Ongoing projects

Understanding Headach Through Registry Data - A NorHEAD MiHEAD project (2024-)

The aim of the study is to improve the understanding and treatment of primary headache disorders by using multiple linked Norwegian registries and health surveys.

Role: Statistician. 

Exposure Assessment and Prevention of Death, Disease and Injuries amon Offshore Petroleum Workers (2024-)

The aim of the work package in the study is to update job-exposure matrices for benzene and oil mist/vapour.

Role: Statistician. 

Childhood cancer survival in countries in transition (2023-)

In this project, we aim to produce survival estimates for childhood cancer in countries in transition. The work is carried out at the Cancer Surveillance Unit at the International Agency for Research on Cancer (IARC), World Health Organization (WHO), Lyon.

Role: Principal Investigator, UiB.

Global incidences and trends of leukemia (2023-)

In this project, we aim to estimate the global, regional, and national burden and trends of leukemia by subtype and age. The work is carried out at the Cancer Surveillance Unit at the International Agency for Research on Cancer (IARC), World Health Organization (WHO), Lyon.

Role: Principal Investigator, UiB.

Cancer risk in families with children with birth defects (2017-) 

In this project, we take advantage of large population-based registries in four Nordic countries to explore the relationship between birth defects and cancer risk in more detail, and more extensively, than previously done. Whether birth defect(s) is associated with cancer risk in the affected individual and their families is important for the understanding of the etiology of specific cancers and could possibly allow for identification of individuals at elevated risk who would benefit from more regular follow-up or subsequent clinical intervention (Paper I, Paper II, and Paper III).

Role: Statistician 2017-2021, PhD student 2021-2024.

Past projects

Development of job-exposure-models for risk assessment of benzene exposure (2017-2023)

The primary objective is to develop task- and job-exposure models to estimate benzene exposure by inhalation among the five job categories assumed to have the highest exposure at oil and gas processing installations (Paper I, Paper II, and Paper III).

Role: Statistician. 

Perinatal characteristics and thyroid cancer risk in mothers and offspring: a Nordic registry linkage study (2018-2022)

A Nordic birth and cancer registry linkage study to prospectively evaluate the associations of pregnancy complications and other perinatal characteristics with subsequent risk of thyroid cancer in women (subproject 1) and their offspring (subproject 2).  We hypothesize that benign thyroid disorders during pregnancy, particularly hypothyroidism (underactive thyroid) and perinatal characteristics related to or a consequence of underactive thyroid (e.g., preterm birth, gestational hypertension/preeclampsia, gestational diabetes, placental abruption) and/or altered sex steroid hormones during pregnancy (e.g., extreme birth weight, preterm birth, twin pregnancy, low birth order, hyperemesis, gestational hypertension/preeclampsia, pre-pregnancy and pregnancy weight and weight gain) are associated with increased risk of thyroid cancer in both mothers and their offspring (Paper I, and Paper II). 

Role: Statistician. 

The COSMOS intervention for improving the quality of life in nursing home patients study  (2016-2019)

The COSMOS project (COmmunication, Systematic pain assessment and treatment, Medication review, Organization of activities, and Safety) is a multicenter, cluster-randomized controlled trial aimed to improve the quality of life in nursing home patients. 545 patients from 67 nursing home units from the eastern and western part of Norway were included in the study (Paper I, and Paper II).

Role: Statistician. 

The DEP.PAIN.DEM study - pain treatment and depression in nursing home patients (2016-2018)

The DEP.PAIN.DEM project is a multicentre, randomised, placebo controlled trial which aims to determine whether pain treatment reduces symptoms of depression in nursing home patients with dementia and depression. 165 patients from 47 nursing homes in different regions of Norway were included in the study (Paper I, Paper II, and Paper III).

Role: Statistician.
