Video and Speaking
I am always looking for opportunities to share the wonders of science through multimedia.
For The New York Times, I have filmed more than a dozen Facebook Live science videos. Several of those videos were shot aboard a research vessel 100 miles off the coast of Maine. There, I documented marine scientists as they ventured to the seafloor in the Alvin submersible. I have also helped craft scripts for The New York Time's science video series, Science Take about brewing homemade explosive lava, and a cockroach's karate kick.
I also enjoy speaking with classrooms and groups of science enthusiasts. If you would like to have me virtually speak with your classroom or group, please send me an email at for more information.
