On 19 November 2019, Web of Science (WoS) – Clarivate Analytics (USA) published a list of Highly Cited Researchers (HCR) around the world. Prof. Bui Tien Dieu, Head of the Geographical Information Science Research Group of Ton Duc Thang University (TDTU), was listed among 6,216 researchers with leading scientific citations in all fields. This year, Vietnam has only two scientists having this honor including Prof. Dieu and another expert in the field of computer science.

Prof. Bui Tien Dieu, an Overseas Vietnamese expert in Norway on geoinformatics, has published 171 research works in prestigious ISI journals, with an H-index of 34 and a cited index of 3,840.

Scientists who have high citations under WoS are those whose publications have been cited in the top 1% of the field. This index reflects the influence of the research results among experts of the field. Compared to the top 100,000 scientists highly cited according to PLOS Biology (based on Scopus), HCR is a greater honor because:

• WoS is based only on 16,830 world’s best journals while Scopus is up to 24,701 journals; in addition to ISI journals (all under Scopus), this database consequently has many other non-high-level journals.
• HCR only selects 6,216 strongest scientists, while PLOS Biology selects 100,000 people.

In recent years, TDTU has promoted the Government’s Overseas Vietnamese policy well. Many famous Overseas Vietnamese scientists in the world have had effective research, teaching and consultancy programs at TDTU. Apart from Prof. Dieu, there are many other famous Overseas Vietnamese scientists such as Prof. Nguyen Van Tuan (Australia), Prof. Nguyen Minh Tho (Belgium), Dr. Tran Phan Lam Son (Japan), Prof. Le Khanh Chau (Germany), Prof. Dinh The Luc and Prof. Phan Thien Nhan (Singapore),…are working and collaborating effectively at TDTU.
