Research

Research Topics, Overview of the research

• Research Topics

  -Molecular ecology of sea turtles
  -Functional morphology and locomotion of turtles
  -Biologging and biotelemetry of aquatic animals

• Overview of the research

  I am trying to understand ecology, behavior, and function of animals through quantifying and visualizing various information of them. Study animals are aquatic animals, mainly sea turtles.
