Franklin M. ("Lynn") Orr, Jr.
Keleen and Carlton Beal Professor in Petroleum Engineering, Emeritus
Current Research and Scholarly InterestsResearch
My students and I work to understand the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers.
Teaching
I teach a courses for graduate students on the mathematics of multiphase, multicomponent flow in porous media and on the thermodynamics of phase behavior. I also teach an undergraduate course on energy for freshmen.

Khalid Osman
Assistant Professor of Civil and Environmental Engineering and Center Fellow, by courtesy, at the Woods Institute for the Environment
BioKhalid Osman joined the department as an Assistant Professor of Civil and Environmental Engineering in autumn of 2022. His research spans the use of mixed quantitative-qualitative methods to assess public perceptions of water infrastructure, water conservation efforts, and the management of existing infrastructure systems to meet the needs of those being served by the systems. He currently is focused on the operationalization of equity in water sector infrastructure, conceptualizing equity in decentralized water and sanitation systems, water affordability, and stakeholder-community engagement in sustainable civil infrastructure systems for achieving environmental justice.
Khalid was the holder of a Bill and Melinda Gates Millennium Scholars Graduate Fellowship and also a Ford Foundation Predoctoral Fellowship. -
Stephen Palumbi
Jane and Marshall Steel Jr. Professor of Marine Sciences, Professor of Oceans and of Biology
Current Research and Scholarly InterestsWe're interested in ecological, evolutionary, and conservation questions related to marine (and sometimes terrestrial) organisms and ecosystems. We use evolutionary genetics and molecular ecology techniques, and our fieldwork takes us all around the world. Currently, we're studying coral diversity, the adaptive potential of corals in response to climate change, the movement of organisms between marine reserves, genetic changes in abalone in response to environmental.

Ayla Pamukcu
Assistant Professor of Earth and Planetary Sciences
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). -
Lamprini Papargyri
Postdoctoral Scholar, Earth System Science
BioLamprini Papargyri is a postdoctoral scholar at Stanford University co-advised by Professor Steve Davis and Dr. Ken Caldeira. She earned her PhD in Civil and Environmental Engineering from the University of Cyprus, where she worked under the guidance of Professor Panos Papanastasiou to optimize the durability of materials used in photovoltaic systems. Her doctoral research employed advanced computational modeling using 3D finite element methods and XFEM to simulate stress, cracking, and degradation mechanisms in photovoltaic materials.
At Stanford, Lamprini’s research lies at the intersection of climate policy, economics, and equity. Her current work explores how economies with income inequality can optimally allocate resources between income redistribution and emissions abatement. Beyond research, she has led and contributed to multi-million-euro research initiatives across Europe and remains deeply interested in the societal and ethical dimensions of emerging technologies. Broadly, she is interested in developing integrated models that inform equitable and sustainable pathways for climate mitigation and economic development.
