Carnegiea gigantea


Conservation ecologist and PhD student

University of Arizona, Department of Ecology and Evolutionary Biology

Broadly interested in the application of computer modeling to conservation, I am motivated by the threats faced by our natural world and its inhabitants in the ongoing Sixth Extinction.

You can find my C.V. here.



More coming soon!

I am an avid collector of cacti and other succulents. By 2023, I hope to assemble a complete collection of all known cactus species, in order to conserve these plants ex situ. To do so, I need your help. If you have a lead on one of the missing species on this or list, please let me know! These are the IUCN Red Lists of critically endangered and endangered cacti, modified based on recent research and communication with cactus experts. See this article and its appendix for more information on the IUCN's cactus conservation classification efforts.


Driven by conservation? I'd love to hear from you!
