I've been lucky enough to do a fair bit of traveling through my studies as a biologist; I visited Honduras to research my undergraduate dissertation, I went to South Africa for a field course during my masters degree, and as a PhD student I undertook two solo field seasons in Brazil.
Here are the details of some of my previous trips:
Asia / Australasia 2013 / 2014
Argentina / Brazil 2011
Brazil 2010
South Africa 2009
Honduras 2007
