Lennard Mooij PhD MSc

Dutch patent attorney

Lennard Mooij

Areas of expertise:
Materials science, physics, energy storage and conversion

Delft University of Technology, Materials Science & Engineering

In 2015, Lennard started working as a trainee patent agent for Arnold & Siedsma. He previously worked as a researcher at Uppsala University in Sweden and at Delft University of Technology in the Netherlands. His worked primarily focused on the technical and scientific aspects of energy-storage materials. In this respect, Lennard also gained a large amount of hands-on laboratory experience with a broad spectrum of measuring techniques.

While pursuing his doctorate at Delft University of Technology, Lennard researched materials for hydrogen storage and hydrogen sensors. This resulted in various publications. During this time, Lennard worked together with researchers from other institutes, including for example, Antwerp University. He gained in-depth experience with, among other things, thin film, battery and solar cell technology and materials for energy storage and sensors.

Others about Lennard:
