Michael Duff Assistant Professor in Residence Department of Genetics and Genome Sciences UConn Health Center Institute for Systems Genomics University of Connecticut 400 Farmington Ave Farmington CT 06030 moduff@gmail.com ***As of December 2018, I am with the Fred Hutchinson Cancer Research Center*** in sunny Seattle WA, conducting research on B-cell receptor repertoire dynamics in response to infection and vaccination. moduff.github.io Research directions: Machine Learning, Bioinformatics/Computational Biology/Computational Genomics, Reinforcement Learning Theory, Bayesian methods, Applied Statistics/Mathematics, AI, Deep-Learning & LLMs, Optimization and Operations Research. My efforts in the Graveley Lab have been directed toward bringing computational approaches, statistical modeling methods, and bioinformatics tools to bear upon problems posed by the analysis of Next-Generation-Sequencing (NGS) data, including the standard repertoire of techniques drawn from computational genomics: genome assembly, sequence alignment, gene-expression analysis, motif finding, SNP and structural-variant detection, phylogenetic analysis, and identification of regulatory sequences and networks---as well as the development of special-purpose ad-hoc computational tools for particular applications and novel techniques for data visualization.
