Welcome to the Sieben Lab

We develop in-situ microfluidic sensors for environmental monitoring and for the deep ocean. Our current focus is the detection of nutrients, trace metals and bacteria. These compact, low-cost, and ruggedized sensors will be suitable for vast fleets of small autonomous water vehicles.

Please see our research section for more details.
