DESCRIPTION:The evaporation of a sessile droplet is a multifaceted problem
  of enduring scientific interest that is key to a wide range of everyday a
 nd industrial situations\, such as protein crystallography\, surface patte
 rning\, ink-jet printing\, and agrochemical spraying of plants. In this ta
 lk I shall review some of the recent developments in the study of evaporat
 ing droplets\, focusing on situations in which relatively simple mathemati
 cal models can give new insights into this fascinating multidisciplinary p
 roblem\, including the competitive evaporation of multiple droplets\, the 
 evaporation of a droplet on a non-planar substrate\, and the effect of the
  spatial distribution of the local evaporative flux on the deposit left on
  the substrate by a particle-laden droplet. The results presented in this 
 talk are the outcome of joint work with a large number of collaborators\, 
 including Drs Brian Duffy\, David Pritchard and Alexander Wray (University
  of Strathclyde)\, Professor Khellil Sefiane (University of Edinburgh) and
  Professor Colin Bain (University of Durham)\, and past and present resear
 ch students Gavin Dunn\, Jutta Stauber\, Feargus Schofield\, Hannah-May D
