Obtaining quantitative indicators to assess the impact of gender on health. Can be applied to other areas such as research or institutions, etc.
Designing of surveys and sampling designs.
Using different multivariate analysis techniques:
- Factor analysis to obtain indicators (scores) through extensive surveys rather than intensive surveys in order to improve the quality of information.
- Correspondence analysis to determine profiles or groups through quantitative information and categorical variables.
- Multivariate regression models (linear, logistic and Cox regression) to model the relationship between variables in different contexts (quantitative, categorical or time dependent).
Using different statistical software (mainly SPSS and SAS).

Areas of research

Mathematical models which explain the process of citation: Axioms / alternatives to the so-called “Matthew effect”.
Create a dynamic model of social networks that satisfactorily explain the distribution of citations.
To study citation speed in different areas.
To study the distribution of citations.
To design contrasts for such distributions, e.g., lognormal, exponential, etc.
To identify priority fields on science (cluster analysis of data).
Development of university rankings, in particular “Statistical methods for building Composite indicators” as a strategic tool for universities.
When and how mathematics, physics and / or economic theory enters into the applied area? A “survival” model designed to measure how long an article on theory takes to be cited by an academic article in the applied area. A comparative study of academic journals is proposed as well as an analysis of their progress over a given period of time.
Development of descriptive measures to compare the scientific production of different institutions.
