Mon 3rd December – “Fungi: the good and the bad” – Dr Sietse Van der Linde, 

Fungi often receive a lot of bad press and are perceived as dangerous, poisonous and parasitic organisms killing trees in our forests. Although, the number of tree pathogens is on the rise, there are also scores of fungi that are beneficial for our forest trees. Trees actually depend on those beneficial fungi (so-called mycorrhiza), for nutrition, water and pest resistance and would not survive without them. In this talk I will discuss both ends of the spectrum and show examples of both beneficial and pathogenic fungi. I will show the influence of our environment on how forest fungi are spread over the landscape and how fungi can adapt to a changing environment. Pathogenic fungi are not always introduced via a natural pathway and I would like to show what we could all do to prevent unwanted fungi to take hold in our landscape.

Sietse works at Forest Research as a molecular biologist in the tree health diagnostic and advisory service. He studied biology (BSc, MSc) at Leiden University in the Netherlands after which he received a PhD at the University of Aberdeen in 2008 for his thesis on the conservation and ecology of stipitate hydnoid fungi. Sietse previously worked as a molecular fungal ecologist at RBG Kew, Imperial College London (2013-2017), the Botanical institute of Basel (Switzerland; 2009-2013) and the James Hutton Institute in Aberdeen (2004-2008).


Mon 7th Jan 2019. “Wireless Communications: Towards a Connected World of People and Things.” K. Satyanarayana

Wireless communication has evolved from pigeon-post to paging, voice calls, text messages, video calls – and now Internet everywhere. It has become the ubiquitous means of socializing, doing business and of entertainment. There are around 5 billion mobile phones in use through which we transmit around 60 terabytes of data every month. And yet, this is just the beginning – the future is even more exciting as we are moving from the internet-of-things to holographic video calls, which can conjure up the image of a person right in the room when we talk to them. However, one of the key issues of this technology, whether we have the capacity to accommodate all these users at a high quality-of-service. An obvious solution to circumvent this problem is to increase the bandwidth used. But we only have a limited bandwidth.

In this talk, I shall shed light on how to address this problem.

Satyanarayana (www.satyanarayana.xyz) received his B. Tech. degree in Electrical Engineering from the Indian Institute of Technology Madras, India, in 2014. During Jul’14-Aug’15, he worked as a research assistant at Indian Institute of Science, Bangalore. Currently, Satya is a research scholar in Wireless Communications at the University of Southampton in liaison with InterDigital Europe, London, UK. His research interests include millimeter wave communications, hybrid beamforming, with an emphasis on transceiver algorithms for wireless communication systems and multi-functional MIMO. He has over a dozen publications and a patent.

Mon Feb 4th  2019 “The Origin of the First Supermassive Black Holes in the Universe” Dr Dan Whalen

Most massive galaxies in the universe today harbor supermassive black holes (SMBHs), with masses from a few million to tens of billions of solar masses.  But very bright quasars powered by billion solar mass BHs have now been discovered at redshift z ~ 7, or just 775 million years after the Big Bang.  They pose serious challenges to current theories of cosmological structure formation because it is not known how BHs this massive appeared by such early epochs.  I will discuss the possible origins of the first quasars and present new supercomputer simulations of how they could form in the first billion years of the universe.
