Nina Karalija
I am a postdoc at diagnostic radiology in Professor Lars Nyberg’s group. My background consist of a master of science in chemical engineering, and a doctoral thesis in neuroscience.
My previous and present research has focused on functions regulated by the dopamine system. At present, I am part of the Cognition, Brain, and Aging (COBRA) project, which aims at evaluating the link between dopamine system integrity and cognitive performance in normal aging.
The dopamine system is a particularly age-sensitive network implicated in cognitive processes. Consequently, different routes of cognitive aging may depend on the status of the dopamine system. The COBRA cohort consists of 181 healthy, older adults that have undergone positron emission tomography to assess dopamine D2-receptor availability, magnetic resonance imaging for measures of brain structure and function, and broad-ranged cognitive assessment.
I was recently awarded a two-year postdoc scholarship from the Swedish Brain Foundation. The project will examine effects of genetic variation on inter-individual differences in dopamine measures and cognitive performance in the COBRA-sample.
This study has the potential to map predictors of age-related cognitive decline. Such knowledge is needed as severe decline compromises the well-being for a large number of individuals.

Phd/MD Danel Öhlund,
I have a specific interest in, and previous experiences of, pancreatic cancer microenvironment research. In my thesis I studied the role of the tumor stroma as a prognostic and diagnostic marker, and as a regulator of pancreatic tumor growth. We found that the increased expression and deposition of extracellular matrix (ECM) proteins in tumor tissue was reflected in the circulation, and that increased levels of ECM-derived protein fragments in the circulation correlated with poor prognosis. During my postdoctoral period in the Tuveson Laboratory at Cold Spring Harbor, New York, I continued to study the tumor microenvironment, focusing on the composition of the tumor stroma, and how interactions between cancer cells and tumor stroma impact on tumor progression and drug resistance. During this period, I developed a new organotypic co-culture system for studying stromal interactions, and I was also trained in using genetic engineered mouse models of pancreatic cancer.
I have recently been selected for an assistant professorship at Wallenberg Center for Molecular Medicine (WCMM) at Umeå University, and as a WCMM fellow I will continue to work on the tumor microenvironment. I will focus on deciphering the functional heterogeneity of stromal components within the tumor microenvironment, aiming to identify drugable stromal interactions driving tumor progression and to develop inhibitors to these interactions.

For men with intermediate risk prostate cancer, side effects at two years following radiation therapy (RT) were comparable for extremely-hypofractionated treatment, which was delivered in seven fractions across two and a half weeks, and conventional treatment of 39 fractions across eight weeks, according to research presented by professor Anders Widmark at the
58th Annual Meeting of the American Society for Radiation Oncology (ASTRO).

My name is Anneli Sundkvist (previously Marklund). I graduated in Medicine in June 20116 and have now started my research and medical internship at Norrlands University Hospital. I will be working with MD, PhD Bethany van Guelpen and PhD Sophia Harlid (Department of Radiation Sciences) on a project focusing on finding early biomarkers for colorectal cancer in blood. The project involves metabolomics, biomarkers for inflammation, and analysis of methylation in white blood cells.
After receiving my PhD in Chemistry at Umeå University in 2006, I have been working with research at the department of Environmental Chemistry and at the Department of Public Health and Clinical Medicine. During my Doctoral studies I were to investigate levels, distribution patterns and sources of organophosphorus (OPs) flame retardants and plasticizers in different environmental compartments. Indoor and outdoor environments, biological samples and human exposure to OPs were investigated in order to generate data which may be used for risk assessments. An additional aim was to develop analytical methods which could be utilized to analyse OPs in different matrixes.

In September 2016, PhD Anton Lindström begun his research and medical internship at Norrlands University Hospital. He will be working I collaboration with PhD Maria Sandström and PhD Tufve Nyholm (Department of Radiation Sciences). Their project involves detecting treatment response in glioma tumors using multivariate data analysis (MDA) of magnetic resonance-images.
Anton was awarded his PhD in Chemistry in 2009 and continued with his Post Doc research at the Department of Radiation Sciences Umeå University until 2012. In 2012 he was also accepted for medical studies at Umeå University and graduated in 2016, and alongside his medical studies he has continued with research focused on characterization of mouse glioma tumors using near infrared spectroscopy.
During his academic career his research has been strongly influenced by the application of tools for multivariate data analysis (MDA). In his PhD studies, MDA was applied for exploring the interaction between the active-site of proteins and drug-like ligands. And in his Post Doc work, MDA was used for the design of optimal MRI sequence settings for the enhancement of bone signal.
Anton is very happy to be part of the research group and is estimated to continue with his joint research and clinical internship at least until September 2019.

Anna Rieckmann
has received 1.5 Million Euros for a 5-year research project from an ERC Starting Grant.
ERC Starting Grants are awarded by the European Commission to young talented researchers with a promising track-record, with the aim of encouraging them to become independent research leaders. Anna joined the Department of Radiation Sciences (Diagnostic Radiology) when she returned to Sweden after a 3-year post-doc at Harvard University in the US. In her new research project, Anna will use simultaneous PET/MR to study the metabolic basis of the fMRI signal during cognitive control.
She hopes to gain new insights into the neural basis of cognitive functioning in early adulthood and aging.

My name is Sophia Harlid and I recently started full time as a senior research engineer at the department of radiation Sciences. I received my PhD in molecular epidemiology at Lund University in 2011 and after that I spent about 5 years at the National Institute of Health in the US as a postdoctoral fellow.
During my PhD I focused on evaluating genetic risk factors for breast cancer while incorporating environmental components. As a postdoc I investigated the effect of the environment on DNA methylation in blood and tissue, and how external exposures can increase cancer risk through epigenetic modifications. I currently work with Dr. Bethany Van Guelpen at Umeå University on a project focusing on biomarker discovery in early colorectal cancer.

My name is Karen Støverud and I will work as a research engineer in the Radiation Physics and Biomedical Engineering group.
The main focus of my work will be on computer simulations of intracranial blood and CSF flows.
I hold a PhD degree in computational mathematics from the University of Oslo, Norway, and a MSc degree in hydrology from Utrecht University, the Netherlands. In my master thesis I studied intracranial fluid flow with application to drug delivery in cancer treatment.
After my MSc degree I moved to Oslo where I did my PhD at Simula Research Laboratory. During my PhD I continued to study fluid flow in the brain. The topic of my thesis was the relation between the neurogical disorders Chiari I and syringomyelia from a mechanical perspective. I used computational fluid dynamics (CFD) to test hypotheses and get a better understanding of CSF flow and pressure under healthy and pathological conditions

August 19 begins Wendy Yi-Ying Wu as Senior research engineer at Radiation Sciences. She obtained her PhD from Division of Biostatistics, Graduate Institute of Epidemiology and Preventive Medicine, National Taiwan University in 2013.
Wendy has been working as a postdoctoral research fellow at Department of Radiation Sciences, Oncology in Umeå University since August 2014.
Her research focuses on the application of statistical methods to the medical field, especially with regard to developing the evaluation method in breast cancer screening.
She has developed a non-homogenous multistate model on estimation of overdiagnosis without using the historical or geographical control groups.

Tommy Löfstedt started a post-doc position here at Radiation Physics and Biomedical Engineering on January 18.
He will conduct research in feature extraction from multi-parametric
PET/MR images and use data analysis/machine learning to analyse these images.

After a master's degree in mathematics and one in computational science and engineering, Tommy started a PhD in computational science and engineering, where he developed methods for the analysis of so called multiblock data, i.e., data collected on the same patients or on the same samples with several different collections methods, and simultaneously integrated in one and the same data analysis model.

Tommy received his doctoral degree in 2012 and shortly after that begun a post doc position in machine learning at NeuroSpin (a neuro-imaging centre within the Commissariat à l'énergie atomique et aux énergies alternatives, CEA) in Saclay (Paris), France, where he developed data analysis methods for the analysis of MRI images from patients with neuro-cognitive diseases.
