Philip Kegelmeyer (E.E. Ph.D, Stanford) is a Senior Scientist at Sandia National Laboratories in Livermore, CA. His current interests are machine learning and graph algorithms, especially as applied to ugly, obdurate, real-world data which is, perhaps deliberately, actively resistant to analysis.

At present he leads a research effort in "Counter Adversarial Data Analytics". The core idea is to take an vulnerability assessment approach to quantitatively assessing, and perhaps counting, the result of an adversary knowing and adapting to exactly whatever specific data analysis method might be in use.

In prior work, he was the Principal Investigator for a large (forty part-time staff) "Grand Challenge" internal research and development project devoted to network analysis. Prior to the NGC he led the Advanced Simulation Computing Data Discovery Program, devoted to search in, and characterization of, petascale scientific simulation data.

Dr. Kegelmeyer has twenty years experience inventing, tinkering with, quantitatively improving, and now, subverting supervised machine learning algorithms (particularly ensemble methods), including investigations into how to accurately and statistically significantly compare such algorithms. His work has resulted in over sixty refereed publications, two patents, and commercial software licenses.
