Abstract

Our world is 3D and so is the patient. But visual camera observations are 2D. Advancements in digital imaging now enable capturing rich 3D information of our surrounding, transforming our ability to digitally perceive, present, and analyze data. By combining multiple data sources or frames in a video, we can create context-enhanced digital copies of the physical world as well as the patient - and apply data-driven interpretations and processing. Data sources reach from ceiling mounted cameras in the OR to endoscopic images or robot-mounted sensors. In this talk, we want to look into underlying core ideas of example 3D computer vision pipelines and investigate how these approaches can be used in clinical applications. As a basis for a discussion at this exciting interdisciplinary crossroad, we dive into the subtopics 3D digital reconstruction, data curation for XR, and robot-assisted surgery.

Abstract

Due to the rapid progress in developing experimental techniques, establishing and improving analysis methods is one of the major challenges in computational life sciences. For many analysis tasks, however, the limitations and performance of competing methods remain unknown, and there are no clear rules or guidelines for selecting the optimal analysis method. Benchmark studies have proven to be valuable tools for evaluating the performance and applicability of analysis approaches. However, they are often subject to methodological limitations and deficiencies, leading to potential bias in the results.

In my presentation, I will give an overview of novel approaches developed in my group in the context of mathematical modeling and omics analyses. In particular, I will summarize our ongoing efforts to improve the methodology of benchmark studies. By generally incorporating rigorous planning, design, and analysis principles in benchmark studies, we aim to promote the development of novel analysis approaches and the identification of decision rules for optimal method selection in practice. Especially in view of the enormous efforts to apply deep learning methods in all areas of research, reliable performance comparisons are of great importance.

Abstract

The primary aim of this talk to develop and apply biostatistical methods to improve predictive modeling of data for precision medicine. In order to achieve such a solid framework for different type of datasets the selection of methods are important. However, currently their is no universal method which can be applied for data gathered from humans. To understand the given data at hand, first statistical tools which considers the distribution of the data namely Bayesian posterior distribution will be discussed. Second, to counter one of the most important problems in most of the clinical datasets is the demographics namely matching cohorts for sex would be considered with propensity score matching analyses. In order to model complex datasets, with several input and output variables the structural equation modelling will be delibrated. After understanding and modelling the datasets the prediction will be covered with some machine and deep learning approaches and finally some applications to datasets from multimodal, longitudinal and signal based analyses will be explored. For each methodological aspect an example will be provided with obtained results.  The applications will be highlighted with examples and corresponding results. Taken together, the integration of methods leading to the individualized prediction of each subject will be demonstrated.

Abstract

Epigenetics, which involves heritable changes in gene expression without DNA sequence alterations, plays a crucial role in tumour classification, with DNA methylation serving as a key biomarker. Tumour classification based on DNA methylation patterns has emerged as a pivotal approach in precision diagnostics, offering insights into cell-of-origin as well as tumour progression. This talk will explore the evolution of methylation-based classifiers, with a focus on CNS tumours, and highlight recent advances in using methylation profiling to achieve accurate and scalable diagnostics. Additionally, the talk will introduce development and application of novel technologies like nanopore sequencing and AI-based computational histopathology to improve accessibility of cutting-edge molecular diagnostics.

Abstract

Bioimpedance analysis is an established non-invasive method that is already in clinical use for body composition measurement or electrical impedance tomography. However, novel instrumentation and signal processing approaches enable significant improvements of these applications as well as new measurement approaches. This presentation will give a brief insight into the theory of bioimpedance analysis and discuss instrumentation approaches. Subsequently, examples of new scientific measurement approaches will be presented. The focus will be on the detection of skeletal muscle contractions (impedance myography) and pulse wave detection (impedance plethysmography).

Abstract

Wearables have been the dominant consumer monitoring device for the past decades, however, not the ideal one. Battery dependency, correct placement, good contact with skin, etc., all impose requirements and restrictions that can’t be met by everyone (e.g., vulnerable populations, skin conditions, etc.). In light of this and in accordance with the ultimate idea of ubiquitous computing, the interaction between the user and sensor should be minimized or ideally removed entirely. This is being achieved with improvements and availability of sensors – namely RGB cameras, thermal cameras, radars, LIDARs, and others – accompanied by immense development of machine learning, specifically deep neural networks. In this talk we will overview existing methods for unobtrusive contact-free monitoring of physiological parameters and some psychological states that can be derived from them.
