My research concerns crustal scale petrologic processes within island arcs. The focus is to understand the physical and chemical processes that operate within and beneath volcanic arc systems. What processes govern magma generation in the mantle wedge? What happens to these magmas as they traverse the Moho into arc crust? How does this arc crust become “continent-like”? This research takes the form of study of active arc systems as well as ancient systems. I am currently involved in three major research fronts: active Cascade volcanism, deep crustal sections of ancient volcanic arcs (Alaska, Vancouver Island, North Cascades Crystalline Core), and a marriage of the former fronts through a proposed research drilling expedition to the mid crust within the active Izu-Bonin volcanic arc of Japan.
In the Cascades, my students and I are interested in understanding the nature of the mantle input into the northernmost segment of the arc (the Garibaldi belt) and how that mantle input has been affected by crustal processes. This has taken the form of study of primitive mafic lavas from Glacier Peak and Mt. Baker (including H2O contents of melt inclusions in olivine), and the origin of more differentiated lavas from both volcanoes. I
In the arc crustal sections, my students and I have focused on the geochemical processing that occurs in the “crustal filter” after primitive magmas have crossed the Moho. To study this processing, we have focused on a paleo-Moho and lower crust transition zone from the Talkeenta arc in Alaska, the mid crust from the western Talkeetna arc and the Bonanza arc on Vancouver Island, and the deep crust of the Cascade Crystalline core.
In the Izu-Bonin arc, I am part of a multinational collaborative effort with the Integrated Ocean Drilling Program. The major goals of the project are to understand the origin of the Izu-Bonin arc from its inception, and to categorize the mid crust of the arc through analysis of drill cores. These observed samples can then be matched with remote geophysical observations, creating a blueprint for remote observations of other arc systems.

NSF has generously funded our North Cascades and Olympic Science Partnership as part of their Math Science Partnership Program. I am currently working with a group of community college faculty and WWU faculty to develop a year-long curriculum in introductory science for future elementary school teachers.
The earth science subgroup has developed a module-based, non-lecture course that is being readied for publication. You can read a bit more about it in an abstract for the 2008 Fall AGU DeBari et al., 2008 Please inquire if you are interested in field testing this curriculum.
Currently I am funded through a
Washington State Math Science Partnership (SPECK-8) to work with K-8 teachers
and administrators on enhancing and sustaining professional learning
communities in science.

I teach undergraduate major courses in petrology and volcanology, as well as upper-level undergraduate/graduate courses in Igneous Petrology and Geochemistry. In addition to the normal classroom version of petrology (for majors), I also teach a field version (pre-fall petrology) where we integrate theory and practice at the outcrop.
