Stillingstittel:
PhD and PostDoctoral positions in Machine Learning and Data Mining for Personalized Cancer Screening

Stillingsbeskrivelse:

We advertise two three-year doctoral positions and one two-year postdoctoral fellow position in machine learning and data mining for personalized cancer screening at SimulaMet and Cancer Registry of Norway, Oslo, Norway. The positions are available as a part of the Norwegian-funded research project DeCipher in collaboration between SimulaMet, Cancer Registry of Norway, Lawrence Livermore National Laboratory (LLNL), and Karolinska University Hospital. The project combines the unique Norwegian and Swedish registry data including extensive screening histories and epidemiological expertise, with LLNL's exceptional HPC computing infrastructure, data analysis and modelling experience, and with Simula's expertise in machine learning methodology.

Project Description

Cancer is a major cause of morbidity and mortality worldwide. A large proportion of these incidents are preventable. For example, a mass-screening program against cervical cancer established in the Nordic countries has demonstrated a reduction in morbidity and mortality almost by 80%. Despite this success, it remains a major challenge to improve the screening program, such as minimize overscreening and undertreatment, and hence reduce expenditure in a broad public health perspective.

Current knowledge about the disease together with a wealth of available data and modern technologies can offer far better personalized prevention, by deriving an individual-based time till the next screening.

By intelligent use of existing registries and health data, the DeCipher project aims to develop a data-driven framework to provide a personalized time-varying risk assessment for cancer initiation and identify subgroups of individuals and factors leading to similar disease progression. Specifically, the following three sub-projects will be investigated:

1. Development of matrix factorization approaches for reconstruction of individualized disease trajectories from longitudinal screening data (PostDoc at SimulaMet)
2. Development of geometric deep learning framework for reconstruction of individualized disease trajectories from longitudinal screening data (PhD fellow at Cancer Registry)
3. Development of data fusion approaches based on matrix and tensor factorizations for joint analysis of longitudinal screening data and lifestyle information as well as other relevant health data (PhD fellow at SimulaMet)

The developed methods will be validated and tested on Norwegian and Swedish datasets. The DeCipher results will allow for improvement of individual's preventive cancer healthcare while reducing the cost of screening programs.

The successful candidates are expected to develop a set of machine learning and data mining approaches to unravel patterns in the cancer screening and health data and learn discriminating features. The successful candidates will enjoy an inspiring and resourceful environment, with the possibility of travelling to conferences, short- and long-term research visits to LLNL, and establishing new collaborations.
