Fields of Research

  • Biological Data Science

Researcher Summary

I work with my colleagues at the Biological Data Science lab and our collaborators to develop mathematics and computer science necessary to answer rigorous questions about molecular data. Our ultimate goal is achieved when we observe how molecular biology and data science shape modern mathematics and computer science.

Subject Area: Disciplines

  • Computer Science, Information Technology, Information Sciences: Algorithm Engineering; Theoretical Computer Science
  • Biology: Molecular, Cellular and Whole Organism Biology: Genomics/Bioinformatics
  • Mathematics: Applied Mathematics; Biomathematics; Computable Mathematics
