Technical team management. Managed a 22 person technical team and a six person team at previous positions. Reported to the Executive Director in both positions, providing budget and work program for each agency. I excel at creating motivated technical teams by providing guidance, mentorship, and skill-building.
Agent-based and activity-based modeling. Deep familiarity with MATSim and ActivitySim. Developed SimWrapper, a web-based dashboard tool for analyzing MATSim and ActivitySim outputs.
Programming languages. Over ten years experience writing advanced Java, Python, TypeScript, R, C, and C++. Built successful Android mobile applications in Java. Taught introductory Python and R courses.
Data analysis. Expert in web-based data visualization techniques including Deck.gl and three.js. Expert in the R/Tidyverse data analysis platform. Comfortable with Python/Pandas.
Front end web developer Modern web front-end developer, expert in Vue.js and familiar with React. I have built countless single page application websites, from internal tools such as timesheet and expense report creators to full data analysis portals including 3D animations and map-based visualizations.
Other technical skills. Expert in Git and code management. Vast experience with setting up data flow pipelines. Very comfortable with Docker and related DevOps technologies. I consider myself a technology generalist: I am very familiar with many technologies and can pick up others quickly.
Developed new 3-credit course for VSP department, focusing on R for data science, including exploratory data analysis, data visualization, and online publication of results.
One-day workshop for scientists as part of Software Carpentry workshop series.
Developed and led afternoon workshop on collaboration with Git, based on Software Carpentry workshop series.
Chair of the Board, Zephyr Transport Foundation, 2018-2020.
Certified Volunteer Teacher, Software Carpentry Organization.
Reviewer for Transportation Research Board ADB40/AEP50.
