BScHons, MSc, PhD
Teaching Fellow in ECS.
Taught modules include Professional Development, Data Visualisation and Data Mining.
After 11 years teaching English and Media in a big secondary school (including a sixth form) I decided to take a break and do something completely different. I completed the Web Science MOOC on Futurelearn, and from there completed a Masters and a PhD here at the the University of Southampton.
I'm now a Teaching Fellow here, based in the research group WAIS (Web and Internet Science).

There is plenty of research around Education and students; how students learn (in different key stages), online and blended learning, assessment etc. What is lacking is a focus on teachers: what they say, where they say it, the communities they form, the impact of online learning on their teaching practice; and how the Web has facilitated this.
My first major piece of research focused on how teachers use blogs: what they write, whether this has changed over time, and whether it's possible to see the impact of Education policy in the Edu-blogosphere. However, there is much useful conversation also happening on Twitter. Can these be linked? Can we add useful data, such as blog titles and tags to improve topic modelling, or classifier models? Couold we build a knowledge graph and create something that would be useful to the teaching community?

Research software engineers will use machine learning to explore polarisation and disengagement with politics as part of a new Future Leaders Fellowship at the University of Southampton.
The Rebooting Democracy project with Dr Matt Ryan is one of two new fellowships awarded to the Russell Group University by the UK Research and Innovation (UKRI) scheme.
Matt, a Lecturer in Governance and Public Policy, will work across three phases with the Southampton Research Software Group on the £1.197 million programme.
“Democracy is in trouble,” he explains. “Most people agree that democracy is a good thing, but there are issues with how it works in practice including declining trust in government and political parties, distorted digital communications, and rising polarisation and extremism in politics.”
Phase one will involve combining data from surveys, crowdsourcing and social media to determine conditions in the past that have led to increases in positive democratic behaviours.
The Research Software Group will then build a dashboard where social media data and machine learning are used to create an early warning system to tell governments and civil society groups what people are saying about various issues, or when issues are bubbling under that they should consult on.
For its third phase, the project will run trials using the information in the dashboard, working with partners such as Southampton City Council, Involve, and the World Bank, to make recommendations on what and how bodies should engage with the population.
“We have huge problems with democracy because people are polarising and the compromise that is essential to politics is becoming harder to reach,” Matt says. “How can we engage people in the right ways? How can we avoid violence, hate speech and so on?
“Brexit is a symptom of this – the discourse it’s created is much more polarised than before. There are many other examples in everyday life – issues such as climate change or intergenerational fairness create polarisation.”
Rebooting Democracy will recruit two post-doctoral researchers to advance the programme.
Professor Simon Hettrick, Co-Director of the Southampton Research Software Group, adds, “We are really excited about working with Matt on this important and highly topical project. Combining Matt’s expertise with our robust software engineering will produce a tool that allows vital insight into democratic processes.”
In Southampton’s second new Future Leaders Fellowship, Dr Christina Vanderwel will simulate wind patterns around buildings to assess their impact on the air quality of cities.
The project, which has been awarded £943,000, will print 3D scale models of suburban and urban landscapes, then inject dye into a water tunnel to observe how pollution spreads. The research will inform computer models that are used to determine the potential of buildings creating pollution hotspots.
The two fellowships are among around 70 to be awarded across the country. Earlier this year, Dr Sarah Lewthwaite won a Future Leaders Fellowship in the scheme’s first round for her research into digital accessibility education.

Two Artificial Intelligence students from the University of Southampton have won an International Automated Negotiating Agents Competition (ANAC) with an algorithmic strategy they fine-tuned during their degree.
Shaobo Xu and Peihao Ren developed the Agent GG software programme to autonomously negotiate the value of items such as apples and bananas by analysing up to thousands of rounds of data against rival participants.
The pair scooped first prize in the agent to agent league of the ANAC competition, held on August 15th at the International Joint Conference on AI (IJCAI) in Macau, China.
The success was one of two accolades for Southampton's School of Electronics and Computer Science at IJCAI 2019, with lecturer Dr Long Tran-Thanh delivering a prestigious Early Career Spotlight talk recognising his potential as a future leader in his field.
Southampton's expertise in computer vision, robotics and machine learning techniques has been delivered in over 10 years of teaching in its research-led MSc Artificial Intelligence programme. Shaobo and Peihao developed Agent GG as part of their Intelligent Agents module, with the creation finishing second in an in-class competition.
"We are excited to have ranked so highly in the competition and want to thank Module Lead Dr Enrico Gerding for all his support this past year," Peihao says. "We adapted our coursework according to the latest rules, adjusting just a few parameters, and we never expected our agent to outperform such impressive participants.
"Our agent assumes the opponent will always offer its best bid at first and then compromise, estimating the utility of a mid-point bid using both sides' best bids. Our method of compromising was key to our success, with offered bids always more favourable to our agent and the offers slowly compromised to the mid-point bid."
The Southampton students received €250 prize money, as well as a €750 scholarship from the organisers.
This summer's event was the 10th edition of the annual contest, with challengers divided into agent-agent, human-agent, supply chain management, diplomacy and werewolf leagues. Southampton students Meng Wan and Hui Cui finished second in last year's competition.
