Research

There are two main lines, one around pseudoRiemannian (indefinite metric tensor) geometries and one around (possibly nonlinear) connections associated to second-order differential equations (quasisprays). The former has lately concentrated on 2-step nilpotent Lie groups (see here for a nontechnical, historical overview), most recently on the conjugate locus and degeneracies. The latter includes a major extension of the Ambrose-Palais-Singer correspondence; see here for a more technical overview with some history.
