The National Center for Preservation Technology and Training announces 2019 internships, pending the availability of funding. We have opportunities for paid internships. We just need you! Projects are available working across disciplines. Interns will have an opportunity to work in one of the following programs:

  • Architecture and Engineering
  • Archeology and Collections
  • Historic Landscapes
  • Materials Conservation

Most of the projects are six-month full-time internships unless noted otherwise.
Internship opportunities are available for the following projects:

Historic Landscapes

Alternative Weed Control in Historic Landscapes.

Female student outdoors near a historic buick building. She is applying Roundup herbicide to weeds.

Herbicides are tested to determine possible effects to building materials.

One-Year Term with option to renew. Estimated Start Date August 15, 2019.

Herbicides are widely used, both locally and internationally, on all types of cultural heritage. They have become an integral part of vegetation management in the conservation of heritage. Glyphosate is the active ingredient of the world’s most used herbicide-products, the most common of which is known with the trade name Roundup™, manufactured by Monsanto. However, this product is suspected of causing damage to humans, the environment, and cultural resources.

The research associate will evaluate the relative efficacy of alternative weed control methods for use on common weeds, and determine the effects of alternative weed control methods on common building materials.

Materials Conservation

Treatments for Oiled Historic Properties.

Six Months, July 15, 2019 to January 15, 2020.

As we see more and diverse oils being moved by pipeline, rail, ship, and truck, the chances that different historic materials will be oiled increases, yet we know very little about what products and techniques are effective at removing a given oil from a given historic material. This research will inform the treatment of cultural heritage that has been exposed to oil.

The Research Associate will conduct phase two of an ongoing study. The Research Associate will test surface washing agents on oiled historic building materials, analyze data, and maintain research equipment at NCPTT. Duties include preparing, treating, and artificially weathering samples, and evaluating results using various scientific instruments. The person may assist in the development of the experimental design and/or write up the results for publication.

Fire Suppression on Cultural Resources.

Firefighters use various fire suppressants to combat fires.

One-Year Term with option to renew. Estimated Start Date August 15, 2019.

According to the National Interagency Fire Center, wildland fires from 2007 to 2017 affected more than 75 million acres of land. Wildfires pose a threat to cultural resources including both known and undiscovered historical structures and archeological sites. A new generation of chemical fire retardants and suppressants have come into use over the course of the last decade.

The Research Associate will study the effects of fire suppressants on cultural resources, and identify methods to remove fire suppressants from cultural resources.

Anti-graffiti Coatings on Corten Steel.

This is a ten-week internship. Estimated Start Date is flexible.

Graffiti materials such as aerosol spray paint and Sharpie marker easily penetrate the distinctive patina of weathering steel, which is more porous and rougher in profile than that of other metals commonly used in outdoor art and architecture such as stainless steel, copper alloys, or aluminum.

The Intern will conduct an investigation into anti-graffiti coatings for outdoor weathering steel. The proposed investigation will aim to explore the possibility of coatings as a solution to the multifaceted problem of graffiti removal from weathering steel, taking into account aesthetic and material considerations regarding the use of coatings on weathering steel for graffiti removal purposes.


Applicants should demonstrate skills and knowledge in preservation technology. This may include but not be limited to documentation, condition assessments, literature reviews, laboratory or field research, materials testing, hands-on preservation treatments, or other related skills. Undergraduates, graduate students, or recent graduates will be considered. Studies in in disciplines such as architecture, anthropology, conservation, chemistry, engineering, geology, geography, preservation, etc. will be preferred.

We encourage applicants to contact Mary Striegel (, phone: 318-356-7444) at NCPTT to discuss the details of this internship.

How long are the internships?
Most internships last six months unless otherwise noted, beginning and ending dates are negotiable. Please note your available dates for the internship.

Will I get paid?
Yes. Our interns are short-term employees of Northwestern State University. Compensation is based on experience, including academic experience. Depending on your personal spending habits, the compensation provided is typically more than sufficient to cover living expenses during your stay in Natchitoches.

Is housing provided?
Housing is not provided. However, Natchitoches is a college town and there are usually plenty of sublets and short-term rentals available.
