RESEARCH AND TEACHING STATEMENT

JUAN CARLOS SILVA-TAMAYO, PhD Assistant Professor, University of Houston

SCIENTIFIC RESEARCH My primary scientific and educational goals are summarized by the following five questions: 1) How do changes in environmental conditions (i.e. global warming, ocean deoxygenation; and ocean acidification) affect the global biogeochemical cycles at both geologic and human time scales? 2) How does environmental change relate to major evolutionary crises and animal diversifications? 3) Which innovative proxies/approaches can we develop to quantify such effects and relationships? 4) Which training activities, both theoretical and practical, can we design to effectively prepare the next generation of geoscientists and STEM workforce to provide quantitative answers to the effects of the environmental changes associated to the ongoing anthropogenic activities? 5) How can we make the general public and the decision-making agencies aware about the future environmental issues affecting the global population? The above questions are especially relevant today as the anthropogenic activities are altering the global environmental system at alarming rates, and quantification of their effects on the global environment requires the application of cutting edge analytical techniques and comprehensive outreach activities. The above question are also important as we look back into the Earth’s past to investigate ancient biologic crises closely linked to major environmental perturbations. The complexity of the processes associated to periods of environmental/biologic upheavals requires field- and laboratory-based research on individual and globally distributed stratigraphic sections and basins, as well as the integration of stratigraphic information with geochemical (elemental and isotopic) data and paleobiologic patterns that require different approaches and interpretations based on relevant mathematical modeling studies. The integration of the so many different approaches and types of information is a challenging and exciting work towards which I am putting an important part of my efforts as an Assistant Professor of the EAS-UH. The integration of stratigraphic, geochemical and paleobiologic information has allowed me to continue giving answers to some of the fundamental questions I want to address with my research activity. My research activity as an Assistant Professor at the EAS-UH has included starting several multinational and multidisciplinary scientific collaborations, mentoring several undergraduate and graduate research projects, and starting collaborations and joint research activities with the oil and gas industry. My activities have required introducing new cutting edge analytical techniques to the EAS-UH. These new analytical techniques have positively impacted the EAS main research activities as they being used by EAS students and professors. These techniques have also been used by researchers from other departments within the UH system (i.e. Anthropology). Several of the cutting edge scientific and teaching activities I have performed as an Assistant Professor are summarized in Items 1-4. Items 5-6 are areas of interest that I am developing in order to add breadth to my research program at UH. 1. Use of multi isotope proxies in paleoceanographic and paleobiological research. This research combines carbonate sedimentology, petrography, stratigraphy, and traditional and non-traditional stable isotope geochemistry and elemental geochemistry to investigate and quantify the effects of environmental change on global biogeochemical cycles. Specifically, this research aims to quantify the extent of ocean oxygenation and acidification during different intervals of the Earth history experiencing major biological crises and diversifications (e.g., the Neoproterozoic Snowballs, the Permian-Triassic transition and the Cretaceous Weissert, OAEI and OAEII Oceanic Anoxic Events). To date two PhD student (Manuel Paez, Carlos Andrade) and five undergraduate students (Ashley Gerrediaga, Rebecca Rea, Maria Alejandra Pinzon, Carlos Villacres and Yang Yun) are actively working in this research under my advice. This research has required the development of new analytical techniques that have enhanced the analytical capabilities of the EAS. Some of these activities are:

a. Acquisition, installation and development of clean laboratory facilities for determination of stable Mo, U, and Sr isotopes in different matrices.

b. Acquisition, installation and development a laboratory facility for extraction and determination of sulfur S and C stable isotopes in different matrices.

c. Acquisition, installation and development of clean lab facilities for determination of iron species (Fe speciation) and major and minor elements in fine grained sedimentary rocks and carbonates.

d. Acquisition and installation of a XRF core scanner for non-destructive determination of major and minor elements in geologic and archeological materials

e. Acquisition and installation of a Microscopy/Palinology/Vitrinite Reflectance facility for study of black shales and modern sediments.

Results from the Permian-Triassic research have been published in the Proceeding of the Natural Academy of Sciences (see CV for details). Results from the Weissert Event have been published in the Brazilian Journal of Geology. This work had count with the participation of two visiting scholars from Colombia and two female Predocs from Germany and China. Other two manuscripts on the Permian-Triassic transition have been also submitted to the PNAS and GSA Bulletin. Results OAEI and II have been presented as invited talks in several international conferences. Three manuscripts focusing in the OAEI and OAEII events are in preparation and include the author and co-authorship of EAS/UH students. One PhD student (Lucien Nana Yobo) is currently involved in the use multi-proxy stable isotope approach involving δ44/40Ca, δ18O, δ88/86Sr, 87Sr/86Sr to investigate the relationship between major extinction events and the effects of rapid changes in atmospheric pCO2, global warming and ocean acidification on the marine carbonate budgets (e.g., Permian-Triassic, Cretaceous Oceanic Anoxic Events- OAEs). Three additional students (Trey Lobprise, Diana Krupnic and Meri Mcculley. The Swiss National Science Foundation and the European Union throughout the Marie Curie FP7 Actions program have funded these research projects. Additional funding has been secured trough the Colombian National Science Foundation (US$ 100,000) to expand this research to the Jurassic OAEs. Funding will be used to support one additional PhD student (Giovanni Nova) for two years starting in Spring 2017. One research proposal was submitted in Fall 2015 to the PRF of the American Chemical Society. One research proposal has been submitted in Summer 2016 to the NSF (Carrer Proposal). These research projects are providing important information to forecast the effects of three major environmental concerns of the global societies i.e., global warming, ocean acidification and expansion of the oxygen minimum zones in the global oceans (Silva et al., 2010a,b, Silva et al. submitted, see CV). These projects are being conducted in collaboration with globally recognized scientists from different universities, including Stanford University (USA), Kiel University-Geomar Institute (Germany), University of California Santa Cruz (USA), Leeds University (U.K.), Hannover University (Germany), Munster University (Germany), Curtin Technologic University (Australia), Universidade Federal de Pernambuco (Brazil), Universidade de Sao Paulo (Brazil), Graz University (Austria), Universidad de Caldas (Colombia), Universidad Nacional de Colombia. This research area has been the base of new courses taught at graduate level (chemostratigraphy). 2. Evolution of the Meso-Cenozoic Pan-Tropical Carbonate Factory. During the last five years my research has also focused on timing changes in the Cenozoic/Mesozoic marine carbonate factories along the tropical Circum-Caribbean. This research combines precise carbonate U-Pb geochronology and stable (δ13C, δ18O) and radiogenic (87Sr/86Sr) isotope stratigraphy to investigate the relationship between major changes in the Meso-Cenozoic carbonate factories and global climatic events i.e., the onset and expansion of the Antartic ice sheets (Silva et al. 2014, submitted). It also focuses on how changes in the occurrence of coral reefs along the Circum-Caribbean relate to major tectonic events in this region (i.e., exhumation of the Andes and the closure of the Panama seaway). This research has also allowed precisely dating the opening and evolution of several sedimentary basins along convergent margins such as the SE Circum-Caribbean (Colombia, Venezuela, Panama). As the opening of several of these sedimentary basins is closely related to the interaction between the Caribbean and South American plates, this research has also contributed to the Cenozoic paleogeographic reconstruction of northern South America and the Caribbean. The combination carbonate of U-Pb dating, chemostratigraphy and carbonate sequence stratigraphy have been final successfully used to date and regionally correlate Cenozoic carbonate oil and gas reservoirs (Silva et al., submitted). This research required the development of the Sr-isotope analytical technique using TIMS. This investigation counted with the participation of three PhD students and one MSc student from the EAS-UH. This research is being conducted in collaboration with internationally recognized scientists from University of Miami (USA), Kiel-Geomar (Germany), Smithsonian Tropical Research Institute (Panama), Universidade Federal de Pernambuco (Brazil), National University of Colombia (Medellin, Colombia), Universidad de Caldas (Colombia). One proposal to support this investigation was submitted in Spring 2015 to the NSF and two additional ones will be submitted in Fall 2016. The material from this research was used in one graduate level course (chemostratigraphy) and two undergraduate level courses (introduction to depositional environments; stratigraphy). 3. Use of sequence stratigraphy and multiproxy provenance analysis in Cenozoic continental basins to reconstruct climate and the paleogeogaphy of convergent areas; the case of northern South America. This research aims on investigating how the continental sedimentary records express changes in the Cenozoic climate along the Neotropics. This research applies a multi-proxy approach comprising sequence stratigraphy, U-Pb dating, heavy mineral characterization, sandstone petrography and siltstone geochemistry in several sedimentary successions along northern South America. This information has been used to date the interaction between Central America and South America, thus contributing to the objectives of Item 2. This research has also allowed investigating the occurrence of important unconventional resources, such as coal associate gas (coal gas methane), along several continental Cenozoic basins in northern Colombia. Results from this research have been published in Science Magazine in 2015. One more manuscript has been submitted to Sedimentary Geology in 2016. This research counted with the participation of two visiting scholars at UH. This research favored from the development of the XRF core scanner and clean lab analytical techniques. This research is being conducted in collaboration with scientists from Washington State University (USA), National University of Colombia (Medellin, Colombia), Universidad de Caldas (Colombia), Andes University (Colombia) and the Smithsonian Tropical Research Institute (Panama).

One proposal to support this research is being written and will be submitted in Fall 2016. The material from this research was used as didactic material in two undergraduate classes (introduction to depositional models; stratigraphy) 4. Holocene Paleoclimatic reconstruction along NW South America: A multi-proxy approach from stalagmite records. The 20th century has witnessed an exponential increase in anthropogenic CO2 emissions to the atmosphere. Investigating the consequences of anthropogenic (industrial) CO2 emissions on global climate is a key research priority for the international community. In recent years, particular attention has been given to the possible future effects of increased anthropogenic CO2 emissions on the marine and continental ecosystems, as well as on the global water resources as their impairment may put at risk the global population. In 2012, I started investigating the Holocene climate variability along the tropical northern South America. This research will complement my research on long-term consequences of environmental change (Item 1) as it focuses in short-term scales comparable to that of the Anthropocene. In association with Professor Francisco Cruz (University of Sao Paulo, Brazil) I am using U-series dating and stable O and C isotope time series in speleothems (i.e., stalagmites) to investigate climate variability as well as changes in atmospheric pCO2 and rain regimes in the Neotropics. This research has been conducted with the financial support of the UNESCO (Man and Biosphere Program). Our group has also received financial support from the Brazilian Research Council. Results from this research are being used to write one manuscript. 5. Refining the cycling of major metal isotope cycles in the critical zone. Over the last five years, I have applied Mo, U, Ca, Mg isotopes in different fields of geosciences including paleoceanography, paleoclimatology and paleobiology. One of the main scopes of my research is to use multi-isotope geochemistry to link changes in the global biogeochemical cycles to environmental change (Item 1). Despite the potential information that non-traditional stable isotopes can provide regarding past environmental changes and biogeochemical cycles, modeling realistic scenarios of the effects of past environmental changes on the global biogeochemical cycles has remained challenging due to the limited understanding of the modern processes governing the fractionation and cycling of such isotopes across a range of conditions, i.e. along the “critical zone”. For example, there is a lack of information on the cycling and fractionation of non-traditional stable isotopes along the critical zone under conditions of varying temperatures (e.g., temperate vs. tropical climates), varying vegetation coverage, varying tectonic regime (tectonically active vs. tectonically stable areas), varying isotope reservoirs (source areas displaying significant lithological contrast vs. areas of homogeneous lithology) among others. This has limited our ability to establish the underlying causes driving changes in the fluxes of stable isotopes during periods of varying climate, varying terrestrial vegetation and varying tectonic activity. Improving our understanding of fractionation and fluxes of non-traditional stable isotopes under very contrasting conditions is vital to improve the quantification (based on non-traditional stable isotope multi-proxies) of the effects of past environmental changes on global biologeochemical cycles. This is especially true when modeling and quantifying those effects during periods of contrasting global climates and tectonic regimes in the geologic past. I am currently put special effort to develop a research program aiming at quantifying the cycling and fractionation of non-traditional stable isotopes in the critical zone along areas displaying contrasting climatic conditions, tectonic regimes, vegetation coverage and lithology. This research, which will involve extensive field work, isotope and elemental geochemistry, computational and quantitative models, etc, will complement my current research (Item 1) and will provide further opportunities for postdocs, predocs and graduate students to develop multi-proxy research projects. This Item is the base of my Career Proposal submitted in Summer 2016 to the NSF. One additional proposal has been submitted in summer 2016 to the NSF (P.I. Allan Brandon). This research has favored from the new analytical techniques (Mo, U, Ca, Sr, Ba) developed in the existing geochemistry facilities in the EAS-UH. 6. Environment evolution, human health and the Anthropocene. Scientific research focused on the applications of non-traditional stable isotopes on environmental assessment/remediation and on human evolution and health is still in dippers at the UH and in general in the US. I am currently putting efforts to develop new analytical techniques that allow determination and quantification of the fate of several hazardous transition metals (i.e. Cr, As, Cd, Hg) in the critical zone and its consequences in human evolution and health. Because anthropogenic activities directly impact the environment, I am integrating Item 5 with anthropologic and biomedical research. Specifically, I am pursuing investigations in the medical field aiming to assess the relationship between anthropogenic contamination and human health using stable isotopes. With the increase of life expectation of humans, I expect to succeed on acquiring funding to perform biogeomedical research in severe US illnesses such as cancer, osteoporosis, Alzheimer and Parkinson. These investigations will be complemented with geoanthropologic research, a field that will complement my ongoing research in Item 4. The anthropologic research is being currently developed with the collaboration of Professor Alex Bentley, Chair of the Anthropology Department/ UH. One proposal is being written and will be submitted in Fall 2016.
