    Assistant Professor of Earth and Planetary Sciences and, by courtesy, of Geophysics

    Current Research and Scholarly InterestsI have long been fascinated by magmas and volcanic eruptions, for reasons ranging from purely academic (trying to understand the magmatic construction of Earth’s crust) to purely practical (developing effective monitoring and mitigation strategies for volcanic eruptions). Consequently, my research revolves around understanding how, when, where, and why magmas are stored, evolve, and ultimately do (or do not!) erupt.

    Within this context, I focus on two main themes: (1) the temporal, chemical, and physical, evolution of magmas, and (2) the interplay between magma storage conditions in the crust and magmatic processes. I employ a multi-faceted approach to explore these topics, integrating data from multiple scales and perspectives; my studies capitalize on information contained in field relations, crystal and melt inclusion textures (sizes, shapes, positions), crystal and volcanic glass geochemistry, geochronology, phase-equilibria and numerical modeling, and experiments. As a function of this approach, I am also engaged in the development of novel methods to address petrologic problems in new, better, and more refined ways than is currently possible.

    A major focus of my research has been on supereruptions – gigantic explosive eruptions the likes of which we have never seen in recorded human history – but I am continually exploring other kinds of magmatic systems. I am currently particularly interested in the links (or lack thereof) between extrusive (i.e., erupted) and intrusive (i.e., unerupted) magmas, similarities/differences between large- and small-volume eruptions, and similarities/differences between magmas generated at different levels of the crust. I have also had a longstanding interest in the interactions and relationships between humans and their geologic surroundings (particularly volcanoes).

    BioPlants display enormous diversity of forms today that, have evolved over geological timescales after plants successfully colonized land. Currently, I am interested in learning more about evolutionary changes in plant structures including specialized reproductive organs of seed plants. I study plant fossil record from deep time and living plants with the aim to develop a better understanding of origins of plant reproductive structures and drivers of morphological evolution in plants. Previously, I have looked at spore-pollen record preserved in sedimentary rocks from Canada. These microscopic fossils and their distribution in space and time can help us elucidate the response of vegetation to past extinction events.

    Dorrell William Kirby Professor, Senior Associate Dean for Faculty Affairs, Senior Fellow at the Woods Institute for the Environment and Professor, by courtesy, of Biology,

    Current Research and Scholarly InterestsMy goal in research is to understand the interaction between environmental change and biological evolution using fossils and the sedimentary rock record. How does environmental change influence evolutionary and ecological processes? And conversely, how do evolutionary and ecological changes affect the physical environment? I work primarily on the marine fossil record over the past 550 million years.

  • Kenneth Peters

    Kenneth Peters

    Adjunct Professor, Earth & Planetary Sciences

    BioKen Peters retired as Geochemistry Advisor for Schlumberger in 2020 where he used geochemistry and numerical modeling to study petroleum systems. He has 42 years of experience with Chevron, Mobil, ExxonMobil, USGS, UC Berkeley, Stanford University, and Schlumberger and published >200 peer-reviewed geology, geochemistry, and basin modeling books and papers. He was Honorary Teaching Fellow at the University of Aberdeen in Scotland and Visiting Professor at Jacobs University in Germany. He is a Schlumberger NExT instructor, an EAGE Lecturer, Fellow in the Geochemical Society, AAPG Charles Taylor Fellow, and Adjunct Professor at Stanford University where he is a founding co-principal in the Basin Processes and Subsurface Modeling Industrial Affiliates Program [https://bpsm.stanford.edu/]. He was Chair of the 1998 Gordon Research Conference on Organic Geochemistry, Co-Convener of two AAPG Hedberg Research Conferences on Basin and Petroleum System Modeling (2009 and 2016), Chair of the AAPG Research Committee (2007-2010), and AAPG Distinguished Lecturer (2009 and 2010). He is principal author of The Biomarker Guide (1993, 2005), editor for the 2009 AAPG compact disk Getting Started in Basin and Petroleum System Modeling and principal editor of the 2012 AAPG Hedberg Series 4 volume on Basin Modeling: New Horizons in Research and Applications.

    Ph.D. Student in Geological Sciences, admitted Autumn 2022

    BioI grew up in Curitiba, a city in southern Brazil, and, moved to Rio de Janeiro to join the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) years ago.
    I have a strong grasp of the oil and gas industry, where I have been working for more than 15 years. I have a bachelor’s and master's degree in geology from the Federal University of Parana, Brazil and, I have become a public servant of the ANP, where I have held different technical and managerial positions. I spent these past 15 years working on the ANP’s large-scale strategic projects, conducting a geological evaluation for Brazil’s bidding rounds, and developing a multiyear geological and geophysical data acquisition plan for the Agency. I was also responsible for coordinating the first phase of the onerous assignment process, which authorized the Brazilian Government to onerously assign to NOC Petrobras up to 5 billion barrels of oil. I have also been directly involved in the location of two wells, which discovered two of the country's largest oil fields (Buzios and Mero fields). As a geologist researcher, my main objective aims at acquiring capabilities and developing the knowledge required to manage reservoirs to maximize oil recovery and extend the lifespan of oil fields as well as acquire a solid understanding of oil reservoir management to bring innovative knowledge to Brazil and help create guidelines to monitor oil field development and production in my country.
