Jüergen Popp, a chair-holder of physical chemistry at the Friedrich-Schiller University Jena (Jena, Thuringia, Germany), was presented with the Pittsburgh Spectroscopy Award on March 8 at Pittcon 2016 in Atlanta, Georgia. He has served as the Scientific Director of the Leibniz Institute of Photonic Technology (Jena, Thuringia, Germany) since 2006.
Popp’s research interests are in the areas of biophotonics and material sciences, in particular, the development and application of innovative Raman techniques for biomedical diagnostics as well as environmental and food analysis. He and his group focus on the development of non-invasive photonic micro-spectroscopic methods for an in vitro and in vivo detection and characterization of heme and heme degradation products (HHDPs) and HHDP-peptide interactions.
Scientists Unveil Better Mixing Rule for Absorption Spectroscopy of Aerosols and Colloids
June 16th 2025Researchers have introduced a simple yet powerful new rule based on Rayleigh scattering theory that accurately links the absorption behavior of composite media, like aerosols or colloids, to the properties of their nanoparticle constituents.
Short Tutorial: Complex-Valued Chemometrics for Composition Analysis
June 16th 2025In this tutorial, Thomas G. Mayerhöfer and Jürgen Popp introduce complex-valued chemometrics as a more physically grounded alternative to traditional intensity-based spectroscopy measurement methods. By incorporating both the real and imaginary parts of the complex refractive index of a sample, this approach preserves phase information and improves linearity with sample analyte concentration. The result is more robust and interpretable multivariate models, especially in systems affected by nonlinear effects or strong solvent and analyte interactions.
