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 self-adjusting models and inference, 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. 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
my most recent research efforts. My research is
mainly driven by real-world problems in computer aided
diagnosis/detection, hyper-spectral data analysis and
remote sensing, flow cytometry data
retrieval, and topic modeling.

I am actively recruiting graduate
students who have keen interest in machine learning and
data mining and their applications to problems in life
sciences. An ideal candidate should have a BS in CS/ECE/Math/Stats
and have a strong background in linear algebra,
calculus, probability and random variables. Extensive
experience with Matlab/C programming is also required.
