Curriculum Vitae

Early Earth Photosynthesis working group
The Macalady Geomicrobiology Lab is housed in the top-ranked Department of Geosciences at Penn State University.

Members of the Macalady group are interested in two fundamental questions at the interface between geosciences and biosciences:
What are the ecological rules that govern microbial behavior and evolution?

What can modern Earth microorganisms teach us about the biogeochemistry of the early Earth and signatures of life on other planets?
Join the Macalady group/find research funding

"My mitochondria comprise a very large proportion of me...I suppose there is almost as much of them in sheer dry bulk as there is the rest of me. Looked at in this way, I could be taken for a very large, motile colony of respiring bacteria, operating a complex system of nuclei, microtubules, and neurons for the pleasure and sustenance of their families, and running, at the moment, a typewriter."

----Lewis Thomas, The Lives of a Cell, 1974
