Research Interests

Prof. Johnson is internationally known for his work on ocular biomechanics, particular with regards to the pathogenesis of glaucoma and age-related macular degeneration. Studies in his group currently involve a bioengineering approach that utilize perfusion studies, atomic force microscopy and theoretical analysis in combination with use of high-resolution morphometry and finite element modeling. He has been involved in the study of a variety of physiological transport and mechanics problems for the past 30 years including flow through the aqueous humor outflow pathways as relates to glaucoma, transport and mechanics of the arterial wall, transport through the cornea, transport through macromolecular gels such as hyaluronic acid and Matrigel, transport through Bruch’s membrane and cell mechanics.

Courses Taught

  • BME 377: Intermediate Fluid Mechanics. Fundamental concepts of fluid dynamics. Kinematics, mass and momentum balances, constitutive relations. Navier-Stokes equations and methods of solution. Scaling techniques.
  • BME 378/478: Transport Fundamentals. Fundamental and biomedical applications of diffusive and convective heat and mass transfer.
  • BME 452: Transport Through Connective Tissues. Fluid flow and mass transfer applications through extracellular matrix. Porous media theory. Applications to drug transport.

Selected Publications

In the Classroom

Professor Johnson's teaching philosophy centers on the importance of problem solving. All of his courses focus on this engineering skill. In collaboration with Professor Ross Ethier of Georgia Tech, he is publishing a book (through Cambridge University Press) on flow and transport problems that emphasizes these skills.
