The next meeting of the Mathematical Biology Discussion Group will be held on Tuesday the 28th of August at 2pm in Carslaw room 707A. Our guest speaker for the meeting will be Professor Ralph Nanan, Head of the Nepean Paediatric Immunology Unit of the Sydney Medical School Nepean (University of Sydney). Professor Nanan will discuss the potential adaptive value of pre-eclampsia in human lifehistory; he is seeking collaborators to help him further explore his ideas with the help of models. The talk will be fascinating and could lead to future collaboration on a project of great potential for anyone who is interested.
