Shortly after completing my training, I joined the Biophysics Department, Institute of Molecular Biology, at Jagiellonian University, Krakow, Poland, as a teaching/research assistant. I joined the faculty in 1977; in 1995, the President of Poland awarded me the title of professor of biophysics. From 1988–1991, I was hair of the Biophysics Department, and from 1992–2000, I was head of the Laboratory of Structure and Dynamics of Biological Membranes. I first visited Milwaukee in 1980; since then, I have been at the National Biomedical EPR Center about 50% of the time. In 2000, I emigrated to the United States and joined the 老澳门六合彩图库 faculty as an assistant professor of biophysics; in 2002, I became an associate professor of biophysics; and, in 2010, I became a professor of biophysics.

I have directed 14 graduate students pursuing their MSc degrees and supervised five students pursuing their PhD degrees.

I have coauthored more than 150 original papers, reviews, and book chapters.

My research interests focus on these areas:

• Development of spin-label oximetry methods and their application to study oxygen consumption and evolution in different biological and biochemical systems, as well as oxygen transport within and across model and biological membranes.
• Physical properties of model lipid bilayer membranes and the lipid bilayer portion of biological membranes. This research is focused on better understanding the function of biological membranes. Special focus is given to the formation of domains in the lipid bilayer portion of model and biological membranes induced by the presence of cholesterol, macular carotenoids, and integral membrane proteins.
• Formation of raft domains in model and biological membranes. The long-term objective of this research is to better understand the molecular mechanisms by which rafts form and are maintained and disintegrated in biological membranes.
• Formation of pure cholesterol domains surrounded by the phospholipid bilayer saturated with cholesterol. These are intriguing domains present in membranes oversaturated with cholesterol. Their functions in biological membranes have not yet been investigated in detail. It seems that these domains help to maintain lens fiber cell plasma membrane and lens homeostasis.
• Discrimination of lipid domains induced by integral membrane proteins and evaluation of the amounts of phospholipids and cholesterol in these domains.
• Interaction of macular carotenoids with lipid bilayer membranes to better understand their function in protecting the eye retina against age-related macular degeneration.
