These are the pages dedicated to my scientific output. At the moment they include publications. In future I will add teaching material, software, datasets and additional (more or less) relevant miscellanea.
Optimal offspring size varies with maternal size and reproductive effort
An experiment in scientific publishing using web technologies
Forty years since Smith-Fretwell - an experiment with typesetting of scientific papers using web technologies. The scientific content is my own work on mathematical modeling of evolution of offspring size, in the context of an earlier work by Smith and Fretwell (1974).

patterns of solitary bees from capture-recapture

I combined theoretical models and results from
stochastic processes with dynamic optimization
techniques in order to study optimal life-history
strategies, such as optimal growth trajectories,
optimal size at maturity, and optimal offspring size.

I applied principal
component analysis and canonical discriminant
analysis to find the morphological traits that best
distinguish between the three developmental stages of
antlion larvae. Additionally, I applied regression
techniques to model larval growth, and Failure-Time
Analysis to estimate rates of mortality and
developmental transitions (such as molting, pupation
and emergence), and how such rates vary with larval stage,
body size, and population of origin.

I used data
on growth, development and survival of North American
grasshoppers, in order to find how individual
variation in such life-history traits affects overall population dynamics
and stability. I applied regression and Failure-time
analysis techniques in the statistical analysis.
Additionally, I applied models for stochastic
population dynamics in order to estimate effects on
