HGS MathComp Curriculum & Events

Deep learning is fueling advances and breakthroughs in a dizzying array of data-intensive scientific fields. In this talk, I will highlight recent and ongoing work of our lab that leverages deep learning to push the limits of advanced microscopy.
A long-standing challenge in the life sciences is to visualize biological cells at high resolution and with high throughput. Single molecule localization microscopy (SMLM) is among the most powerful and widely used super-resolution imaging methods, but is typically very slow and low throughput. I will present ANNA-PALM, a computational technique based on deep learning that can reconstruct high resolution views from strongly under-sampled SMLM data and widefield images, enabling considerable speed-ups without any compromise on spatial resolution. I will also highlight Shareloc, an online platform to facilitate the sharing and reanalysis of SMLM data, and Imjoy, a computational platform dedicated to facilitating the uptake of state-of-the art deep learning methods in the biomedical research community.

The IWR Colloquium will be held as an in-person event at the Mathematikon. In addition it will be streamed via Zoom.
If your are planing to attend in person you have to follow the 3G-rule set (vaccinated, recovered, tested).

Many engineering applications require the numerical evaluation of time-harmonic wave propagation problems over a range of frequencies. The most used technique to discretize partial differential equations is the finite element method. Due to the oscillations of analytical solutions the finite element discretization often becomes computationally expensive.

Model order reduction methods provide reliable approximations of the solution at low computational cost. In particular, they allow very fast responses both for real-time and multi-query contexts.

This talk deals with novel model order reduction techniques tailored to time-harmonic wave problems relying only on a precomputed set of snapshots, they present great flexibility, since they allow the construction of a surrogate starting from snapshots obtained via black-box solvers (e.g., commercial software).

The method’s efficiency is investigated in several examples, including transmission-reflection and scattering problems. Especially in the context of optimal control problems, where standard numerical techniques are unfeasible, the employment of surrogate models is crucial.

IMPORTANT: in person meeting changed to ONLINE ONLY meeting

Large-scale optimization is a vibrant field with many ties to neighboring areas including analysis, numerical linear algebra, differential geometry, machine learning and partial differential equations. This presentation showcases these connections using past and ongoing projects in our recently established group "Scientific Computing and Optimization". I will also address open problems and future directions in the field and advertise opportunities for collaboration.

Spatial and temporal control of molecular phenomena is crucial to develop intelligent materials for applications ranging from sensing over catalysis to photonic computing. In this regard, stimuli-responsive molecules enable to influence structural and dynamic properties at the atomic level in a highly controlled manner by external stimuli such as light.

To transfer external inputs into functionality, a detailed understanding of both, the operation mechanism of the responsive species and their impact on the environment, is needed. In the presentation, I will give an overview of our activities on developing and applying theoretical methods to investigate the dynamics of stimuli-responsive systems at different time and length scales. By establishing an automated and first-principle based parametrization approach for interatomic potentials, investigations of equilibrium and out-of-equilibrium phenomena in responsive and functional materials are performed.

My presentation is divided in three parts, which cover our atomistic investigations on (i) responsive molecular species (e.g. molecular switches/machines), (ii) the dynamic intermolecular interplay during molecular aggregation and atomically precise restructuring and (iii) hierarchal and responsive architectures (e.g. phase change material and functionalized Metal-Organic Frameworks). By directly linking of our multi-scale simulations with experimental techniques, our work contributions to a rational development of responsive and functional materials.

Uncertainty quantification plays an important role in many engineering applications. In this talk we discuss some recent advancements in the approximation of high-dimensional functions appearing in this context. We provide new results for surrogate modeling and parameter estimation in cases where the uncertainty is described by a Gaussian random field. Additionally we address how the usage of neural networks to learn linear and nonlinear operators may help in solving such tasks, and what possible challenges might lie ahead.

- Socio-hydrology and water resources management
- Environmental contamination and remediation
- Sustainable technology for water purity
- Cryosphere dynamics

! REGISTRATION REQUIRED !

It’s not only the research topic itself. Many doctoral candidates also struggle managing all the different tasks relates to research, teaching and career development. Techniques and tools for time management provide help to develop a better structure for time management. One of these tools is a Gantt diagram that allows to plan long-term projects. Other tools will be introduced in the workshop. And there will be space to exchange on experiences and ideas.

We all have different networks - no matter whether we call them "network" or not. These networks provide support, advice and help in different fields. To better use and understand them it is crucial to be aware of the fact that the purpose influences the network itself. If our purpose (or aim or goal) remains unclear efficient networking is impossible. The workshop "Purposeful Networking" provides basic information on networking and gives space to clarify personal aims - to create a link between network and purpose.

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognise risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practise the basic concepts of project management – a prerequisite in industries and research institutions.
