Gideon V. Long
Astrobiology and Evolution
Hello! I am a researcher at the University of Arkansas currently working on my doctorate in the lab of Dr. Timothy Kral. I have a focus in astrobiology, and investigating the possibility of methanogens living on Mars.
My Research
Mars is the epitome of an extreme environment. Excessively cold temperatures of -80ºC, low pressure, few nutrients, and the surface is under constant bombardment by UVC radiation. While it is a difficult place to live, saying there isn't a possibility of life does evolution a great disservice. Methane exists within the Martian atmosphere, and had if it wasn't being replenished, would've been destroyed by UV radiation. While the methane could have abiotic sources, it might be possible that something similar to methanogenic archaea could be the source, as most of the methane here on Earth is from methanogens.
Current Projects
My current investigations involve seeing if methanogens can survive temperatures similar to Mars with the addition of salts present on mars, like magnesium perchlorate. My other project is seeing the length of time that my organisms can survive UVC light. The follow up to this is whether or not these organisms can develop a resistance to UVC.
