Recent Projects

Independent Day School for Dyslexic Children
Study of Cognitive Interventions for MIT Research
Led and designed a study for MIT researchers to investigate multi-sensory, and individualized classroom instructions for children with language-based learning disabilities. Developed quantitative assessments of targeted cognitive interventions. Stood up the analytics infrastructure for all research activities, production analysis and reporting. Developed all reports to analyze students’ progress, and communicated results to MIT researchers.

Large Multinational Construction Company
Mapping Accounting Codes Across Business Units and Construction Projects
Used Recurrent Neural Networks to develop language models to map cost codes based on their description across legacy construction projects. This novel technique saved > 10000 man hours of SME expertise.
