Phd Candidate In Airflow Distribution, Heat/Mass Transfer And Ventilation In Hospital Environments

Job Details

About the job

The Department of Energy and Process Engineering has a vacancy for a 3-year PhD position in indoor environment quality, airflow distribution, heat/mass transfer and ventilation in hospital environments.

The position as a PhD candidate is a fixed-term position with the primary goal of qualifying for work in professional academic positions or in positions industry, which require a high level of research-based competence. The position will be part of the Sustainable Energy Systems research group at EPT.

NTNU invites applicants for a PhD position in Environment Engineering to research “Airflow distribution and heat/mass transfer in the surgical site microenvironment in operating rooms”. The research topic will be contextualized in WP1 “Structure of new scientific knowledge on the physical mechanisms for pathogen exposure and engineering strategies for controlling risk”, being supervised by Professor Guangyu Cao and Professor Emeritus Hans Martin Mathisen at EPT, NTNU and Dr. Kim Hagström from Halton, with two secondments. One secondment will be at the Technical University of Berlin (3 months) and supervised by Professor Martin Kriegel, to carry out laboratory experiment of microenvironment parameters generated by surgeons and medical staff, and gain new knowledge of advanced measurement instruments, including Particle Image Velocimetry (PIV). The second secondment (3 months) will be in Halton, Finland, to carry out in-suit experimental measurements to validate the models of operating room microenvironment and gain experience of industry research environment.

The candidate will acquire expertise in interdisciplinary fields, gaining through this training program a set of skills that are highly appreciated by health care facilities, providing the candidate with valuable expertise for a future career in the topics related to technical solutions for healthcare facilities. Your immediate leader is the Head of Department. 

The position as a PhD candidate is in the frame of a Horizon Europe Marie Skłodowska-Curie Innovative Doctoral Networks (DN) action for Doctoral Candidates within the project HumanIC (Human - Centric Indoor Climate for Healthcare Facilities), to be recruited in September 2024.

The HumanIC network is composed by 8 universities, 2 hospitals and 9 companies/institutions to train early stage engineers and scientists to enable a new approach to the human-centric indoor climate in Healthcare Environments. In total, the HumanIC network consists of 11 Doctoral Candidates (DCs). Rather than the traditional approach of focusing solely on the building and its ventilation/heating systems, the network will develop new approaches to integrate the multi-dynamic interaction between contamination sources and airflow distribution systems with the clinical, patient and energy requirements of the hospital environment. More information can be found on the project website.

Through an ambitious research programme and a tailored training programme, HumanIC will provide a new generation of scientists and engineers who understand the implications of these complex interfaces in future hospital design. In building the HumanIC consortium we will actively promote healthcare environment engineering as an inclusive and diverse career option at all stages in the programme.  

Background

The human-centric indoor climate (HCC) is defined as the microenvironment which surrounds and is close to a human body. The HCC concept focuses on human beings and surrounding environment, which should be understood as a specific microenvironment more than just the ‘physical neighborhood’ of a human body. The HCC in hospitals plays a vital role in enabling safe and effective provision of healthcare. Operating rooms (ORs), isolation rooms, treatment rooms and laboratory facilities all enable increasingly sophisticated treatment to be safely delivered to patients, while wards, consulting rooms and waiting rooms provide essential facilities for the interaction of patients and their comfort and wellbeing during recovery. However, there are significant challenges of HCC within hospital environments. Over 4 million patients are estimated to acquire a healthcare-associated infection (HAI) in the EU each year, and on any given day, about 80 000 patients have at least one HAI, i.e. one in every 18 patients in European hospitals.

Duties of the position

An Initial Research Project (IRP) in HumanIC will be assigned to the PhD candidate (DC04) at the beginning of the fellowship. The PhD candidate (DC04) will have the responsibility of executing all the tasks described in the IRP of DC04, which will involve research and organization tasks, mobility requirements, milestone accomplishments and deliverable submission. The PhD candidate (DC04) will primarily work on research activities carried out as part of the research project HumanIC. The position will focus on the experimental data collection and modelling of the generation and short-range distribution of airborne microbial pollutant from human activities in hospital environments. For example, a non-exhaustive list of tasks to be carried out in this PhD research covers:

  • to develop a comprehensive experimental protocol for characterizing airflow distribution and heat/mass transfer in the surgical microenvironment of operating rooms during real-time operation and in a realistic, full-scale operating room laboratory setting;
  • to perform measurements airflow distribution and heat/mass transfer in the surgical microenvironment of operating rooms in hospital environments;
  • to develop a series of models that will be derived from experimental measurement to characterize the airflow distribution and heat/mass transfer in the surgical microenvironment of operating rooms;
  • to validate numerical model that simulates the airflow distribution and heat/mass transfer in the surgical microenvironment of operating rooms in operating room healthcare environments;
  • to cooperate with other research groups at partner universities/research institutes for the evaluation and optimisation of the experimental methods;
  • enroll in the PhD programme at Norwegian University of Science and Technology, Norway, and carry out all the activities required to make a high quality PhD dissertation within the expected timeframe. Publications in high impact-factor international journals are expected. 

During this fixed-term period, the candidate will spend 3 months in TUB to carry out laboratory experiment of microenvironment parameters generated by surgeons and medical staff, and gain new knowledge of advanced measurement instruments, including Particle Image Velocimetry. In addition, the candidate needs to spend another 3 months in Halton, Finland, to carry out in-suit experimental measurements to validate the models of operating room microenvironment and gain experience of industry research environment.
