Some selected pieces of work
Agent-E
A hierarchical web agent for complex, multi-step browser tasks. Agent-E combines planning and execution, filters noisy page structure, and tracks changes between actions; its paper reports 10–30% stronger performance than prior state-of-the-art agents across most WebVoyager categories.

Shared gaze and collaboration
Studies how remote instructors and learners build shared attention during mobile video collaboration. The work compares gaze-sharing configurations—including whether instructors can see their own shared gaze—to understand how gaze cues affect coordination.

VR & haptics
Explores gaze as a pointer for virtual-reality interaction, paired with hand movement or dwell to select targets and force feedback to make spatial interaction tangible. The studies test ways to navigate and interact without relying on hand movement for every action.

MathViz-E
A natural-language math visualizer and solver that coordinates specialist math solvers with graphing tools to turn prompts into accurate visualizations. The research also introduces task-specific datasets and an automatic evaluator that checks outputs against known expressions.

GazeTorch
GazeTorch brings a remote helper’s gaze into video-supported physical tasks, using a spotlight to show the worker which object their partner is looking at. It explores gaze as a practical cue for coordinating hands-on work at a distance.

Little Bear
A gaze-aware learning companion built around a game for early-childhood learners. The research explores gaze as an input for play and compares the gaze-aware experience with a touch-based version.

Accuracy of Interpreting Pointing Gestures
Examines how accurately a remote observer can interpret pointing gestures from a first-person camera view. The work focuses on the perspective mismatch between the person pointing and the person watching—a key challenge for remote collaboration.
