For his scientific contributions he was elected fellow or member of prestigious learned bodies like the American Academy of Arts and Sciences, National Academy of Sciences, American Association for the Advancement of Science, Institute of Mathematical Statistics, Celera Genomics and French Acadèmie des Sciences. He was awarded a Gairdner Foundation International Award and the Senior Scientist Accomplishment Award of the International Society of Computational Biology. He currently holds an Endowed Chair at USC and has held numerous visiting positions in major universities. In addition to research, he is actively involved in the academic and social activities of students as faculty master Michael Waterman of USC’s International Residential College at Parkside. Interview of Michael S. Waterman by Y.K. Leong Waterman has served as advisor to NUS on genomic research and was a member of the organizational committee Michael Waterman is world acclaimed for pioneering and of the Institute’s thematic program Post-Genome Knowledge 16 fundamental work in probability and algorithms that has Discovery (Jan – June 2002). On one of his advisory tremendous impact on molecular biology, genomics and visits to NUS, Imprints took the opportunity to interview bioinformatics.

Machine Learning and Statistical Methods for Clustering Single-Cell RNA-Sequencing Data Raphael Petegrosso 1, Zhuliu Li 1 and Rui Kuang 1,∗

Associate Editor: XXXXXXX Received on XXXXX; revised on XXXXX; accepted on XXXXX Abstract Single-cell RNA-sequencing (scRNA-seq) technologies have enabled the large-scale whole-transcriptome profiling of each individual single cell in a cell population. A core analysis of the scRNA-seq transcriptome profiles is to cluster the single cells to reveal cell subtypes and infer cell lineages based on the relations among the cells. This article reviews the machine learning and statistical methods for clustering scRNA- seq transcriptomes developed in the past few years. The review focuses on how conventional clustering techniques such as hierarchical clustering, graph-based clustering, mixture models, k-means, ensemble learning, neural networks and density-based clustering are modified or customized to tackle the unique challenges in scRNA-seq data analysis, such as the dropout of low-expression genes, low and uneven read coverage of transcripts, highly variable total mRNAs from single cells, and ambiguous cell markers in the presence of technical biases and irrelevant confounding biological variations. We review how cell-specific normalization, the imputation of dropouts and dimension reduction methods can be applied with new statistical or optimization strategies to improve the clustering of single cells. -
