Marcell D. Cadney, PhD

Profile picture of Marcell

Hello and welcome 👋. I am an evolutionary biologist interested in the intersection of evolution, epigenetics, and physiology. I am currently in the University of California President's Postdoctoral Fellowship Program (UC PPFP) at UC Santa Barbara, where I am working on a number of projects.

I am specifically interested in studying the epigenetic components involved in early-life effects, the development of complex traits, how those components evolve, and how they might affect the evolution of complex traits. I employ a number of experimental approaches centered on evolutionary physiology in mice to help address these topics.

I am also interested in the evolution of the human brain and have taken a comparative approach in that respect.

Finally, future projects may take the form of "assisted evolution," where selective breeding (i.e., my PhD work), epigenetic programming (i.e., my Postdoc work), and microbiome transplants (again, my PhD work) can be used to rehabilitate threatened and endangered species in the face of accelerating climate change.

As a hobby, I make 3D models in Blender. Sometimes I even finish a project! Check it out!
