Title: An update on seeing and touching molecules in motion through interactive molecular graphics

Speaker: Marc Baaden

Place: Lille Auditorium (208N2), 2rd floor Høyteknologisenteret

Time: Friday October 14th, 2016, from 10:15am to 11:00am


For several years now, our team pursues the goal to study complex molecular assemblies through interactive visualization, manipulation and analysis approaches to aid hypothesis generation and exploration of complex datasets. The UnityMol framework [1] forms a central tool for these investigations and is based on the Unity3D game engine. A first line of research tries to help with the 3D context, for instance through content-guided navigation, exploded views and semantic links between molecular objects and their analysis data [2]. Concerning the molecular representations, we extended the UnityMol repertoire to include specific visualizations for sugar molecules [3] and are now including coarse-grained systems by default. These are particularly apt for interactive simulations, even in the classroom or via crowdsourcing. A particular focus lies on the integration of dedicated hardware such as large, high-resolution display walls, or more recently head-mounted virtual reality headsets or augmented reality setups.

Title: Analyzing Complex Biomedical Data to Improve Patient Care

Speaker: Marc Vaudel

Place: Lille Auditorium (208N2), 2rd floor Høyteknologisenteret

Time: Friday September 30th, 2016, from 10:15am to 11:00am

High throughput sample characterization techniques like genomic sequencing have revolutionized modern patient care and led to the paradigms of personalized and precision medicine. However, comprehensive analytical approaches, the so-called omics fields, have also revealed the overwhelming complexity of biological systems, and require the interpretation of massive amounts of data. As a result, there is currently a major gap between what can be inferred from patient samples and what is actually used in the clinics. This presentation will introduce key concepts in using omics techniques for precision medicine, and underline some of the challenges associated with patient data interpretation. A particular emphasis will be given to the complexity of associating the omics data with disease mechanisms, and to the importance of making the results intelligible to all. Interactive data visualization plays a crucial role in this process, yet much remains to be done before patients can fully benefit from these modern approaches. Talents, ideas and expertise are much needed to overcome the challenges ahead. You are warmly invited to join the effort!

Title: Reproducibility in Visual Computing

Speaker: Paul Rosenthal

Place: Room 302O1 (former 3137), 3rd floor Høyteknologisenteret

Time: Friday August 12, 2016, from 10:15am to 11:00am

Reproducibility is the basis of all sciences. Without reproducibility, there is no advancement by building on previous knowledge and there can be no judgment of the reliability of current knowledge. As all fields of visual computing have matured, procedures for verifying and evaluating techniques have been introduced also in these field. While many individuals are making their code and procedures available, there are no established guidelines for reproducibility in the communities. However, introducing such practices would increase the acceptance of visual computing methods in other communities, make contributions more well-grounded, and expedite future innovation by making comparisons and improvements easier. In this talk, I will discuss this important role and the benefits of a strong culture of reproducibility. The explanations will be carried out with special focus on the fields of visualization, human-computer interaction, and computer graphics. Still, they can be transferred to other disciplines in many aspects and stimulate the respective discussion there.

Title: Perfusion modeling - The link between reservoir simulation and medical compartment modeling

Speaker: Erik Hanson

Place: Room 302O1 (former 3137), 3rd floor Høyteknologisenteret

Time: Friday May 27, 2016, from 10:15am to 11:00am

Perfusion, the amount of blood feeding a volume of tissue, has for decades been possible to measure using medical imaging techniques and simple mathematical models. The imaging technology and the mathematical and numerical tools needed to solve the models have evolved rapidly over this period. At the same time, the models themselves have not changed accordingly. In this talk we will se how methods for modeling of porous media flow may contribute to a better mathematical understanding of perfusion modeling. The pressure driven flow trough a capillary system is an essential concept both in perfusion and reservoir/porous media simulation. We will discuss how this link may contribute to an improved modeling framework suited to make use of the extensive amount of information accessible through modern 4D medical imaging.

Title: Untangling intracellular signaling network in cancer

Speaker: Bjørn Tore Gjertsen

Place: Room 302O1 (former 3137), 3rd floor Høyteknologisenteret

Time: Friday April 22, 2016, from 10:15am to 11:00am

Protein and gene networks centered on the regulatory tumor suppressor proteins may be of crucial importance both in carcinogenesis and in the response to chemotherapy. Tumor suppressor protein p53 integrates intracellular data in stress responses, receiving signals and translating these into differential gene expression. Interpretation of the data integrated on p53 may therefore reveal the response to therapy in cancer. Proteomics offers more specific data – closer to “the real action” – than the hitherto more frequently used gene expression profiling.
We are currently working with single cell immune profiles that include information about intracellular signaling systems. Patient cancer cells are sampled before and under therapy to determine response or therapy failure as early as possible, thereby adjusting therapy to the benefit of the patient. Data visualization tools have been imperative for our interpretation of measurements. The question open for discussion is if we need better data visualization tools to easy grasp the dynamics of cancer, and if we have these tools available for visualization with exponentially increasing data density.

Title: Seismic imaging and model building

Speaker: Ola Kristoffer Øye

Place: Room 3137, 3rd floor Høyteknologisenteret

Time: Friday March 18, 2016, from 10:15am to 11:00am

Seismic imaging is an important tool for understanding the subsurface in oil and gas exploration and production. Going from recorded seismic data to a high resolution seismic image requires several steps of data processing, model building and migration, often run through several iterations. In this talk I will cover some of the techniques involved in the seismic imaging pipeline, with focus on data driven model building and migration. I will cover how data and images can be analyzed in different domains, and discuss some of the challenges in producing high quality seismic images.

Title: Visualization, story telling, and the big picture.

Speaker: Rasmus Slaattelid

Place: Room 3137, 3rd floor Høyteknologisenteret

Time: Friday Febraury 19, 2016, from 10:15am to 11:00am

At the University of Bergen, there exists several research environments that focus on visualizations. Visualizations of data, or of scientific knowledge more generally, visual cultures, diagrammatic thinking, and story-telling in visual media. If we look beyond the UoB, the picture grows even more diverse. This multitude of approaches and interests already suggests that a comprehensive understanding of visualization as a cognitive tool within one discipline is difficult, and that more collaboration across these disciplinary divides would be fruitful. The aim of my talk is to present some possible common areas of interest between different disciplines studying visualizations.

Speaker: Rodica Mihai and Geir Nævdal

Place: Room 3137, 3rd floor Høyteknologisenteret

Time: Friday January 29, 2016, from 10:15am to 11:00am

IRIS has an extensive research activity within energy, social sciences and marine biology. Main areas for IRIS Energy are drilling and well technology, reservoir technology, green technologies and research testing facilities. We will give a short introduction to our work within real time modelling of the drilling process and name some of its challenges. Products of this work are among others, an unique simulation environment called Virtual Rig as well as automated drilling solutions which have been successfully implemented offshore. In the second part of the presentation we will introduce shortly our work on ensemble based methods for large scale parameter estimation and optimizations problems, with a particular focus on flow in porous media, namely oil reservoirs. Main research area in IRIS has been so far oil related but we have currently increasing ongoing research activity to apply similar techniques within other research areas such as medicine research, i.e. blood flow modelling
