Data Structures and Algorithms

Great efficiency in data processing and analysis requires a good understanding of data structures and algorithms. Good performance in applications of bioinformatics demands a good understanding of how to efficiently organize and manipulate data. Typical data structures such as arrays, linked lists, and hash tables should be well understood. The basis is provided by algorithms for sorting, searching and sequence alignment.

Database Management

Given that in bioinformatics, one needs to deal with very vast amounts of data, knowledge of database management becomes essential. Knowledge of SQL and experience in relational databases, like MySQL or PostgreSQL, shall help one deal with and come up with queries of biological data. In addition, you should also have knowledge of NosQL databases such as MongoDB bearing in mind the state of data in an unstructured state as regards genomic sequences and their experimental results.

3. Data Analysis and Statistical Skills

Statistical Methods

Bioinformatics methodologies are all but completely reliant on the use of statistical techniques to gather and analyze data. Probability, testing hypotheses, and regression analysis are just a few of the concepts that comprise an integral part of the discipline. These are used for making biological inferences from data, determining the significance of results, and validating them. Expertise in the relevant statistical packages, especially Bioconductor in R, shall further add to analytical capabilities.

Machine Learning and Data Mining

Machine learning, and data mining techniques in bioinformatics, are increasingly important. These allow one to mine significant patterns or make predictions from complex biological data. It would be useful to learn algorithms such as clustering, classification, and neural networks. For example, machine learning can be applied in the prediction of protein structures, identification of disease genes, and cancer classification into subtypes based on their gene expression profiles.
