Ingrid Wilke joined RPI as an assistant professor of physics
in 2002. Prior to her appointment at RPI, she spent seven
years as a senior research associate (C1) at the University of
Hamburg's (Germany) Institute of Applied Physics. She has
done post-doctoral work at both the University of Tokyo's
Institute of Industrial Science and at the Lawrence Berkley
National Laboratory, Materials and Chemical Science division.

Time-domain Spectroscopy and Ultrafast
Ingrid Wilke’s research is focused on the development of narrow band gap semiconductors as sources of THz-radiation for
time-domain THz-spectroscopy and imaging systems. Another area of research is the measurement of the dielectric function
of materials in the THz-frequency range using time-domain THz spectroscopy. Materials of interest are glasses, ceramics,
semiconductors, superconductors and biological tissue.
Time-domain THz-emission measurements, time-domain THz transmission and reflection spectroscopy, phase-sensitive backward
wave oscillator based THz-spectroscopy, femtosecond optical transient reflectivity and transmittivity measurements, femtosecond
optical four-wave mixing, femtosecond laser nanoprocessing of living cells and fluorescence microscopy.
