Laura J. Juszczak's Web site
After several years as a painting conservator, Laura Juszczak returned to New York University with the aim of becoming an art conservation scientist. On the way to a master's degree, however, her focus changed from the study of inorganic to organic pigments. She stayed on to complete a Ph.D.; her dissertation focused on the energy transfer mechanism in light-harvesting blue-green algae. Continuing with spectroscopy, she worked as a postdoc in the laser lab of Professor Joel M. Friedman, primarily studying hemoglobin mutants using the laser technique of UV resonance Raman(UVRR) spectroscopy. She stayed on at the Albert Einstein College of Medicine as a faculty associate. With her faculty appointment in 2006 at Brooklyn College, Juszczak earned NIH funding to apply UVRR and other spectroscopic techniques, together with molecular modeling simulations, to study the reporter molecule and amino acid, tryptophan, in proteins.
Education:
Postdoctoral studies, Albert Einstein College of Medicine - 1999 (Laser Spectroscopy of Proteins)
Ph.D., New York University - 1993 (Chemistry, Physical)
M.S., New York University - 1986 (Chemistry)
M.S., University of Delaware - 1979 (Art Conservation)
A.B., Wellesley College - 1976 (Art History)
Areas of Expertise:
Laura Juszczak's area of expertise is biophysical chemistry; her tools are spectroscopic, primarily UV resonance Raman. This technique is used to selectively probe aromatic residues in proteins, primarily tryptophan but also tyrosine. Such studies reveal details about protein conformation in both the normal and diseased state. This information allows us to understand the molecular level detail of the disease process, and helps researchers to design effective drugs.
