My general research interests lie in the statistical inference of stochastic processes superimposed on stochastically evolving networks. Stochastic processes are broadly defined to include Poisson processes, Markov chains, and non-linear stochastic differential equations. Stochastically evolving networks are meant to provide the biologically realistic contexts within which our stochastic proces...

When we integrate data from multiple sources, the resulting database may contain errors and inconsistencies. Ideally, all errors should be cleaned automatically. In reality, though, data cleaning necessarily requires human intervention. To facilitate this, I envision a data integration process where it is possible to obtain meaningful and consistent answers from an integrated database even if i...

Figure 1: Protein 3W6H in wireframe (a) and in spheres (b) viewed by PyMOL. The protein is modeled as a rigid obstacle (c) and we can use a recently developed method which guarantees the sample distribution around the obstacle to generate possible binding ligand configurations with respect to the target protein (d). My graduate research focus is motion planning [4, 6] and its application in com...

The design of robotic systems that are capable of sophisticated social behavior such as cooperation, compromise, negotiation, and altruism, requires more complex mathematical models than are afforded by the classical mechanisms for making value judgments and decisions. A new concept of multi-agent satisficing, defined in terms of relative effectiveness and efficiency, is an alternative to class...

This paper contributes to the debate over land tenure in rural China by conceptualizing and measuring multiple dimensions of property rights in a way which elucidates the competing interests which are affected by the property rights regime. Utilizing a unique village level data set on property rights, this paper argues that the regional and temporal variation in rural property rights signals a ...

In this paper, we propose a notion of facilitating encounters and knowledge sharing among people having shared interests and experiences in museums, conferences, etc. In order to show our approach and its current state, this paper presents our project to build a communityware system situated in real-world contexts. The aims of the project are to build a tour guidance system personalized accordi...

Our work addresses the problem of information overload in the spatial domain. Information overload can confuse and overwhelm users by providing too much detail, often complicating simple interaction tasks. Knowing users’ interests allows the system to alleviate information overload, and therefore facilitate interaction, by tailoring the information displayed at the interface to individual user ...

Donaldson and Dunfee (1999) suggest in a brief discussion that a manager may in some cases rely on his or her own values in making organizational decisions. Our paper examines the role of diversity in values in an organizational context. Our central contention is that value diversity among managers, employees, and other stakeholders on dimensions such as prudence-boldness, clarity-flexibility, ...
