Charles (Chip) Lawrence has been involved in computational biology research since the early 1980's. His research now specifically focuses on the application of Bayesian algorithms that he and his collaborators have developed, leading to biological insights on transcription regulation and identification of regulatory motifs in prokaryotic and eukaryotic sequences, comparative genomics, antisense oligonucleotide and siRNA design, the composition of nucleotide sequences, and detailed analyses of several protein families.
Charles (Chip) Lawrence has been involved in computational biology research since the early-1980s. At a time when research in the field was focused on algorithmic approaches, he was a pioneer in developing novel statistical approaches to biological sequence analysis. In fact, he was one of the first to recognize that the inherent statistical nature of genomic processes and the immense data resulting from genomic sequencing projects could only be fully analyzed by using statistical algorithms.
Of particular note are his contributions to the development of sequence alignment algorithms, specifically through the application of Bayesian statistical methods and the adaptation of a Gibbs sampling strategy to this problem. This accomplishment is clearly demonstrated by his seminal Science paper in 1993 describing the first application of the statistical technique Gibbs sampling to the problem of multiple sequence alignment. Also at the forefront is Chip's research with Ye Ding on Bayesian statistical approaches to RNA secondary structure prediction, yielding predictions on the full ensemble of probable structures that an RNA molecule may adopt.
The past several years of statistical algorithm development by Chip and his collaborators have yielded several widely used programs: the Gibbs Motif Sampler, the Bayes aligner, Sfold, BALSA, Gibbs Gaussian Clustering, and Bayesian Motif Clustering.
Chip's research continues to be focused on the application of Bayesian algorithms that he and his collaborators have developed, leading to biological insights on transcription regulation and identification of regulatory motifs in prokaryotic and eukaryotic sequences, comparative genomics, antisense oligonucleotide and siRNA design, the composition of nucleotide sequences, and detailed analyses of several protein families.
In addition to being at the forefront of research in computational biology, Chip has devoted time to education. He developed a tutorial on Bayesian statistics and Gibbs sampling which he presented at ISMB '97 and '98, as well as to several university audiences. Chip has mentored several young investigators, introducing to this interdisciplinary field not only scientists with backgrounds in statistics, but also scientists with backgrounds in computer science and biology.
