Chemistry & Engineering News selected Will Tarpeh (CE PhD _) as one of its "Talented 12:  Young scientists tackling the world's problems with chemistry."

Tarpeh is developing ways to extract resources from human waste, such as nitrogen in urine, to make valuable products, like fertilizers and cleaning products.

"This idea of looking at waste as a resource could help us meet the environmental challenges of a growing human population and changing climate," he says.

Tarpeh is current an Assistant Professor at Stanford University.
