Dr.Ruediger Grunwald currently holds the position of a Guest Scientist at the Max Born Institute for Nonlinear Optics and Short-Pulse Spectroscopy in Berlin, where he was active as a Project Researcher until his recent retirement. He completed his PhD studies at the Humboldt University in Berlin in 1986, and is a Fellow of SPIE and a Senior Member of Optica. He published more than 150 papers in scientific journals, with about 250 contributions to conferences, more than 20 patents, and books. He served as an Associated Editor for Optics Express, Scientific Reports and Applied Sciences, and as a reviewer for numerous journals and funding agencies. As a Guest professor he gave lectures on micro-optics and plasmonics. His project activities were focused on laser spectroscopy, resonators, thin-film micro-optics, characterizing and shaping ultrashort laser pulses, nonlinear nanooptics, laser-induced surface structures, and adaptive microaxicons. Particular highlights were neutral channels of multiphoton dissociation, nondiffracting X-pulses, plasmonic mechanisms of laser-matter interaction, highly localized wavepackets, statistical meta-moments, and orbital angular momentum beams.
