Biography

Ismail B. Sahid was born on 5 October 1951 in Penang, Malaysia. He received his secondary education from SMK Panglima Bukit Gantang, Perak, Malaysia. After that he was enrolled at Kolej Islam Malaya, Petaling Jaya, Selangor, Malaysia (1969-1970). He received a BSc in Biology from Universiti Kebangsaan Malaysia (UKM) in 1975 and PhD (Botany) in 1978 from University of Sheffield, United Kingdom.
Then, he joined UKM as a lecturer and appointed as Assoc. Professor in 1984. In 1993, he was appointed as a Professor. His researches of specialization are, Weed Biology/Management, Allelopathy and Environmental Toxicology.
He was awarded research grants from the Ministry of Science, Technology and Innovation, Malaysia (MOSTI) to study the impact of pesticide application in Malaysian agroecosystem. He also received a research grant from MONSANTO (2000-2006) to study the resistance of Eleusine indica toward glyphosate (Roundup®) and from the International Rice Research Institute (IRRI) in 2006-2008 to study the level of pesticide contamination in the MADA rice fields in Kedah, Malaysia. Recently, he received research grant from MOSTI. The study is to predict the pollution of pesticide using SWAT model. To date, he has written more than 300 articles in international journals not included a number of papers presented during the national and international conferences. He has supervised 40 PhD and 60 MSc students.
Prof. Ismail has received few awards such the most prolific author from UKM in 2003. The author also had received award on the best articles from Malaysian Palm Oil Board for two consecutive year 2003 and 2004 for discovering new and effective method for the detection of pesticide compounds in palm oil.
