degree, Botany major,[1] and during the graduation ceremony she received the Gold Medal Award from King Bhumibol Adulyadej Rama IX.

In 1976 Kesara received a Fulbright grant from the US Embassy in Thailand for graduate study at the College of Liberal Arts and Sciences, University of Kansas.

[3] In 1988, after having worked for several years as a researcher in Iceland, Kesara began her PhD studies on plant cytology and genetics at the School of Biological Sciences, University of Cambridge, Churchill College.

Kesara received financial support for her PhD studies from the British Embassy in Reykjavík (the Chevening Scholarship), and the Overseas Fellowship from the UK Government.

Upon her departure from Thailand, Kesara was honoured with „The Most Exalted Order of the White Elephant, Companion (Fourth Class)“(จัตุรถาภรณ์ช้างเผือก), in appreciation of her academic service to the country.

[7] After Kesara completed her PhD in UK, she came back to work as a research scientist at this institute (1992 – 1996), focussing on the genetics of birch trees, while initiating her own study of lyme grass in Iceland.

[17] The first project in her PhD research was to use light- and electron microscopy to further support the model of higher order of nuclear organization in plants.

[28][29] Kesara has been developing a new cereal hybrid, namely “Triteymus” (Triticoleymus), which is derived from crosses between wheat (Triticum) and lyme grass (Leymus).

Firstly, the techniques were adopted for use in clinical cytogenetics, whereby whole-chromosome painting and gene localization were used to detect chromosome aberrations and disease-causing mutations.

Recently she has collaborated with researchers in other fields, such as ecology and archaeology, when it comes to using electron microscopy as a tool for imaging the microstructure of biological samples.

She has co-supervised a number of PhD research projects on Thai plants, including forest trees,[43][44] as well as medicinal and aromatic herbs.
