Subject: Community detection is an essential tool in the analysis of complex networks, with diverse applications such as identifying genes related to cancer, uncovering terror cells on Twitter, and understanding links between politicians.
For the simplest case of networks, there has been an abundant body of research, and many effective algorithms have been designed. But for more complex networks, the field is much more sparsely populated, due to the lack of consensus surrounding the definition of a community.
The main focus of this PhD will be on unifying the problem of community detection in directed networks. It will build on a recent framework based on higher-order representations of networks, which has had some success. It will also build on existing work by the supervisors to produce methods tailored to the needs of the intelligence community.
The project will blend cutting edge tools for mathematical analysis with algorithm development and extensive investigation of applications.

all of whom will be followed by students presenting their talks. Each day we will kick off with a keynote speaker at 11am, followed by two student presentations, wrapping up at 1pm. To sign up to get links and more information or if you want to take the chance to present your work in a friendly environment, feel free to send us your title and abstract via the registration form.
Register now here or follow the link in the attached poster.
Deadline for conference registration: 3rd June
Deadline for student talk contributions: 24th May
The detailed program with titles and abstracts will be sent out after the deadline for contributions. In the meantime, if you have any questions feel free to contact us at: SIAMreading@outlook.com
Many thanks,

We welcome applications to fill a postdoctoral position on statistical data processing in assisted living technologies from candidates with
scientific computing, applied mathematics or computational statistics background. The post entails primarily independent research work but also some collaboration with other researchers from the NewTechnologies of Care Centre (https://www.ed.ac.uk/usher/advanced-care-research-centre). You will contribute to the research, analysis and development of randomised sketching algorithms
for streaming sensor data in the context of online model learning. The goal of the project is to identify structure in streaming data from
various sensors and capture it in a “data sketch”, a low-dimensional structure that preserves the main features of the original data with
respect to a given computational task.
Deadline: 31st of May.
The initial appointment is for 18 months extension subject to performance.

IR Tools is a MATLAB Package of Iterative Regularization Methods and Test Problems for Linear Inverse Problems, which was first released in Summer 2018.
The University of Bath is hosting a virtual IR Tools training event, aimed at postgraduate students and researchers who would like to learn more about IR Tools and its usage, as well as understand the theory underlying linear inverse problem solvers and get some hands-on experiences in dealing with large-scale discrete inverse problems. Here are a few details:
To register your interest in attending the event, please fill in and submit this questionnaire: https://docs.google.com/forms/d/e/1FAIpQLSfdlWAkOap-c7Go62CXHqNwDrsQal7tvOpaNtogs7vR0WWIig/viewform?usp=sf_link. Deadline for applications: 05/05/2021.
You can learn more about IR Tools by visiting the page: http://people.compute.dtu.dk/pcha/IRtools/. IR Tools is available through github: https://github.com/jnagy1/IRtools.
Topics to be addressed during the event include: introduction to regularization methods and why do we need them, the singular value decomposition of a matrix as a tool for analyzing linear inverse problems, popular spectral filtetring methods, popular iterative regularization methods for linear systems, strategies for handling nonlinear structured inverse problems, applications to inverse problems in computed tomography.
If you would like more information about the event or if you have any questions, please send an email to S.Gazzola@bath.ac.uk.
The SIAM-IMA Student Chapters of Strathclyde, Manchester, Cardiff, and Dublin successfully hosted a virtual networking event for PhD students on the 9th of December 2020. The event consisted of a careers talk given jointly by Dr. Ben Tordoff and Dr. Oli Tissot from MathWorks, followed by a team table quiz with approximately 40-50 attendees from the four Universities.
The careers talk gave a brief history of MathWorks and MATLAB and described the problems that they solve and how their customers make the world a better place using the tools that they build. The presentation also gave an insight into how the skills and knowledge gained during a PhD can then be transferred and utilized in industry. If you wish to find out more about MathWorks, then we recommend consulting the blog by the cofounder of MathWorks Cleve Moler, namely Cleve’s Corner – https://blogs.mathworks.com/cleve/, or the blog Behind the Headlines – https://blogs.mathworks.com/headlines/.
The table quiz afterwards was hosted by four committee members, one from each University, and gave students a chance to meet and socialize in an informal setting.
We have all missed the ability to attend events face-to-face during the Covid-19 pandemic. However, we hope that the increase in virtual seminars, conferences and networking throughout this time will continue to facilitate collaborative events in the future.

The Irish Numerical Analysis Forum (INAF) is a new initiative where experts from various countries give talks on their subject areas that are suitable for a **general numerical analysis audience** — not just those who already have some familiarity with the topic of the talk.
The series starts on 21-Jan-2021; more info, including a list of the first 6 speakers and instructions for registering your name and email address, are given at the INAF website at https://staff.ul.ie/natalia/inaf
The talks will be streamed online via zoom and are free to view; one must however register in advance with INAF to gain access to them. We will usually have one talk every two weeks, but the talk timetable may vary from this. A registration puts you on our mailing list for receiving zoom links for all talks.
The SIAM-UKIE Annual e-Meeting 2021 will take place on zoom on Friday the 8th of January 2021, 2PM-3:30PM.
Registration is now open at this link.
The meeting will consist of a talk by Prof. James Gleeson (University of Limerick) followed by the Section business meeting. Title and abstract of the talk are detailed below.
Title: Branching processes as models of cascade dynamics on networks
Presenter: Prof James Gleeson, University of Limerick, Ireland
Abstract: Network models may be applied to describe many complex systems, and in the era of online social networks the study of dynamics on networks is an important branch of computational social science. Cascade dynamics can occur when the state of a node is affected by the states of its neighbours in the network, for example when a Twitter user is inspired to retweet a message that she received from a user she follows, with one event (the retweet) potentially causing further events (retweets by followers of followers) in a chain reaction. In this talk I will review some mathematical models that can help us understand how social contagion (the spread of cultural fads and the viral diffusion of information) depends upon the structure of the social network and on the dynamics of human behaviour. Although the models are simple enough to allow for mathematical analysis, I will show examples where they can also provide good matches to empirical observations of cascades on social networks.
