Name: Djaja Djendoel Soejarto
Position/Title: Research Associate
Department: Botany

1. What do you study related to biodiversity (what are your research questions, what organisms do you work on)?



Taxonomic inventory of Angiosperms diversity at Cuc Phuong National Park, Vietnam.
Cataloguing plants of Laos used in disease treatments, with special reference to CNS-related diseases and infectious diseases
Potential value of plants of Cuc Phuong National Park as a source of drugs to treat cancer, malaria, AIDS, tuberculosis
Improving strategies in the protection of biodiversity of Cuc Phuong National Park
Preserving the knowledge of indigenous communities who live around the Cuc Phuong National Park on the uses of plant of the park in the treatment of diseases

2. How do you study biodiversity (for example, what technological tools and methodologies do you use in your research)?



I use conventional field botanical explorations, collections, herbarium documentation, museum repository, taxonomic identification. I also prepare documented Checklists as a book and post database on the Internet. In addition, I am preparing a manual for taxonomic identification.

I collect plant samples documented by herbarium specimens and extract samples, bioassay of extracts in selected disease systems, bioassay-guided fractionation and isolation of active compounds, structure elucidation of active compounds.

Assessment of mini-hotspots, change detection of vegetation cover, ground-truth to provide support of the hotspot concept, establish sites for living gene banks of threatened plants (Threatened Plants Rescue Center), and plants with potential commercial importance (f.e. Aroids, orchids), conservation education

Field ethnobotanical interviews, herbarium documentation, database building, establishment of ethnomedical garden, compilation of books on medicinal plant use

Publishing results in scientific journals

3. Where do you study biodiversity?



Vietnam and Laos

4. How might your research have implications for biological conservation?



To promote and strengthen awareness among communities in the protection of the biodiversity
To strengthen capacity in the protection and sustainable utilization of biodiversity
To promote interest and action of scientists in the further study of the biodiversity

5. How did you become interested in science? What made you want to be a scientist, and how did you get to The Field Museum?



An opportunity to contribute in the pursuit of new knowledge and be a useful citizen.

6. Describe important collaborations for your scientific endeavors (describe your work with other researchers, organizations, or scientific groups, local or indigenous peoples, etc.)



The activities described above are implemented with the cooperation of many scientists in various countries, primarily:
Program for Collaborative Research in the Pharmaceutical Sciences, College of Pharmacy, University of Illinois at Chicago, Chicago, USA
National Center for Science and Technology, Hanoi, Vietnam:
Institute of Biotechnology
Institute of Chemistry
Institute of Ecology and Biological Resources
Cuc Phuong National Park, Ninh Binh, Vietnam
