	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.

	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.
	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.

	Nicola Tisato Are rocks elastic? Not really... especially when saturated with multi-phase fluids. Did you know that a seismic wave is able of mobilizing the liquid saturating rocks and that such a process reduces the seismic wave strength? Yes, this phenomenon, called Wave-Induced-Fluid-Flow could be used to improve subsurface imaging. How? The absorption of elastic energy varies with frequency, this means that certain frequencies are attenuated and other maybe not. Why is this important? Well, adding information about frequency to a seismic signal is like adding colour to a picture....(Under construction)

	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.
