- Applied and adapted Machine Learning algorithms to group and classify users (including SVMs, Neural Nets, Random Forests, and Deep Belief Networks)- Designed and implemented data-collection efforts to improve classification- Designed and implemented analyses of the Twitter stream using Amazon Elastic MapReduce/Hadoop- Developed and implemented a personality-type based Recommendation System

Developing web-based visualization tools to help faculty/admin locate bottlenecks in their course dependencies and to help students navigate through their course requirements. Surfacing data-driven insights from student progress through their course requirements to guide curricular policy decisions.

Designing and teaching Intro to Astronomy courses.Developed and implemented inquiry-based learning experiences for class sizes ranging from 25-250 people.Read that last line again. Making inquiry-based learning happen with classes that large was a big deal.

Modeling searches for extra-solar planets.Analyzing photometric and spectroscopic data for transiting planet signals.

Modeled the formation of extrasolar planets and ran simulations of searches for them to guide observations.
