She also holds a fulltime Professorship at the Global Health Institute at Antwerp University, and is Guest Professor at Ghent University (both in Belgium). She completed her training as a medical doctor (2008), PhD (2010), master in infection control/hospital hygiene (2010) and first post-doc at Ghent University in Belgium; and moved to Sweden in 2012 where she lived until summer 2020 after which she moved back to Belgium. She also obtained a master in Epidemiology from the London School of Hygiene and Tropical Medicine (by distance learning, 2015).
Nele has extensive experience in clinical, cancer, microbiome and pharmaco-epidemiology by working with the Swedish nationwide health registries, several clinical (microbiome) cohorts and systematic reviews and meta-analyses, resulting in over 120 peer-reviewed articles. Nele has supervised 6 PhD students (9 ongoing) and 24 master students successfully, and teaches on graduate and post-graduate level, mainly on study design, epidemiology, systematic reviews, meta-analyses, microbiome etc.
Although she has a broad interest and experience in different clinical topics (incl. infectious diseases) with many international collaborations; her main focus is to investigate the long-term effects of commonly prescribed drugs on female health and early childhood, cancer and diseases of the gastro-intestinal tract, through potential drug-mediated alterations of the microbiome. Her overall aim is to contribute to optimizing clinical practice and long-term health– for which trans-disciplinary approaches and collaborations are increasingly required.
Abstract – Population Variation of Microbiota
Technical advancements have accelerated microbiome research making it more affordable and feasible to perform large scale studies with thousands, or even hundreds of thousands of samples. Although size matters, proper study design remains crucial since humans and especially their microbiota are more diverse than a litter of new-born rodents or a series of patients. Where do we recruit our study participants? Who are they and how healthy are they? What do they eat, and which medications do they use? Which factors are affecting our microbiome compositions at different anatomical niches including our gastro-intestinal and reproductive tracts?
During this talk I will discuss what we already know about our microbiome during the different phases of life, in sickness and in health, and which scientific challenges still lie ahead. As an MD and clinical epidemiologist, I approach the microbiome field from a clinical and public health perspective – and how the microbiome can become useful as a tool in precision medicine, from prevention to diagnosis and treatment.

Abstract – Risk Prediction in Alzheimer Disease
Alzheimer disease (AD) is the leading cause of dementia with no clinically relevant disease-modifying cure. Biomarker, imaging and neuropsychological data obtained from presymptomatic carriers of rare mutations in exceptional autosomal dominant families suggest that the pathophysiological mechanisms of AD start years, if not decades, before the first symptoms. Accordingly, recent results of clinical trials suggest that AD prevention using antibodies targeting the main triggering factor of AD, i.e. Aβ peptide aggregation, might be efficient if delivered years after the first symptoms. Thus, predicting AD appears necessary to enable personalized AD prevention. Beyond rare autosomal dominant forms, AD is a complex disorder with a high genetic component. Deciphering the genetic determinants of AD etiology is hence necessary to detect individuals with a high risk. Large-scale case-control genetic studies recently identified a number of genes modulating AD risk. Among them, results from so-called rare variants identified in exome and genome sequencing data are associated with the highest levels of risk. I will present the genetic landscape of AD, from common variants to rare variants, and discuss on how we can build novel strategies to gather such heterogeneous information at the individual level, to make AD personalized prevention a reality in the future.

Maastricht University, Masstricht, NETHERLANDS
With a double degree in Medicine and Pharmacy, Harald Schmidt has a passion for network and systems medicine to re-define what we call “disease” from a descriptive symptom- and organ-based to a mechanism-based approach by using big data, innovative target validation, new mechanism-based diagnostics and rapid repurposing of registered drugs for new clinical applications by network pharmacology. He performs high risk/high potential gain research in areas of major medical need, such as the development and commercialisation of a first-in-class neuro-protective therapy in stroke, a therapy against a common and yet untreatable form of heart failure, and a therapy for resistant hypertension. He chaired the COST action OpenMultiMed on network and systems medicine, coordinates the H2020 project REPO-TRIAL on in-silico network pharmacology, leads the clinical work package in the H2020 programme FeatureCloud. From 2012-2017 he was awarded an ERC AdG, thereafter an ERC PoC grant. Together with Jan Baumbach he is co-editor-in-chief of the 2018 founded journal Systems Medicine and has founded the International Network Medicine Association (INMA.org). His multi-national (Germany, USA, Australia, Netherlands) research experience in Academia, Industry (Abbott) and Biotech (Vasopharm) has led to high impact publications (Hirsch 89) with high socio-economic relevance such as drug and diagnostics patents, spin-offs and patient benefit.
Abstract – The End of Medicine as we Know it
Existing drugs often fail to provide relevant benefit for most patients. The efficacy of the discovery of new drugs is low and in a constant decline predicting that pharma’s current approach may by the end of the 20’s no longer be financially sustainable. Also, why should we eternally need to discover new drugs. This poor translational success rate of biomedical research is due to lack of study quality and reproducibility and publication focus and bias. The most important reason, however, is our current concept of disease, i.e. mostly by organ or symptom, not by mechanism. Network Medicine will lead to a mechanism-based redefinition of disease, thereby enabling precision diagnosis and therapy. Due to drug repurposing this may eventually eliminate in many cases the need for drug discovery. Successful clinical drug repurposing will in turn also provide the necessary proof-of-concept for network medicine in general. If successful, we will need to reorganization of how we teach, train and practice medicine, moving from current organ-based disciplines, specializations and clinics and moving towards interdisciplinary board like structures. Examples of this new approach to disease include the redefinition of several cancers, immune diseases and a cluster of cerebro-cardio-metabolic phenotypes according their underlying molecular mechanism, including examples for drug repurposing and mechanism-based diagnostics. Importantly, a molecular disease mechanism is not a single protein, as currently often linked to common disease therapeutics, but always a signaling network. We observe however, that these networks in many cases differ from current signaling networks, which are rather mind maps of proteins assumed to function in a similar manner or use similar messengers. With respect to disease modules these networks are often smaller, overlap and thus lead to different drug repurposing decisions. Finally, since these mechanisms are networks, optimal therapy is a combination of drugs targeting several molecules within the same module in a synergistic manner. This allows low dosing and reduce the risk of any potential side effects. Finally, diagnostics are essential, in order to match patients that present both the phenotype and mechanotype and thus make therapies reach numbers needed to treat close to 1, i.e. that work in every patient. Since 80% of all proteins are present in all cells, the likelihood that a necessary pathway can be detected in (rare) circulating blood cells is proving a readily accessible platform to test module dysfunction, which we term the stimulome assay and which can also be considered an ex vivo efficacy test for the drugs to be clinically repurposed.

Abstract – Tissue engineering and 3D printing for regenerative therapy
Over the last decades, the fabrication of three-dimensional (3D) tissues has become commonplace. However, conventional 3D fabrication techniques are limited in their capacity to produce complex tissue constructs with the required precision and controllability that is needed to replicate biologically relevant tissues. To this end, 3D bioprinting offers great versatility in the fabrication of biomimetic volumetric tissues that are structurally and functionally relevant. It enables precise control of the composition, spatial distribution, and architecture of bioprinted constructs facilitating the recapitulation of the delicate shapes and structures of targeted organs and tissues. This talk will discuss our recent efforts in developing a series of advanced 3D bioprinting strategies along with various cytocompatible bioink formulations. These platform technologies are likely to provide new opportunities in constructing functional tissues to facilitate regeneration and microtissue models for promoting personalized medicine.
