YANA BROMBERG, CO-CHAIR

PROTEIN STRUCTURE AND DATA SCIENCE

Associate professor, Rutgers University

Hans Fischer Fellow, Technical University of Munich

Modern biology increasingly relies on high-throughput techniques. Yana Bromberg’s work utilizes a variety of computational methodologies, including mining of scientific repositories, machine learning methods, and network analysis, to extract as much useful information from these data as possible. In the genomic sense, this primarily implies correlating phenotypic differences with observed nucleotide sequence variations. On the protein side the challenge is to annotate protein function at reasonable accuracy levels. The whole organism level incorporates all types of evidence to annotate evolutionary history and phenotypes. As an overall goal, the Bromberg group is particularly interested in examining the emergent complexity of proteins in microbial ancestors. They are developing new computational methods for linking protein structure to the evolution of function, particularly to redox functionality of metal binding proteins, with the goal of identifying the oldest protein structures and to time the early evolution of folds. The machine-learning tools built for this purpose will also allow identification of trace-element/metal signatures indicative of the various stages of development of life.

ROBERT M. HAZEN, CO-CHAIR

MINERALOGY AND ASTROBIOLOGY

Staff Scientist, Geophysical Laboratory, Carnegie Institution for Science

Clarence Robinson Professor, George Mason University

 

Earth scientist Robert Hazen has an unusually rich research portfolio. He is trying to understand the carbon cycle from deep inside the Earth; chemical interactions at crystal-water interfaces; the interactions of organic molecules on mineral surfaces as a possible springboard to life; how life arose from the chemical to the biological world; how life emerges in extreme environments; and the origin and distribution of life in the universe just to name a few topics. In tandem with this expansive Carnegie work, he is also the Clarence Robinson Professor of Earth Science at George Mason University. He has authored more than 400 articles and 25 books on science, history, and music.

 

As principal investigator of the Deep Carbon Observatory, Hazen oversees the primary mission of work to promote the transformational understanding of the chemical and biological roles of carbon in Earth's interior—a program in part supported by the Sloan Foundation.

 

In work on mineral-molecule interactions, it turns out that the origin of life’s biochemicals have “handedness,” like left and right handiness in people. Hazen and team believe that these so-called chiral mineral surfaces may have played a significant role in the selection and concentration of molecules necessary for life.

 

Although minerals are necessary for essential tasks, science has assumed that the mineral species found on Earth today are much the same as they were during Earth’s first 550 million years—the Hadean Eon—when life emerged. Hazen found this not to be true. He compiled a list of every plausible mineral species on the Hadean Earth and concludes that no more than 420 different minerals—about 8 percent of the nearly 5,000 species found on Earth today—would have been present at or near Earth’s surface.

PETER E. DRISCOLL

TECTONICS AND GEODYNAMICS

Staff Scientist, Department of Terrestrial Magnetism, Carnegie Institution for Science

Dr. Peter Driscoll’s research interests focus on the thermal and magnetic evolution of the Earth. He has worked on the thermal evolution of Earth’s interior, dynamics of the core, polarity reversals of Earth’s magnetic field, magnetic-limited atmospheric escape, coupled surface-interior volatile cycling, the divergence of Earth and Venus, and the internal dynamics and detectability of terrestrial exoplanets.

 

Much of Driscoll's research is driven by the questions: what makes the Earth a unique planet? He says Earth is unique in that it is the only planet that has maintained a strong magnetic field, plate tectonics, and surface liquid water over most, and possibly all, of its history. What is it about Earth’s interior that has allowed these complex phenomena to occur? How do they work? Are they connected in any way?

 

Driscoll will use large-scale numerical simulations to investigate the coupling of the mantle and core, and explore how this coupling is manifested in paleomagnetic and tectonic observations. In particular, he will investigate how the evolution of the geodynamo over the last 500 million years is related to convective cycles in the mantle, the growth of the solid inner core, and changes in rotation. He plans to investigate the process of magnetic polarity reversals by comparing numerical dynamo simulations to geomagnetic observations and to push towards more realistic Earth-like dynamo simulations. He will investigate the dynamics of rocky exoplanets by coupling internal and orbital evolution models to make predictions for their detectability.

DONATO GIOVANNELLI

MICROBIAL ECOLOGY, GEOBIOLOGY, AND METAGENOMICS

EON Research Fellow, Earth-Life Science Institute and Rutgers University

Donato Giovannelli is a Microbial Ecologist working on the microbiology of extreme environments. His primary research interest is in the co-evolution of the biosphere and the geosphere and on how life influences planetary-scale processes. His current research is focused on two related themes: 1) the metabolic and taxonomic diversity of prokaryotes in different extreme ecosystems; and 2) the emergence and evolution of early metabolism. These diverse interests stem from three basic assumptions underlying his research: i) prokaryotes dominated the evolutionary history of our planet; ii) they are responsible for the bio in biogeochemistry both at the ecosystem level and through time; and iii) extremophilic prokaryotes living in extreme environments resembling early Earth analogs, despite being extant organisms, retain a higher number of ancestral metabolic traits. In his work, Donato Giovannelli combines classic microbiology techniques with data from comparative genomic, phylogenetic, and environmental surveys and computational approaches to reconstruct geo-bio interactions.

 

Donato Giovannelli currently holds an appointment as a joint EON Research Fellow at the Earth-Life Science Institute, Tokyo and Rutgers University, USA, he is a Visiting Scholar at the Institute of Advanced Studies in Princeton, USA, and an Adjunct Researcher at the National Research Council of Italy.

ELI K. MOORE

GEOBIOLOGY, PROTEOMICS, AND METAGENOMICS

 

AAAS Science and Technology Policy Fellow, US Department of Agriculture

Rowan University

Dr. Moore is an American Association for the Advancement of Science (AAAS) Science and Technology Policy fellow working at the USDA - Agricultural Research Service on enhancing data intensive research within the USDA.  

Previously Eli was a postdoctoral research associate at Rutgers University working with Paul Falkowski on understanding the coevolution of the geosphere and biosphere. He is particularly interested in Earth surface redox state on the availability of crucial metallocofactors and the evolution of metabolic pathways in the Archean Eon. Through this work Dr. Moore and colleagues have constructed a primitive network of biological electron transfer which gave rise to the Great Oxidation Event (GOE) and the evolution of specialized multicellular organisms. He is now building data resources to link this network of electron transfer to protein structure evolution in deep time and in modern environments. 

Eli’s past work focused on tracking the longevity of algal proteins in the water column and sediments as part of the greater carbon and nitrogen cycles, and discovering new membrane lipid structures using high resolution mass spectrometry and nuclear magnetic resonance (NMR).

KARYN L. ROGERS

DATA SCIENCE AND MICROBIAL ECOLOGY

Assistant Professor, Rensselaer Polytechnic Institute

 

Dr. Rogers’ research focuses on the relationships between environmental conditions and life’s emergence and survival, and is broadly applied to understanding the origin of life on Earth, the potential for life throughout the solar system, and the extent of life in extreme environments. Dr. Rogers’ research program includes field research in early Earth and Mars analog environments and modern extreme ecosystems, geochemical modeling of abiotic synthesis and microbial metabolism in extreme environments, as well as experimental laboratory studies that emphasize true replication of environmental conditions. The driving question is how realistic environmental conditions combine to form habitable niches that can both support the early emergence of life as well as the long-term survival of life in these environments.

 

Dr. Rogers’ fieldwork includes several terrestrial hydrothermal systems, shallow marine hydrothermal system, and modern deep-sea mid-ocean ridge environments. These field endeavors are combined with laboratory experiments to develop a holistic picture of functional microbial ecosystems. Furthermore, cultivation of microbial communities at high-pressure conditions is extending our understanding of habitability in subsurface conditions on Earth as well as the subsurface oceans of Icy Worlds. Additionally, Dr. Rogers’ group is exploring the abiotic synthesis and stability of prebiotic biomolecules over a range of realistic early Earth conditions. Faithful replication of in situ conditions, including temperature, pressure, fluid chemistry, and mineralogy, fosters the development of origins of life scenarios that focus on experimental and environmental conditions that are both possible for prebiotic synthesis as well as plausible on early Earth.

 

Dr. Rogers is the US Lead for the Deep Carbon Observatory’s PRIME (Piezophile Research Instrumentation for Microbial Exploration) Facility, is Associate Director of the New York Center for Astrobiology at RPI, and joins Peter Fox as co-Lead for the DCO Data Science team.

AUBREY L. ZERKLE

GEOBIOLOGY AND BIOGEOCHEMISTRY

Reader, University of St Andrews

 

Dr. Aubrey Zerkle is a Reader in the School of Earth & Environmental Sciences at the University of St Andrews, and a PI of the inter-disciplinary Peter James Clarke Centre for Philosophical Geobiology. Her research focuses on understanding the co-evolution of life with Earth and other planetary environments over geologic timescales. She utilizes a multi-disciplinary approach, including stable isotope geochemistry, microbiology, nutrient and trace metal analyses, to examine these interactions and possible feedbacks in modern and paleo-environments.

 

Current research in Dr Zerkle’s group centers around three broad areas:

1. Investigating feedbacks between the geosphere, atmosphere, and biosphere during important transitions in Earth history, including the Great Oxidation Event, Periodic Haze Events, and mass extinction events;

2. Examining biogeochemical cycling in extreme environments that act as modern "analogues" to ancient Earth and exoplanetary systems (e.g., sulfidic and acidic environments);

3. Establishing and evaluating stable isotope biosignatures for microbial activity, on Earth and beyond.
