About

Dr. Samir Kumar Khanal is a leading authority in sustainable bioresource engineering, with a primary focus on anaerobic digestion, wastewater treatment, and the circular bioeconomy. His pioneering work bridges fundamental microbiology with practical system design, most notably advancing our understanding of microbial community dynamics in anaerobic reactors for efficient energy recovery from organic wastes. With over 15,000 citations, his research has profoundly shaped modern bioprocess engineering, particularly through seminal contributions to high-rate anaerobic treatment technologies and the valorization of food waste and agricultural residues. His critical review on recent advances in aquaponic systems (2025) underscores his commitment to integrated food-energy-water systems, highlighting nutrient recovery and water reclamation as key pathways to global food security. Dr. Khanal’s work has earned him numerous accolades, including the prestigious ASCE State-of-the-Art of Civil Engineering Award. His textbooks and widely-cited reviews serve as essential resources for students and researchers alike, cementing his legacy as a transformative figure in sustainable environmental biotechnology.
