7. Prof. Robert Smith?

Robert Smith? (actually Robert Joseph Smith, born October 28, 1972 in Australia) is an Australian – Canadian mathematician who became internationally known for his scientific work on zombies . He also published several books on the television series Doctor Who and a textbook on the use of mathematical models for the study of infectious diseases. The question mark looks at Smith? as part of his name. Also, in his publications, he gives the name Smith? on. Officially, his name is Smith. [4]

Smith? studied mathematics at Macquarie University in Sydney and received his Bachelor’s degree in 1994. He then moved to the Canadian McMaster University, where he received the master’s degree in 1996 and earned his doctorate in 2001. In his doctoral thesis, he studied the technique of self-cycling fermentation, which can be applied in wastewater treatment and the disposal of toxic waste.

After earning his doctorate, he worked at the University of Western Ontario, where he first dealt with the mathematical study of disease, at the University of California, Los Angeles and at the University of Illinois at Urbana-Champaign. While living in the United States, Smith took? in addition to the Australian’s Canadian citizenship.

Today he is Associate Professor at the University of Ottawa. Smith published in 2008? the textbook Modeling Disease Ecology with Mathematics. In 2009 he was involved in the creation of a paper in which the outbreak of a zombie epidemic was mathematically modeled. [6] This work has also been reported in international media. Smith? published in the following years more articles as well as a book about zombies.

Further media attention was given to Smith? through a publication with his student [7] Valerie Tweedle from the year 2012. In it the hype around the pop singer Justin Bieber is examined.

8. Prof. Jane Hutton

Professor Jane Hutton works in medical statistics, with special interests in survival analysis, meta-analysis and non-random data. Her methodological research largely focuses on developing models to answer questions raised by health care colleagues, and patients. For example, collaborations with epilepsy specialists in meta-analyses led to papers on biases due to within study selection of outcomes and sub-groups, and to joint models for pre-randomisation seizure counts and post-randomised trials. Collaboration on a trial of ankle sprains has led to models for recovery rates with skew, bounded scores, with missing data.

Professor Hutton has major collaborations in cerebral palsy and epilepsy. Her work with Professor Peter Pharoahand Dr Allan Colver, on life expectancy in cerebral palsy, has had a substantial effect on the size of awards in medico-legal cases. This work is widely cited nationally and internationally. In epilepsy, she has contributed to many Cochrane reviews of anti-epileptic drugs. She has worked with Professor Tony Marson, of Liverpool University Neurosciences Department, on various projects. Recently, Professor Marson and Hutton collaborated with Professor Jim Smith to explore the role of Chain Event Graphs in modeling and managing chronic diseases.

Professor Hutton’s research has had impact through clinical guidelines and in legal cases. Work in epilepsy is cited in National Institute for Clinical Excellence (NICE), SIGN and WHO guidance. Medico-legal cases have addressed life expectancy of people with cerebral palsy, spinal cord injury and traumatic brain injury, and adverse effects of drugs. Expert witness reports have been provided for cases in Australia, Canada, Eire, Hong Kong, South Africa and the four countries of the United Kingdom. The total impact is at least £100 million.

Professor Hutton has written extensively on ethics and philosophy of statistics, in response to challenges arising from medical research and discussions with international statistical colleagues and philosophers. She has contributed to Research Council ethics guidelines.

External Roles:
Professor Hutton is a non-executive director and trustee of USS, from 1 November 2015. She is the Royal Statistical Society co-ordinator for a partnership between AIMS and RSS.
Professor Hutton was a member of the Core Methodology Panel, National Institute for Health Research (NIHR), 2011-2015, and the Education Committee of the International Biometric Society, 2013-2014. She was a member of the NIHR TCC Fellowship Panel, 2011-2013; the selection committee for the Health Research Board in Ireland, 2012. She has taught at AIMS South AfricaAIMS Ghana and AIMS Tanzania. Reflections on her experiences and the opportunists are here.

9. Dr. Bubacar Bah

Dr Bubacar Bah is the German Research Chair of Mathematics with specialization in Data Science at AIMS South Africa. He received a BSc degree (with sum cum laude) in mathematics and physics from the University of The Gambia, where he worked as a Graduate Assistant; the MSc degree in mathematical modeling and scientific computing from the University of Oxford, Wolfson College; and the PhD in applied and computational mathematics at the University of Edinburgh, Scotland, under the supervision of Professor Jared Tanner. His PhD research was on compressed sensing, in particular on random matrix theory questions arising from compressed sensing and signal processing in general. For some of his PhD work he has received the 2010 SIAM Best Student Paper Prize for his paper Improved bounds on restricted isometry constants for Gaussian matrices published in the SIAM Journal of Matrix Analysis.

His first post-doc was at the Laboratory for Information and Inference Systems (LIONS) in Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland, working on sampling strategies and designing algorithms for compressed sensing and sparse approximation. He also worked on machine learning, in particular learning linear embedding of high-dimensional data. His second post-doc was at the Department of Mathematics and the Institute of Computational and Engineering Sciences (ICES) at the University of Texas at Austin. While here, Dr Bah’s research continued in the areas of signal processing, machine learning and randomized numerical linear algebra. He was at the same time a lecturer at the Department of Mathematics teaching undergraduate Differential Equations and Applied Linear Algebra courses.

More precisely, Bubacarr is an applied and computational mathematician and his research interest is at the intersection of Applied Mathematics and Computer Science. He worked in the general area of signal and data processing and machine learning. In particular, his work was on the design and analysis of sampling strategies and algorithms for compressed sensing and learning linear embeddings of high-dimensional data sets. Some of his works relates to random matrix theory and numerical linear algebra; while some relates to scientific computing and the use of high-performance computing (HPC) resources.

His research will now focus on data science, as the new German Research Chair of Mathematics with specialization in Data Science. He plans to develop a vibrant research group on data science: conducting research in foundational mathematical and computational methods and techniques (modeling, sampling, algorithms, etc) for data science problems from biomedical sciences, engineering, social sciences, etc. In particular, there would be a significant emphasis on associated the scientific computing issues, which would include the utilization of HPC resources to address scalability challenges arising from the Big Data nature of these problems. His Chair on data science cannot come at a better time for Africa. There are a wide range of data science problems in Africa from finance, biomedical sciences, manufacturing, power systems, transportation, and so on, that are in need of data science research and technologies. A lot of developed economies like the USA and Germany has integrated data science research and technologies in almost every sector of their industries to improve efficiency and effectiveness of systems like engineering, business, education, government services, etc. The research output from this Chair is hope to have a significant impact in industries in South Africa, and Africa in general and Germany via the collaboration with German researchers, which is a key component of this Chair. Furthermore, the Chair gives Bubcarr the opportunity to engage in other academic activities that will contribute to the development of mathematics research and education in Africa.
