My research centers on the photophysical and photochemical interactions between light and biological materials, with a focus on plant physiology and ecological optics. I employ advanced fluorescence and reflectance-based techniques to investigate pigment dynamics, photosynthetic performance, and stress responses in plants exposed to environmental pollutants such as lead, arsenic, vanadium, herbicides and organophosphates.
These studies include the assessments of variable chlorophyll fluorescence, time-resolved fluorescence imaging, and steady-state fluorescence. I developed several models to correct fluorescence spectra for light re-absorption and re-emission processes.
In parallel, I explore the functional role of bio-optical signals in animal-plant interactions, including natural fluorescence in amphibians and bird feathers. These studies aim to elucidate how optical traits contribute to ecological communication and signal evolution.
My work also addresses the translation of bio-optical signals into applied tools, such as fluorescence-based indicators of food quality and biosensors for environmental monitoring using aquatic macrophytes.
