PhD Position Dynamic Symptoms Networks
JOB DESCRIPTION
We are seeking a PhD candidate to work on an exciting research project in an interdisciplinary team. You will focus on the use of computational and mathematical methods to address the increasing challenge posed by ‘multi-morbidity’, both computationally and theoretically, in collaboration with a more medicine-oriented PhD candidate.
In 2018, 5.4 million Dutchmen suffered from multi-morbidity, defined as the co-occurrence of two or more diseases. Treating the individual diseases in isolation leads potentially to high burden of treatment, overtreatment, and unforeseen interactions between symptoms, medicines, and/or therapies. For this reason, health care in the presence of multiple diseases demands a different approach than the traditional disease-centered focus. Clinical models for adequate diagnosis, prognosis, and treatment in the context of multi-morbidity are currently lacking. Common epidemiological methods to model multi-morbidity do not suffice because they do not take into account dynamic interactions between diseases.
There is a growing consensus that the complexities underlying the onset of disease states of an individual cannot be unraveled by traditional, reductionistic methods alone. A shift in research paradigm to computational science, complex systems, network thinking, and multivariate analysis is therefore imperative to move this field forward. Taking steps towards a new paradigm may, eventually, enable the design of more effective treatments for a large group of people.
The ultimate vision of the to-be-developed paradigm shift in this project is to take domain experts’ knowledge, patients’ experience, scientific literature, and data as an input; summarize the statistical/causal relations between various (bio-)medical variates and disease outcomes into what we call dynamic symptom networks; and finally assess to what extent diagnosis, prognosis, and treatment design based on such symptom networks would improve health care beyond the state-of-the-art disease-centered practice.
What are you going to do
This PhD position is part of a larger Dutch research grant under ZonMw, consisting of two closely collaborating PhD students. This position will focus on the computational science and mathematical aspects. The second PhD position will focus more on the domain expertise and application of traditional epidemiological techniques.
From a technical standpoint, you will focus specifically on identifying as well as modeling (mathematical/computational) the dynamics of multi-morbidities. This will be done through extending the concept of disease networks (see for instance https://www.nature.com/articles/s41540-020-00143-9 for an accessible introduction). The first manner in which we plan to extend it is to enrich the statistical associations, used as part of the method, with multivariate information-theoretic measures, specifically the relatively novel concept of synergistic information (see for instance https://www.mdpi.com/1099-4300/19/2/85). The second manner is to extend the network concept to a multiplex network, due to integrating different types of studies into a single analysis. Finally, we will attempt to identify causal links and causally important nodes in the networks by existing techniques (see https://www.nature.com/articles/s41467-019-10105-3 and http://rsif.royalsocietypublishing.org/content/10/88/20130568). All of this is to be integrated in a set of methods and tools, which the domain experts in our project can apply to (other) datasets. During the development of the theory, methods, and tools, you are expected to closely collaborate with domain experts in order to ensure relevance and validity of your approach.
Chronologically, your project will start with data analysis, think tank sessions, and group model building sessions. This will inform the computational and mathematical framework to generate plausible models and simulations of symptom-symptom networks, symptom-disease networks, and their combinations and projections. This is to be used to simulate hypothetical scenarios of increasing multi-morbidity and then assess to what extent the traditional disease-centered remains effective, and/or whether a new paradigm is needed to remain effective in the multi-morbid regime. Finally, since it is unlikely that the existing data sets are sufficiently rich to uniquely identify (causal) symptom models, this project will also involve uncertainty quantification and determining what properties of hypothetical new data sets will be decisive in increasing modeling accuracy.
REQUIREMENTS
What do we require of you
For this position you need:
- an MSc in Complex Systems Science, Computational Science, Applied Mathematics, Applied Statistics, Statistical Physics, or related disciplines;
- experience in high-level programming language(s) such as Python;
- affinity towards and good knowledge of network science (graph theory). Preferably with experience in computational modeling of networks, network processes, network flow dynamics, and/or calculating various network topological features;
- to enjoys interacting with domain experts from different disciplines and tackling an interdisciplinary problem by internalizing and subsequently integrating qualitative knowledge into novel theory, computational models, and/or quantitative analyses;
- to be trained in computational modeling techniques, such as (ordinary) differential equations, Markov dynamics, or cellular automata, and is trained in simulation techniques, such as Monte Carlo sampling;
- to be trained in basic (multivariate) statistical analysis and/or information theory;
- to be familiar with the concept of uncertainty quantification, forward propagation of uncertainty in models;
- affinity towards contributing to a more holistic, data-driven, and multi-scale approach to managing human disease.
CONDITIONS OF EMPLOYMENT
Fixed-term contract: 18 months.
Our offer
A temporary contract for 38 hours per week for the duration of four years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of four years).
