I
received my Ph.D. in Computer Science from Texas A&M University
in
2016, advised by Frank Shipman. Before that, I earned M.S. degree in
Computer Science from Texas State University in 2010, advised by Oleg
Komogortsev. My undergraduate degree is a B.S in Computer Science
(First Class) from University of Peradeniya, Sri Lanka in 2006. I joined the
faculty at Old Dominion University in 2018. Before that, I was a
tenure-track faculty at Cal Poly Pomona (2016-2018). I am a recipient of 2021
NSF CAREER
award.
My
research interests lie in the use and development of data science,
information retrieval and machine learning techniques for effective and
efficient adaptive information access. I leverage cross-disciplinary
approaches to capture user intent dynamically during
information-seeking behaviors and contribute to the fundamental
understanding of human-information interaction by looking at how people
locate and use information. I enjoy connecting the dots between
disciplines and explore computational techniques to build user models
from large-scale user interaction data. In addition, I apply methods in
areas ranging from perception, cognition and psycho-physiological
measurements (e.g., EEG, eye tracking, and wearable devices) by probing
the thoughts of people conducting searches, simulating presumed
cognitive functions with computational algorithms and observing
information behavior in everyday tasks.

-
I-Gaze, Eye Guided Image Viewer Interface
I-Gaze interface is an image viewing application capable of navigating
through a set of grouped pictures (albums) using eye movements as the
primary input.
-
Automated
Classification of Oculomotor Fixation and Saccadic Behaviors.
The software contains the implementation of five popular eye movement
classification algorithms: Velocity Threshold Identification (I-VT),
Hidden Markov Model Identification (I-HMM), Dispersion Threshold
Identification (I-DT), Minimum Spanning Tree Identification (I-MST),
and Kalman Filter Identification (I-KF) and standardized behavior
scores that allow meaning thresholds and input parameter selection for
any eye movement classification method.
