About Luis Morales

Luis Orlando Morales is a Senior Lecturer and Docent (Associate Professor in Biology) at Örebro University, School of Science and Technology. He defended his PhD thesis in Plant Biology “Molecular Responses of Plants to Solar UV-B and UV-A radiation” at the University of Helsinki in 2014. Luis has also completed postdoctoral trainings at the Faculty of Biological and Environmental Sciences, University of Helsinki and at the Department of Horticultural Science, North Carolina State University before joining Örebro University in January 2019.

In his research, Luis combines genomics, physiology, molecular biology, bioinformatics and statistics to unravel molecular and physiological mechanisms mediating light perception and signaling in plants. Light is not only a source of energy for photosynthesis but also a key environmental factor that regulates several physiological processes in plants including growth, development, defense against pathogen and insect attacks, and acclimation to the environment. Different wavelengths of light are perceived through specific plant protein photoreceptors. Of these photoreceptors, UVR8 and cryptochromes perceive ultraviolet (UV) radiation and blue light, respectively. His goal is to understand the molecular basis of plant responses to UV and other wavelenghts of the spectrum mediated by UVR8 and cryptochromes, and to understand how plants integrate light signals with environmental factors including drought and temperature. Luis is also seeking applications of light signaling in horticultural settings that aim to improve crop production and quality.

Luis is the principal investigator of the research group Plant signaling and Physiology from the Life Science Center. He colaborates with different groups from the School of Science and Technology including Molecular Biochemistry and Metabolomics as well as the industrial partners Svenska Skogsplantor and Heliospectra AB.

Luis teaches and coordinates several courses in Biology including Plant Physiology, Eukaryotic Cell Biology and Experimental Design. He also teaches in the following Biology and Chemistry courses: Analytical Biochemistry, Biochemistry, Ecology, Biological Forensics, Biological innovations, Model organisms and Analytical Science and Forensics.
