The National Science Foundation's Division of Earth Sciences has hired two new rotators to serve as program directors, as part of the ongoing visiting scientists program. The new directors are Jonathan Fink in Geochemistry and Petrology, and L. Douglas James in Hydrological Sciences.

Fink has exchanged roles for 1 year with NSF's John Snyder, who is on sabbatical at Arizona State University. Fink's current research includes studies of how the Theological properties of magma govern the emplacement of volcanic domes and lava flows, and the gravitational control on their mass movements. This research extends to the mechanisms of igneous intrusion and interpretation of volcanic features in extraterrestrial and submarine environments.
