We will meet on December 14, 2017 at 20:00 at the Brewery Tab for our annual Christmas Social. Please contact the secretary for tickets, which will also be on sale at our next events. Tickets will be £5 for members and non-members and cover some of the food during the evening. Drinks will be available for sale at the bar. A booking form is available in MSWord and PDF format.

We will hold our AGM on this day. The agenda will be announced soon. This will be followed by a short talk.
Blood circulation is of paramount importance. A healthy and intact vascular system is needed to ensure the proper functioning of cells, tissues and organs. One of the key concepts in vascular biology is angiogenesis, which is the growth of new blood vessels from pre-existing ones. This process is tightly controlled by the balance of pro-angiogenic (switch on) and anti-angiogenic (switch off) factors in the system. When this balance is disrupted, diseases can arise, such as cancer (where there is an oversupply of blood vessels) or diabetic foot ulcers (where there is an inadequate supply of blood vessels to support wound repairs). Therefore, an understanding of this pathophysiological process is particularly crucial as it will allow us to manipulate this angiogenic switch as a form of medical intervention, by which means it is hoped we will be able to treat these diseases in the future.
Koon Hwee Ang is originally from Singapore. He graduated from an double degree program in Biomedical Sciences and Traditional Chinese Medicine, which is a joint program between Nanyang Technological University (Singapore) and Beijing University of Chinese Medicine (China). During his internship in China, he became interested in the study of blood vessels and was later given the government-administered scholarship to pursue a DPhil in Medical Oncology at the University of Oxford, studying blood vessels in tumors. He is currently in his third year.

Since the 1990s there have been significant advances in our understanding of the ways in which volcanism interacts with Earth’s surface environment. This talk will explore some of these advances and explore the ways in which volcanism might have lead to long-term global change during geological history.
Tamsin Mather is a 
professor of Earth Science at the University of Oxford. Her main research interests center on the science behind volcanoes and volcanic behavior. My motivation is to understand volcanoes as (a) natural hazards, (b) a key planetary scale process throughout geological time, vital for maintaining habitability and (c) natural resources (e.g., geothermal power and the development of ore deposits).

Galaxies are huge clusters of hundreds of billions of stars – the Milky Way is our galaxy, itself just one of many billions more. But even these are diminutive compared with the sea in which they swim, dark matter, an unknown substance we cannot see with our telescopes because it doesn’t give off light.
Nonetheless, astronomers have developed several techniques to indirectly study dark matter. In this talk I will describe how powerful telescopes in Hawaii, Chile and South Africa help us look back in time over the history of the Universe to see how the creation and development of galaxies is linked to dark matter, hopefully helping us learn more about the galaxies we see today and potentially even something about the mysterious nature of dark matter itself.
I will discuss the current research being done in Oxford using the VISTA telescope in Chile, as well as what the future holds for cosmology and galaxy evolution, in particular the Square Kilometre Array, a radio telescope being built in South Africa, and the planned Euclid space telescope – each of which will observe billions of galaxies from the current day back to the beginning of time.
Peter is a postdoctoral researcher in the Physics Department at the University of Oxford working on problems in high energy density physic
s and astrophysics, working with Professor Steven Rose.
He completed his D.Phil. at Lincoln College, University of Oxford earlier this year working with Professor Matt Jarvis. Before this he completed a BA in Mathematics and a MSci in Astrophysics at Pembroke College, University of Cambridge. He has also spent time working on research projects in California and South Africa.
He is also Chair of the Student Advisory Board for the Institute for Research in Schools, a new UK-wide charitable foundation that supports secondary school students doing real scientific research.

Recent years has seen the explosion of Artificial Intelligence (AI)-based technologies, along with buzz words like “machine learning”, “computer vision” and “self-driving cars”.
These leaps and bounds can largely be attributed to the neural network, an algorithmic structure which takes inspiration from the human brain, a biological tissue which functions through the synchronous and asynchronous activity of networks of elementary units or neurons. In this talk I will step through how computer vision scientists are using neural networks to teach computers to automatically understand images and videos. The goal of my PhD, however, is not just to get a computer to understand images, but to enable it to converse with a human, and for this, the computer must also have a grasp of language.
I will demonstrate how neural networks are being used to parse questions and produce meaningful and correct answers based on the images that the computer “sees”. My ultimate application is to use these advances to develop a smart AI-based chatbot with computer vision “eyes” that will make the lives of visually-impaired people easier: from navigating them around cities and new environments, to guiding them around their homes, helping them make a cup of tea and engaging with them in some chit-chat.
Daniela is currently a D.Phil student in the Engineering Science
department and a graduate member of Pembroke College at the University of Oxford, United Kingdom. She is part of Torr Vision Group, under the joint supervision of Professor Philip Torr and Dr Stephen Hicks.
Prior to this, she completed a M.Sc in Neuroscience also at the University of Oxford, where she graduated with distinction. She obtained her undergraduate degree, a B.Sc in Electrical and Computer Engineering, at the University of Cape Town, South Africa.
Her current research interests include using vision and language models for semantic scene parsing, in particular toward developing visual prostheses to aid the visually-impaired.
