My watch list


Dr. Helene M. Loos

Friedrich-Alexander-Universität Erlangen-Nürnberg, Lehrstuhl für Aroma- und Geruchsforschung und Fraunhofer-Institut für Verfahrenstechnik und Verpackung IVV

Helene Loos studied food technology at the University of Hohenheim and completed her doctorate in food chemistry at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in 2015. During her doctoral studies, she investigated the aroma composition of breast milk and the behavioral responses of newborns to selected odorants from sweat and milk under the supervision of Professor Dr. Andrea Buettner and Dr. Benoist Schaal at the Fraunhofer Institute for Process Engineering and Packaging IVV, Freising, and the Centre des Sciences du Goût et de l'Alimentation, Dijon. After her PhD, she conducted research at the Fraunhofer IVV in the Sensory Analytics department focusing on sensory evaluation and multisensory perception in cooperation with Professor Dr. Jessica Freiherr, RWTH Aachen. In 2017, she started her independent postdoctoral research work at the Department of Chemistry and Pharmacy, FAU. In the course of this activity, she has successfully acquired numerous third-party funded projects, including an Emerging Fields Initiative project launched in April 2019 that enabled her to establish a junior research group.


The current research activities of the research group of Helene Loos at the Chair of Aroma and Smell Research at FAU follow two major lines of research. On the one hand, the group studies the psychophysiological reactions of humans to olfactory stimuli. This work was initially funded by the program “Förderung der Chancengleichheit für Frauen in Forschung und Lehre“ (FFL). In addition, as part of an Emerging Fields Initiative project, Helene Loos and her colleagues have established a methodological platform to investigate the chemical and biological basis of body odor formation and the role of body odors and volatiles in human chemical communication. Helene Loos is one of the lead scientists of the “Campus of the Senses” and “Sensory Sciences” initiatives at FAU and Fraunhofer IVV.


In 2021, Helene Loos received the Women's Faculty Award from the Faculty of Natural Sciences at FAU for her junior research group “Olfactory Perception and Chemocommunication”.


The research interest of Helene Loos is in the fields of aroma analysis, olfaction and perceptual psychology. Her group investigates the mechanisms of perceptual and behavioral phenomena in olfaction and applies a range of methods to identify and quantify odorants and their metabolites in biological samples. It characterizes odor-active substances in terms of psychophysical parameters and investigates their potential function in modulating behavior. The two main research areas are the analytical characterization of odor-active and odorless volatiles and the investigation of the perceptual and physiological effects of odor-active volatiles.

    Nano-Rust: Smart Additive for Autonomous Temperature Control

    The right temperature matters – whether in technical processes, for the quality of food and medicines, or the lifetime of electronic components and batteries. For this purpose, temperature indicators record (un)desired temperature increases that can be read out later. Researchers in the gro ... more

    More than a coffee ring

    What do coffee, red wine and ink have in common? The stubborn stains they leave behind. Anyone who has ever knocked over a cup of coffee will know that coffee dries in an unusual pattern, the stain is lighter at the center but it gets darker around the perimeter, an effect known as the coff ... more

    By capsule through the bloodstream

    Bacteria in the intestine pack a wide spectrum of their biomolecules into small capsules. These are transported via the bloodstream to various organs in the body and even absorbed and processed by nerve cells in the brain. This has now been shown for the first time by a team of researchers ... more

    Transfer of aroma compounds into breast milk

    “We are what we eat.” In a way, this quote by the German philosopher Ludwig Feuerbach (1804–1872) also applies to what we feed our offspring: the aroma profile of breast milk reflects a mother's eating habits [1, 2] and can thus influence the preferences of her children ... more

    Colorful off-odors in artists’ paints

    Acrylic-based paints are among the most frequently used by artists. Although they can be produced on a water basis and with low levels of volatile substances, they often still possess a strong inherent smell. However, no targeted studies have as yet been conducted to identify odor-active su ... more

    New Trends in Computer-Aided Drug Design

    Computer-Aided Drug design (CADD) is not new. The Journal of Computer-Aided Molecular Design (Springer) was founded in 1987, when computers in the worldwide top 500 were slower than today’s smart phones. This makes the field a quarter of a century old. Generally, scientific disciplines of t ... more
