Marty O’Neill has a Ph.D. in Computer Science and a Graduate Certification in GIS from the University of North Texas, where he currently directs the Center for Computational Epidemiology and Response Analysis (CeCERA). He investigates methods to connect public health preparedness practitioners with the data they need to build efficient, effective, and equitable response plans for public health emergencies. By working closely with practitioners, he  Identifies public health requirements that can be transformed into computational problems;  Solves these problems using available data; and  Translates results to practice through system design and data visualization. Systems developed at CeCERA have been used in Texas and Los Angeles to build Medical Countermeasure Distribution and Dispensing plans in preparation for and during full scale exercises of aerosolized anthrax response operations.
