Tom Squier

Dr. Squier's research centers on the development and application of molecular probes to visualize protein structrural dynamics in native biological environments using fluorescence spectroscopy. Newly developed probes permit the detection of structural heterogeneity and functional readouts of proteins tagged with small binding sequences in living cells. These measurements are important in understanding the basis for molecular recognition and catalysis, and offer a means to collect the necessary functional data in response to environmental change for the construction of predictive cellular models.Dr. Squier has held a variety of academic appointments and currently serves at Washington State University as an adjunct professor of biology.
