[1] Following his doctorate, Reimer served as postdoctoral fellow at IBM T.J. Watson Research Laboratories, before joining University of California at Berkeley as assistant and associate professor in 1982.
Since 1984, he has also served as faculty scientist at Ernest O. Lawrence Berkeley National Laboratory, and in 2006, he held a brief appointment at RWTH Aachen University as Mercator Professor of the Deutsche Forschungsgemeinschaft.
[10][11] Reimer developed materials and membranes that enable energy-efficient separation of gas mixtures, and are required in the clean use of fossil fuels and in reducing emissions from industry.
[15] In 2002, Reimer developed magnetic resonance (MR) sensors[16] for pulp and paper processing applications under American Forest Products Association and DOE’s Office of Industrial Technology.
Furthermore, he developed a high throughput NMR relaxometer that yields nanoporous materials surface area with a robotic device, and later on extended the sensor concepts in his collaboration with Alex Pines towards “outside the magnet” and “outside the coil” detection.
