Presently I am working on solid sweeping. The problem of computing the envelope of the sweep of a given solid moving along a given trajectory
is a classic one. I am trying to get a parameterization of the envelope. More details here. One of the several applications of solid
sweeping is design of conveyor screws. A video of a conveyor screw in action can be seen here.
I have also worked on learning to rank for information retrieval in the past when I explored conditional models for ranking loss functions and efficient
local learning for ranking.
