Eriksson is the Director of Education and Outreach for UNAVCO, Boulder, Colorado and serves as a staff member on the Education and Outreach committee for EarthScope.  Eriksson is interested in improving access to scientific data for students at various levels.  She is the Project Director for the NSF-funded summer research internship program RESESS (Research Experiences in Solid Earth Science for Students).  Eriksson was an Associate Professor in Geology at Virginia Tech for 22 years and has a PhD in geochemistry from the University of the Witwatersand in South Africa.  Eriksson is co-author of the recent EOS article Geodesy in the 21st Century (May 2009) which gives an overview of modern applications of space geodesy. 


imageDebi Kilb is currently holds a joint appointment at Scripps Institution of Oceanography (SIO):  she is the Science Director of the SIO Visualization Center and also a SIO Project Scientist with a specialty in seismology.  Her current research has an emphasis on understanding the underlying source physics of earthquakes and how one earthquake can influence another. She is also active in interdisciplinary studies that include numerous, and often disparate, datasets that must be combined in a manner comprehensible and accessible to a wide range of scientists.  To overcome this hurdle, she and her colleagues use interactive three-dimensional (3-D) computer visualizations as a primary tool for examining and communicating the results of scientific studies.  Debi also participates in over 50 education/outreach programs each year, including the annual SIO Earthquake Education Workshop for 6th grade teachers.  She holds a BA in Mathematics/Computer Science from UCSD, a Masters in Mathematics from UCLA and a Ph.D. in Geophysics from the University of Memphis.  She completed a 2-year post-doc at Princeton University before coming to SIO in 2001.

imageKarin Kirk is a geoscience content developer at the Science Education Resource Center (SERC) at Carleton College and an adjunct faculty at SUNY Empire State College. Her SERC work focuses on developing and managing a rich network of educational web sites about pedagogic methods and teaching geoscience. She has authored a wide variety of web sites addressing aspects of geoscience education including the use of data, visualizations and models, the affective domain in teaching geoscience, and a suite of visualization collections for use in teaching geoscience topics.  She has assisted in convening workshops on topics ranging from hurricanes and climate change to teaching about energy.  For SUNY, she teaches online courses in environmental geology and climate change, and prior to that she taught at Skidmore College.  She received her Master’s degree in hydrogeology from Montana State University in 2002.

imageKai Lin is a Programmer Analyst at the San San Diego Supercomputer Center.  He has a Ph.D. in Computer Science from the University of California, San Diego.  Dr. Lin’s current research interests include databases, data management, cyberinfrastructure, geoinformatics, and software engineering.


imageChris Miller is an Assistant Professor of Library Science/Geographic Information Systems Specialist at Purdue University Libraries in West Lafayette, IN.  His position there is conceived less as a traditional academic librarian concerned with collections and reference, and more as an element in the research objectives of the University. His work on interdisciplinary collaborative projects is meant to inject professional-level data stewardship and resource discovery (i.e. library science) into initiatives and projects that might otherwise have left such concerns to afterthought or no thought at all. Currently this work is contributing to IsoMAP, an NSF-funded project to web-mobilize spatially-explicit isotope tracer models; Isee, a USDA-funded education program to deploy soil and other environmental data to a rich web application for classroom use; and Vulcan, a NASA- and DOE-funded project to develop and distribute a high-resolution carbon emissions inventory, among other more library-centric projects.  Miller attended the CSIG in 2007, and took what he learned back to Purdue to design and deliver a Geoinformatics course (Spring 2008, scheduled again for Spring 2010).  This has helped inform and situate both his approach to faculty at Purdue and Library services currently in development. Miller received his M.L.S. from the University of Iowa’s School of Library and Information Science.


imageJohn Moreland is a senior Visualization Scientist at UCSD’s San Diego Supercomputer Center (SDSC). He specializes in scientific visualization, 3D computer graphics programming, and software/hardware design for advanced display systems. He has been an inventor on patents for advanced computer display systems. He has co-authored several books on the Virtual Reality Modeling Language (VRML), and has published numerous peer-reviewed technical papers on a wide variety of subjects in the field of computer science.  John has taught scientific visualization, advanced code optimization, and on many other technical topics at conferences worldwide including SIGGRAPH, Supercomputing, Internet World Asia, and Web Developers. He has also lectured for classes at UCSD, UT-Austin, UCSC, Hong Kong City Polytechnic, NASA/JPL, Cadence Design Systems, and many other venues.


imageDavid Nadeau is a computer scientist at SDSC/UCSD where he specializes in scientific and information visualization.  His animation work visualizing nebula is part of several planetarium shows, and his software tools have been used to visualize data from differing fields as microbiology to geoscience.  Written together with John Moreland, he has two published books on 3D computer graphics.  Nadeau has a Ph.D. from UCSD in Computer Engineering.

Viswanath is the technical lead for the OpenTopography Portal which provides integrated access to high-resolution topographic data and web-based processing tools. He also currently works on a project entitled “Performance Evaluation of On-Demand Provisioning of Data Intensive Applications” which will focus on evaluating the performance of alternative solutions using parallel database technology versus the Hadoop environment using high-resolution topographic data sets from airborne LiDAR surveys as the reference. He is affiliated with the CloudStor Group at SDSC which engages in research and development related to data intensive cloud computing.


imageFabian Walter is a postdoctoral scholar at the Scripps Institution of Oceanography, working under Professor Helen Fricker.  His current research is concerned with seismic activity during glacier calving. To this end, he is analyzing seismic data from tidewater glaciers in Alaska, Antarctic ice shelves and small Alpine mountain glaciers.  Previously, Dr. Walter investigated seismic activity connected to the drainage of a glacier-dammed lake in southern Switzerland. During that project he characterized seismic events accompanying fracture processes in glacier ice and tied the results to the glacier’s response to the lake drainage.  Dr. Walter received his PhD from the Swiss Federal Institute of Technology.
