Zachary Chase shares Danny Lewin Best Student Paper Award 2021 from SIGACT

There are plenty of awards and prizes for senior mathematicians and scientists. But just as important, and maybe more so, are the awards for those just starting out.

SIGACT (Special Interest Group on Algorithms and Computation Theory) is an international organisation that fosters and promotes the discovery and dissemination of high quality research in theoretical computer science. The Danny Lewin Best Student Paper award is presented by SIGACT each year at the ACM Symposium on Theory of Computing.

Oxford DPhil Mathematician Zachary's winning paper is entitled “Separating Words and Trace Reconstruction.” A deterministic finite automaton is one of the most basic computational models in theoretical computer science. Telling two strings apart is one of the most basic computational tasks. In this paper, progress is made on an old problem of how efficiently one can tell two strings apart with a deterministic finite automaton. The proof methods surprisingly involve complex analysis and connections to other fundamental problems.

The 2021 SIGACT Symposium will take place online from 21-25 June.

Oxford Mathematics Open Days 24th April and 1 May

Study Maths & describe the world.

Mathematics underpins so much of our understanding of our world, whether it be its close relationship with the other Life Sciences or its wider influence on such things as how cities grow or how social media networks operate.

At Oxford Mathematics Open Days you'll get a real sense of where a maths degree can take you. Indeed, as well as Maths you may also want to consider our joint schools in Maths and Statistics, Maths and Computer Science and Maths and Philosophy.

These events will be online-only, with live broadcasts, pre-recorded content, and question-and-answer sessions with our tutors and current students. No registration is necessary.

Bernadette Stolz awarded the 2021 Anile-ECMI Prize

The Anile-ECMI Prize is given to a young researcher for an excellent PhD thesis in industrial mathematics successfully submitted at a European university. It was established in honour of Professor Angelo Marcello Anile (1948-2007) of Catania, Italy and consists of a monetary prize of 2500 Euros and an invitation to give a talk at the ECMI 2021 conference on Wedneday 14 April.

In her DPhil (PhD), Bernadette investigated the use of topological data analysis for biological data. She developed methods to quantify the unique features of tumour blood vessel networks. Using persistent homology on experimental data from different imaging modalities, she validated known treatment effects on the networks and showed how the effects of radiation treatments alter the vascular structure.

In her thesis, Bernadette further applied persistent homology to functional networks from neuroscience experiments. To overcome computational challenges that are a major limitation in applications of persistent homology to real-world data, she researched the use of local computations of persistent homology and her results indicate that these can be used for outlier-robust subsampling from large and noisy data sets. In addition, she demonstrated that such computations can detect points located near geometric anomalies in data sampled from intersecting manifolds. This work has recently been published in Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Bernadette developed her research in close collaboration with Oxford Mathematicians Heather Harrington, Jared Tanner, Vidit Nanda, and Helen Byrne as well as Mason Porter (UCLA), biological collaborators from Oxford Radiation Oncology and industrial researchers from Roche.

In her current postdoc at Oxford Mathematics' Centre for Topological Data Analysis, Bernadette is looking at applying persistent homology to quantify the output from mathematical models of angiogenesis.

The many faces and hands of Online Student Lectures

It is a cliche that crises create opportunities. But they certainly demand innovation (and a lot of hard work). In Oxford Mathematics, in line with many others departments and universities, we have had to switch from in-person teaching to online in most cases. This has been 100% the case in terms of undergraduate lectures which normally take place in large lecture theatres where a whiteboard, a marker pen (or two or three) and a mathematician take centre stage.

However, the online world is a much more varied place. Lectures tend to be shorter (though the courses are the same length), some lecturers write as they go using tablets while some use pre-prepared slides. Some are in shot, some are not. However, as you can see from the image above and the lecture below, some lecturers, in this case André Henriques (and also Artur Ekert in other lectures), are trying different approaches, taking advantage of latest technologies. The lightboard is not new, but this might be its teaching moment.

Then again, the important thing is that the teaching is up to scratch. You can judge for yourself via the lecture below. You can also watch a range of student lectures on our YouTube channel as we show what we do and the increasing variety of ways we do it.

The Oxford SIAM Student Chapter 3 Minute Thesis Competition

Postgraduate students are mathematics' future. 

The Oxford University Society for Industrial and Applied Mathematics Student Chapter 3 Minute Thesis Competition saw 10 of our postgraduates present their latest research to a panel of our judges. Topics included Langland's Grand Unified Theory; Quantum irreversibility; and using magnets and maths to deliver stem cell therapy.

You can watch the competition via the video below.

One Term in 5 Minutes

To gain an insight in to mathematical student life under lockdown, we asked Oxford Mathematics and St Peter's College 2nd Year Undergraduate Matt Antrobus to provide us with one-minute updates over the course of last term.

So he did in a very personable and honest way, describing the maths he is doing, how he is doing it and how much work is involved. Matt also reflects on the stark fact that over half his time in Oxford has been under the cloud of Covid.

You can watch all five films by scrolling through our Twitter, Facebook or Instagram pages.

Round up: the Oxford Mathematics Annual Newsletter

Round up, the Oxford Mathematics Annual Newsletter, is a calculated attempt to describe our lives, mathematical and non-mathematical, over the past 12 months. From a summary of some of our research into the Coronavirus to a moving tribute to Peter Neumann by Martin Bridson, via articles on diversity, fantasy football and of course our Nobel Prize winner (pictured), it throws a little light, we hope, on what we did during the year that was 2020.

The Newsletter goes out to over 12,000 Oxford Mathematics alumni around the world and to anyone else who may be interested of course. Arguably the most expressive part of the Newsletter is a wordless photo montage. Why not have a look?

Geometry of Surfaces - 4 more Oxford Mathematics Student Lectures

Our 'Fantastic Voyage' through Oxford Mathematics Student Lectures brings us to four 3rd Year lectures by Dominic Joyce on Topological Surfaces. These lectures are shown pretty much as they are seen by the students (they use a different platform with a few more features but the lectures are the same) as we all get to grips with the online world. Lectures on Linear Algebra, Integral transforms, Networks, Set Theory, Maths History and much more will be shown over the next few weeks.

Below is the fourth lecture of the course, but you can watch all four of Dominic's lectures via the Playlist as well as over 30 other student lectures on the YouTube Channel.

Incidentally 'Fantastic Voyage' is a classic bit of 60s sci-fi about a submarine crew who are shrunk to microscopic size and venture into the body of an injured scientist to repair damage to his brain. It's a tenous link but we like it so, if you are interested, check it out.

Oxford Mathematics Public Lecture. From one extreme to another: the statistics of extreme events - Jon Keating

Oxford Mathematics Public Lecture
Tuesday 16 March 2021
5.00-6.00pm

Jon Keating will discuss the statistics of rare, extreme events in various contexts, including: evaluating performance at the Olympics; explaining how glasses freeze; illustrating why computers are more effective than expected at learning; and understanding the Riemann zeta-function, the mathematical object that encodes the mysterious distribution of the prime numbers. 

Jon Keating is Sedleian Professor of Natural Philosophy in the University of Oxford and a Fellow of The Queen's College.
