Michelle is a co-founder and CEO of Juji, Inc. Prior to starting Juji, Michelle was a senior manager of the User Systems and Experience Research (USER) group, part of IBM Research, Almaden and then part of the newly formed IBM Watson Group. She also worked at IBM T. J. Watson Research Center and was on an international assignment at IBM Research, China. Michelle received a Ph.D. in Computer Science from Columbia University. Her expertise is in the interdisciplinary areas of intelligent user interaction, smart visual analytics (2D/3D), and people-centric information systems. Her work has been incorporated into or created over a dozen IBM products and solutions. She has also published over 80 peer-reviewed, refereed scientific articles, and filed over 35 patents in above areas.
Michelle is an ACM Distinguished Scientist and is active in several research communities, including intelligent user interfaces (IUI), information visualization and visual analytics, and multimedia (MM), where she has co-organized/co-chaired conferences and workshops, and often serves on the technical program committees for key conferences in these areas. She was the general conference co-chair for ACM Recommender Systems 2014 and ACM IUI 2007, and is the technical program co-chair for ACM MM 2009 and IUI 2010. Currently she chairs the IUI steering committee, and has been on the editorial board of three ACM journals: ACM Transactions on Intelligent Systems and Technology (TIST), ACM Transactions on Interactive Intelligent Systems (TiiS), and ACM Transactions on Multimedia Computing, Communications, and Applications ( TOMCCAP).
Although Michelle's research interests have evolved over the years, she has always been interested in the interdisciplinary area of intelligent user interaction (IUI) and its applications to real-world problems. In particular, her works has fallen into several areas.
One picture is worth a thousand words. For thousands of years, people have been using information graphics—visual representation of data—to comprehend and analyze information. However, creating high-quality visualization is a daunting task especially for people who are neither graphic artists nor computer scientists. To democratize the use of visualization, Michelle has been investigating how to automate the design and generation of visualization since her Ph.D. thesis.
Licklider in his Man-Computer Symbiosis said: "Man-computer symbiosis is an expected development in cooperative interaction between men and electronic computers. In the anticipated symbiotic partnership, men will set the goals, formulate the hypotheses, determine the criteria, and perform the evaluations. Computing machines will do the routinizable work that must be done to prepare the way for insights and decisions in technical and scientific thinking.”
Michelle believes that the future of HCI is to facilitate the development of such a man-computer symbiosis where both humans and machines can leverage their strengths and avoid their weaknesses. One of such developments is the support of mixed-initiative interaction where both users and systems can take initiatives during a complex interaction process.
To enable computers to take sensible initiatives and push this class of systems to main stream applications, Michelle was particularly interested in developing novel and practical computational approaches to the problem. So far she has investigated the use of optimization-based approaches and developed a suite of algorithms to address a range of fundamental challenges in the space (e.g., an algorithm for dynamically determining data content in response to a user data query in context and a graph-matching algorithm for media allocation). Going forward, Michelle is interested in exploring new interaction paradigms where users can interact with complex system responses (e.g., system-derived text summarization results) and the use of interactive machine learning in support of an adaptive, mixed-initiative human-computer interaction, where both humans and computers can learn from each other.
The use of social software (e.g., social networking, micro-blogging, and online forums) has penetrated the masses. Michelle was inspired by the phenomena and interested in finding out how it will change people's daily lives as well as its long-term impact on the world. In particular, Michelle was interested in how social computing will bring people with opportunistic information and collaboration partners whenever they need them but without subjecting themselves to "constant availability and instant intimacy" as they do today. For example, when a person has a question regarding car repair, through social media she should be able to locate a person/group who has perhaps just had his/her car repaired and is able to provide her with the most accurate information to her inquiry; if someone wants to find a person to share a rental car at a tourist destination, again through social media they should be able to find such a partner whom they do not know before but they now share the same interest/need at that moment. To support these scenarios, Michelle believes there are fundamental research issues to be addressed. They include but not limited to:
At IBM Research, Almaden, Michelle initiated and led her team in developing System U, a personality analytics system that can automatically derive an individuals' personality traits from the individual's linguistic footprints (e.g., tweets, blogs, and reviews). Such derived traits can then be used to help an individual to better understand him/herself as well as others to obtain or deliver hyper-personalized experience (e.g., self discovery/assessment, social engagements, product or career recommendations). Not only such traits can be used to improve human-computer-human interaction, but they can also be used to facilitate human-computer interaction, as one's psychological traits, may aid one's information tasks, e.g., information navigation and visual perception/interaction of information. System U now is known as Personality Insights offered by the IBM Watson Group.
Since System U has showed great promises in deep people understanding, Michelle believes that the biggest value of such technology lies in its applications, especially those that can benefit hundreds of millions of individuals directly. Imagine a world where everyone knows who they really are, easily find opportunities that value their individuality, and discover experiences that delight them. To pursue her passion about applying deep people analytics to helping individuals, she decided to co-found Juji last fall.
