Dr. Dundar received his BS degree from Bogazici University, Istanbul, Turkey, in 1997 and MS and PhD degrees from Purdue University, West Lafayette, IN, USA, in 1999 and 2003 respectively, all in Electrical Engineering.

Between 2003 and 2008 he was with the CAD and Knowledge Solutions group of Siemens Health. At Siemens Health, he was involved in the development of a broad spectrum of computer aided diagnosis/detection applications including FDA-approved Lung and Colon CAD products currently deployed in thousands of hospitals around the globe.

He has joined IUPUI Computer and Information Science Department as a tenure-track assistant professor in 2008, where he became an associate professor in 2014. Dr. Dundar has over fifty peer-reviewed publications covering areas of machine learning, data mining, hyperspectral imaging, computer-aided diagnosis, flow cytometry data analysis, bioinformatics, and information retrieval. His work so far have received over 1400 citations.

Dr. Dundar and his colleagues at Siemens Health have received the Data Mining Practice Prize awarded by ACM SIGKDD for their work on medical image mining in 2009. Dr. Dundar has also received the National Science Foundation’s prestigious CAREER award for his work on self-adjusting machine learning in 2013.

Research

Dr. Dundar's area of expertise is in machine learning with a special focus on self-adjusting models and inference, where the traditional brute-force approach of fitting a fixed model onto the data is replaced with more flexible models that can account for the non-stationary nature of real-world machine learning problems by dynamically updating data model to better accommodate prospective data in offline as well as online settings.

This is achieved by placing suitably chosen non-parametric Bayesian priors over class distributions to model not only observed classes but unobserved ones as well in an effort to perform joint classification and clustering. Scalable online and offline stochastic inference for non-parametric Bayesian models that can potentially enable self-adjusting machine learning has been at the center of Dr. Dundar's most recent research efforts.

Dr. Dundar's research has been motivated by applications from the fields of hyperspectral imaging, computer-aided diagnosis, bioinformatics and flow cytometry data analysis, and information retrieval.
