Kristian Berg, Institute of Cancer Research, Oslo University Hospital, Norway
Professor Kristian Berg has been head of the Department of Radiation Biology for 13 years and leader of the PCI-group for more than 25 years. After his MSc in biochemistry he has more than 30 years of experience in experimental and preclinical research within the field photodynamic therapy (PDT). A major focus of his research has been to reveal the mechanisms involved in the therapeutic effects of PDT and implementing such knowledge towards clinical utilization. These studies has influenced on the development of 5-aminolevulinic acid esters into clinical use. Since 1995 the focus has been to utilize PDT as a platform, named photochemical internalization (PCI), for inducing intracellular delivery and activation of drugs that accumulate in endocytic vesicles. This includes macromolecular therapeutics under development for clinical use in e.g. recombinant immunotoxin therapy, antigens for cancer vaccination, gene therapy and oligonucleotides for inhibition of gene expression, nanotechnology as well as some chemotherapetics. Several clinical trials have been carried out on the PCI technology. This research has resulted in approx. 120 publication with Berg as coauthor and more than 400 peer-reviewed publications worldwide focusing on the PCI technology. In total, he has published more than 250 scientific publications on photobiological topics as well as 11 patents.

Yoshitaka Fukada, Graduate School of Science, University of Tokyo, Japan
Dr. Yoshitaka Fukada is an animal photobiologist and consistently interested in physiological roles and molecular mechanism of light signaling in animals. He is now Professor Emeritus of the University of Tokyo, and he has been Professor of The University of Tokyo, School of Science for 25 years (1995-2021) and Associate Professor of the University of Tokyo, Graduate School of Arts and Sciences for 3 years (1993-1995). He received Ph.D. in 1983 from Kyoto University under the guidance of Prof. Tôru Yoshizawa who won the Finsen Medal in 2000.
Dr. Fukada started his scientific career in Yoshizawa’s lab by finding that metarhodopsin II is a physiologically active intermediate of bovine rhodopsin. In his earlier scientific career, he endeavored to pursue biochemical and molecular biological studies on the retinal photoreception by photoreceptive opsins and the light-signal transduction process mediated by G-protein (transducin) in vertebrate visual cells. Dr. Fukada in Yoshizawa’s lab at Kyoto University purified four kinds of cone photoreceptor opsins for color vision, UV-Violet (SWS1), Blue (SWS2), Green (RH2), and Red (LWS) opsins from the chicken retinas, and cDNA cloning of the four color opsins revealed that the divergence of the color opsin genes are ancient to that of divergence of rhodopsin, a scotopic opsin. After Dr. Fukada started his own lab in 1993, he investigated the gene expression network regulating the four color opsins in the cone visual cells. Also, he found that C-terminal farnesylation of G-protein transducin gamma-subunit and heterogeneous N-terminal fatty-acylation of the alpha-subunit in rod cells are indispensable for the light signaling triggered by rhodopsin. He extended his interests to the photoreception in the pineal gland, and his group identified a new opsin and named it “pinopsin” after pineal opsin as the first example of opsins expressed in extra-retinal tissues of a variety of animal species. Recently, he has been focusing his efforts on revealing cellular and molecular processes important for not only the circadian clock oscillation but also its photic regulation. Together, he devoted to investigation of cellular and molecular processes important for the visual/non-visual transduction in photosensory organs and the photic regulation of the circadian clock.
Dr. Fukada also devoted great effort to academic activities, serving as president of The Photobiology Association of Japan (2015-2016), The Japanese Society for Chronobiology (2017-2022), and The Japanese Society for Comparative Physiology and Biochemistry (2020-2021). He also served as vice president of The International Union of Photobiology, Executive Board Member of IUPB (2009-2014), and he was elected as a Member of Science Council of Japan (2018-) to serve for scientific activities of the Japanese government. He has received a number of awards including Yoshida Memorial Award from The Japanese Society for Comparative Physiology and Biochemistry (1992), Young Investigator Award from The Japanese Biochemical Society (1992), The Zoological Science Award from the Zoological Society of Japan (2006), The Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology from MEXT, Japan (2014), The 3rd PAJ Award from the The Photobiology Association of Japan (2018) and Axelrod Lectureship Award from The European Biological Rhythms Society (2022).
Dr. Yoshitaka Fukada has actively steered his lab toward uncovering new-generation photobiology and his contributions to sensory photobiology for more than 40 years are of the highest caliber.

Angela Falciatore, CNRS, France
Angela Falciatore is Research Director of the French National Centre for Scientific Research (CNRS) and Director of the Research Unit “Chloroplast Biology and Light sensing in Microalgae” at the Institut de Biologie Physico-Chimique (IBPC) in Paris. Angela investigates the mechanisms by which light impacts the life of phytoplankton in the oceans. Her interest for marine biology and photobiology stems from the research performed at the Stazione Zoologica Anton Dohrn of Naples (SZN) in Italy, where she obtained a PhD in 2002, by performing pioneering research on the perception of environmental signals in marine diatoms. Particularly interested in the dynamic responses of photosynthetic organisms to light, she conducted post-doctoral research on the chloroplast-to-nucleus retrograde signalling in Chlamydomonas reinhardtii at the University of Geneva, Switzerland. Other activities at the Okazaki National Institute for Basic Biology, Japan (1997), and at the Carnegie Institution of Washington, Stanford University, USA (2003), contributed to enlarge her expertise in photobiology. In 2005, she started an independent research activity at the SZN, Italy. At the end of 2009, she got a permanent position from CNRS and moved her activity to France, first at Sorbonne Université and, since 2019, at the IBPC.
Her laboratory is dedicated to the study of light-driven processes (photosynthesis and photoperception) and chloroplast biology. Combining physiological, biophysical, biochemical, and genome-wide molecular approaches in marine diatoms, her team has characterized diversified photoreceptors, fostering novel hypotheses on the role of these sensors in controlling growth and adaptive responses in a marine context. She also uncovered the existence of a long-foreseen diatom circadian clock, which controls essential rhythmic processes in these algae. Her team is also contributing to disclose some of the diatom-specific photoacclimation properties, by identifying critical regulators of photosynthesis that also influence the natural variability of photoresponses.
Angela has received a number of awards including the ‘Career Development Award, Human Frontier Science Program Org. (HFSP) in 2006; the “Coups d’Élan” Prize for French Research- Fondation Bettencourt Schueller in 2018; the Prize “Laureata Illustre” University Federico II of Naples, Italy in 2019; The Prix des Sciences de la Mer – Marine Science Award, Académie Des Sciences, l'Institut de France in 2021. She has been elected member of the European Molecular Biology Org. (EMBO) in 2023.
