Khalil Anderson
Student Track: Artificial Intelligence
Research Area: HCI
Advisor(s): Worsley, Marcelo
Cohort: September 2018
Research Statement: Interests in how Machine Learning can help augment, not necessarily replace, humans in tasks and jobs such as driving, learning, manufacturing, and many other areas. My current research focuses on HCI and Multi-Modal Analytics. In these areas, I hope to analyze and change the different ways Multimodal Analytics is currently approached to better integrate the wants and needs of those who are participating in collection. In doing this I hope to develop new algorithms and interactions that combine different modalities that aid in serving those needs we see from the participants.

Govinda Dasu
Student Track: Interfaces
Research Area: HCI
Advisor(s): Zhang, Haoqi; O'Rourke, Eleanor
Cohort: September 2018
Expected Graduation Date: 2025
Research Statement: My research investigates how we can take readily available open source codebases (i.e. GitHub, web source code) and convert them into opportunities for novices and intermediate developers to learn about how design patterns and architectures are applied in practice. By comparing novice use of both debugging tools (i.e. Chrome DevTools) and graphical tools (i.e. call graph visualization tools, I have found that tools can significantly shape the ways novices explore professional code, and their focus and learnings. We have introduced Scaffolded Exercises, a tool that scaffolds novices as they understand Javascript variable transformation that leads to DOM changes, and Knowledge Maps, a tool that helps novices compare and contrast examples to understand conceptual differences between techniques and build out a map of their CSS knowledge. Finally, we are actively developing RALE Modules (Readily Available Learning Experiences), a process management system which highlights and annotates design patterns and architectures (i.e. MVC, Mixins) in professional python codebases, and generates a series of diagrams and activities that help intermediate developers understand how and why particular patterns are applied in particular professional use cases.
