Postdoctoral Opportunity: Climate consequences of regional climate forcing

Department: DGE – Global Ecology

Salary: TBD Competitive Salary

Location: Stanford, CA

We seek to help develop a more general understanding of climate consequences of regional changes in climate forcing, both to contribute to fundamental climate science and to better inform decision making. We have done several studies showing that the same changes made in different places can have substantially different climate effects. For example, deforestation effects differ with latitude (Bala et al., PNAS, 2007), ocean heat flux effects vary with ocean basin (Praetorius et al., Nature Comm., 2018), and aerosol effects vary (by up to an order of magnitude!) with country of emission (Persad et al., Nature Comm., 2018). It is likely that attempts at regional-scale geoengineering would have global scale effects that would differ based on where and how that geoengineering occurred. Further, the spatial and temporal pattern of increased precipitation would vary with the location and timing of increased evaporation – as would the balance of lapse-rate vs cloud vs greenhouse-gas aspects.  Are there general theories that would allow the basic response of the climate system to different regional forcings to be predicted without running a climate model?

We are looking to hire one (or possibly two) postdoctoral research scientists who would undertake geophysical modeling to investigate issues raised by the comments above. The model used could be anything from a high-resolution local model to a coarse-resolution global model, depending on the problem being addressed, although we have been using primarily NCAR’s CESM for this sort of investigation.

This position will involve working with Ken Caldeira at the Carnegie Institution for Science Department of Global Ecology on the Stanford University campus, and other collaborators. In our group, we maintain an exciting collegial atmosphere, working in a diverse collection of people that includes climate modelers, energy-system analysts, assessment experts, and field researchers. It is assumed that the successful candidate will drive work in this broad area as their main research project, but will both rely on and contribute to collaborative relationships with other postdocs in our group, as well as external collaborators. We prefer candidates who will enrich the intellectual diversity of the research group and are actively interested in strengthening interdisciplinary connections within the focal areas of the research group.

Carnegie Institution post-docs have access to most Stanford facilities. The initial term will be for one year with the potential for renewal for a second year up to a maximum of four years. Positions are available now and we are flexible regarding start date.  In there is a particularly strong candidate pool, more than one position could be offered under this posting.

Candidates with a PhD and a track record of success are encouraged to apply. General skills and ability, and interest in understanding the feasibility and consequences of various ocean engineering proposals, are more important than specific domain knowledge. Achievement in scientific publication, or comparable evidence of being able to complete high quality work in a timely manner, is a primary filter determining which applications receive greater consideration. Compensation for this position includes a competitive salary and comprehensive benefits.

Informal inquiries about these positions can be made by emailing Ken Caldeira at kcaldeira@carnegiescience.edu  however formal applications for employment must be submitted by clicking on the blue bar below.

Postdoctoral Opportunity: Geophysical modeling of ocean engineering proposals

Department: DGE – Global Ecology

Salary: TBD Competitive Salary

Location: Stanford, CA

There have been various proposals to generate electricity by exploiting the temperature difference between the ocean thermocline and the ocean surface (e.g., Ocean Thermal Energy Conversion, or OTEC). Further, there have been suggestions that global warming could be slowed by pumping heat from the surface ocean to the deeper ocean, or that thermal and/or chemical conditions suitable for coral reefs could be maintained through some ocean engineering efforts. It has also been suggested that ocean dead zones could be addressed by pumping oxygen-rich surface waters to anoxic regions at depth.

We are looking to hire a postdoctoral research scientist who would undertake geophysical modeling to address some of the issues raised by these proposals. We have done some initial highly-idealized modeling at unrealistic scale (e.g., Kwiatkowski, Ricke and Caldeira, 2015), and would like to understand whether those results apply to deployments at more plausible scale.  The model used could be anything from a high-resolution local model to a coarse-resolution global model, depending on the problem being addressed.

This position will involve working with Ken Caldeira at the Carnegie Institution for Science Department of Global Ecology on the Stanford University campus, and other collaborators. In our group, we maintain an exciting collegial atmosphere, working in a diverse collection of people that includes climate modelers, energy-system analysts, assessment experts, and field researchers. It is assumed that the successful candidate will drive this effort as their main research project but will collaborate with other postdocs both on this work and on their work. We prefer candidates who will enrich the intellectual diversity of the research group and are actively interested in strengthening interdisciplinary connections within the focal areas of the research group.

Postdoctoral Research Associate: Quantifying climate impacts on inland and coastal eutrophication

Department: DGE – Global Ecology

Salary: TBD Competitive

Location: Stanford, CA

The Department of Global Ecology at the Carnegie Institution for Science (CIS) is seeking Postdoctoral Research Associates to contribute to research that aims to quantify climate change impacts on freshwater and coastal water quality via influences on nutrient delivery to, and on conditions within, water bodies. Our approach is highly data-driven, with a common methodological thread being the development and application of statistical approaches for optimizing the use of limited in situ and remote sensing environmental data.

There will be considerable flexibility regarding specific scientific questions to be examined, but potential areas of focus include:

  • Attribution of historical water-quality trends and extreme events to climate change and variability;
  • Assessment of historical and future nutrient loading, phytoplankton blooms, and hypoxia in data-poor regions;
  • Development of approaches for using modern satellite-based observations for assessing global variability in lacustrine phytoplankton blooms;
  • Development of partnerships with other labs on targeted field-based projects for assessing climate drivers of water quality impairments;
  • Assessment of water quality management strategies in terms of their robustness to future changes in climate and, conversely, their potential climate impacts.

The position is based in Dr. Anna M. Michalak’s lab and will involve extensive collaboration with researchers at the other institutions, offering excellent opportunities for joint mentoring and career development.

The Postdoctoral Research Associate will be responsible for identifying innovative strategies for developing a quantitative basis for understanding the impacts of climate on water quality, as well as possible feedbacks with the climate system. While we are interested in site-specific studies, our long-term focus is on developing understanding that is at least in part transferable across systems, such that we can inform processes and variability in poorly sampled regions and at aggregate regional scales.

Position Duties

  • Identify compelling scientific questions, design and conduct high-level research, and collaborate with other members of the Michalak Lab on topics within the broad area defined above.
  • Coordinate with outside collaborators to identify key scientific opportunities and modeling strategies.
  • Lead and contribute to research papers to be published in the peer reviewed literature.

Requirements

  • Ph.D. in hydrology, limnology, remote sensing, earth science, or related field;
  • Experience working with water quantity or quality observations at regional, continental and/or global scales;
  • Experience with quantitative data analysis and modeling approaches;
  • Experience exploring questions about climate and/or water quality;
  • Excellent oral and written communication skills.

Informal inquiries about these positions can be made by emailing Anna Michalak at michalak@carnegiescience.edu.  Formal applications for employment must be submitted by clicking on the bar below, and must include a cover letter, CV, and list of at least three references.

Postdoctoral Opportunity: Optimization of Idealized Near-Zero-Emission Energy Systems

Department: DGE – Global Ecology

Salary: TBD Competitive Salary

Location: Stanford, CA

We seek to understand basic principles relating to how various cost and performance characteristics of energy technologies would affect their penetration in possible future near-zero-emission energy systems. For example, under what conditions would two different battery technologies, one with higher capital costs and round-trip efficiency and another with lower capital costs but lower round-trip efficiency, be able to co-exist in a future energy system and under what conditions would one of these battery technologies drive out the other? Similar questions can be asked about a wide range of technology choices. It is hoped that the understanding gained would inform R&D investment aimed at near-zero-emission energy system innovation, and also help indicate how deployment choices could help maintain optionality and avoid technological lock-in.

Coming from a physical science and engineering cost perspective, and putting aside political and policy constraints, we seek to define an idealized system and then solve it exactly, in the hopes that the conceptual understanding gained will inform decision-making in the real world.

Our initial focus will be on optimization of a schematic model of electricity and fuels sectors. The research will utilize a spatially-unresolved functional model of energy transformations and uses to evaluate different technical solutions for decarbonizing electricity production. Technology options include, but are not limited to: intermittent electricity generation technologies (solar, wind), energy storage (batteries, compressed air, thermal, pumped hydro, power-to-gas-to-power), flexible generation (natural gas w/ and w/o CCS, flexible nuclear, traditional hydro) and baseload generation (nuclear, coal). Electricity and heat to fuels is also of interest, as are demand side components, such as demand management and increases in demand due to vehicle electrification or power-to-fuel transitions, among others. Later analysis could involve extension to explicitly consider spatial dimensions.

A successful candidate will play a major role in planning and executing these techno-economic investigations and communicating the results through peer-reviewed publications and direct engagement with public and private technology investment and policy decision makers.

The position will involve working with Ken Caldeira at the Carnegie Institution for Science Department of Global Ecology and Adam Brandt of the Stanford Department of Energy Resources Engineering on the Stanford University campus.

We maintain an exciting collegial atmosphere, working in a diverse group that includes climate modelers, energy-system analysts, assessment experts, and field researchers. Carnegie Institution post-docs have access to most Stanford facilities.

The initial term will be for one year with the potential for renewal for a second year up to a maximum of four years. Positions are available now and we are flexible with regard to start date.

Candidates with a PhD in engineering or a related scientific or technical field, or comparable experience, are particularly encouraged to apply. Achievement in the area of scientific publication, or comparable evidence of being able to complete high quality work in a timely manner, is a primary filter determining which applications receive greater consideration. Compensation for this position includes a competitive salary and comprehensive benefits.

Informal inquiries about these positions can be made by emailing Ken Caldeira at kcaldeira@carnegiescience.edu and/or Adam Brandt at abrandt@stanford.edu, however formal applications for employment must be submitted by clicking on the blue bar below.

Postdoctoral Research Associate: Exploring Key Factors for a Near-zero Emission Energy Transition

Department: DGE – Global Ecology

Salary: TBD Competitive

Location: Stanford, CA

We are developing a group of collaborating researchers who seek to explore key factors that could help facilitate a transition to a near-zero emission energy system. As the Carnegie Energy Innovation project (http://CarnegieEnergyInnovation.org), we engage in a collection of projects, which postdocs are expected to lead. Our work typically falls into four related areas:

  1. Schematic energy-system modeling
  2. Schematic economic modeling
  3. Geophysical modeling
  4. Energy and climate-related analysis

Examples of current projects include: (1) A schematic energy system modeling effort aimed at understanding the range of potentially feasible near-zero emission energy systems, what would have to become true to make feasible different system architectures, and the value of technical innovation. (2) A schematic economic modeling effort aimed at understanding the role of efficiency improvements in affecting carbon dioxide emissions and economic growth. (3) A geophysical modeling effort aimed at understanding efficacy and possible unintended consequences of regional-scale wind farms. (4) An analysis of factors that would affect the potential climate benefit of possible technological innovations. We are also in the process of organizing an international meeting on balancing climate and development objectives in the poorest countries of the world.

Postdocs are free to work on a broad range of topics within this broad general domain. Examples of such studies published so far this year include: Shayegh et al. (Evaluating relative benefits of different types of R&D for clean energy technologies, Energy Policy, 2017), Cao et al. (Simultaneous stabilization of global temperature and precipitation through cocktail geoengineering, GRL, 2017), Clack et al. (Evaluation of a proposal for reliable low-cost grid power with 100% wind, water, and solar, PNAS, 2017), Wang et al. (Will the use of a carbon tax for revenue generation produce an incentive to continue carbon emissions? ERL, 2017), Ahbe and Caldeira (Spatial Distribution of Generation of Lorenz’s Available Potential Energy in a Global Climate Model, J Clim., 2017).

This position will involve working with Ken Caldeira at the Carnegie Institution for Science Department of Global Ecology on the Stanford University campus. Caldeira has a physical science background, but we are collaborating closely with (and hiring!) people who have deeper experience in energy system and/or economic modeling. Another option would be to work at University of California (Irvine) with Steve Davis as principal mentor (sjdavis@uci.edu).

Successful candidates will play a major role in planning and executing these investigations and communicating the results through peer-reviewed publications and direct engagement with public and private technology investment and policy decision makers. The initial term will be for one year with the potential for renewal for a second year up to a maximum of four years.

Candidates with a PhD in science, engineering or economics, or comparable experience in quantitative analysis, are particularly encouraged to apply. Achievement in the area of scientific publication, or comparable evidence of being able to complete high quality work in a timely manner, is a primary filter determining which applications receive greater consideration. Positions are available now; start date is flexible but Spring or Summer of 2018 would be ideal. Carnegie Institution post-docs have access to most Stanford facilities. Compensation for this position includes a competitive salary and comprehensive benefits.

Informal inquiries about these positions can be made by emailing Ken Caldeira at kcaldeira@carnegiescience.edu.  Formal applications for employment must be submitted by clicking on the bar below, and must include both a cover letter and CV.
