Data science has advanced to the point where it is changing our world. It is now the center of exploring and uncovering knowledge in different domains and acts as a bridge to connect them. With ever growing amount of data and opportunity to explore, the Data Mining and Information Systems (DMIS) lab aims to drive the data science revolution.
The main focus of DMIS Lab is to utilize and leverage AI and machine learning (ML) to solve problems in bioinformatics, drug discovery, and biomedical text mining. In order to diversify and strengthen its arsenal, DMIS Lab also conducts research in other areas such as natural language processing (NLP) and graph ML in order to uncover more-refined techniques to carry out its larger mission. Aside from conducting research, DMIS Lab also participates in various international challenges and competitions in order to contribute to the communal effort to tackle unmet needs in the field of biomedine, such as the DREAM Challenges and the BioASQ Challenges.
