Investigación

Mi investigación básica documenta la formación geológica de arrecifes modernos y fósiles e intenta identificar procesos ecológicos y geológicos que controlan el inicio, desarrollo y muerte de sistemas arrecifales. Actualmente tengo varios proyectos enfocados a esta área:

  • Desarrollo de sistemas arrecifales modernos a lo largo de la costa Caribe de México y el Banco de Campeche.
  • Arrecifes Vestigiales del Holoceno

Usando información proveniente de estos registros arrecifales, mi investigación se enfoca a identificar la interacción entre el clima, la dinámica de la capa de hielo y el cambio en el nivel del mar durante ciclos glacial-interglaciar. Un aspecto importante es determinar si el calentamiento global podría desestabilizar las capas de hielo que quedan en la tierra y causar una rápida elevación del nivel del mar en escala de metros. Para responder a esta preocupación, intento usar sucesiones arrecifales para restringir y cuantificar la interacción entre las capas de hielo y el nivel del mar durante interglaciares cálidos del Pleistoceno. Actualmente tengo varios proyectos relacionados con este problema:

  • Significado climático de Sistemas Arrecifales del Pleistoceno en la Península de Yucatán (Fundado: DGAPA, Proyecto # IN218799).
  • Significado climático de Sistemas Arrecifales del Pleistoceno en islas elevadas de la Provincia Arrecifal Caribe-Atlántico.

 

gray dot Docencia

Además de la investigación, otro compromiso es enseñar y entrenar estudiantes a ser científicos y pensadores críticos. Esta tarea es muy importante pues la sociedad moderna esta basada en ser capaz de discernir críticamente entre la verdad y lo falso, ya sea en áreas judiciales, políticas o económicas. Entrenar estudiantes para pensar críticamente es por lo tanto de importancia nacional.

Tengo 3 proyectos disponibles para estudiantes:

1. Sedimentary development of the reef lagoon in Puerto Morelos (Maestría o Doctorado).
2. Relic sediments of the fore-reef shelf off Puerto Morelos (Maestría o Doctorado).
3. Relic reef deposits on the fore-reef shelf off Puerto Morelos (Maestría o Doctorado).

Tengo experiencia enseñando los siguientes cursos:

1. Biología Marina (UNAM).
2. Métodos Oceanográficos (UNAM).
3. Presentaciones Orales y Escritas de Trabajos Científicos (UNAM).
4. Earth, Our Habitable Planet, (Indiana Univ.).

Research Summary

My basic research documents the geological formation of modern and fossil coral-reef systems and attempts to identify the ecological and geological processes that control their initiation, development and demise. At present, I have several research projects focussed on this basic research:

  • Development of modern reef systems along the Caribbean coast of Mexico and the Campeche Bank.
  • Relict Holocene reef systems

Using insights gained from these reef records, my applied research focuses on identifying the interaction between climate, ice-sheet dynamics and sea-level change that have taken place during glacial-interglacial cycles. A particularly important aspect of this effort is assessing if global warming could destabilize the Earth’s remaining ice sheets and cause a rapid meter-scale sea-level rise. To address this concern, I am attempting to use fossil reef successions to constrain and quantify the interaction between ice-sheets and sea-level during warm Pleistocene interglacials. At present I have several research projects related to this problem:

  • Climatic significance of Pleistocene Reef Systems of the Yucatan Peninsula (Funded: DGAPA Project number IN218799).
  • Climatic significance of Pleistocene Reef Systems on uplifted islands in the Caribbean-Atlantic Reef Province.

 

gray dot Teaching & Training

In addition to research, my other major commitment is to teach and train students to become scientists and critical thinkers. This task is particularly important because the basis of any modern society is being able to critically discern truth from falsehood, whether this be in judicial, political or economic arenas. Training students to think critically is therefore of national importance.

Presently, I have 3 student projects available:

1. Sedimentary development of the reef lagoon in Puerto Morelos (M.Sc. or Ph.D).
2. Relic sediments of the fore-reef shelf off Puerto Morelos (M.Sc. or Ph.D).
3. Relic reef deposits on the fore-reef shelf off Puerto Morelos (M.Sc. or Ph.D).

In terms of teaching, I have been involved in disseminating the following courses:

1. Marine Biology (UNAM).
2. Oceanographic Methods (UNAM).
3. Oral and written presentations in Science (UNAM).
4. Earth, Our Habitable Planet, (Indiana University).
