Muhammad Omair is a Postdoctoral Researcher at Aalborg University's Department of Materials and Production within the Faculty of Engineering and Science, specializing in sustainable operations and innovation management. His work bridges industrial engineering and environmental sustainability through advanced optimization techniques. Education Ph.D. in Industrial Management Engineering, Hanyang University (March 2016 - February 2019) Research Focus Dr. Omair's expertise centers on circular economy implementation in plastic supply chains, material requirements planning under uncertainty , and production scheduling optimization . His fingerprint reveals deep engagement with scheduling problems (100%), evolution strategies (84%), flowshop scheduling (84%), and carbon footprint reduction (31%). He actively contributes to UN Sustainable Development Goals through research on plastic recycling systems and sustainable production frameworks. Publication Trends Recent work (2023-2025) demonstrates a strategic shift toward integrating AI-driven optimization with circular economy challenges. His publications increasingly combine reinforcement learning for risk-averse decision making with practical applications in plastic recycling supply chains, while maintaining core contributions to non-permutation flow shop scheduling algorithms. This dual focus on theoretical optimization and tangible sustainability solutions defines his current research trajectory.
Mikkel Rathsach Andersen serves as a Clinical Associate Professor within the Department of Clinical Medicine at the University of Copenhagen, Denmark, with specialized clinical duties in Orthopaedic Surgery at the Capital Region of Denmark (Region Hovedstaden). His work is anchored at the Center for Fast-track Hip and Knee Replacement, where he contributes to pioneering accelerated surgical pathways for joint arthroplasty across multiple hospital sites including Herlev Hospital (Borgmester Ib Juuls Vej 1, 2730 Herlev) and Rigshospitalet (Blegdamsvej 3, 2200 København N.). Andersen's research program centers on optimizing perioperative care for hip and knee arthroplasty patients, with particular focus on enabling day-case and outpatient surgery in public healthcare systems. His investigations span comorbidity management (non-anaemic iron deficiency, diabetes), pain control protocols, and predictive modeling for surgical outcomes. He examines how interventions like perioperative steroids, nerve blocks, and tailored anaemia management influence length of stay, readmission rates, and functional recovery, directly informing evidence-based fast-track protocols that balance efficiency with patient safety. Analysis of his 2023-2025 publications reveals a cohesive research trajectory focused on fast-track arthroplasty implementation. His work consistently addresses barriers to same-day discharge through prospective multicenter designs, demonstrating that day-case protocols do not increase healthcare utilization while identifying modifiable risk factors like iron deficiency. Notably, his comparative study on machine learning versus logistic regression for morbidity prediction highlights growing integration of data science in perioperative decision-making, though clinical adoption remains cautious. Andersen operates within the internationally recognized Center for Fast-track Hip and Knee Replacement, a collaborative hub that integrates clinical practice, research, and education. His frequent co-authorship with perioperative medicine pioneers like Henrik Kehlet and Søren Overgaard demonstrates embeddedness in a robust research network, with publications generating significant Scopus citations and Mendeley readership. This work directly impacts public healthcare policy through evidence-based implementation of outpatient arthroplasty pathways across Denmark's public hospital system.
