The National Institutes of Health announced today that Dr. Murat Dundar and his collaborator, Dr. Bartek Rajwa of Purdue University, have been awarded a $385,000 grant, funded for two years. Dr. Dundar is the campus Principal Investigator for the project, entitled "Machine-Learning Approach to Label-free Detection of new Bacterial Pathogens."

This project will develop a machine learning approach that automatically detects samples of bacteria using optical scans. Purdue University researchers have recently developed a new optical sensor for detecting and identifying colonies of pathogens like Listeria, Staphylococcus, Salmonella, and E. coli. This new testing method will collect data on the patterns formed by laser light scattering on these bacterial colonies. In this way, features are extracted and used to classify samples. This method will mean that samples can now be tested without the use of chemicals and other testing equipment. The end goal is to develop testing mechanisms that allow for the identification of bacterial outbreaks as early as possible, in order to create a network of testing sites and shared databases that result in an early bio-warning system.
