Meet the experts
Here at Ask A Biologist, we have some of the world's foremost experts in every field of biology. From palaeontology to neuroscience, from marine life to mammoths, they're all here. Meet the experts who answer the questions:
Professionally, I am a computer programmer; I work on dinosaurs in my spare time. I got my Ph.D from the University of Portsmouth in 2009, and am now an associate researcher at UCL. I work almost exclusively on the sauropods: the biggest, most beautiful and most exciting of all the dinosaurs. Being huge has its own problems, and they are fascinating ones (e.g. how can you carry all that weight, eat enough food to keep going, and deal with the metabolic demands?) Studying their fossils also has its problems: just getting huge bones on and off the shelves can be challenge enough, and very large animals tend to leave very incomplete remains -- in fact I and my colleague Darren Naish named the new sauropod Xenoposeidon in 2007 based on half of a single vertebra!
