Bio
I am an Assistant Professor in the Visualization @ Khoury group, part of the Khoury College of Computer Sciences at Northeastern University. Prior to joining Northeastern University, I was a research scientist in IBM Watson Health, IBM Watson and IBM Research. I received my PhD and MS degrees in computer science under Ben Shneiderman at the University of Maryland Human-Computer Interaction Lab in 2013 and 2009, respectively, and earned a bachelor's degree in computer science and mathematics from Cornell College in 2007.
My work crosses components of data visualization, human-computer interaction, network science, and computer science. I focus on helping people explore and understand complex data—in particular, data that combines aspects of network topology, position in space, values of attributes, changes to all of these over time, and how changes or events can happen in sequence. Much of my research is motivated by the real-world problems users face. Some of the areas I have worked on include healthcare diagnostic and treatment decision support; understanding and preventing cybersecurity incidents; building computer network resilience; interpreting results from natural language processing, database, and computer engineering research; exploring how scientists collaborate; mapping the spread of infectious diseases; and understanding relationships within archaeological dig sites.
