Early Prediction of Sepsis from Clinical Data - Oxford Mathematicians win the PhysioNet Computing in Cardiology Challenge 2019

Sepsis is a life-threatening condition caused by the body’s response to an infection. In the US alone, there are over 970,000 reported cases of sepsis each year accounting for between 6-30% of all Intensive Care Unit (ICU) admissions and over 50% of hospital deaths. It has been reported that in cases of septic shock, the risk of dying increases by approximately 10% for every hour of delay in receiving antibiotics. Early detection of sepsis events is essential in improving sepsis management and mortality rates in the ICU.

Since 2000, PhysioNet has hosted an annual challenge on clinically important problems involving data, whereby participants are invited to submit solutions that are run and scored on hidden test sets to give overall rankings. This year’s challenge was the “Early prediction of Sepsis from Clinical data.”
A team from Oxford Mathematics and Oxford Psychiatry which consisted of James Morrill, Andrey Kormilitzin, Alejo Nevado-Holgado, Sam Howison, and Terry Lyons ranked in first place out of 105 entries. The team built a method based on feature extraction using the Signature method. They showed how the model predictions could be used to provide an early warning system for high risk patients who can be given additional treatment or subject to closer monitoring.

Their work was made possible by support from the The Engineering and Physical Sciences Research Council (EPSRC) and the Alan Turing Institute.

Sam Cohen appointed to lead Public Engagement with Research for Oxford Mathematics

Oxford Mathematics is delighted to announce that Professor Sam Cohen has been chosen as one of seven Public Engagement with Research Leaders in the University of Oxford.

Mathematical research is an integral part of all our lives, though many people are blissfully unaware of the connection. Sam's role will be to encourage colleagues to explain that connection and to find smart and entertaining ways for them to do it, building on our mix of Public Lectures, Research Case-studies and social media.

Sam's own research is in stochastic analysis and mathematical finance. Beyond mathematics, he has interests in philosophy and Christian theology. Watch this space.

Oxford Mathematicians win teaching and equality and diversity awards

Oxford Mathematics is part of the Mathematical, Physical and Life Sciences Division (MPLS) here in Oxford and every year the division gives teaching and equality and diversity awards in recognition of the fact that teaching and the learning environment are at the very core of what we are about and from where all future success will derive.

This year Oxford Mathematicians were successful in various ways. In the teaching category Mareli Grady (who splits her time with the Department of Statistics) won for raising awareness of mathematics and engagement with the public through the Oxford Maths Festival; while Ian Griffiths, Sam Cohen and Frances Kirwan were recognised for their work on Fridays@4, an initiative which since 2015-16 has enhanced graduate students' study skills and their long-term educational development, and helped integrate students within the department.

Under the equality and diversity heading the Outstanding Contribution by a Staff Member – Student Choice Award is made to an individual (academic, researcher or administrator), nominated by a student or group of students, who has made an important contribution to advancing equality and diversity. Dominic Vella from Oxford Mathematics was nominated for creating and fostering a diverse and inclusive research group, with people from many different countries, socio-economic and educational backgrounds, and varying ethnic, gender and age profile.

Siddharth Arora and colleagues win Martin Black Prize for 2019 from the Institute of Physics and Engineering in Medicine

The Institute of Physics and Engineering in Medicine has announced the winners of the Martin Black Prize for 2019, which is awarded for the best paper published in Physiological Measurement.

The winner was 'Big data in Parkinson’s disease: using smartphones to remotely detect longitudinal disease phenotypes’ by Oxford Mathematician Siddharth Arora and John Prince and Maarten de Vos from Oxford's Institute of Biomedical Engineering and Department of Engineering Science respectively.

The paper's objective was to better understand the longitudinal characteristics of Parkinson’s disease through the analysis of finger tapping and memory tests collected remotely using smartphones. More on Siddharth's work can be found here.

Oxford Mathematics trio scoop LMS Prizes

Three Oxford Mathematicians have been awarded 2019 London Mathematical Society (LMS) Prizes.

Andrew Wiles has been awarded a De Morgan Medal for his seminal contributions to number theory and for his resolution of ‘Fermat’s Last Theorem’ in particular, as well as for his numerous activities promoting mathematics in general.

Ben Green has been awarded a Senior Whitehead Prize for his groundbreaking results in additive combinatorics, analytic number theory and group theory.

David Conlon has been awarded a Whitehead Prize in recognition of his many contributions to combinatorics. His particular expertise is Ramsey Theory, where he has made fundamental contributions to both the arithmetic and graph-theoretic sides of the subject.

Matthew Butler awarded the Lighthill-Thwaites Prize for 2019

Oxford Mathematician Matthew Butler has been awarded the biennial Lighthill-Thwaites Prize for 2019. The prize is awarded by the Institute of Mathematics and its Applications to researchers who have spent no more than five years in full-time study or work since completing their undergraduate degrees.

Matthew's research focuses on fluid dynamics, particulary flows at low Reynolds number involving surface tension and interactions with elastic boundaries. His talk at the British Applied Mathematics Colloquium 2019 where the prize was awarded was entitled 'Sticking with droplets: Insect-inspired modelling of capillary adhesion" and focused on how having a deformable foot can be beneficial when trying to adhere to a substrate using the surface tension of a fluid droplet. In his PhD Matthew is studying insect adhesion, and in particular how insects can utilise physical laws to improve their ability to stick to surfaces.

Oxford Mathematician Doireann O'Kiely won the prize in 2017 and Laura Kimpton, also from Oxford, won it in 2013. Oxford Mathematician Jessica Williams was also a finalist this year.

Artur Ekert awarded a Micius Quantum Prize 2019

Oxford Mathematician Artur Ekert has been awarded a Micius Quantum Prize 2019 (Theory category) for his invention of entanglement-based quantum key distribution, entanglement swapping, and entanglement purification. The prizes recognise the scientists who have made outstanding contributions in the field of quantum mechanics and the 2019 prizes focus on the field of quantum communication. 

Artur Ekert is one of the leaders in the Quantum Cryptography field. His research extends over most aspects of information processing in quantum-mechanical systems and brings together theoretical and experimental quantum physics, computer science and information theory. Its scope ranges from deep fundamental issues in physics to prospective commercial exploitation by the computing and communications industries.

Oxford Physicist and close colleague of Artur's, David Deutsch was also awarded a prize in the Quantum Computation Theory Category.

The Micius prizes are awarded by the Micius Quantum Foundation. The Foundation is named after Micius, a Chinese philosopher who lived in the fifth century BC.
