London Hopper is for academic researchers across the UK who are building a career in computing.
About this Event
UCL and BCS Academy will be presenting the 14th London Hopper Colloquium on Wednesday 28 October 2020. London Hopper is for academic researchers across the UK who are building a career in computing. Featuring women speakers talking about their research, a spotlight competition open to postgraduate students, and opportunities to network with other new researchers in computing, this year’s event will be held online, via Go To Webinar. We will hear from women about their work on logic, quantum theory and digital music.
For questions please contact firstname.lastname@example.org.
*Please note that London Hopper uses an inclusive definition of “woman” and “female”, which means all individuals who identify fully or partly as women. We also welcome non-binary people to attend and present, and everyone is welcome to attend as an audience member.
The Research Spotlight competition focuses on women research Masters and PhD students, providing them with a friendly forum for communicating the essence of their work. This will be via 3-5 minutes (depending on the number of accepted submissions) recorded presentations, broadcasted during Hopper 2020. Presentation topics may be from any research area within the field of computing, and may encompass interdisciplinary studies connected to computing. There will be 10-12 spotlight presentations, split between two thirty-minute sessions. Prizes will be awarded for the best research spotlight presentations and each entrant will also receive a prize.
If you would like to apply for the research spotlight competition, please first register for London Hopper 2020. You will receive details on how to submit your abstract within your Eventbrite confirmation email.

Titles and abstracts
Sharon Moore MBE
When is Innovation not Innovation? How to make sure great tech gets great results.
Abstract: AI, machine learning, blockchain, IoT... how often do feel tempted to play tech buzzword bingo at conferences like these? We can do some magnificent things with tech, that will make a real difference but is everything we try innovation? In this session Sharon will share examples of the potential for technology - particularly within the public sector - and explore how to make sure it gets results for everyone.
New Ways of Thinking about Search with New Devices
Abstract: With the introduction of new types of devices in our everyday lives (e.g. smart phones, smart watches, smart glasses, etc.), the interfaces over which IR systems are used are becoming increasingly smaller, which limits the interactions users may have. Searching over devices with such small interfaces is not easy as it requires more effort to type and interact with such systems. Hence, building IR systems that can reduce the interactions needed with the device is highly critical.
Design, optimisation and evaluation of retrieval systems has traditionally focused on identifying and retrieving documents relevant to a query submitted by the user. However, with the new devices over which search engines are used for, effort to find relevant information plays a significant role for user satisfaction.
In this talk, I will first argue that effort to find relevant information in a document can have a significant impact on user satisfaction, arguing that more research should be put into devising retrieval methods that aim at minimising user effort, given a query. Ideally, a search engine should be able to understand the reason that caused the user to submit a query and it should help the user achieve the actual task by guiding her through the steps (or subtasks) that need to be completed.
Devising such task based information retrieval systems have several challenges that have to be tackled. In the second part of this talk, I will focus on the problems that need to be solved when designing such systems, as well as the progress that we have made in these areas.
Classical complexity of counting problems via quantum computing
Abstract: Quantum computing research looks at how to exploit effects from quantum physics to solve certain computational problems more efficiently than would otherwise be possible. (Classical) computational complexity aims to classify broad families of computational problems according to how difficult they are to solve on a classical, i.e. non-quantum, computer.
In this talk, I will show how knowledge from quantum computing is nevertheless very useful in determining the classical computational complexity of counting problems: computational problems that involve computing a weighted sum, such as the number of independent sets of some graph, or the total weight of independent sets where each set is weighted by its size.
Challenges and Opportunities in working with E-Textiles
Abstract: Electronic textiles (e-textiles) are conductive fabrics and threads that can be used to form circuitry which can be directly integrated into wearable garments or other soft furnishings like seat covers to facilitate wearable or ubiquitous computing.
This talk will present recent work showing how e-textile pressure and stretch sensors can perform tasks such as detecting body movement and even discriminating between social activities such as speaking and listening. However, there are still significant challenges in prototyping with this technology and moving it to manufacturing environments.
Inter- and trans-disciplinary expertise is required from a broad range of fields - from signal processing to clothing pattern cutting - in order to generate robust and reliable sensing systems.

The Hopper Colloquia
The London Hopper Colloquia grew out of the Scottish Hopper Colloquia, and are modelled on the American Grace Hopper Celebration of Women in Computing which is designed to bring the research and career interests of women in computing to the forefront. These annual American meetings are held as a tribute to Admiral Grace Murray Hopper pioneer of the computer business language COBOL - who inspired many young U.S. Naval computing students during her heyday and still continues to inspire computer scientists around the world many years after her death.
