Biostatistics

I am interested in applications of statistics and probability to biology, especially to marine ecology. I have developed methods for line transect surveys and CKMR (close-kin mark recapture) methods in particular. Key reference for CKMR:

Computational statistics

My opinion for a long time has been that Statisticians should have Automatic Differentiation (AD) in their toolbox. AD is the same type of technology as "back-propagation" used in Deep Learning. My conjecture has been that a combination of AD and the Laplace approximation is a powerful platform for fitting models with continuous latent variables. Software projects in which this idea is implemented are:

• TMB: https://github.com/kaskr/adcomp

• ADMB: http://admb-project.org/
