Dan Gruen is a Cognitive Scientist in IBM Research's Symbiotic Cogntive Systems group.  He works on the design of cognitive environments, such as Cognitive Boardrooms and Cognitive Control Centers, to let strategic decision-makers seamlessly incorporate insights from big-data, analytics, visualization and cognitive systems.   Dan led a team that developed collaborative reasoning tools, and that also created an early mobile, geo-data crowdsourcing app.  

In the past, Dan managed IBM Research's Reinventing Email research project, was an early researcher on activity management, and has done research on visualizations , spatial displays and mobile devices.   He has worked with numerous customers to help create technology visions aimed at their desired business outcomes.

Dan has a PhD in Cognitive Science from UCSD.  He holds over 30 US and international patents in User Experience, Social Software, and related areas. His work includes the use of visual scenarios and other story-based methods to ground design in real-world usage situations.

Dan applies his background in user-centered design and experience with observational methods to a variety of areas, including:

    • fluidly merging informal work with structured business processes,
    • new approaches to email and integrated messaging,
    • tools to help users manage multiple activities,
    • innovative ways of linking computer-based information with the external world.


Dan's thesis research at UCSD, conducted under Don Norman and funded by Apple Computer, involved detailed observational studies of how people manage multiple activities and handle interruptions. His earlier research investigated trade-offs in the design of graphical representations.
Dan has consulted on usability and interface design for a variety of applications, including digital television, telecommunications, and computer-assisted design. He has also taught courses on user-centered design techniques in university and corporate settings.

Previously, Dan worked as a Vice President at Merrill Lynch, responsible for the design of trading support systems.
