Dapeng Zhang, Ph.D.

Associate Professor
Biology

Courses Taught

Bioinformatics I, Principles of Genetics, Biological Conflicts, Bioinformatics Colloquium

Education

Ph.D., University of Ottawa

Research Interests

We are interested in using Bioinformatics, Genomics, Evolutionary Theory, and Machine Learning techniques to address various biological and health-related questions, including:

  • Molecular mechanisms underlying biological conflicts, such as host-pathogen interactions, genetic conflicts, cell-cell interactions, and diseases in humans, animals, and plants. The focused systems include polymorphic toxin/effector systems, DNA modification systems, bacterial anti-phage effector systems, and eukaryotic immune systems.
  • Diversification mechanisms of biomolecules, including DNA, RNA, and proteins.
  • Antibiotic resistance and machine learning-based predictions.
  • Protein domain classification and function prediction.
  • Development of novel bioinformatics and machine learning methods, as well as specialized databases.
