Dr. Pratheepa Jeganathan: R/Bioconductor for Molecular microbial data analysis

For the July 12 edition of our R-Ladies Dallas webinar series, we are excited to welcome Dr. Pratheepa Jeganathan as our guest speaker. Dr. Jeganathan will share how she is using R and Bioconductor packages for molecular microbial data analysis.

Session title: Molecular microbial data analysis
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Abstract: High-throughput sequencing generates massive molecular microbial datasets that pose several statistical challenges. As a result, statistical methods have been developed to address contamination sequences from reagents, unequal sampling, unbounded and undetected taxa, sparsity, and heterogeneity. I will talk about some of the statistical methods in molecular microbial data analysis and demonstrate the methods using a plant microbiome dataset and R/Bioconductor packages. This talk is based on A Statistical Perspective on the Challenges in Molecular Microbial Biology published in Jeganathan and Holmes (2021). The workflow is available at https://pratheepaj.github.io/diffTop/.

Bio:
Dr. Pratheepa Jeganathan is an Assistant Professor in the Department of Mathematics and Statistics at McMaster University. Pratheepa's research focuses on addressing challenges in multi-domain data analysis. Her research team uses, extends, and develops statistical methods and computational tools to analyze microbiome multi-omic and spatial multi-omic data in R/Bioconductor, including topic analysis, hierarchical modeling, Bayesian statistics, multivariate statistics, bootstrap method, spatial statistics, and approximation theory in statistics. Currently, Pratheepa teaches undergraduate and graduate courses in statistics and data science.

Before joining McMaster University, Pratheepa completed postdoctoral training in the Department of Statistics at Stanford University.
She received a Ph.D. in Mathematics with an emphasis in Statistics and MS in Statistics from Texas Tech University. While completing her Ph.D., she interned at the Research and Testing Laboratory in Lubbock and the Clinical Research Institute at Texas Tech Health Sciences Center. She received a B.Sc.in Statistics and Operations Research from the University of Peradeniya in Sri Lanka. She taught undergraduate courses at Stanford University, Texas Tech University, and the University of Peradeniya in Sri Lanka.
