Research Interest
Natural product chemistry: isolation, structure determination, and Biochemical/Ecological application of natural products.

Education
Hajee Mohammad Danesh Science and Technology University, Bangladesh
M. S. 2007 (GPA 3.97 out of 4, First position)
Hajee Mohammad Danesh Science and Technology University, Bangladesh
B. Sc. Ag. (Hon’s) 2005 (GPA 3.55 out of 4)

Research Experience
I prepared organic extracts from plant samples for bioassay and isolation of compounds.  I did bioassay, such as germination, herbicidal, and insecticidal activities using the prepared plant extracts. I did chromatographic separation of bioactive plant extracts for isolation of active components. I also got a little experience of chemical structure determination by UV, IR, NMR, and MS spectrometry.
