Education

PhDInformatics, University of Edinburgh, 2008. I completed my PhD in the Centre for Speech Technology Research under the supervision of Steve Renals. Here is my PhD thesis, Using Speech-Specific Characteristics for Automatic Speech Summarization.

MSc.Speech and Language Processing, University of Edinburgh, 2004

BALinguistics, University of Washington, 2003

Teaching Interests

At UFV, I regularly teach upper-level courses in the areas of AI and Data Mining (e.g. COMP 380 Intro to AI, COMP 381 Machine Learning, COMP 455 Extreme Computing, COMP 482 Natural Language Processing, COMP 331 Data Quality). I also teach introductory programming courses (e.g. COMP 120 Computing for the Sciences, COMP 155 Object Oriented Programming).

Research Interests

Speech and natural language processing, computational linguistics, multi-modal interaction, sentiment analysis

Artificial Intelligence, machine learning, belief networks, markov decision processes, markov rewards processes

Data Quality, data mining, statistical process control, Bayesian statistics

Computational Social Science, Complex Adaptive Systems, small group interaction
