Research Interests

Statistical Physics
Phase transitions and critical phenomena, particularly the effects of disordered geometry on the universal and non-universal behaviors exhibited by systems at or near a critical point. Current projects include the study of transport and vibrational spectrum of disordered systems, and statistics of self-avoiding walks. Specific examples: high density percolation and quantum percolation, and statistics of interacting polymers. Examples of method used: Monte Carlo simulations and eigenvalue analysis by Arnoldi methods. We now calculate the conductance of such networks directly using transport theory.

Physics Education

Effectiveness and implications of various digital tools of education such as computerized homework systems. Especially, how computerized, interactive tutorials augment or interfere with some of the measures intended to gauge students' learning including the exams, homework, and concept inventories. Also of interest is how such effects may or may not depend on the attributes of the students including gender, prior exposure to the physics topic, and their own outlook on physics learning.
