Dr. Denenberg's research interests focus mainly on Human-Computer Interaction, Social Computing, and On-Line Communities.

Currently, Dr. Denenberg is finalizing the structure of the Information Layering Protocol, which allows systems designers to formally notate and identify multiple communication layers within a single presentation channel. This will lead to a better understanding of the way a user interprets information displayed and uses that information for decision making, especially in the context of time-critical situations.

Additionally, Dr. Denenberg is investigating the effects of color coding and layering on the interpretation of complex, multi-layered email messages. As the message becomes more and more complex, with more layers of response prefaced by a multitude of brackets, color coding provides an easy and cognitively relaxed method of interpreting, searching, and responding to complex email communications.

With the emergence of the tablet PC as a viable alternative to the more cumbersome notebook computers for people who work in a mobile or remote environment, such as nurses, real estate agents, or construction workers, Dr. Denenberg is currently involved in a research project that evaluates and compares the speed and accuracy of tablet PC input methods to notebook and desktop computers. This research will assist in establishing the viability of the tablet PC as a means of streamlined information gathering for workers who need access to information while at the same time being able to provide it in a mobile environment.
