23-24 June 2022, Edinburgh
The Edinburgh SIAM Student Chapter is proud to host the SIAM UKIE National Student Chapter Conference in 2022. The conference will be a two-day event, on Thursday 23rd and Friday 24th June, consisting of 3 plenary talks, contributed talks by students, and a poster session.
The conference will be held in hibrid format, at the University of Edinburgh's George Square campus..
We are pleased to announce the following plenary speakers:

Frailty Variation in Population Dynamics: Adventures and Disadventures of an Elusive Concept
Selection acting on unmeasured individual variation is a common source of bias in the analysis of populations. It has been shown to affect measured rates of mortality, the survival of endangered species, the scope of neutral theories of biodiversity and molecular evolution, measured risks of diseases whether non-communicable or infectious, the efficacy of interventions such as vaccines or symbionts, and it may be an underappreciated cause for the reproducibility crisis that the life and social sciences currently travers.
Forms of variation that respond to selection and impact population dynamics, termed frailty variation in demography, remain elusive in many disciplines. I will present some examples, including how this appears to have affected the course of the coronavirus disease (COVID-19) pandemic.

Multilevel Optimization: Basics, an Application to the European Gas Market, and an Open Research Problem
In this talk, we will give an introduction to the field of multilevel optimization. To this end, we first focus on bilevel optimization problems and study their main properties. By doing so, we will see why this class of problems are very important for practice but we will also see why they are very challenging - both from a theoretical and from a practical point of view. Afterward, we discuss a recent application of multilevel optimization to model the European gas market as well as present and discuss some exemplary results for real-world data. Finally, we will illustrate how practical models need to be extended to cover uncertain aspects as well. This leads to a rather novel class of bilevel optimization problems for which we pose the open research question on whether they can be solved on a computer anyway.

The Path Towards Experimentation by Simulation… is Paved with Surrogate Models
Digital twin can be defined as a composable virtual representation of a system that can span its life cycle, is continuously updated from design and operational data, and can use simulation, machine learning, and reasoning to augment decision-making and / or control the system. Recent advances in computational workflows, physics-based solvers, big data processing and management tools bring the promise of digital twins and their impact on society closer to reality. One important enabling technology is surrogate modelling. The basic idea in the surrogate model approach is to invest resources in developing fast mathematical approximations to the long running computer codes or expensive physical experiments. Given these approximations, many questions can be posed and answered, many trade-offs explored, and insights gained. In this presentation, I will discuss different types of surrogate models and how they can be utilised advantageously in digital twin framework. I will focus on two areas: uncertainty quantification and system prediction for industrial applications.
Registration for conference attendance is closed.
Limited travel awards will be available. These include funds reserved for SIAM student chapter committee members and participants from under-represented groups.
