Research Areas
Research Interests
In 1997, I began to lecture at UTD teaching The Oceans, a self-paced interdisciplinary science course. Over the last several years I have been teaching a number of lower- and upper-level undergraduate courses, first as a Teaching Assistant, and then as a Lecturer fully responsible for lectures and labs. Currently, I am involved in the following courses: Oceanography, Paleontology, Earthquakes and Volcanoes, GRELA and Physical and Historical Geology. Online course development, Implementation and teaching. Increasing student enrolment from 173 to 520 students in one year, It involved three courses up to Fall 2010: The Oceans , Earthquakes and Volcanoes and Physical Geology.
Main interest: Stratigraphy, biostratigraphy, and micropaleontology as working tool. Presently I’m working in Mesozoic microfossils, particularly Radiolaria. This group of microfossils intensively studied only in the past thirty years; need to be calibrated to the classic ammonite zones defining the Jurassic- Cretaceous stratigraphy.
The research has been extended to the subsurface of the North GOM (Louisiana) where a well preserved fauna of Radiolaria from the deepest part of the Basin shows good potential as a subsurface tool. I am extending the research to other related Mesozoic basins, including the whole Gulf of Mexico in the border with Texas and south Central area. Industry interest on the research is high.
I’m also working on active research on the Mariana Forearc system sampling with submersible and mapping, on areas currently poorly known. As always I involve undergraduate students in the process of research. Participating on the Yokosuka” Voyage No. YK 10 - 12 September – October 2010: Participant in Shinkai 6500 diving in the Mariana forearc. Dive #1232, 6,332 meters. October 2010. Currently analyzing sediment and biostratigraphic samples.
