The Pakrasi Lab studies how cyanobacteria use solar energy to drive the chemistry of life.

We work in many disciplines and have projects that focus on determining how the molecular machines that capture solar energy are assembled and maintained, how cyanobacteria respond to environmental changes at the systems level, and how to engineer new strains of cyanobacteria that are capable of channeling solar energy into biochemical production.

We are part of the Department of Biology at Washington University in St. Louis.
