Current Research Research is underway! Andrea's research involves the investigation of variables that influence the preservation and successful recovery of DNA from archaelogical and forensic samples. Variables such as elemental composition, oxidation/reduction potential, and pH of the burial environment, time since death, macroscopic and microscopic condition of the specimen, and exposure to UV radiation are being explored, through experimentation on modern DNA as well as analysis of soil/sediment and biological samples from the Silvernale Village site in Red Wing, Minnesota and from the Kromdraai, Wonderwerk Cave, and Border Cave sites in South Africa. |
