Happy Halloween from the Morran Lab!

A very successful 2nd annual pumpkin carving party for the lab!



Community Outreach

The Morran Lab visits Morrow Elementary School in Morrow, GA to demonstrate how C. elegans avoid pathogens- without vision capabilities! The students had a blast using their noses to locate the yummy food (chocolate chip cookies) and avoid the yucky food (rotten eggs)!

The students also had the opportunity to use the microscopes and identify different C. elegans lifestages.

Graduating with Highest Honors

Congratulations to Morran Lab undergraduates Will Milligan and Jae Hoon Cho for successfully defending their Honor’s Theses and graduating with Highest Honors!


Jae Hoon’s thesis is entitled, “Parasite virulence and the maintenance of outcrossing in the Caenorhabditis elegans and Serratia marcescens system”
Jae Hoon is heading to Amherst College as a research technician for Dr. Michael Hood.

Will and Levi Graduate 2017
Will and Levi, College of Arts and Sciences Graduation, Emory University, May 2017

Will’s thesis is entitled, “An empirical test of Baker’s Law”
Will is off to Columbia University as a grad student in the JD/PhD program in Biological Sciences.

New Publication for Postdoc Mandy Gibson

Mandy Gibson just had a paper published in Evolution Letters – it’s the first accepted paper in the first issue of this brand new journal! Evolution Letters is a joint journal between the US and European evolutionary biology societies and is supposed to fill in the gap in impact factor between the current of evolutionary biology journals, i.e. Evolution, and really big journals like Science

“The two-fold cost of sex: experimental evidence from a natural system” 2017 Evol Letters 1(1): 6-15.

“Theory by Maynard Smith in the 70’s proposed the two-fold cost of males as the primary cost of sex in dioecious species (species with separate males and females). Here, we experimentally validate this theory. In the snail Potamopyrgus antipodarum, there is indeed a two-fold cost of sex.”

You can find the open-access article here, plus commentary on the Evolution Letters blog.

Morran Lab in Action!

 Morran lab team members are always happy to strike a very science-y pose!
