Dr. (Mrs.) Blissbern Appiagyei Osei-Owusu is an environmental scientist with a strong focus on sustainable waste management practices and bioresources valorization technologies. Her research is pivotal in advancing sustainable waste management strategies, particularly in developing countries, emphasizing landfill gas mitigation and waste-to-energy solutions.

Dr. Appiagyei Osei-Owusu holds a PhD in Environmental Sanitation and Waste Management from the Civil Engineering Department of Kwame Nkrumah University of Science and Technology (KNUST), funded by the World Bank under the Regional Water and Environmental Sanitation Centre, Kumasi (RWESCK). Her doctoral research, "Enhancing Biogas Recovery from Anaerobic Co-digestion of Human Excreta and Food Waste using Response Surface Method and Biochar Additives," explored innovative approaches to enhancing biogas production, facilitating better waste management practices.

Additionally, Dr. Appiagyei Osei-Owusu earned an M.Sc. in Environmental Engineering from the Technical University of Denmark (DTU) under the prestigious Building Stronger Universities Master Scholarship by DANIDA. She also holds a Postgraduate Diploma in Earth System Physics and a Bachelor of Science in Physics with a specialization in Geophysics from the International Centre for Theoretical Physics (ICTP-Italy) and KNUST, respectively.

Dr. Appiagyei Osei-Owusu's research spans multiple domains of environmental science, with a particular focus on the following key areas:

• Circular Bioeconomy and Bioresources Valorization:  Applying biotechnological solutions to waste treatment, resource recovery, and waste-energy technologies, especially anaerobic digestion.
• Sustainable Waste Management: Developing and implementing effective waste management strategies, particularly in developing countries.
• Greenhouse Gas Emission Studies: Conduct studies on the release and mitigation of landfill gases and their impact on climate change. Also, investigating methods for methane oxidation.
• Heavy Metal Contamination: Quantifying the presence of heavy metals in liquid and solid waste materials.
