This fellowship is awarded to outstanding candidates from each of the 10 Asian countries.

Her research in microbes producing novel enzymes is very productive for her, boasting an extensive output of research products in a relatively short period of time. This is highlighted by her current h index of 29 with 2649 citations (up to August 2015) with 211 publications in in refereed journals, most of which are in renowned international journals. Numerous other papers were presented at conferences and seminars held locally and overseas. Further to that, she contributed to a number of book chapters including one in ‘Trend in Biotechnology Research’ published by Nova Science Publishers, Inc. New York. The same publisher invited her to write a book on her specialised area entitle ‘New Lipases and Proteases’ and this book has been in international circulations since 2006. Her second book from the same publisher, “Molecular and Structural Biology of New Lipases and Proteases” is now available since July 2013.
