The main interest of our group is the theoretical study of evolutionary systems of different kinds. We develop models inspired by the phenomenology observed in natural systems, chiefly molecular populations, viruses, and interacting agents at the cellular level and up.

The main interest of our group is the theoretical study of evolutionary systems of different kinds. We develop models inspired by the phenomenology observed in natural systems, chiefly molecular populations, viruses, and interacting agents at the cellular level and up. Our approach addresses the study of fundamental properties of adapting systems –with strong emphasis on their evolutionary origin— or, more specifically, tries to reproduce and eventually, to predict the response of such populations to endogenous and exogenous changes. In this context, we analyse the properties of the genotype-phenotype map through models such as the folded state of RNA sequences, focusing on the topological structure of neutral networks of genotypes and its relevance in adaptation and molecular innovation. Another main goal is to understand the survival strategies of viruses, including the relevance of multipartite genomes or the ecological effect of viral satellites. At a higher organizational level, we are also interested in modelization of the interaction between agents organized in networks that vie for resources, food, or mates, as competitive interactions represent one of the driving forces behind evolution and natural selection in biological systems. Finally, we explore the application of complex systems to biotechnology through the development of analysis techniques with environmental and health purposes. We have applied graph theory to antibody microarrays to improve the characterization of experimental samples, with direct application to allergy control, toxin detection in fresh water ecosystems, and identification of potential biomarkers in space missions. Our studies of viral response to antiviral treatments have determined optimal modes of drug administration to minimize viral load and mutant escape.

1. Types of cookies as the entity that manages:

Depending on who the entity operating the computer or domain where cookies are sent and treat the data obtained, we can distinguish:

- Own cookies: are those that are sent to the user's terminal equipment from a computer or domain managed by the editor itself and from which provides the service requested by the user.

In the event that the cookies are installed from a computer or domain managed by the editor itself but the information collected by these is managed by a third party can not be considered as party cookies.

2. Types of cookies as the length of time that remain active:

Depending on the length of time that remain active in the terminal equipment can be distinguished:

- Session cookies: cookies are a type designed to collect and store data while the user accesses a web page. Are usually used to store information that only worth preserving for the service requested by the user at any one time (eg a list of products purchased).

- Persistent cookies: cookies are a type of data which are stored in the terminal and can be accessed and treated for a period defined by the head of the cookie, and can range from a few minutes to several years.

3. Cookies types according to their purpose:

Depending on the purpose for which the data are processed through cookies, we can distinguish between:

- Technical cookies: these are those that allow the user to navigate through a web page or application platform and the use of different options or services it exist as, for example, control traffic and data communication, identify the session, access to restricted access parts, remember the elements of an order, make the buying process an order, make an application for registration or participation in an event, use security features while browsing store content for dissemination videos or sound or share content via social networks.

- Customization cookies: these are those that allow the user to access the service with some general characteristics based on a predefined set of criteria in the user terminal would eg language, the type of browser through which you access the service, the locale from which you access the service, etc.
