Dr. Pisello is an associate professor of environmental applied physics at University of Perugia, Italy where she founded the Environmental Applied Physics Lab. She has been a visiting research associate at Princeton University (NJ), Columbia University (NY), Virginia Tech (Virginia) and City University of New York.

She is the author of more than 150 international refereed journal publications and several patents about microclimate monitoring systems, new materials for radiative cooling and photoluminescence. Dr Pisello has won several international academic awards and European projects under the framework of Horizon 2020 and Horizon Europe program including one European Research Council grant about radiative cooling for urban heat mitigation, as the first and only Italian scientist in the field of Environmental/Industrial Applied Physics. She is an associate editor of Solar Energy (Elsevier), editor of Energy and Buildings (Elsevier) and Nature Scientific Reports, among others.

Dr. Giribabu is a Senior Scientist at the CSIR-Indian Institute of Chemical technology (IICT), Hyderabad, India, and a Professor at the Academy of Scientific and Innovation Research (AcSIR).

His expertise is in the design and development of low-cost materials that include sensitizers, redox couples, electrode materials, semi-conducting metal oxides, and hole transport materials for dye-sensitized solar cells and perovskite solar cells. His group also investigates donor-acceptor systems-based pigment molecules for bio-mimicking of natural photosynthesis, non-linear optical properties as well as sensitizers for photodynamic therapy. He is the recipient of several awards including the Materials Research Society award, a Fellow of the Royal Society of Chemistry, and a Fellow of the Luminescence Society of India. He has published over 250 research articles, is an inventor on 7 patents and has published six book chapters.

Dr. Pitz-Paal is one of the two directors of DLR Solar Research Institute, the largest research institution in Germany working in the field of concentrating solar technologies. This position is jointly assigned with a professorship at Aachen University. 

His main research areas are the technical analysis and optimization of concentrating solar power systems for generating electricity and producing fuel. Many innovations developed in his institute can be found today in commercial solar thermal power plants. Dr Pitz-Paal has serves as associate editor the Journal of Solar Energy and served as the chairman of the SolarPACES technology Cooperation Programme of the IEA form 2017 -21. He is also member of the board of the German Industry Association of CSP (DeutscheCSP) and of the European Industry Association ESTELA. Pitz-Paal received the Farrington-Daniels Award of the International Energy Society in 2017 and the Frank Kreith Energy Award of the ASME in 2020.
