Taylor, Mark | Understanding the community based participatory research (CBPR) approach: case study in Ghana | In 2003, the University of Utah, in cooperation with Kwame Nkrumah University of Science and Technology (KNUST), Komfo Anokye Teaching Hospital (KATH), the Atwima Nwabiagya District Assembly and Barekuma community leaders, formed what is known as the Barekuma Collaborative Community Development Proj... | | 2011-12-01 |

Gerig, Guido | Evaluation of DTI property maps as basis of DTI atlas building | Compared to region of interest based DTI analysis, voxel-based analysis gives higher degree of localization and avoids the procedure of manual delineation with the resulting intra and inter-rater variability. One of the major challenges in voxel-wise DTI analysis is to get high quality voxel-level c... | | 2010-01-01 |

Gerig, Guido | Measures for validation of DTI tractography | The evaluation of analysis methods for diffusion tensor imaging (DTI) remains challenging due to the lack of gold standards and validation frameworks. Significant work remains in developing metrics for comparing fiber bundles generated from streamline tractography. We propose a set of volumetric and... | | 2012-01-01 |

Gerig, Guido | Automatic corpus callosum segmentation using a deformable active Fourier contour model | The corpus callosum (CC) is a structure of interest in many neuroimaging studies of neuro-developmental pathology such as autism. It plays an integral role in relaying sensory, motor and cognitive information from homologous regions in both hemispheres. We have developed a framework that allows auto... | | 2012-01-01 |

Gerig, Guido | Changes of MR and DTI appearance in early human brain development | Understanding myelination in early brain development is of clinical importance, as many neurological disorders have their origin in early cerebral organization and maturation. The goal of this work is to study a large neonate database acquired with standard MR imagery to illuminate effects of early ... | | 2010-01-01 |

Gerig, Guido | A framework for longitudinal data analysis via shape regression | Traditional longitudinal analysis begins by extracting desired clinical measurements, such as volume or head circumference, from discrete imaging data. Typically, the continuous evolution of a scalar measurement is estimated by choosing a 1D regression model, such as kernel regression or fitting a p... | | 2012-01-01 |

Gerig, Guido | 3D of brain shape and volume after cranial vault remodeling surgery for craniosynostosis correction in infants | The skull of young children is made up of bony plates that enable growth. Craniosynostosis is a birth defect that causes one or more sutures on an infant's skull to close prematurely. Corrective surgery focuses on cranial and orbital rim shaping to return the skull to a more normal shape. Functional... | | 2013-01-01 |

Gerig, Guido | DTI quality control assessment via error estimation from monte carlo simulations | Diffusion Tensor Imaging (DTI) is currently the state of the art method for characterizing the microscopic tissue structure of white matter in normal or diseased brain in vivo. DTI is estimated from a series of Diffusion Weighted Imaging (DWI) volumes. DWIs suffer from a number of artifacts which ma... | | 2013-01-01 |

Gerig, Guido | Towards analysis of growth trajectory through multi-modal longitudinal MR imaging | The human brain undergoes significant changes in the first few years after birth, but knowledge about this critical period of development is quite limited. Previous neuroimaging studies have been mostly focused on morphometric measures such as volume and shape, although tissue property measures rela... | | 2010-01-01 |

Pascucci, Valerio | Exploring power behaviors and trade-offs of in-situ data analytics | As scientific applications target exascale, challenges related to data and energy are becoming dominating concerns. For example, coupled simulation workflows are increasingly adopting in-situ data processing and analysis techniques to address costs and overheads due to data movement and I/O. However... | | 2013-01-01 |

Gerig, Guido | Characterizing growth patterns in longitudinal MRI using image contrast | Understanding the growth patterns of the early brain is crucial to the study of neuro-development. In the early stages of brain growth, a rapid sequence of biophysical and chemical processes take place. A crucial component of these processes, known as myelination, consists of the formation of a myel... | | 2014-01-01 |

Kuhlman, Brian | PHD Entrepreneur | The idea for this speech began when my friends and family started asking what I would do after graduating with my PhD in psychology. Folks tended to get a bit confused when I replied that my plan is to start a business. You don't need a PhD to do that! It's true. The path leading from PhD to Entrepr... | entrepreneur; PhD; doctoral; industry; academia | 2013-05-03 |

Gerig, Guido | Multivariate longitudinal statistics for neonatal-pediatric brain tissue development | The topic of studying the growth of human brain development has become of increasing interest in the neuroimaging community. Cross-sectional studies may allow comparisons between means of different age groups, but they do not provide a growth model that integrates the continuum of time, nor do they ... | | 2008-01-01 |

Pascucci, Valerio | Characterization and modeling of PIDX parallel I/O for performance optimization | Parallel I/O library performance can vary greatly in re- sponse to user-tunable parameter values such as aggregator count, file count, and aggregation strategy. Unfortunately, manual selection of these values is time consuming and dependent on characteristics of the target machine, the underlying fi... | | 2013-01-01 |

Gerig, Guido | Quality control of diffusion weighted images | Diffusion Tensor Imaging (DTI) has become an important MRI procedure to investigate the integrity of white matter in brain in vivo. DTI is estimated from a series of acquired Diffusion Weighted Imaging (DWI) volumes. DWI data suffers from inherent low SNR, overall long scanning time of multiple dire... | | 2010-01-01 |

Gerig, Guido | Discrimination analysis using Multi-object statistics of shape and pose | A main focus of statistical shape analysis is the description of variability of a population of geometric objects. In this paper, we present work towards modeling the shape and pose variability of sets of multiple objects. Principal geodesic analysis (PGA) is the extension of the standard technique ... | | 2007-01-01 |
