Shohei Katsuya is a dedicated Researcher at the Advanced Technology Laboratories of OSAKA GAS Co., Ltd., where he specializes in cutting-edge metabolic and nutritional research. He holds a Master of Agriculture degree from Kyoto University, completed in March 2021, and has since been actively involved in advanced investigations centered on the physiological functions and health impacts of beta-hydroxybutyrate (BHB). Since joining Osaka Gas in April 2021, Katsuya has contributed significantly to a series of clinical and biochemical studies exploring the therapeutic potential of BHB, a key ketone body known for its roles in metabolism, energy utilization, and physiological regulation. His research focuses on understanding the metabolic pathways and physiological effects of BHB in humans, with applications ranging from obesity reduction to improved sleep quality and metabolic health. He has authored five peer-reviewed publications between 2023 and 2025 in reputable journals including Obesities, Journal of Nutritional Science and Vitaminology, Bioscience, Biotechnology, and Biochemistry, and Nutrition. These works include randomized, double-blind, placebo-controlled clinical trials investigating the effects of D-BHB on body fat reduction, sleep quality enhancement, and its safety profile in humans and animal models. Additionally, he contributed to a collaborative study demonstrating BHB’s protective effects on diabetic renal and muscular pathologies.Katsuya’s publications have collectively received 18 citations and earned an h-index of 2 according to Scopus, reflecting the emerging impact of his work within the nutritional and biochemical sciences. His ongoing projects continue to deepen scientific understanding of BHB as a functional metabolite with potential applications in health optimization, disease prevention, and metabolic regulation. Through his work, Shohei Katsuya is advancing evidence-based insights that contribute to both academic knowledge and practical applications in human health research.

Shailendra Pratap Singh is an emerging researcher in Atmospheric Chemistry with a specialized focus on bio-aerosols and the biochemical and physical characteristics of particulate matter (PM₂.₅ and PM₁₀). He is currently pursuing a Ph.D. at Dr. Bhimrao Ambedkar University, Agra, where his research centers on understanding the chemical composition, microbial load, and environmental behavior of airborne particulates in urban regions. His academic foundation includes an M.Phil. in Chemistry with research on toxic metal levels in maternal and neonatal biological samples, and an M.Sc. in Chemistry, both from the same university. He has hands-on expertise with advanced aerosol and air-quality monitoring instruments, including the Grimm Aerosol Spectrometer, SKC Sioutas Cascade Impactor, Dichotomous Sampler, Fine Particulate Sampler, and Aerosol Black Carbon Monitor. His technical experience is supported by more than two and a half years as a Post Project Assistant in a state-funded research project focusing on indoor and outdoor particulate pollution in school environments and its associated health impacts. Shailendra has published research in prominent journals covering aerosol chemistry, metal concentrations in particulate matter, morphology of primary aerosol particles, seasonal pollution patterns, and black carbon variability. His contributions also include a book chapter with Springer on the geographic distribution and transport of atmospheric particulate matter. He has actively engaged in national training programs, workshops, and conferences organized by premier institutions such as IIT Delhi, IITM Pune, CSIR-NPL, CSIR-NEERI, and UNESCO-affiliated bodies. His scientific work has been recognized through conference presentations and awards, including Best Oral Presentation at an international conference. He has also been awarded the prestigious International Travel Grant by the Anusandhan National Research Foundation (ANRF) to present his work at the European Aerosol Conference 2025.
