My collaboration with Dr. asadollahi, my supervisor, was not limited to my master’s research: After graduation, I continued to work with him as a research assistant. My work was mostly in the areas of synthetic biology, manipulating the key metabolic steps of the mevalonate (MVA) pathway and producing natural products by engineered microbes. I have been involved in two projects, dynamic control of gene expression in Saccharomyces cerevisiae engineered for the production of plant monterpen linalool and, heterologous production of kiwi linalool synthase gene in the yeast Saccharomyces cerevisiae. These projects involved using different techniques such as cloning, heterologous protein expression, metabolic engineering, and some biochemical methods. During these projects, I have learned many new techniques, which can be very useful in my future research.
