Biography and Current Activities

Dennis is currently Associate Professor of Informatics, and the Associate Dean for Undergraduate Studies for the School of Informatics on the Bloomington campus. His responsibilities include curricular programs, student services, advising, academic operations, and career services.

In addition to his Informatics responsibilities, Dennis was recently appointed as Associate Vice Provost for Undergraduate Education for Indiana University Bloomington. In this capacity, he is responsible for a variety of critical campus programs, including curricular procedures, outreach, service learning, continuing and adult education, course evaluation processes, and test administration.

My research focuses on the development of new database access and data mining techniques in support of data visualization activities. I am particularly interested in exploring ways in which visualizations can be manipulated in the same fashion as the data that generates the visualizations. Creating such techniques will enhance the ability for users to explore the visual space, thereby improving the knowledge discovery process.

Dennis has more than 15 years of experience in the software development industry. He has designed and developed systems for healthcare, pharmaceutical sales, and financial services applications. He applies his industrial management experience in the senior capstone course, in which student teams develop an information system based on the requirements of a real customer.

Projects

Information Provenance - This project explores how exploration occurs with data. In particular, the transformations, views, observations, and annotations that occur while users explore data are recorded, and then made available to them for collaboration, or further exploration.

Query Structure Visualization - This project develops visualizations of the structure of queries - not the data returned by the queries. Through this work we seek to develop a better understanding of data through the questions that are asked of the data.

Mobile Visualization of Data - This project couples the generation of visualizations with mobile devices that enable groups of users to collaborate. We are developing a framework for group annotation of visualizations using new interaction mechanisms with, in particular, tablet PC's.

Undergraduate Capstones - Every Informatics undergraduate student must complete a capstone project. I am responsible for overseeing many of these projects in the I450/I451 Designing and Developing an Information System course. Capstone Project Descriptions
