Another colleague and I iteratively coded the posts to identify 23 themes characterizing the different kinds of questions posed by patients. We clustered the themes under
Since Spring 2016, I have designed, conducted and analyzed data for 4 lab studies with a total of 60 users under the guidance of Prof. John Stasko at Information Interfaces Lab . Three of the four studies were focused on summative evaluation of a tablet information visualization system to understand how presentation and interaction design strategies influence system learnability.
