Project description

Third-cycle subject: Physics

KTH and the Medical Imaging Physics group are at the forefront of research in new technologies for medical imaging, encompassing both the development of advanced hardware and software for image reconstruction, algorithm development, and other computational methods. The work of our research group has so far resulted in three spin-off companies, as well as a number of innovations that have been installed in clinics in over 30 countries and used in more than 10 million patient examinations. In independent evaluations of the research conducted by our group, we have consistently received the highest ratings, both for scientific excellence and societal impact. For more information, please visit our website.

We are now seeking a PhD student who wishes to apply their high-level expertise in mathematics, deep learning, and programming to develop new algorithms and computational models aimed at significantly improving the diagnostic quality of molecular imaging (read more about the project here). The research focuses on advanced image and signal processing, statistical modelling, and machine learning, tailored to large and complex datasets and clinical requirements for high accuracy, robustness, and computational efficiency. For the right candidate, this project offers the opportunity to work on problem formulations where advances can have a direct impact on the early detection and treatment of diseases such as cancer and cardiovascular conditions, and where theoretical expertise is translated into solutions that make a real difference for patients and healthcare.

Supervision: Assistant Professor Mats Persson is proposed to supervise the doctoral student. Decisions are made on admission

Admission requirements

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

• passed a second cycle degree (for example a master’s degree), or
• completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
• acquired, in some other way within or outside the country, substantially equivalent knowledge

To be admitted to doctoral studies in the subject of physics the applicant must have completed course requirements of at least 60 second-cycle higher education credits in physics or other subjects deemed to be directly relevant for the specialization in question. These requirements are seen as fulfilled also by someone who has acquired substantially equivalent knowledge in some other way.

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6.

Selection

In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

• independently pursue his or her work
• collaborate with others,
• have a professional approach and
• analyze and work with complex issues.

Additional meriting knowledge, skills and traits include:

• Excellent skills in mathematics
• Excellent skills in deep learning
• Excellent numerical programming skills
• Good spoken and written English communication skills as it is required in daily work

After the qualification requirements, great emphasis will be placed on personal skills. 

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years’ time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time. 

As a doctoral student, you are entitled to a workplace with many employee benefits and monthly salary according to KTH’s Doctoral student salary agreement. Read more about Doctoral studies (PhD) | KTH | Sweden.
