In the Pollack Lab, we study interesting and relevant biophysical problems involving proteins, RNA, and DNA. With eight national research centers and laboratories focused on applied physics–four of which are supported by the National Science Foundation–our graduate students have access to some of the most advanced research equipment and technology in the world.

Developing and applying new methods to study the biological macromolecules: RNA, DNA and proteins

protein_2Our research strives to reveal the fundamental physics that drives biological processes. To achieve this goal we create and apply new tools to gain insight into outstanding biological problems.


Charge and biological molecules: why RNA folds and DNA condenses

charge_1Nucleic acids are among the most highly charged polymers found in nature, yet their biological roles require them to fold or condense into tightly packaged structures. We are studying the role of positively charged ions on these dramatic conformational changes.


Detecting Functional Motions of Proteins

motionsProteins carry out many important tasks related to life. We are interested in proteins as sensors of signals, such as light or ligands. We study how proteins transduce environmental signals into cellular information.
