Being a mathematical physicist, I have a particular fondness for his papers in *Topology* in the 1980s, alone or with Mathai, on the subject of superconnections:

* **Superconnections and the Chern character**, *Topology* 24 (1985) 89-95

* **Superconnections, Thom classes, and equivariant differential forms**, *Topology* 25 (1986) 85-100

* **Superconnection character forms and the Cayley transform**, *Topology* 27 (1988) 211-238

All are sadly hidden behind an Elsevier paywall...
