Paurush Praveen Sinha has been working with R for the past seven years. An engineer by training, he got into the world of bioinformatics and R when he started working as a research assistant at the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI), Germany. Later, during his doctorate, he developed and applied various machine learning approaches with the extensive use of R to analyze and infer from biological data. Besides R, he has experience in various other programming languages, which include Java, C, and MATLAB. During his experience with R, he contributed to several existing R packages and is working on the release of some new packages that focus on machine learning and bioinformatics. In late 2013, he joined the Microsoft Research-University of Trento COSBI in Italy as a researcher. He uses R as the backend engine for developing various utilities and machine learning methods to address problems in bioinformatics.
