/C++, sometimes Java (other languages, rarely)
• SIMD programming: MMX, Altivec, CUDA
• Timebase management using NTP (and maybe other methods)
• Video event ontologies (for knowledge-based event analysis)
• OpenGIS tools (for ingesting GeoTIFFs, Shapefiles, etc.)
