I received my 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 I was with the CAD and Knowledge Solutions group of Siemens Health. At Siemens Health, I was involved in the development of a broad spectrum of computer aided diagnosis/detection applications including FDA-approved Lung and Colon CAD products. I have joined IUPUI Computer and Information Science Department as a tenure-track assistant professor in 2008, where I became an associate professor in 2014.


My area of expertise is in machine learning with a special focus on open-world machine learning, where we aim to replace the traditional brute-force approach of fitting a fixed model onto the data with more flexible models that can account for the non-stationary nature of real-world machine learning problems. We achieve this 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. Deep feature learning has recently become an important component of my research in open-world machine learning. How to learn a feature embedding that is specific enough to discriminate observed classes but also general enough to accommodate a large number of unobserved classes? How to develop loss functions that are not biased towards observed classes? How to take advantage of class descriptions or other side information to discover and model unobserved classes? These are some of the deep machine learning problems I have been working lately. My most recent research projects involve axon segmentation in electron microscopy images, mineral mapping on Mars using orbital data, describing the undescribed species using images and DNA, authorship attribution in historical texts.
