Postgraduate Coordinator | Bahir Dar University | Ethiopia

Dr. Solomon Addisu is a leading researcher in climate change, environmental systems, soil science, and sustainable land-use management, with a strong focus on Ethiopia and the broader East African region. His extensive body of work advances understanding of how climate variability, land degradation, agricultural systems, and natural resource pressures intersect to shape environmental sustainability and community resilience. Through more than a decade of scientific contributions, he has established himself as a significant voice in climate adaptation research, soil enhancement technologies, and watershed management.A central pillar of his research explores biochar technology, soil amendments, and nutrient cycling. His studies on water hyacinth-based biochar, phosphorus biofertilizers from animal bone, and the physicochemical transformations of biomass during pyrolysis offer pioneering insights into regenerative agriculture and soil rehabilitation. These works demonstrate the potential of low-cost, sustainable inputs to improve soil fertility, reduce acidification, enhance nutrient retention, and boost crop productivity—especially in degraded highland agroecosystems.Dr. Addisu is also widely recognized for his contributions to climate modeling, hydrological forecasting, and drought analysis. His research using CMIP6 scenarios, rainfall trend evaluations, and meteorological drought assessments provides vital actionable guidance for climate adaptation planning in vulnerable regions. He applies advanced geospatial tools, remote sensing, and machine learning to analyze land-use dynamics, watershed degradation, flood risks, and invasive species monitoring—most notably in the Lake Tana basin.Another core area of his work addresses environmental pollution, urban heat island effects, charcoal production impacts, and sustainable waste management solutions. His studies integrate socioeconomic, ecological, and policy perspectives, offering comprehensive frameworks for environmental governance, community-based adaptation, and nature-based solutions.Additionally, Dr. Addisu’s extensive research on climate change perceptions, rural livelihood vulnerabilities, agricultural resilience, and livestock diversification is widely cited in the fields of sustainable development and rural poverty reduction. His work equips policymakers and communities with evidence-based strategies to build resilience in the face of increasing climate stressors.Overall, Dr. Solomon Addisu’s research portfolio bridges environmental science, climate adaptation, soil restoration, and sustainable natural resource management. His contributions significantly strengthen scientific understanding and provide practical pathways toward ecological stability, food security, and climate-resilient development across Ethiopia and East Africa.

Dr. Shinichiro Sawa | Medicine | Best Researcher Award

Professor | Kyushu University | Japan 

Dr. Shinichiro Sawa is a highly accomplished Japanese immunologist and medical researcher renowned for his pioneering work in immune regulation, autoimmunity, and inflammation. He currently serves as a Professor at the Institute of Bioregulation, Kyushu University, Japan, where he leads innovative studies in molecular and cellular immunology. Dr. Sawa began his academic journey at Osaka University, earning his Medical Degree (M.D.) in 2000 and subsequently his Ph.D. in Medicine in 2006 from the same institution, where he developed a strong foundation in biomedical sciences and experimental medicine. His professional trajectory includes significant academic roles as Assistant Professor at the University of Tokyo (2011–2016) and Associate Professor at Hokkaido University’s Institute for Genetic Medicine (2016–2018) before joining Kyushu University in 2019. Dr. Sawa’s research interests center on understanding how immune cells, such as γδ T cells, fibroblasts, and plasma cells, interact with tissue environments to regulate immune tolerance, autoimmunity, and inflammatory diseases. His studies, published in prestigious journals such as Nature Immunology, Journal of Clinical Investigation, and Journal of Investigative Dermatology, have shed light on how fibroblasts contribute to central immune tolerance and how plasma cells promote osteoclastogenesis in autoimmune arthritis. His research skills encompass cellular immunology, molecular signaling analysis, animal modeling of immune diseases, flow cytometry, and translational immunopathology, demonstrating both depth and precision in experimental design and interpretation. Recognized for his scientific contributions, Dr. Sawa has received numerous academic honors and research recognitions throughout his career, reflecting his influence in the global immunology community. In conclusion, Dr. Shinichiro Sawa stands as a leading figure in immunological research, bridging basic science and clinical application to advance our understanding of immune homeostasis and to pave the way for novel therapeutic strategies against autoimmune and inflammatory disorders.
