  CV   | Blog: Open Maze Feed )

I'm a Graduate Teaching Fellow (Assistant Professor of Computer Science @ Cal Poly Pomona starting Fall 2016) in the Computer Science & Engineering department at Texas A&M University-College Station, and I'm broadly interested in research approaches addressing  user modeling, biometrics, recommender systems & search personalization using implicit and explicit relevance feedback. My previous research experiences include Eye Tracking, Oculomotor Systems, and Natural Language Processing. I'm advised by Frank Shipman. I am a member of the Center for the Study of the Digital Libraries (CSDL). In 2012,  I did a 6 months internship at Knowledge Based Systems Inc, College Station, Texas with Perakath Benjamin and  John Hamilton to build a topic modeling based Collaborative Analysis tool for JackalFish search tool.  

 

I completed my Master's in Computer Science at Texas State University-San Marcos, in 2010. I worked with Oleg Komogortsev in the area of Human Computer Interaction on Oculomotor Systems, eye tracking and Biomertrics using eye movements. I spent the summer 2009 at Lawrence Berkeley National Lab. I worked with Cecilia Aragon (currently at UW Seattle) on a very cool eye movement based biometric project

 

In 2006,  I graduated from University of Peradeniya, Sri Lanka, with a Bachelor of Science in Computer Science (First Class Honors). I had lot of fun and learned to love research during my work with Dharmapriya Bandara on offline hand-written connected character segmentation and natural language processing.

Distributed Collection Manager  (Managing change on the web)
Advisor: Frank Shipman, Richard Furuta

Increasingly, digital libraries are being defined that collect pointers to WWW based resources rather than hold the resources themselves. Maintaining these collections is challenging due to distributed document ownership and high fluidity. This approach was informed by a study of how humans perceive changes of web pages. 

User Interest Management and Personalization 
Advisor: Frank Shipman

This research initiative addresses multi-application user interest modeling, knowledge management and personalization using Statistical Methods (Latent Dirichlet Allocation) and Latent Factor Models. 

CNS: NSDL Service to Support Personalized & Community-Oriented Navigation 
Advisor: Frank Shipman

To be useful, a Digital Library must provide its patrons with easy access to materials that is relevant to their needs. To accomplish this end, this research study is developing a Community Navigation Service (CNS) based on data collected by an Interest Profile Manager (IPM) while continuing to personalize resource presentation by way of the IPM to preserve privacy.  

2D Oculomotor Plant Mathematical Model Development (2DOPMM)
Advisor: Oleg Komogortsev

Goal:
Create anatomically accurate Oculomotor Plant (eye globe + extraocular muscles) model. 
Motivation: Improve understanding of the Human Visual System. Research new strategies for eye movement prediction for eye gaze guided computer interaction. Measuring extraocular muscle effort for usability evaluation. Neuronal control modeling for biometric research.

Biometrics - Collaboration with Lawrence Berkeley National Laboratory
Advisors: Oleg Komogortsev, and Cecilia Aragon (Berkeley Lab/UW- Seattle)

Goal:
Research new methods that allow a person's identification based on the eye movement and the oculomotor plant metrics. 
Motivation: Biometric methods employed today such as fingerprint identification and iris recognition can be technically breached by creating a model of a finger or a retina by using holographic methods. The properties of the eye movements allow to conduct a behavioral evaluation of a person potentially allowing to strengthen the security of the identification.

Physical Therapy Research - Collaboration with Department of Physical Therapy Texas State
Advisors: Oleg Komogortsev, and Denise Gobert (Physical Therapy)

Goal:
Research cognitive and oculomotor function in persons with mild Traumatic Brain Injuries (mTBI). Measure response to customized exercise including balance retraining or oculomotor training. Develop oculomotor exercises that allow to alleviate mTBI symptoms.
Motivation: Current treatment regimens fail to address the co-morbidities common to patients with mild traumatic brain injury (mTBI). As clinicians struggle to treat patients with acute and chronic mTBI, they continue to be challenged by the complex sequelae of symptoms or “symptom cluster” which includes cognitive, behavioral and physical dysfunction. This project addresses the recent evidence which suggests that a variety of oculomotor and sleep disorders are interrelated in persons with mTB and should be addressed during rehabilitative treatment protocols.

  1. 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.

  2. 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.
