Mark A Coletti
As a staff scientist at the Oak Ridge National Laboratory, I am actively performing research in the areas of geoinformatics, machine learning, and evolutionary computation. My current principal research focus is on using machine learning to identify areas of human habitation in satellite imagery. I am also involved in research related to Volunteered Geographic Information (VGI) and agent-based modeling.
Previously, I was the Chair of the Penn State Postdoctoral Society, and as such was responsible for organizing career enhancement, personal improvement, and social activities for over 460 postdoctoral scholars. Also, I worked at George Mason University's Center for Social Complexity and Evolutionary Computation Laboratory where I developed an evolutionary computation C++ toolkit; a biologically inspired cognitive model for a DARPA Grand Challenge; a Joint Improvised Explosive Device Defeat Organization related multiagent simulation; an Office of Naval Research Multidisciplinary University Research Initiative Office sponsored massive multiagent simulation of pastoral and farming behavior in eastern Africa; and a geospatial extension, GeoMason, for the multi-agent simulation toolkit MASON.
Earlier in my career I worked as a senior software engineer in the Washington, DC, area on projects for the National Oceanic and Atmospheric Administration, Federal Highway Administration, U. S. Army's Materiel Command, the U. S. Army Topographic Engineering Center, and the United States Geological Survey. These projects included an expert system to correct human sourced sea surface meteorological data, an expert system for validating materiel purchases, a topographic visualization system, a road surface wear calculator, and a toolkit for spatial data format conversion.

Settlement Mapper Tool
I work for the Geographic Information Science and Technology group on the Settlement Mapper Tool, which automatically identifies inhabited areas in satellite images using computer vision techniques. My responsibilities include refactoring CUDA GPU C/C++ code and python scripts, and improving the use of machine learning and vegetation indices for identifying inhabited structures in satellite imagery. To that end, I have developed a tool that does radiometric scaling of DigiGlobe satellite imagery in about one sixth the time of equivalent commercial software. I also developed open source software, GPU Manager, that manages multiple Nvidia GPUs among multiple users. Currently, I am exploring the use of evolutionary algorithms to optimize deep learner architectures and hyper-parameters using our HPC resources, Titan and Summit.
The Eagle-I project provides a dashboard depicting the health of the United States power grid and fossil fuel pipelines. I am the principal architect of a new design for the software responsible for gathering power outage information for the over 300 power utilities in the US. This new system has cut in half the number of scripts needed, and reduced the collective polling time from over nine minutes to around five. Moreover, this new approach allows for easier maintenance; for example, it took two days to compensate for changes a utility made on its web site with the legacy system, and about 30 minutes to make the same changes with the new.
