Voelker Laboratory

Laboratory PI Information

Dennis R Voelker, PhD

Dennis Voelker performed undergraduate work at Indiana University and completed graduate studies in Biochemistry/Biomedical Sciences with Fred Snyder, at Oak Ridge National Laboratory/University of Tennessee, in 1979.  He conducted postdoctoral studies with Eugene Kennedy at Harvard Medical School.  In 1981 he joined the faculty of Medicine at National Jewish Hospital, with a joint appointment in Biochemistry Biophysics and Genetics at the University of Colorado School of Medicine.  He is currently Professor of Biochemistry and Molecular Genetics and Medicine at National Jewish Health with a joint appointment at the University of Colorado School of Medicine.

 

Research Focus of Voelker Laboratory

The Voelker laboratory conducts basic research examining the cell and molecular biology of lipids related to the problems of membrane and organelle biogenesis in eukaryotic cells.  Additional areas of investigation include both the lipid and protein elements of pulmonary surfactant, and concentrate on mechanisms of suppressing inflammation and bacterial and viral infection.  The long-term medical applications of this work are to uncover new approaches for regulating cell growth and development; and to develop new pharmacological interventions for preventing bacterial and viral infections and the destructive inflammatory processes these infections cause in the lung.

 

Lab Resources and Services

The Voelker laboratory utilizes the tools of contemporary cell biology, molecular biology, biochemistry and genetics to address problems of intracellular phospholipid transport and membrane biogenesis, and the structure and function of pulmonary surfactant lipids and proteins. Learn more.
