research centers on past, present and future global change, and is variously
involved with light stable-isotope analysis of tree rings, native plant
leaves, crop plants, and geological materials. Dr. Leavitt has used the stable-isotope
composition (d13C and d18O) of
modern tree-ring chronologies from the Southwest, South America and PROFESSIONAL ACTIVITIES- Membership:
The Geochemical Society, American Geophysical Union, The Tree-Ring Society, American
Quaternary Association (executive council member), Ecological Society of
America Editor: Tree-Ring Research (2002-present);
Editorial Board: Radiocarbon;
Communicating Editor: Trees-Structure
and Function (2006-present) Ad Hoc manuscript peer review for 25 different journals &
proposal review for 10 agencies since 1994 SERVICE SUMMARY- Dr. Leavitt routinely
contributes to intramural service at the Department, College and University
levels through membership on several committees. Most notable among these was service on the
Provost's University Promotion and Tenure Committee (1996-99). Dr. Leavitt also served as Chairman of the
Global Change Interdisciplinary Program from which the Global Change Ph.D.
Minor is administered (1997-99). Dr.
Leavitt's outreach activities include general talks to service organizations,
and lecturing at a "Stable Isotope Ecology Course" held at the
University of Utah in June (1996-2010, except 2000 and 2006). CURRENT AND RECENT SUPPORT
