Dr. Christopher Topp is the principal investigator and associate member at the Donald Danforth Plant Science Center in St. Louis, Missouri. Topp runs a root biology lab where they develop techniques to study root systems both in the lab and in the field. They work with a number of novel imaging approaches to better understand root and soil biology beyond the current state of the art. Ultimately, he hopes this knowledge will be used for the benefit of farmers to improve the productivity and sustainability of agricultural systems. 

“The fundamental observation is that, we know so little about root systems…And this has real important impacts on plant health, plant productivity, soil health and our ability to meet the challenges of the modern day which are to at least not decrease the amount of soil we have and the quality of it, if not to actually regenerate it, but also to to feed a growing population under challenging conditions.” - Dr. Christopher Topp

Founded in 1998, the Donald Danforth Plant Science Center is a not-for-profit research institute with a mission to improve the human condition through plant science, research, education and outreach. They aim to have an impact at the nexus of food security and the environment.

“The mindset is to develop new technologies or bring them in from other areas and really learn how to apply them to roots. Once we do that, once we can see them or measure them in a meaningful way, then it's really every plant scientist's dream…Once we're able to get a good idea of what's the best kind of root system for a particular environment, we can then learn about mechanisms that allow us to breed or otherwise develop technologies that can improve root systems.” - Dr. Christopher Topp
