**Research
Interests:**

Since 1990, Dr. Bak has collaborated
with Dr. Charles S. Brown to develop the unified polarization calculus, which
is a Lorentz-group based formalism that exploits the analogy between the
Mueller matrices of polarization optics and the Lorentz transformations of
special relativity. This calculus
incorporates the traditional approaches (namely, the Jones, coherency, and
Mueller calculi) into a single unified formalism. Some of the fruits of the unified polarization calculus have
been: [1] the general Mueller matrix for arbitrarily coupled birefringence and
dichroism in a closed analytical form, [2] an inversion algorithm that yields
the birefringence and dichroism responsible for a given Mueller matrix, [3]
important limiting conditions on Mueller matrices, and [4] a closed analytical
expression for stochastic Mueller matrices involving coupled birefringence and
dichroism.
