M.S., Ph.D., Indiana University
Professor Colladay received his Ph.D. in theoretical high energy in 1998. He has done research on the question of modifications to the equations of basic physics due to as yet undiscovered effects at very small length scales. Professor Colladay is a specialist primarily in quantum mechanics. In addition to teaching a number of courses in the traditional physics curriculum, Professor Colladay offers a course directed at the general student on the subject of basic high energy physics and its connection to modern cosmology.
Ph.D., Duke University
Professor Ruppeiner’s research has focused on using curved space geometry to represent physical situations in which many atoms cooperate to produce a few independent average properties, i.e., thermodynamics. Although the laws of thermodynamics make no reference to atoms, thermodynamics nevertheless yields information about microscopic properties. The curved space geometry is very revealing in this connection.
As an example, Professor Ruppeiner has applied these ideas to black holes, where the thermodynamics is well-known (due to Stephen Hawking and others), but the properties of the “atoms” is unknown. Professor Ruppeiner has also published in the areas of the large-scale arrangement of galaxies, computer approaches to "intractable" problems, theory of fluids, and using electric currents to probe the Earth.
M.Sc., PhD., Sofia University
Professor Sendova received her Ph.D. in experimental solid state and laser physics in 1989. She has done research in the areas of pulsed laser-plasma deposition of thin films and laser-assisted surface modification, as well as studied the structure, electrical and optical properties of novel narrow gap semiconductor materials. She has several publications in the area of biophysics and magnetochemistry as well.
In addition to teaching a number of courses in the traditional physics curriculum, Professor Sendova offers a course directed at life sciences' students interested in applying principles of physics to biological systems. Her current research projects are related to laser-assisted modification of metal nano-particles in dielectric thin films, micro-Raman spectroscopy of carbon nanotubes and applications of physical methods for analyzing objects of art.
