HOW TO APPLY

Blurb:

Sophie is a curious and committed PhD student using tree rings to uncover clues about past earthquakes, particularly along New Zealand鈥檚 Alpine Fault.听Her research sits in the wonderfully niche world of dendroseismology, where tree-ring growth anomalies help piece together the timing of prehistoric quakes. Sophie's motivated by a love of learning, a collaborative spirit, and an unshakable (pun intended) sense of fairness.

Before swapping paddles for p-values, Sophie spent years chasing summers as a rafting guide across Aotearoa, the USA, Canada, and Japan. Life on the river sharpened her appreciation for the natural world, and her talent for explaining complex things while soaked, sunburnt, and halfway down a rapid. Now mostly dry and usually examining tree-cores, Sophie enjoys sharing her knowledge and enthusiasm with anyone who's even mildly interested (and sometimes those who aren't).

Also worth knowing: Sophie is rarely far from a snack. Whether it's tree-ring data or dark chocolate, she believes good things are better when shared, so if you're ever caught hungry on campus, her office is a reliable place to refuel.
