CV of Pedro J. Aphalo

Bio. Pedro J. Aphalo is a lecturer in Plant Physiological Ecology an P.I. in the Organismal and Evolutionary Biology Research Programme of the University of Helsinki, Finland. He has a background in agriculture and some experience in forestry. He teaches “design of biological experiments”, “sensory and physiological ecology of plants” and “ecosystem ecology” in the M.Sc. Programme in Plant Biology. His main research interest is in “sensory ecology of plants” with emphasis on responses of plants to light and UV-radiation cues. His research group (see https://blogs.helsinki.fi/senpep-blog/) is using methods ranging from molecular tools to study plants’ mechanisms of perception and signalling, to radiation transfer modelling in the atmosphere and analysis of climatological data on solar radiation to investigate information-carrying cues in the environment. Current research is on Vicia faba, Medicago truncatula and Arabidopsis thaliana. In recent years his group has also studied various tree species from Betula, Alnus, Nothofagus, Fagus, and Tilia as well as some horticultural crop species. He is the editor of the UV4Plants Bulletin (https://bulletin.uv4plants.org/) and information officer of The International Association for Plant UV Research (https://www.uv4plants.org/). He has nearly 20 years of experience in the use and teaching of R, the free software environment for statistical computing and graphics. He is the author of 12 R packages available through the CRAN repository (see https://www.r4photobiology.info/) and is writing two books: “Learn R …as you learnt your mother tongue” (Chapman & Hall/CRC, 2019) and “Using R for photobiological calculations” (2020?). His main hobby is photography, which he frequently combines with research and teaching (https://www.photo-spectrum.info/).
