|Catherine Plaisant is a Senior Research Scientist at the University of Maryland Institute for Advanced Computer Studies and Associate Director of Research of the Human-Computer Interaction Lab. Catherine Plaisant earned a Doctorat d’Ingénieur degree in France (similar to a Industrial Engineering PhD). In 1988 she joined the Human-Computer Interaction Laboratory where she has been working with multidisciplinary teams on designing and evaluating new interface technologies that are useful and usable.
Catherine Plaisant has over 160 published papers, on subjects as diverse as information visualization, medical informatics, universal access, decision making, digital humanities or technology for families. Her work spans the interface development lifecycle, with contributions to requirements gathering, interface design, and evaluation. In 2015 she was elected to the ACM SIGCHI Academy (recognizing principal leaders in the field of Human-Computer Interaction).
With long term collaborator Ben Shneiderman she co-authored the 4th, 5th and 6th Editions of Designing the User Interface, one of the major books on Human-Computer Interaction.
PeerFinder explores the challenge of finding people like you, i.e. finding records similar to a seed record, based on record attributes AND event history. We know that users do not trust the advice of blackbox algorithms for important decision making… so we hypothesize that transparency and user control will increase the trust in recommendations based on the data of similar people.
EventAction introduces prescriptive analytics for temporal event sequences. The idea is to help users make plans based on data from similar people who achieve the desired outcome.
Visualization of transportation data: I now help the Center for Advanced Transportation Technology design or redesign the user interface of products for transportation managers and analysts. See the CATT lab portfolio (and also this older related HCIL transportation project)
CoCo (short for COhort COmparison) helps analysts compare two groups of records such as patients records or student records to find differences in the event sequences found in the groups.
EventFlow for event analytics is now used by many researchers. EventFlow allows them to 1) search for specific patterns of events 2) see an overview of all sequences and 3) simplify the data to reveal useful patterns.
Twinlist: explored how visual layout and animation can help clinicians see similarities in drug lists and rapidly make decisions about which drugs to keep and which one to discontinue.

Treeversity visualizes changes over time of dynamic hierarchical data. Users can analyze relative and absolute change over a variable in each node, as well as created and removed nodes. They can also compare non inherently hierarchical datasets, by grouping them by attributes.
Community Analysis and Visualization for “Nation of Neighbors”: This project looked at social network analysis for local communities.
Visual Analytics Evaluation : The SEMVAST project helped develop benchmarks datasets and metrics for evaluation. I co-chaired the 1st IEEE Visual Analytics Challenge for several years starting with the 1st Challenge in 2006, and still try to maintain the Visual Analytics Benchmark Repository.

Feb. 2017: I received an INRIA Visiting Professor grant to spend the months of June and July 2017 working with Jean-Daniel Fekete and his colleagues in Paris. Also looking forward to living in France again, and spending weekends visiting friends and family.
May 2016: As part of the HCIL Symposium we organized a workshop on Temporal Event Sequence Analysis + EventFlow and CoCo user group meeting. Join us on May 26!
