Alexej Pashkin

Alexej Pashkin is a Senior Researcher at the Spectroscopy Department of the Institute of Ion Beam Physics and Materials Research at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). He also holds the academic title of Privat-Dozent at the University of Konstanz, Germany, reflecting his advanced postdoctoral qualifications and teaching experience.

• PhD in Physics, Charles University, Prague (2004)
• Habilitation in Physics, University of Konstanz (2014)

His research is centered on ultrafast optical and terahertz spectroscopy of quantum materials. Key research areas include:

• Strongly correlated electron systems and high-temperature superconductors
• Semiconductor nanostructures such as GaAs and InGaAs nanowires
• Materials under extreme conditions like high pressure
• Ferroelectric and multiferroic materials

His recent publications demonstrate a strong focus on ultrafast carrier dynamics, terahertz photoconductivity, and nanoscale electronic transport. The work spans fundamental physics of phase transitions to applied optoelectronic device development, particularly in the terahertz regime. Articles in journals like Nature Communications and Light: Science & Applications highlight both scientific impact and technological relevance.

Awarded scientific roles include:

• Member of Program Advisory Committee for the HFML-FELIX facility
• Member of Advisory Panel for Journal of Physics D
• Editorial Board Member of Photonics journal
• Referee for major publishers (NPG, APS, AIP)

Dr. Pashkin has actively contributed to academic training through lecturing and tutoring roles at the University of Konstanz, including courses on Laser Physics, Nonlinear Optics, and Optical Solid-State Spectroscopy.
