    I am the direct supervisor for the Planetary Environments Laboratory at NASA's Goddard Space Flight Center. I directly oversee over a dozen civil servant scientists, and a total of over 50 researchers and engineers. The focus of our organization is spectroscopy of other worlds. We design, build, fly, and model and analyze data from spectrographs. These observations are of planets in and beyond our Solar System. In this role, I also work to improve the culture of our branch, and the larger institutions it is a part of. In particular, I am dedicated to improving the diversity, inclusivity, and sense of belonging in these organizations. This management role occupies half of my work efforts.

    In my research role, I bring study astrobiology, Earth systems science, and comparative planetology. Most of this work is done by the amazingly talented early career researchers I collaborate with, who span career stages from high school interns through postdocs and research scientists. The diverse, interdisciplinary team that I co-mentor with Dr. Giada Arney and Dr. Ravi Kopparapu simulates the atmospheres of other worlds, including those of ancient Earth, modern Mars, ancient Mars, and exoplanets. We use outputs from those simulations to interpret data from some of Earth’s most ancient rocks, from the Mars Curiosity rover, and to simulate the capabilities of future space-based telescopes designed to look for life on exoplanets.

    The work this team has done has provided me with tremendous opportunities to serve on multiple interdisciplinary research and mission teams, including the Curiosity science team, the HabEx Science and Technology Definition Team (STDT), the Exoplanet-Starshade Probe Misscion Concept STDT, the Large UV-Optical-Infrared Surveyor (LUVOIR) Study Office, the Virtual Planet Laboratory (VPL), and the Resolving Orbital and Climate Keys of Earth and Extraterrestrial Environments with Dynamics (ROCKE-3D) team. I'm also involved in the leadership of the Nexus for Exoplanet Systems Science.

    Finally, I'm passionate about science communication, and believe it is our responsibility as publicly-funded scientists to bring the results of our research back to the public. To this end, I've helped organize FameLab events in the US... and am always looking for new opportunities to talk about NASA science in public forums.

    https://www.quantamagazine.org/20160202-scientists-debate-signatures-of-alien-life/

    This is an article in Quanta Magazine that discusses the complexities associated with the search for life on exoplanets. It starts with a description of the moment when I realized that O3 can build up on planets without life, in certain circumstances. You can see the paper that I published on that subject here.

    Research Interests

    Rocky Extrasolar Planet Characterization

    Our team is currently working on three aspects of terrestrial-sized extrasolar planet characterization:

    1.) the potential for "false positives" and "false negatives" for life to misinform our spectral analyses of these objects,

    2.) the degree to which we can constrain habitability of known or candidate extrasolar planets with current measurements, and prioritize future observations, and

    3.) mission/instrument design for exoplanet characterization.

    The tools we use for this are a series of models of the atmospheres of other planets, the spectra those planets produce, and the imaging of those spectra by exoplanet missions. The atmospheric models are what I spend most of my time developing. In the past, most of this work has been done as part of the Virtual Planetary Laboratory, using their 1-dimensional, altitude-dependent atmospheric models, but we are also partnering with the Goddard Institute for Space Science to develop a planetary 3D GCM based on their Earth GCM, ModelE.

    Modeling Archean Geochemical Proxies

    I am interested in using atmospheric models (photochemical and climatological) to recreate signals observed in the Archean rock record - a time period on Earth when there was life but no molecular oxygen (O2) in the atmosphere. This work will improve our understanding of the evolution of life on Earth, and inform our search for life on other planets as we learn more about the "most alien biosphere" we currently  have data on.

    This work is being done as part of the Virtual Planetary Laboratory, a lead node of the NASA Astrobiology Institute. Specifically, I'm working on the second task of that team, to "Characterize the Environment, Habitability and Biosignatures of the Earth Through Time." We want to uncover the history of biological metabolisms (e.g., methanogenesis, oxygenic photosynthesis, etc.) on the planet, and leverage that knowledge to simulate the biosignatures of the biosphere for different metabolic eras in the planet's history. This will give us a wider set of examples for the biospheres we can look for on extrasolar planets.

    The reason to focus on early Earth as an example of an extrasolar biosphere is that we have a rock record with which to constrain our conceptual and numerical models. The data in the rock record I find most useful are isotopic proxies, which can deliver a tremendous depth and breadth of information about early Earth. My role in the interpretation of these proxies is to propose hypotheses that can explain as many data sets as possible, and use atmospheric models to test whether the hypotheses can explain the data given reasonable boundary conditions. Ideally, we also use model outputs to propose new geological proxies to look for in tests of the hypotheses.

    Molecular Modeling of Astrobiologically-Significant Chemical Reactions

    This is a line of work that has lied dormant for a few years, but that I would be interested in reviving with the right collaborations or student or postdoctoral fellow in our group. In this research, we would utilize molecular modeling tools such as density functional theory to explore the reaction rate constants, equilibrium constants, and reaction pathways for chemical reactions of astrobiologal significance. For example, we could examine reactions that are relevant to the chemistry of planetary atmospheres, the production and preservation of isotopic proxies in the Earth's most ancient rocks, or the habitability of environments on other worlds.

    Brief Bio

    I am the direct supervisor for the Planetary Environments Laboratory at NASA's Goddard Space Flight Center. I directly oversee over a dozen civil servant scientists, and a total of over 50 researchers and engineers. The focus of our organization is spectroscopy of other worlds. We design, build, fly, and model and analyze data from spectrographs. These observations are of planets in and beyond our Solar System. In this role, I also work to improve the culture of our branch, and the larger institutions it is a part of. In particular, I am dedicated to improving the diversity, inclusivity, and sense of belonging in these organizations. This management role occupies half of my work efforts.

    In my research role, I bring study astrobiology, Earth systems science, and comparative planetology. Most of this work is done by the amazingly talented early career researchers I collaborate with, who span career stages from high school interns through postdocs and research scientists. The diverse, interdisciplinary team that I co-mentor with Dr. Giada Arney and Dr. Ravi Kopparapu simulates the atmospheres of other worlds, including those of ancient Earth, modern Mars, ancient Mars, and exoplanets. We use outputs from those simulations to interpret data from some of Earth’s most ancient rocks, from the Mars Curiosity rover, and to simulate the capabilities of future space-based telescopes designed to look for life on exoplanets.

    The work this team has done has provided me with tremendous opportunities to serve on multiple interdisciplinary research and mission teams, including the Curiosity science team, the HabEx Science and Technology Definition Team (STDT), the Exoplanet-Starshade Probe Misscion Concept STDT, the Large UV-Optical-Infrared Surveyor (LUVOIR) Study Office, the Virtual Planet Laboratory (VPL), and the Resolving Orbital and Climate Keys of Earth and Extraterrestrial Environments with Dynamics (ROCKE-3D) team. I'm also involved in the leadership of the Nexus for Exoplanet Systems Science.

    Finally, I'm passionate about science communication, and believe it is our responsibility as publicly-funded scientists to bring the results of our research back to the public. To this end, I've helped organize FameLab events in the US... and am always looking for new opportunities to talk about NASA science in public forums.
