My lab focuses on photosynthesis for improved crop production, though I am very interested in the biology of photosynthesis. I also try to address questions involving the climate change, sustainable agriculture, and smart agriculture. My dream is to make a crop management system where plants optimize their growth environment (e.g. water, light, nutrients) by themselves to maximize their production at a given amount of resources. I like purpose-motivated and interest-driven science!
