Geoffrey Fairchild, Ph.D.

Santa Fe, New Mexico, USA

I am a computer scientist focused on using modern data science techniques to solve real-world activity-based intelligence problems. My toolbox includes various techniques for heterogeneous data fusion, large-scale parallel data processing, machine learning, geospatial and spatiotemporal modeling and analysis, statistical modeling, natural language processing, optimization, and agent-based modeling. Some key application areas I have worked on include: 1) disease modeling, surveillance, and forecasting, 2) political instability modeling, and 3) patterns-of-life analysis and anomaly detection.
