Multisensory Integration in XR (Thesis Topic, 2019-2020)
For my dissertation, I proposed a new category of congruency effects for audio-visual integration, that could be used to improve processing of complex XR environments. I assessed the impact of these congruency effects, and found them to have a significant effect on the extent to which participants experienced crossmodal illusions. These results indicate that these action-object congruency effects could be utilized to improve multisensory integration in XR.

Accessible Educational Tool Design (2017, Lab Project)
I helped create a taxonomy of data and interaction types present in the PHeT educational tools, to facilitate the creation of general guidelines for how such tools could be made accessible. I also oversaw a student team who investigated the use of the Leap Motion device to create accessible versions of the tools using air gestures and audio.
Visualizing Movement of Voters on Election Day to Assess Polling Place Accessibility (Class Project, 2018)
In this class project, I utilized a set of deidentified location data to plot and analyze voters traveling to polls on election day.
Design of a Training Program to Teach Sight-Reading of Music (Class Project, 2016)
Eye-Tracking Social Media (2015, External Activity)
I worked with a local company to design eye-tracking research into the way viewers assess social media profiles.
Spatial Screen Sharing (2013, Class Project)
An experiment in passive spatial interactions over a network. I designed and prototyped a system that allows for remote screen sharing of a separate, constantly accessible ‘space,’ for use by family members or friends. This was written in python for a class assignment.
Great Circles: Small Group Car Sharing (2012, MS-HCI Foundations Class Project)
The goal of this project was to decrease the barriers to co-ownership of a vehicle by a small group of people through the use of a status, scheduling and management system. The project involved initial research, design, prototyping, and evaluation of the system. I worked with a small team to carry out and document the project over the course of a semester, with a personal focus on research design, project management, and information architecture.

I conducted a human factors analysis of several portable oxygen concentrators. The goal was to produce a report which could be used to improve the safety of future devices.
Modeling Error in 2D Pointing Tasks (2012, Undergraduate Thesis)
My Honors thesis project, I developed a model of systematic undershoot in pointing tasks while working in the Computer-Human Interaction Lab at Rice. The ultimate goal of this research is to build a more valid goal-directed movement system into the ACT-R cognitive architecture, which can be used to predictively model human performance in user interfaces. The work included research design, user testing, data processing and interpretation, and literature review.
