Daniel Rebelo dos Santos
Assistant Professor
Instituto Superior Técnico
Daniel Santos is an Assistant Professor in the Department of Engineering and Management at Instituto Superior Técnico and the current Vice President of CEGIST. He earned his PhD in Optimization from the Faculty of Sciences of the University of Lisbon in April 2019, with a thesis titled “Models for Multi-Depot Routing Problems.” His primary research areas are routing and health care, with a focus on developing models, algorithms, and tools to support decision-making. He is the co-author of more than 15 articles in indexed, international, peer-reviewed journals and frequently collaborates with national and international researchers. He currently supervises five PhD students working on health care applications and combinatorial optimization, including topics such as home hospitalization, emergency medical services, the blood supply chain, operating room planning and scheduling, and university timetabling, and he has supervised more than 50 MSc students. He is the Principal Investigator of the FCT-funded projects “LAIfeBlood+ – Data Science for Blood Management” and “SUPPORT-HH: Decision Support Tools for Home Hospitalization Management.”

Projects
Service integration in healthcare – Balancing stakeholder interests and workflows in operating rooms
The aim of this project is to generate evidence and support tactical decisions in operating room management through new mathematical models.
Data2Help - Data science for the optimization of emergency medical services
Emergency medical services in mainland Portugal are coordinated by Instituto Nacional de Emergência Médica (INEM). In most cases, medical emergency situations are reported to INEM through a phone call to the 112 number, where specialized medical staff classifies the emergency situation and dispatches the proper emergency vehicle (ambulance, helicopter, life-support vehicle, among other) along with medical staff. Each vehicle is equipped to deal with different situations from light injuries to life-support.
ImproveOR - Decision support tools for better quality in operating rooms management
The ImproveOR project aims at improving efficiency in surgical care delivery and at improving access to surgical care, as a result of an increase of the operating room responsiveness to surgical demand and a better coordination between surgical supply and demand. Decision support tools are developed combining optimization approaches to assist resource capacity planning decisions in the operating room with structured participatory approaches to capture stakeholders’ views and preferences regarding the surgical patient flows and the planning and scheduling of surgeries.
