CURRENT GRADUATE STUDENTS

J is investigating the ecological and evolutionary consequences of environmental change on Cretaceous and Cenozoic decapod and ostracod crustaceans.
Keenan is studying the response of coralline algae to environmental change over the Cenozoic.

PROSPECTIVE GRADUATE STUDENTS

Unfortunately, I won't be able to admit new students during the 2023/24 application cycle unless you have external funding. I'm happy to work with you on applications for fellowships, such as the NSF Graduate Research Fellowship. Please contact me to discuss ideas if you are interested. 


In general, I'm interested in mass extinctions, the role of physiological and ecological traits during ancient rapid climate change, long-term macroecological shifts, and fossil cephalopods. I also help students to pursue other interests in addition to research, including pedagogy/education, mentoring, projects to support diversity and inclusion, or outreach and science communication. For more details about my mentoring goals and about what I look for in an application, read here.
