Research Statements

Field of Interest

“Computational science” involves the innovative and essential use of high-performance computation, and/or the development of computational technologies, to advance knowledge or capabilities in a scientific or engineering discipline. Please describe how computational science will spur advances in your particular area of scientific or engineering interest. Reserve discussion of your specific thesis research for later essays.

essay

Integrating Geographic Information Systems (GIS) and multi-scale modeling to simulate and evaluate the geographic placement of bioenergy crops at the national scale promises to provide new insights for long-term national energy security and sustainable biomass-based bioenergy production.

However, this integration approach requires an enormous amount of computation and storage resources and an innovative computational science approach to tackle the complexity of multi-scale modeling and handle the significant quantity of spatio-temporal data required to support and facilitate the modeling (e.g. land use, environmental conditions, and ecological processes).

Computational geography will enable the utilization of simulation models to evaluate large-scale land use scenarios not only for arable crops (e.g. corn and soybeans), but also next-generation bioenergy crops (e.g. miscanthus and switch grass). Fine-grained simulations at the national scale will support the evaluation of optimal land use strategies for sustainable bioenergy production. The impact of advancing computational geography to develop the aforementioned approaches is significant in addressing a practical issue of rapidly growing U.S. national priority.

Program of Study

The fellowship program of study requirement is designed to give you a breadth of competency in fields outside your own that will enhance your ability to perform computational science research. Please describe how you expect that the courses listed in your planned program of study outside your chosen discipline will contribute to your own research in the future. Max words is 300

essay

The courses in my Program of Study are assembled to enhance my knowledge in the fundamental computational science theories and methods and to further improve my ability to integrate GIS, multi-scale modeling, and high-performance computing to gain the understanding of bioenergy sustainability.

Applied Linear Algebra covers essential topics such as matrix operations and transformations, and provides the applied mathematical utilities required to develop GIS and modeling implementations. Techniques and methods learned in ‘Statistics and Probability I’ will be necessary to calibrate and validate models and analyze the accuracy of the findings, because computational models are commonly based on probability assessment and randomness principles. Building on the knowledge acquired in linear algebra, ‘Introduction to Numerical Analysis’ will introduce topics to help evaluate and improve model quality. This course also teaches the mathematical theories for commonly used techniques in computational geography that will enhance my domain knowledge.

The ‘Introduction to Parallel Programming’ course will extend my parallel computing knowledge and help me understand the techniques to build parallel multi-scale models. In addition, I will benefit from the performance evaluation topics of this course in terms of developing petascale computational methods in my research. Algorithms will strengthen my foundational knowledge in various numerical and GIS algorithms. The knowledge gained in both of these courses will be important to help develop efficient and scalable multi-scale models.

High-Performance Computation and Research

One of the major sources of supercomputer time to support scientific research and discovery is the DOE's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program (see http://www.nersc.gov/projects/incite/). INCITE designates large chunks of supercomputer time and data storage space – as much as 18.2 million supercomputer processor-hours total and hundreds of terabytes of disc space – for computationally intensive, large-scale research projects. It is not designed to merely shorten the time for a simulation or experiment. Rather, researchers use the supercomputer resources to conduct novel and highly detailed simulations of physical, chemical and biological structures and phenomena. The program provides the cycles necessary to produce major discoveries in a broad range of fields.

In 300 words or less, outline how you would make a case for access to high performance computing through a program like INCITE in order to impact your own research.

essay

Biomass energy is recognized as a major energy source to meet the future energy demand and to simultaneously decrease greenhouse gas emissions. Though crop biomass production on a regional scale has been studied for decades, current modeling frameworks cannot meet the challenge of identifying crop biotechnology targets and best agricultural practices to further increase sustainable biomass production.

Optimizing crop placement strategies while constrained by environment, economics, and transportation requirements will improve the development of sustainable biofuels. Multi-scale fine-grained simulations integrated with GIS can play a key role in optimizing land-use strategies to increase bioenergy production efficiency by simultaneously considering the impact of various economic, ecological and environmental factors.

Such an integrated approach based on GIS and multi-scale modeling requires massive storage and computational resources such as those provided by the INCITE. Spatially-explicit modeling from the levels of the individual plant competing for resources to the entire U.S. is extremely computationally intensive. Adding to the computational intensity, spatio-temporal environmental data (e.g. climate, soil, terrain, and water) is crucial to calibrate and validate multi-scale models.

In summary, my Program of Study will be enabled by INCITE-like supercomputing resources to synthesize and analyze massive geospatial data (Shook et al. 2007), and empower large-scale fine-grained simulations integrated with GIS. This study promises to have a significant impact on the state of the art knowledge of sustainable bioenergy that will become very important to our national energy security.

Program of Study

The Program of Study (POS) must contain coursework in three areas: a scientific or engineering discipline, computer science and applied mathematics that will be completed prior to the third year of the fellowship (Exception: Students who begin their doctoral studies coincident with the award of this fellowship will have three years to complete their POS; at least one course in each disciplinary area must be completed within the first two years of the fellowship.) Both graduate coursework and undergraduate coursework that will be granted graduate credit in your home department are acceptable for the POS. (POS example). An important factor in reviewing your application is the extent to which your program of study satisfies the objectives of the fellowship program. Submission of the POS constitutes an explicit commitment to take the courses that meet the requirements of the program description. Catalogue course descriptions are required.
