Javier Alejandro Donoso Quezada

Javier Alejandro Donoso Quezada is a Postdoctoral Research Fellow at the Department of Clinical Biochemistry, Faculty of Medicine, Aalborg University, Denmark. His research centers on extracellular vesicles and their role in intercellular communication within obesity, metabolic diseases, and cancer therapeutics.

His academic qualifications include:

• PhD in Biotechnology (2023), Aalborg University: Focused on exosome-like vesicles in obesity pathophysiology and therapeutic applications.
• Master of Science in Biotechnology (2019): Researched exosome-mediated delivery of black bean extract for enhanced anticancer bioactivity.
• Bachelor's in Biotechnology Engineering (2016).

Dr. Donoso Quezada's primary expertise lies in extracellular vesicles (exosomes) within biomedicine, utilizing proteomic and metabolomic techniques to investigate obesity, metabolic syndrome, and cancer mechanisms. His work spans fundamental cell biology to therapeutic development, including exosome-based delivery systems for natural compounds and biomarker discovery for liver diseases.

Recent publications (2024-2025) reveal a dual focus: advancing extracellular vesicle applications in metabolic liver diseases (NAFLD/MASLD) and environmental contexts (algal blooms). Key contributions include novel flow cytometry methodologies for vesicle isolation, microencapsulation techniques to enhance phycoerythrin's antiproliferative effects, and biomarker validation for weight loss interventions in steatotic liver disease.

He actively collaborates with multidisciplinary teams across clinical, environmental, and pharmaceutical research domains, contributing to UN Sustainable Development Goals in health and well-being through innovative biomedical solutions.
