On the Complexity of Join Predicates
We consider the complexity of join problems, focusing on equijoins, spatial-overlap joins, and set-containment joins. We use a graph pebbling model to characterize these joins com...

Complexity in geometric SINR
In this paper we study the problem of scheduling wireless links in the geometric SINR model, which explicitly uses the fact that nodes are distributed in the Euclidean plane. We p...

Supporting Complex Thematic, Spatial and Temporal Queries over Semantic Web Data
Spatial and temporal data are critical components in many applications. This is especially true in analytical domains such as national security and criminal investigation. Often, t...

The Complexity of Model Checking (Collapsible) Higher-Order Pushdown Systems
We study (collapsible) higher-order pushdown systems -- theoretically robust and well-studied models of higher-order programs -- along with their natural subclass called (collapsi...
