Thirty years ago, Sanger first introduced the gel electrophoresis method for sequencing DNA. Since then, technology has improved to the point where we are adding over 10 billion bases to GenBank each year at a cost of less than 0.1 cents per base. Amazingly, we are now entering an era of even more dramatic sequencing growth thanks to next-generation technologies that will completely dwarf all previous efforts. Although the cost and speed of sequencing will improve by orders of magnitude, the characteristic short read length of such technologies creates new challenges in effectively using the data. In this dissertation, I describe three significant algorithmic contributions I have made for next-generation sequencing: (1) whole-genome short-read sequencing and assembly, (2) bacterial flora-typing using targeted short-read sequencing, and (3) ancestry inference using dense SNP arrays. First, I present SHRAP (SHort Read Assembly Protocol), a sequencing protocol and assembly methodology that uses short-read technologies to decipher complex, mammalian-sized genomes. Our sequencing protocol is based on a variation of hierarchical clone-based sequencing that is optimized for high-throughput implementation using current technologies. We assemble the genome through a series of algorithms that first determines clone ordering in-silico, then performs error correction, and finally assembles localized sets of reads in three stages of hierarchically larger regions. By benchmarking our method on large simulations of the human genome, I demonstrate that it is possible to perform fast and truly inexpensive de novo sequencing of mammalian genomes. Next, I describe the genomic study of microbial communities using next-generation sequencing. I present a methodology for phylogenetic classification based on short, 16S rDNA gene sequence reads and apply the technique to reads obtained via high-throughput Pyrosequencing. I then examine our ability to classify reads at different levels in the phylogeny and discuss limitations of the technique and the effects of read-length and targeting specific 16S variable regions using simulation. Finally, I present HAPAA (HMM-based Analysis of Polymorphisms in Admixed Ancestries), a methodology for inferring the ancestry of chromosomal blocks using dense SNP arrays. I describe how our method improves upon previous techniques by modeling the long-range patterns of haplotypic variation seen in populations due to linkage disequilibrium. Finally, to study the effect of genetic divergence between populations on ancestry inference methods, I will present a testing methodology we devised that constructs synthetic populations and tests on individuals with varied genetic histories. As DNA sequencing technology evolves, it will continue to open up opportunities for new computational approaches for understanding our genetics. The algorithms I present address three such opportunities that exist today with next-generation sequencing.

Computational Methods for Understanding Genetic Variations from Next Generation Sequencing Data

Studies of human genetic variation reveal critical information about genetic and complex diseases such as cancer, diabetes and heart disease, ultimately leading towards improvements in health and quality of life. Moreover, understanding genetic variations in viral population is of utmost importance to virologists and helps in search for vaccines. Next-generation sequencing technology is capable of acquiring massive amounts of data that can provide insight into the structure of diverse sets of genomic sequences. However, reconstructing heterogeneous sequences is computationally challenging due to the large dimension of the problem and limitations of the sequencing technology.This dissertation is focused on algorithms and analysis for two problems in which we seek to characterize genetic variations: (1) haplotype reconstruction for a single individual, so-called single individual haplotyping (SIH) or haplotype assembly problem, and (2) reconstruction of viral population, the so-called quasispecies reconstruction (QSR) problem. For the SIH problem, we have developed a method that relies on a probabilistic model of the data and employs the sequential Monte Carlo (SMC) algorithm to jointly determine type of variation (i.e., perform genotype calling) and assemble haplotypes. For the QSR problem, we have developed two algorithms. The first algorithm combines agglomerative hierarchical clustering and Bayesian inference to reconstruct quasispecies characterized by low diversity. The second algorithm utilizes tensor factorization framework with successive data removal to reconstruct quasispecies characterized by highly uneven frequencies of its components. Both algorithms outperform existing methods in both benchmarking tests and real data.

Repetitive Structures in Biological Sequences Algorithms and Applications

Repetitive Structures in Biological Sequences  Algorithms and Applications

The articles collected in this book provides a glance into the rich emerging area of repeatome research, addressing some of its pressing challenges.

Repetitive structures in biological sequences are emerging as an active focus of research and the unifying concept of "repeatome" (the ensemble of knowledge associated with repeating structures in genomic/proteomic sequences) has been recently proposed in order to highlight several converging trends. One main trend is the ongoing discovery that genomic repetitions are linked to many biological significant events and functions. Diseases (e.g. Huntington's disease) have been causally linked with abnormal expansion of certain repeating sequences in the human genome. Deletions or multiple copy duplications of genes (Copy Number Variations) are important in the aetiology of cancer, Alzheimer, and Parkinson diseases. A second converging trend has been the emergence of many different models and algorithms for detecting non-obvious repeating patterns in strings with applications to in genomic data. Borrowing methodologies from combinatorial pattern, matching, string algorithms, data structures, data mining and machine learning these new approaches break the limitations of the current approaches and offer a new way to design better trans-disciplinary research. The articles collected in this book provides a glance into the rich emerging area of repeatome research, addressing some of its pressing challenges. We believe that these contributions are valuable resources for repeatome research and will stimulate further research from bioinformatic, statistical, and biological points of view.
