Natascha Techen

Principal Scientist

Natascha Techen

Dr. Techen’s interest is in the development of molecular (DNA) markers that can help with the identification of medicinal plants of raw drugs or present in dietary supplements.

Research Interests

  • Extraction of genomic DNA from fresh or processed plant material
  • Identification of genomic regions helpful for identification (DNA barcoding)

Biography

A native of Hamburg, Germany, Dr. Natascha Techen received her BS, MS and Ph.D. in Plant Molecular Biology at the University of Hamburg, Germany.

Dr. Natascha Techen joined the Natural Center for Natural Products Research at the University of Mississippi in 2002. She is working in Dr. Ihklas A. Khan’s team on the identification of genomic markers, also known as ‘DNA-barcoding’, that can help with the authentication of plant material/dietary supplements and its adulterations by using various molecular methods. In addition, her research has helped with the genetic improvement of crops, medicinal or ornamental plants for higher yield and nutrient value, disease and pest tolerance, non-invasiveness, and ornamental traits. She is currently working on the development of DNA mini-barcodes (<250 bp) to help with identification using fragmented DNA present in processed plant material.
