Continental flood basalts, ocean ridges, hot spots
interests range from the origin of the mantle and crust,
hot spots, and continental flood basalts. My graduate
students, post-docs, and I use a variety of tools that
range from experimentally melting rocks in the laboratory
to isotope and trace element geochemistry. I have two
long-term projects - one on Hawaii and the other is
on the Deccan Traps (India). Of late, I have become
interested in the Columbia River Basalts (NW USA).
terms of instrumentation we use high-pressure piston-cylinder
and 1 atmosphere furnace, electron microprobe (at FCAEM),
ion probe (at the Woods Hole/MIT facility, ICP-MS and
mass spectrometers (at Vincent Salter's Lab at Florida
the moment, I have 4 graduate students: Andy Acosta
(MS, expected Dec '07), Melroy Borges (Ph.D., Dec'07),
Kevin Chau (MS, Summer'08), and Indra Sen (Spring'09).
My recent ex-students are Shantanu Keshav (Ph.D. '03,
presently at Bayreuth), Sedelia Durand (Ph.D.'06, presently
at Lamont-Doherty Earth Observatory, Columbia University),
Zachary Atlas (MS'02, Ph.D. candidate at Univ. Miami),
Susan Schulz (BS'02; finished Ph.D. at ASU), Kevin Chau
(BS'06, MS student). My post-doctoral fellows were Michael
Bizimis (FSU), Mihai Ducea (UArizona), Huai-Jen Yang
(NCKU, Taiwan). Tobi Cohen was my first BS and MS ('89)
