个人简介
I graduated as a B. Sc. in Marine Biology from Universidad de Concepcion, Chile. Right after graduating I entered a new post-graduate program by U. de Concepcion, the M. Sc. in Oceanography, for which I received a Deutscher Akademischer Austauschdienst scholarship.
My Master dissertation was about the food preference of a sea urchin species. I carried out experimental work and graduated from the Master's program in 1995. But as it turned out, I was a lousy experimental biologist. So my first paper, of which I am the single author, was about how to carry out the statistical analysis of food preference experiments, a statistical technicality that had ecologists scratching their heads at that time. Although this paper has been cited 201 times according to the Scopus database, it was rightly criticized and corrected by Bryan Manly, a leading statistician working in the biological sciences, then in the Dpt. of Mathematics and Statistics, University of Otago, New Zealand.
So obviously I went to New Zealand for doctoral studies in statistics with Bryan Manly as supervisor. For this I was blessed with an NZODA scholarship and the Universidad of Concepcion scholarship. As it turned out Bryan Manly was about to leave New Zealand. Six months after my arrival he left to continue his work in Wyoming. Richard Barker took me under his wing as my new supervisor.
Eventually during this time Richard became a Bayesian. I was not convinced but clearly something was not ok with frequentist inference (better called sampling distribution inference). I read a book by Richard Royall and another book by Anthony W. F. Edwards and then I was convinced. I became a likelihoodist, a would-be statistician content with examining the complete shape of likelihood functions and their approximations to make statistical inferences about what was going on in nature.
It took a long time to finish the doctoral dissertation. I had to escape to the Falkland Islands, taking a position there as stock assessment scientist, to finish the first draft while working for the Falklands government.
After graduating in 2009 I have been working mostly in the intersection between statistics, marine ecology and fisheries. I have also collaborated in several totally unrelated disciplines (finance, operations research, psycho-metrics, food chemistry) as a generalist statistical consultant.
I am now very much focused on fisheries and its strongly statistical branch, stock assessment. All my current work is in the assessment of stocks of small-scale, coastal fisheries, and other data-limited fisheries. It seems to me that apart from some technical issues, the assessment of large-scale, data rich fisheries is pretty much done, nothing much to discover or develop there.
Fisheries are the only large scale human industries producing food in a totally natural way, by hunting prey, prey whose population renewal is left to nature's own devices. Fisheries that are actively managed based on scientific knowledge of those processes of population renewal are in good condition or recovering, as shown by a leading expert in this field, University of Washington's biologist Ray Hilborn. Thus extending scientific methodologies of stock assessment that are working well for large scale data-rich fisheries, to the large majority of small-scale and other data-limited fisheries, seems a worthy pursuit.
