Graduate Students

     Masters student Elizabeth Harris' research focuses primarily on an analysis of the subsurface processes occurring in the 392 Coastwide Reference Monitoring System (CRMS) sites. An examination of the CRMS sites will provide insight into how these processes impact wetland elevation. In addition, this knowledge may be applicable to marsh resiliency in Louisiana amidst relative sea-level rise.

     Masters student Derek Jacobs is interested in better understanding the Roseau cane die-back, and the implications for vegetation restoration, through an intensive field survey and a corresponding greenhouse study.


 
 

Postdoctoral Researchers

     Lab associate Alex McClellan, PhD, worked closely with the Quirk Lab while completing his dissertation research, which focused on organic matter development in coastal wetland soils and how its composition may be impacted by different wetland restoration strategies. He is currently studying the impacts of climate-related factors on marine cyanobacteria for his post-doctoral research under Dr. Edward Laws.

     Austin Lynn (PhD, University of Missouri) is studying abiotic stressors implicated in Phragmites australis dieback, and how these change with different flooding levels and across haplotypes. He is also researching ecosystem services of alternative wetland plants for consideration in marsh restoration.


Technicians and Undergraduate Researchers

     Catherine Bruns is conducting a seed bank assay on Phragmites australis, which is beneficial to coastal Louisiana areas because it stabilizes the edges of navigation channels, limits erosion, and facilitates high accretion rates. Her project will determine how seed bank compositions and densities vary among stands with different haplotypes of P. australis.

     Olivia Hurley is working to understand Phragmites sexual reproductive effort in terms of seed and pollen production in dieback sites compared to healthy sites.

 Cian Butler graduated in May 2021 with her B.S. in Microbiology. She is the lab and field technician, and helps out with little bit of everything. Cian is currently working on Phragmites research.
