Kaitlyn Eldredge

My name is Kaitlyn Eldredge, I am originally from Boise, Idaho. I am a historical archaeologist with experience in 19th century U.S. military forts and various 20th century settings in the American West. I have come to NCPTT as the Research Associate working on the Fire Suppressants and Cultural Resources Project. I will be researching how chemical fire suppressants interact with cultural material types used in precontact and historic architecture. Additionally, I will be identifying the most effective methods for removing fire suppressants from these cultural materials. The results of this research will provide managers of cultural resources and wildland fire an understanding of the application and remediation of fire suppressants.

I am very excited to be a part of this research, as coming from Idaho I am no stranger to wildfire. I’m a recent graduate of the University of Idaho’s graduate program in Anthropology. While there I combined my passion for archaeology and my interest in wildland fire. I used experimental archaeology to study the effects of mechanical fireline construction and rehabilitation on archaeological sites. I look forward to expanding the knowledge of the ways in which wildland fire management activities impact our Nation’s heritage.]

Isabella Jones

Hello there! My name is Isabella Jones and I am a Fall 2019 graduate of Northwestern State University. At NSU I earned a bachelor’s degree in biology with a concentration in natural sciences as well as a bachelor’s degree in art with a concentration in graphic communications. I have always been interested in wildlife as well as art, so I chose to pursue education in both fields. My biology degree has allowed me to learn a vast amount about animal physiology, animal species identification, coordinating and maintaining species management plans, and many other areas of interest. At the same time, the art program allowed me to be creative and develop my skills in both the fine arts as well as the graphic design medium.

My time here at the National Center for Preservation Technology and Training is spent on a variety of projects but my main focus is videography. I able to film various topics such as oral histories, fellow researchers explaining their projects, and an important series where we are documenting and explaining the equipment available at NCPTT. These videos can be found here on NCPTT’s website or on our corresponding YouTube page. My next big task here will include joining the Preserving Tenant Cabins Project. Our team will scan and document various tenant cabins across the nation. It is something I very much look forward to being a part of.

Through the process of recording and editing, I am able to learn a broad range of topics and skills. Being able to document and listen to personal accounts of the past has given me world knowledge I did not have before, such as Mr. Tommy Whitehead’s personal stories of Clementine Hunter, Mr. Elvin Shield’s recollection of his time living and working on a plantation, to each instrument video where research is conducted, and an explanation to such is provided. My skills have not stopped developing after graduating college; instead, my role here at NCPTT continues to encourage me to learn more, be more creative, and push what I thought were the limits because I am being shown that everything is limitless.

Abigail Poe

Hello! My name is Abigail Poe, and I am from Natchitoches, LA. I attend Northwestern State University where I will be graduating summa cum laude this spring as a biology major with a concentration in biomedical sciences and minors in chemistry and Spanish. From performing experiments as a child to researching what makes the things around us tick, I have always been passionate about this field, so I wanted to continue studying it as an undergrad. At my university, I have been able share this interest with others as a teaching assistant for general biology and chemistry classes and as president of TriBeta Biology Honor Society by bringing in speakers and hosting workshops. I have also participated in undergraduate research through my department as well as a fellowship at LSUHSC in Shreveport, LA.

Last August, I began working at NCPTT as a materials conservation research intern. My project focuses on characterizing the effects of herbicides on historic stone and masonry materials. An earlier project here by Caitlin Oshida showed the destructive effects of using glyphosate-based herbicides, so I am investigating how alternative solutions impact these materials. These results will be used to develop recommendations for managing weeds and other vegetation without causing damage to surrounding historic features.

This internship has given me the opportunity to learn new lab skills like cutting samples with a power saw and using analytical instruments like the FTIR to analyze them. I have truly enjoyed learning about historic preservation, from the hands-on experience through my research as well as talking to other researchers and staff here who have shown me their work. I am grateful for this opportunity to be involved with this project and look forward to sharing the findings of it with y’all in the future!
