Full-Time Close All Job Summary

The Kralj lab is looking for a postdoctoral researcher to develop new molecular and hardware tools for optogenetics. The project will involve working with diverse cellular systems including bacteria, yeast, and neurons. We are interested in controlling the flow of ions across specific cellular membranes to enable precise perturbations in space and time with which to identify downstream physiology. The Kralj lab leverages high-throughput, single cell imaging to develop new optical sensors and actuators, and then combines those tools with advanced analytics to discover new biological insight at large scale. We are also interested in new potential directions and are excited to integrate new skills into our existing pipelines.

Who We Are

The Kralj lab is located in the BioFrontiers Institute and Molecular, Cellular, Developmental Biology departments at CU-Boulder. The lab is housed in a state of the art building which houses BioFrontiers, Biochemistry, and Chemical and Biological Engineering, which fosters an interdisciplinary and collaborative environment.

What Your Key Responsibilities Will Be

The postdoc will be expected to lead a project to develop new optogenetic actuators and associated optical hardware. This will include creating new protein constructs, high throughput functional imaging protocols, and data analysis pipelines. The candidate will take the lead writing scientific articles and presenting data at conferences. The postdoc will also be expected to help other members in the lab as appropriate. The postdoc will report directly to Dr. Kralj.

What You Should Know

The Kralj lab is a fast paced scientific environment and candidates will be willing to adapt the project as data is collected. Travel will be expected to scientific conferences.

What We Can Offer

Salary commensurate with experience.
