PhotosynQ is a platform allowing people to collaboratively solve difficult research questions, both at the locally and globally, using sensors which connect to your cell phone. The MultispeQ, our first sensor, measures important parameters of photosynthesis in plants and algae in a non-destructive way, quickly and inexpensively. These measurements provide a detailed picture of the health of the plant and are used for plant breeding, agricultural extension services, and plant scientists to improving plant efficiency and to identify novel photosynthetic pathways for energy and crop research. Anyone can propose a project on the PhotosynQ website (www.photosynq.org), and anyone else can contribute data, ideas, analysis, and discussion to that project. There are researchers and citizen scientists around the world already running projects through PhotosynQ which you can contribute to. Once you join the platform, find an open project and contact the project lead to join, or design your own project!
