I am an associate professor at the University of Cincinnati in the Department of Geology specializing in Precambrian Paleobiology, Astrobiology, and Biogeochemistry. I focus on the origin and evolution of the earliest life on Earth, namely bacteria, cyanobacteria, archaea, and their distant relatives (see my Research page). I also focus on searching for life elsewhere in the Solar System and am a science team member of NASA's upcoming Mars 2020 mission.
**Ph.D. student needed for NASA-funded project!**
I am searching for a Ph.D. student to join my lab at the University of Cincinnati in August 2021 on a fully-funded NASA Exobiology project titled “Oxidizing Oases in the Paleoarchean Moodies Group, Barberton Greenstone Belt, South Africa”. The student would join an international team to study the environmental distributions of early oxidizing photosynthetic communities and associated weathering processes through a cross-disciplinary approach.
The planned Ph.D. project will be based largely on multiple stable isotope geochemistry (C, O, and Fe) and Raman spectroscopy of organic materials associated with detrital minerals. Experience with geochemistry (particularly isotope geochemistry) is preferred, but not required.

**MARS 2020 MISSION UPDATES**
NASA is sending the Perseverance rover to Mars to explore Jezero crater and search for evidence of ancient life. The rover launched successfully (beautifully!) from Cape Canaveral on July 30 at 7:50 am EDT (click here to re-watch) and will arrive at the Red Planet on February 18, 2021.
Perseverance is doing great and is en route and on schedule! Click here to see a visualization of the current location of Perseverance.
Follow along here for updates or at NASA's Mars 2020 mission website.
See links to interviews I have done about my involvement in the mission in Czaja Lab In The News (on the right).

UC and several local media outlets have featured my involvement on NASA's Mars 2020 mission and the upcoming launch on July 30, 2020.

WCPO Cincy Lifestyle (video)
UC and Outside Magazine featured Andrew Gangidine and his work developing a trace element biosignature that could be applied to the search for life on Mars. We were also interviewed by WCPO ABC 9 for their Cincy Lifestyle program.

UC featured my work with the Mars 2020 mission as a member of the Returned Sample Science Board and Landing Site Working Group. Subsequently Andrew Gangidine and I were interviewed on Cincinnati Edition on 91.7 FM WVXU.
