2012 - Present
Visual Cognition Laboratory, Northwestern University

Graduate Student Researcher, Advisor: Steven Franconeri, Ph.D.

  • Designed, programmed, implemented, and analyzed data from laboratory experiments to investigate how to improve data visualizations.

  • Used psychophysical methods and eye-tracking to test >300 experimental participants.

  • Developed and implemented research protocols in collaboration with computer scientists at UW Madison (4 years) and Tableau (2 years).

  • Supervised 6 research assistants with testing participants, experiment programming, data analysis, and publication writing.

  • Novel findings: 1) Attention to a collection of objects is more efficient when those objects differ from other (irrelevant) objects within multiple feature dimensions, such as color and shape, than when they differ by only one feature, such as only color or shape; 2) Perception of relationships between data points in common graph formats is strikingly inefficient, but improves significantly when the those data relationships are directly represented (e.g., a single bar representing the difference between data value pairs, rather than a bar for each data point). 3) People can accurately perceive up to 4 high-frequency peaks in a line chart.

 

2010 - 2012
Cognitive Neuropsychology Laboratory, UC Berkeley

Post Bachelor Study / Lab Manager, Advisor: Lynn C. Robertson, Ph.D.

  • Managed large electroencephalography (EEG) study by coordinating testing with international collaborators, testing participants, and analyzing data.

  • Collaborated on study of large group of post-stroke patients, tested patients in hospital setting, prepared data for analysis, and maintained database.

  • Trained 6 research assistants to run EEG recording sessions.

  • Supported principal investigator and lab members with daily administrative and technical assistance across two lab sites.

  • Novel findings: People who demonstrate a relatively early N170 ERP component in response to viewing a face tend to recognize faces better.

 

2008 - 2009
