DTU Compute would like to invite applications for a 3-year PhD position with earliest possible starting date September 1, 2020 (starting time negotiable). The position is financed by the DFF project “Learning the Structure and Dynamics of Complex Networks” and the PhD will be supervised by Professor Morten Mørup and Professor Sune Lehmann at the Section for Cognitive Systems, DTU Compute.

The project will develop novel computational frameworks for the analysis of dynamic social networks. In particular, the project will significantly advance upon the modeling of dynamic networks by enhancing considerably the ability to analyze massive networks through dynamic embeddings. The tools developed will allow us to visualize dynamic network structure, and forecast future interactions between entities. The project will exploit stochastic large-scale optimization frameworks and parallel computations using PyTorch/TensorFlow and derive efficient statistical machine learning modeling tools for large dynamic network analyses. The tools developed will be general and extended from linear to non-linear dynamic modeling using deep learning sequence modeling approaches. The project will further develop a predictive engine in which the learned models can be used efficiently to forecast future time-steps.

 

The developed dynamic network analysis tools will be used to analyze imminent challenges within our digital society enabling us to describe the dynamics of knowledge production, predict information propagation, and spot filter bubbles. The project comprises an interdisciplinary team of researchers with the necessary competences within machine learning and social network analysis. The project includes a research stay 3-6 month at project collaborator Professor Martin Rosvall (MR) at Umeå University who is an expert in statistical modeling of networks using information theoretic compression and key developer of important network modeling tools including InfoMap (mapequation.org)

Qualifications
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. 

You must have a master’s degree in engineering science or natural science or equivalent academic qualifications. You must have a very strong background within machine learning and programming in Python. Experience in time-series analysis and complex network modeling is an advantage. You must be fluent in English, both speaking and writing and possess excellent communication skills. 

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the 
DTU PhD Guide

Assessment
The assessment of the applicants will be made by Professor Morten Mørup and Professor Sune Lehmann (DTU Compute).
