Sam Herreid, Ph.D.

I am an Alaska-raised, Europe-educated, and now California-based glaciologist. I work in the Rignot Research Group at the University of California Irvine and specialize in SAR interferometry. I am currently working with data from the recently launched NASA-ISRO NISAR mission to produce continent-wide maps of ice sheet velocity in Antarctica.

I also work on debris-covered mountain glaciers, both in the field and with satellite data. My field program is based in the Eastern Alaska Range and I have expertise using both satellite and field-based thermal data for glaciology applications.

Running

Running

I am an Alaska-raised long distance trail runner who let a science PhD and a few postdocs dictate some less than ideal locations for a trail runner to live. While I’ve done some formal racing (resume below), a majority of my running has been adventure running and urban ultras (see Instagram story archive). I have published some writing about running. Mostly comedy and a little bit of fiction (links below). I’ve also quietly written and recorded an album about running. It was supposed to be the Beach Boys of trail running, “Catch a ridge and you’ll be runnin’ on top of the world” sort of thing, but instead it became more nuanced and character sketch-y, maybe even subtly political. I don’t think anyone has taken the time to actually listen to it, maybe you’ll be the first. (I’ve tracked out the recording for some of the songs, but I thought it would be fun to record the album straight through, playing every instrument, with a live studio audience. Let’s go.)

Music

Music

Before the running and the black hat and the science, there was music. In high school my friends were buying cars and I bought a piano. Most recently I wrote and filmed a straight playthrough of an album I wrote in New Jersey about running (below). It was on a beautiful Young Chang baby grand that I had to sell to move to California. I’ll probably buy a new one soon…
