Career

I have a PhD in plant systematics from Uppsala University, and since 2012 I have been a research fellow at Naturalis on a Dutch Science Council grant.

Research

Research interest

My research focuses on different aspects of plant use and identification, and ranges from molecular identification to genomic barcoding, plant systematics to biogeography, and women's health to market ethnobotany.

Keywords

molecular identification, medicinal plants, orchidaceae, dna barcoding, wildlife trade, cucurbitaceae, plant systematics, traditional medicine and women's health, ethnobotany

Current research topics

Identifying and monitoring trade in Tanzanian wild-harvested medicinal plants by means of innovative genomics-based DNA barcoding

In Tanzania, medicinal plants are used as a primary source of healthcare by many people. However, commercial trade in these medicines has made Tanzania's main sources of medicinally-used plants into some of the most threatened biodiversity hotspots in Africa.

Our research project aims to stimulate the creation of a system of exploitation that is controlled and sustainable by investigating current trade. The main objectives of the program are to conduct a quantitative investigation of traditional herbal medicines traded in Tanzania and to identify diversity and volumes of medicinal plants traded in Tanzania.

As most material is traded in dried, shredded or powdered form, making it difficult to identify, we use next generation sequencing techniques. This allows for the identification up to species level of processed material that has hitherto been impossible to identify. In addition, surveys to monitor the chain of commercialization give insights into the processing, collection, identification and availability of plant species traded. This will allow for matching of identified wild-collected plants with the specific parts used in medicine, such as the roots, barks and wood, before these are further processed for retail sale.

 

Harvesting traditional medicinal plants, Tanzania.

Collaborations

This project is funded by the collaborative TASENE program, an initiative by NWO Netherlands, SIDA Sweden and COSTECH Tanzania.

The project is a collaboration with Dr. Joseph Otieno, Institute for Traditional Medicine, Muhimbili University of Health and Allied Sciences, Dar es Salaam, Tanzania, Dr. Barbara Gravendeel and Dr. Tinde van Andel, both at the Naturalis Biodiversity Center, Leiden, The Netherlands, and Dr. Ted Mselle, Department of Biochemistry, Muhimbili University of Health and Allied Sciences, Dar es Salaam, Tanzania. Sarina Veldman (Uppsala University) works as PhD student within the project.
