I am planning to cover some of the topics that I was focused during my career in the field of Bacillus thuringiensis: 1. Discovery of new Bt insecticidal proteins. 2. Structure and mode of action of Cry2A. 3. Mode of action of other Cry Proteins. 3. Engineering Cry proteins for improved insect control, by different technologies such as Domain Swapping, Supporting Technologies, DNA Shuffling, Saturation Mutagenesis. 4. Bacillus subtilis Spore Display.
