	Matthew A Brown Brown's primary research goal is to develop a more thorough understanding of how past and future treatments affect specimens as sources of data, and the impact these treatments have on the science of paleontology. This approach examines how historic and current practices in the field, laboratory, and collections interplay, and how the scientific community interprets these results in the literature. He also studies how such events foster an evolution of best practices, policy, and law, and he advocates for fossils on public lands. Brown is an active member of the Society of Vertebrate Paleontology and the Society for the Preservation of Natural History Collections, and is the founder and Past-President of the Association for Materials and Methods in Paleontology.

	Elizabeth J Catlos My primary research focus is [bold]geochemistry[/bold], and how the fundamentals of chemistry (mineral reactions, radiogenic and stable isotopes, major and trace elements) can be and are used to understand what the Earth was like in the past. In this, I have interests that span a broad range of range of plate boundary processes and laboratory approaches. Many ancient fault systems are clues to determine the evolution and migration of Earth's continents in the past, identify important economic resources that formed during specific times in Earth's history, and/or to assess geological hazards that result due to reactivation of older faults or mass movement of rocks. They are used to understand how plate tectonics operates today and how it operated in the past. I am interested in constraining the evolution of a number of fault systems and mountain ranges that formed during the closure of ancient ocean systems primarily across Asia, the Middle East, and Europe. For example, a major portion of my [bold]Himalayan research [/bold] agenda involves constraining past motion on the Main Central Thrust, a large-scale shear zone that worked to create the highest mountains on the planet. I currently use novel geochemical and geochronological approaches that take advantage of modern-day technology to understand how [bold] garnet-bearing rocks [/bold] moved at a high-resolution scale within that structure. Garnets are chemical tape recorders, and their chemical elements can be used to ascertain the pressures and temperatures they experienced. They also enclose radioactive minerals, such as monazite, that can be dated to time their history. Data from numerous garnet-bearing rocks across the Main Central Thrust can be used to inform us regarding how and when the Himalayas uplifted in the past, and lend insight into the motion that affects it today. To this end, I collaborate and learn from other researchers, such as geophysicists and modelers. I apply similar approaches to garnet-bearing rocks found in extensional systems in western [bold]Turkey[/bold]. In this region, the plate boundary experienced a major switch in the geological past from compression to extension. Again, I apply new approaches in the thermodynamic modeling and geochronology to garnets in this locale to understand why and how this plate tectonic transition occurred. In this portion of my research, I also include the study of [bold]granites[/bold], as these igneous bodies emplaced during the extensional phase. The timing of their formation is key pieces of information regarding how extension occurred in western Turkey, both in time and space. To this end, I pioneered new imaging approaches to their study, and collaborate with economic geologists in Turkey who are interested in how heat and fluid flow around these granite bodies are intricately involved in the formation of ore resources. Their research sparked my interest in granite petrology, and I also study this rock type in China and Slovakia. Some of these granites formed at ancient plate boundaries as continents collided, and their ages and chemistry constrain when and what types of geological processes operated during their formation. The approaches I apply (geochemistry and geochronology) are of interest to a wide variety of researchers, so I collaborate and involve students in projects that include other geologists. An example of this is the dating of radioactive minerals from [bold]ancient meteorite impact craters and massive volcanic eruptions[/bold], events that are key for shaping how life evolved in Earth's history. These projects involve the use of modern and ever-evolving [bold]technological advances in geochemistry[/bold], such as the laser ablation of tiny zircon crystals, or the use of instruments that do not require minerals to be separated from rocks, such as secondary ion mass spectrometry (SIMS). I am interested in [bold]accessory minerals[/bold], such as zircon and monazite, and what controls their appearance in metamorphic and igneous rocks. Monazite, in particular, has been a focus of my research and I have key expertise in its formation, composition, geochronology, and its use as a rare earth resource. Although my research primarily involves compressional and extensional plate boundaries and igneous and metamorphic rocks, I recently delved into understanding sedimentary rocks from along the North Anatolian Fault, a major strike-slip system in north-central Turkey. In this research, we obtained oxygen isotopes across transects along calcite-filled fractures in limestones using SIMS. These calcite-filled fractures have the potential to record their source and provide key insight into the history of the limestones as well as their use for recording modern day fluid flow driven by seismic activity along the active fault system. Fundamentally, my research is [bold]field-based[/bold] and involves the mapping and collection of rocks and understanding their importance in addressing research questions regarding what the Earth was like in the past. The research is [bold]laboratory-based[/bold], and I take advantage of modern advances in technology applied to geosciences, including numerous facilities at UT Austin and elsewhere.

	Richard J Chuchla Graduate studies were focused on igneous processes, magmatism and related formation of ore deposits. Professional career included exploration for base and precious metal ore deposits, coal assessment and development, and research, exploration and development in the upstream sector of the oil and gas business. Managerial positions led to development of skills in commercial analysis, strategic planning and valuation. Concurrently, led numerous teams negotiating new contracts which led to a strong grounding in analysis of fiscal regimes and petroleum contracts. Familiar with many of the world's basins and experienced in both conventional deepwater and unconventional resources. Remain very interested in the technology of extractive industries and related commercial and policy issues. As Director of the Energy and Earth Resources graduate program, my personal learning objective is to broaden and deepen my understanding of renewable resources. Have a personal passion regarding the workings of the creative process and how it is impeded. Wrote a widely read internal company newsletter called Creative Contemplations.

	Patrick Heimbach Heimbach's research group (Computational Research in Ice and Ocean Systems -- CRIOS) in ICES is engaged in a number of projects, with main funding from NASA, NSF, DOE, and DARPA. [bold](1)[/bold] Our overarching research focusses on understanding the global ocean circulation, its role in climate variability and change, and its predictability on seasonal to decadal time scales. As part of the NASA-funded "Estimating the Circulation and Climate of the Ocean" (ECCO) consortium involving colleagues at JPL, MIT, AER and Scripps, we are synthesizing much of the available satellite and in-situ observations with a state of the art global coupled ocean general circulation model by means of optimal state and parameter estimation. Results are used to infer, for example heat and freshwater content changes over the last few decades, and their impact on global sea level (via the NASA Sea Level Change science team). Related NASA-funded efforts focus on interpreting measurements from the existing and forthcoming GRACE (Gravity Recovery and Climate Experiment) and SWOT (Surface Water and Ocean Topography) satellite missions in deciphering key dynamical processes in the ocean. [bold](2)[/bold] As part of an NSF-funded project (Arctic & subpolar gyre State Estimate -- ASTE), we are developing computational frameworks for quantifying the role of the ocean in observed Arctic climate variability and changes over the last few decades. The framework also enables assessment of how to build an improved observing system in support of the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). [bold](3)[/bold] Our group is also investigating the ocean's role in the observed increasing mass wastage from the two polar ice sheets. Two NSF-funded projects focus on quantifying Greenland ice sheet-ocean interactions (GRISO). In particular, an NSF Research Coordination Network (RCN) project is conducted in collaboration with Co-PI Catania (DGS/UTIG) and other collaborating institutions to improve interdisciplinary data access, standardization and curation through modern cyberinfrastructure in support of GRISO. For another NSF-funded project (East Antarctic Grounding Line Experiment -- EAGLE) led by DGS/UTIG PI Blankenship, our group is developing a framework for conducting simulations of ice-sheet ocean interactions in East Antarctica in conjunction with the planned field campaign designed by UTIG. [bold](4)[/bold] Optimal control methods play an important role in initializing geophysical models, which are constrained by sparse observations in space and time, for the purpose of prediction. As part of the DOE project PISCEES (Predicting Ice Sheet and Climate Evolution at Extreme Scales), we are collaborating with Co-PI Jackson (DGS/UTIG) to develop concepts for adjoint-based transient ice sheet model calibration, initialization for prediction, and uncertainty quantification. Applications have targeted some of the fastest evolving ice stream-shelf systems in the Amundsen Sea Embayment, West Antarctica. [bold](5)[/bold] As part of DARPA's Positioning System for Deep Ocean Navigation (POSYDON) program, we are collaborating with BAE Systems in the project "Networked Estimation of Position using Tomography, Undersea-Gliders, Nudging and Exfiltration" (NEPTUNE). Our role is the provision of optimal ocean states via data assimilation for improved acoustic propagation. Climate change
	Mark A Helper Dr. Helper is a field geologist, a generalist whose interests span igneous and metamorphic petrology, structural geology, tectonics, mineralogy and planetary field geology. His current research explores geochemical and isotopic similarities of Proterozoic and Archean crust in East Antarctica and the southwestern U.S., the Precambrian geology of Texas, and the origin of epidote blueschists in the Klamath Mountains of northern California. Recent senior honors theses under his supervision have examined the mineralogy of Texas topaz, hydration and textural patterns in Balmorhea blue agate, and the distribution and origin of joints in the Hueco Tanks syenite. Working with NASA colleagues, he is also involved in analog planetary field research that examines the utility and efficacy of robotically gathering field data, both as a prelude to and follow-on to human geologic field work on the Moon and Mars. As co-chair of FEAT (Field Exploration and Analysis Team), he helped develop a new curriculum for the geological field training of astronauts and currently co-leads NASA's astronaut field geology training exercises. He also teaches field mapping techniques to NASA engineers and scientists who are developing capabilities for exploring the surface of asteroids, the Moon and Mars.

	Harm J Van Avendonk Van Avendonk is an active-source seismologist who specializes in the acquisition and inversion of seismic refraction data on land and at sea. Often these seismic refraction data are used for a tomographic inversion. The resultant seismic velocity models help us to interpret the composition of the Earth’s crust and mantle, the geometry of sedimentary basins, and the structure of plate boundaries.
