What he does
Jim studies how lava flows move and how lava tubes form by watching and measuring them as they erupt. He examines Hawaiian volcanoes, measuring how dense they are, how they're magnetized, and how well they conduct electricity, to figure out how they're built.

How he got into science
Jim always liked being outdoors, finding as many different kinds of rocks, birds and seashells as he could. Curious about their stories, he got into science. He was all set to be an oceanographer…until he took his first geology course.

Favorite accomplishment
Jim found a way to measure how fast liquid lava can re-melt the cooled, hardened lava that it's flowing over.

In his free time
Jim still loves the outdoors. He hikes and swims, and sings with choral groups, including one that sings Hawaiian music.
