PhD-student in Technology

Department of Energy and Technology Third-cycle subject area Technology Description of the doctoral project Food waste has received increasing attention in recent years, and reducing food waste throughout the food supply chain is important for achieving sustainable development. In elderly care, food waste is particularly problematic as it both represents unnecessary resource use and may indicate insufficient nutritional intake among older adults. Automatic measurement systems can provide long and continuous datasets that improve understanding of when, where, and why food waste occurs. About the position We are seeking a doctoral student to work on the development and refinement of automatic measurement systems for food waste. The systems are based on weighing scales and single-board computers (e.g. Raspberry Pi) equipped with cameras that automatically register food waste. The work includes further developing existing hardware and software, testing and validating the measurement systems in real-world environments, and applying them among consumers in private households, schools, and elderly care facilities. The position also involves analysing collected data, evaluating the reliability and usability of the systems, and developing a categorisation system. The aim of the project is to develop measurement systems that can be used to evaluate interventions designed to reduce food waste among consumers. The work will be conducted in collaboration with stakeholders and project partners, and travel may therefore be required. Requirements To meet the general entry requirements you must have been awarded a second-cycle (Master's) qualification, satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or acquired substantially equivalent knowledge in some other way in Sweden or abroad (Higher Education Ordinance 1993:100, Chapter 7, Section 39). Specific eligibility for admission to doctoral studies in Technology is granted to applicants who have knowledge equivalent to at least 90 credits in courses relevant to the field of technology. These studies must include an independent degree project/thesis, and at least 30 credits must be at second-cycle (Master's) level. In other cases, specific eligibility will be assessed individually with regard to the research project. You must also meet the equivalent English language requirements as those necessary for the Swedish upper-secondary qualification Engelska B/6. Your profile Requirements Master's degree in a relevant field such as engineering, food science, computer science, electrical engineering, mechatronics, or a related discipline. Excellent communication skills in English, both written and spoken.

Meritorious qualifications Experience working with single-board computers and/or embedded systems such as Raspberry Pi or Arduino. Experience in programming with Python. Knowledge of sensor technology, IoT, and data collection systems. Experience with image recognition technologies (e.g. OpenCV, TensorFlow, or similar). Experience in prototype development involving both hardware and software. Knowledge of food waste and food systems. Experience in data analysis and statistical methods. Experience in scientific writing and communication. Ability to communicate in Swedish. Valid category B driving licence. Great emphasis will be placed on personal qualities such as collaboration skills, analytical and problem-solving abilities, and the capacity for independent work.
