Biography

Education: Carlos received his Bachelor of Science degree in Geology from the University of Puerto Rico-Mayaguez in 1993. He began his graduate studies in Geomorphology in the Department of Geology and Geophysics at the University of California-Berkeley (1993-95), and completed his Ph.D. from the Watershed Sciences program at Colorado State University (1998-2004). Since graduation Carlos has been Principal Investigator of several NOAA-funded projects in the Eastern Caribbean, while also working as an environmental consultant with the Island Resources Foundation. Carlos is also currently completing a post-doctoral appointment with the Department of Biology at the University of Puerto Rico-Río Piedras (2006-2008).

Research interests: Carlos’ major interests are in the field of Hydro-geomorphology, or the study of the interactions among landforms, land-shaping processes, and both surface and near-surface hydrologic processes. Even though skeptics still question the role of humans in affecting our planet’s climatic patterns, there is no doubt that humans are a dominant geomorphic agent and that our actions result in drastic changes to hydrologic and biogeochemical cycles. Most of Carlos’ work has had a strong environmental component by addressing the effects of anthropogenic alterations to the landscape on hydrologic and geomorphic processes, and their often detrimental effects on downstream aquatic habitats (e.g., salmon spawning gravels and coral reefs).

Carlos’ research interests also include understanding the linkages between geomorphic processes and biogeochemical cycles. He is currently working studying the role of mass wasting activity (i.e., landslides) in the carbon cycle of tropical montane environments. Little work has been done on this subject and his research tries to elucidate the basic question of whether landslide and associated debris flow activity accelerates the exportation of carbon from terrestrial systems or decelerates output rates by inducing net storage of carbon within depositional environments with residence times in the order of 1,000’s of years. The findings of this study could have important implications in the quantification and management of terrestrial carbon pools.

My study areas have included the humid forests of the Pacific Northwest coast of the U.S., and both dry and wet tropical forests of the Eastern Caribbean and Central America.

The physical landscape of Latin America and the Caribbean continues to be formed and reshaped by natural processes that have acted over geologic time scales. When these processes threaten life and property they are called natural hazards. Recent documented worldwide increases in the human and economic toll associated to natural disasters are presumably related to population growth, socioeconomic factors, and climate change. This course will cover some of the natural disasters that occur throughout Latin America and the Caribbean, one of the most natural hazard-prone areas on Earth. Through readings and in class discussions students will learn about the physical phenomena that incites natural hazards, while also emerging with a comprehensive view of the temporal and geographical distribution of hazards throughout the region. The course will present humans as susceptible to hazards but also as capable of affecting the incidence and degree of damage through direct intervention of the landscape and through deficient land use planning strategies, socioeconomic inequality, and climate change. Students will also gain a well-informed perspective on risk evaluation, short-term emergency response challenges, and hazard mitigation strategies employed throughout the region.
