Employment
December 2017 { June 2020: Connected Signals:
Senior Software Engineer
Building predictive models to predict tra c lights, bus arrival times at signalized inter- sections, and other tra c-related predictions.
Data analysis, machine learning, data visualization.
Languages: Python, C++.
Extensive experience with Pandas DataFrames.
September 2017 { December 2017: Independent contractor: Senior Software Engineer / Researcher
Continuing collaboration with Eduworks Corporation. January 2016 { September 2017: Eduworks Corporation: Software Developer / Researcher
Working on Machine Learning and Natural Language Processing problems.
Projects include automated question generation from text documents, inference in com- petency frameworks (predicting con dence levels that a particular person does or does not hold a given competency based on assertions of other competencies), detection of voice phishing attacks.
Languages: Java, Python as well as an in-house functional language. December 2012 { December 2015: Oregon State University: Post-Doctoral Researcher
Supervisors: Prasad Tadepalli, Alan Fern
Working on the Active Transfer Learning project, assisting in supervision of graduate students. Focus on multi-agent planning, hierarchical policy learning, multi-task learning, active learning, active tutoring.
Sept. 2011 { Aug. 2012: University of Waterloo / University of Toronto: Post-doctoral Fellow
Supervisors: Jesse Hoey (UW), Pascal Poupart (UW), Alex Mihailidis (UofT)
Continuation of the work on Machine Learning for autonomous post-stroke rehabilita- tion from my position in Dundee, now working closer together with the people from the University of Toronto and the Toronto Rehab Institute. Fundamental research in Bayesian Machine Learning for sequential decision problems is combined with research into practical and feasible solutions for the speci c eld of stroke rehabilitation. Feb. 2010 { June 2011: University of Dundee:
Post-doctoral Research Assistant
Supervisors: Jesse Hoey, Stephen McKenna
DyNaMo Project, an EU / Mexican government project, FONCICYT 95185
The project involves the development of a haptic-robotic device used in stroke rehabil- itation. In the project we researched and developed a POMDP model for the system, allowing a policy which balances information gathering on the characteristics of the per- son who su ered a stroke with quick and successful rehabilitation.
