Investigating explosive eruption dynamics with field, laboratory, and numerical methods
Through the lens of geophysics and fluid mechanics, my research spans volcanology, glaciology, landslides, wildfire plumes, and planetary science.

My research explained with the 10,000 most common words
The #UPGOERFIVE challenge asks scientists to explain their work using only the 10,000 most common English words. Here's mine:
Hot stuff!
In a safe space at school, I study how hot and heavy groups of air, water, and
rocks (stuff) come out of the ground really fast, play with each other, and eats
cold air to try and fly into lighter air way above the ground. If the hot stuff
doesn't have many rocks, moves fast, and eats a lot of cold air, it will go up
and stay up where it can change the air around the world and break flying buses
of people. If the hot stuff has a lot of rocks, moves slow, and does not eat a
lot of cold air, it will go up and come down where it can run people over on the
ground. What do you need to know? Stay away from hot stuff coming out of the
ground really fast!
