Intereses

Mi línea de investigación se centra en la determinación de los procesos evolutivos involucrados en la evolución del patrón corporal de los trilobites a lo largo del Paleozoico, mediante un enfoque multidisciplinar. Mi objetivo es desarrollar de un programa de investigación, pionero a nivel mundial, enfocado a la morfología funcional de los trilobites, que estudia tanto su biomecánica, como la biología del desarrollo de estos artrópodos extintos, así como su relación con los cambios ambientales durante el Paleozoico inferior. Un enfoque multidisciplinar, con la aplicación de nuevos métodos y tecnologías (modelado 3D, análisis cinemático, análisis de elementos finitos, simulaciones computacionales de dinámica de fluidos) y su combinación con métodos clásicos de geología y paleontología (bioestratigrafía, tafonomía, morfometría geométrica, cladística) revolucionará nuestra comprensión de la paleobiología de los trilobites, con implicaciones en la evolución temprana de los planes corporales en los artrópodos así como en sus relaciones filogenéticas. Los intereses específicos de investigación se centra en tres diferentes aspectos: 1) morfología funcional, 2) paleoecología y 3) biología del desarrollo. Además, de manera complementaria trabajo en otras líneas de investigación estrechamente relacionadas con las mencionadas. Dichas líneas se centrarán en la bioestratigrafía y la correlación del Cámbrico inferior y medio, bioestratigrafía del Ordovícico, y paleogeografía, tafonomía, sedimentología y estratigrafía del Paleozoico inferior.

Research interests

My research interest deals with the determination of the evolutionary processes involved in the evolution of the body pattern of the trilobites throughout the Paleozoic, by means of a multidisciplinary approach. My aim is to develop a world-leading research programme focused on trilobite functional morphology and biomechanics and its relationship with its developmental biology and ecology. I believe that the application of new methods and technologies (e.g. 3D modelling, finite element analysis) and its combination with classic methods (e.g. geometric morphometrics, cladistics) will revolutionize our understanding of trilobite palaeobiology, with implications for the early evolution of the arthropod bauplan as well as their phylogenetic relationships. A multidisciplinary approach, with the application of new methods and technologies (3D modeling, kinematic analysis, finite element analysis, computational simulations of fluid dynamics) and its combination with classical methods of geology and palaeontology (biostratigraphy, taphonomy, geometric morphometry, cladistics ) will revolutionize our understanding of the palaeobiology of trilobites, with implications for the early evolution of body plans in arthropods as well as their phylogenetic relationships.

My research interests lie at the intersection of three different subjects: 1) functional morphology, 2) palaeoecology and 3) morphological variation and developmental biology. In addition, I work on other lines of research closely related to those mentioned. These lines focus on the biostratigraphy and the correlation of the lower and middle Cambrian, biostratigraphy of the Ordovician, and paleogeography, taphonomy, sedimentology and stratigraphy of the Lower Paleozoic.
