His specialty is geology/geophysics (his business card says “environmental geophysics”), with a concentration in paleomagnetism. He is particularly interested these days in the environmental applications of rock magnetism. He mostly teaches intro physics, but would some day like to teach geoscience courses again. He is married to Bonnie Becker; they have a one year old son (pictured, with fish) and a giant dog. He hates talking about himself in the third person.
