PhD Scholarship Position in Medical Science Multi-modal Neuroimaging

A fully-funded PhD fellowship in molecular imaging is available at University of Gothenburg. The funding allows successful candidate to work for 4 years. This position is closed on December 17, 2018.

The Department of Psychiatry and Neurochemistry is located at the Institute of Neuroscience and Physiology at the Faculty of Health Care Sciences at Sahlgrenska Academy, University of Gothenburg. At the Department research is conducted on human behaviour, neuropsychiatric processes as well as psychiatric treatment and diagnosis in close collaboration with Vstra Gtaland region and a number of international partners. We participate in the undergraduate programmes in Medicine and withinThe National Research School in Psychiatry/Southwest Sweden. At the Department there are some 15 research groups and four research centres.

Project title: Multi-modal neuroimaging to examine inter-induvidual differences in cognitive aging and their association with tau deposition

General information about third-cycle studies: The PhD education in Medical Science corresponds to studies of 240 credits in total. The studies are equivalent to four year full-time and lead to a Degree of Doctor. The studies comprisecarrying out a scientific project and completing at least 30 credits of courses at third-cycle level. The doctoral student must also write a scientific compilation thesis or monograph corresponding to at least 120 credits. For more information about third-cycle studies at Sahlgrenska Academy, see

Project:Aging is accompanied by a decline in episodic memory and working-memory, and much of the extant research in the cognitive neurosciences of aging has focused on identifying the neural correlates of this decline. Despite the general trend, however, there are distinct and important individual differences in cognitive aging. The brain undergoes multiple structural changes across human lifespan that can be studied and visualized in vivo at different scales. With molecular imaging techniques such as positron emission tomography (PET), specific changes on the molecular level such as aggregates of proteins can now also be visualized.

Recent research using PET ligands that bind to hyperphosphorylated paired-helical filaments (PHF) of tau protein, has stipulated that tau aggregation follows distinct spatial and temporal patterns, confirming established knowledge from post mortem studies of brain tissue. It also validated in vivo that tau aggregation, particularly in MTL, is abundant in aging and not exclusive to neurodegenerative diseases such as Alzheimer's disease (AD). However, the importance of MTL tau deposition in relation to memory decline seen in normal cognitive aging is still unclear. A strong association between tau in MTL and memory impairment has been shown, strengthening the hypothesis that tau pathology plays a key role in memory decline in aging, which is also strongly related to dysfunction of MTL structures. In this PhD project, we make use of recent developments of a second generation of tau PET ligands and leverage an existing longitudinal data set with rich information on retrospective cognitive change and MRI markers of brain aging (e.g. hippocampal atrophy and white matter integrity; BETULA study) to study how individual differences in quantity and regional distribution of tau deposition are associated with retrospective trajectories of cognitive change and brain integrity.Moreover, we aim to deliver methods to improve correction for inherent issues of unspecific binding and partial volume effects of tau PET ligands which hamper accurate quantification of ligand binding especially in the MTL as this study focusses on tau burden in this region. To be eligible for third-cycle studies, the applicant must meet both the general and specific entry requirements.

A person meets the general entry requirements for third-cycle studiesif he or she:

1. has been awarded a second-cycle qualification 2. has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or 3. has acquired substantially equivalent knowledge in some other way in Sweden or abroad A person meets thespecific entry requirements for third-cycle studiesif he or she: has successfully completed the English B/6 course or is considered to have acquired equivalent knowledge through previous studies

In selecting between applicants who meet the general and specific entry requirements, their ability to benefit from third-cycle studies shall be taken into account. The assessment shall attach particular importance to documented qualifications for:

– specific knowledge and skills within the subject area and related research fields – experience of scientific theory and relevant research methodology – scientific analysis and presentation verified through thesis, degree project, scientific journals or the like. Documented experienceof PET and MRI,and in medical imaging work is of value, as well as experience in programming in MATLAB, R and Python.Abackground of statistical data analysis is desirable as well asgood knowledge of English at scientific level.Great emphasis will be placed on personal qualities and suitability.

Time limited employment (temporary),4 years.Extent:100%. Location: Sahlgrenska Academy, Institute of Neuroscience and Physiology, Department of Psychiatry and Neurochemistry. First day of employment: as agreed.

Regulations for employment of doctoral students are given in SFS 1998:80.Only those who are admitted to third-cycle studies may be appointed to doctoral studentships. Those appointed to doctoral studentships shall primarily devote themselves to their studies. They may, however, work to a limited extent with educational tasks, research and administration according to the regulations.

The initial appointment may apply for no longer than one year. An appointment may be renewed for no more than two years at a time. The total employment period may not exceed the time corresponding to full-time third-cycle studies for four years.

Salaries for doctoral students are regulated in a local agreement at the University.
