The Berger Lab's research is focused on understanding how multi-subunit assemblies use ATP for overcoming topological challenges within the chromosome and controlling the flow of genetic information. A long-term goal is to develop mechanistic models that explain in atomic level detail how macromolecular machines transduce chemical energy into force and motion, and to determine how cells exploit and control these complexes and their activities for initiating DNA replication, shaping chromosome superstructure and executing myriad other essential nucleic-acid transactions. Our principal approaches include a blend of structural (X-ray crystallography, single-particle EM, SAXS) and solution biochemical methods to define the architecture, function, evolution and regulation of biological complexes. We also have extensive interests in mechanistic enzymology and the study of small-molecule inhibitors of therapeutic potential, the development of chemical approaches to trapping weak protein/protein and protein/nucleic acid interactions, and in using microfluidics and single-molecule approaches for biochemical investigations of protein dynamics.

URobotics is a research and education program that uses advanced technology to improve how urological diseases are diagnosed and treated. The URobotics lab’s main focus is creating robots that aid in real-time, image-guided interventions. This multidisciplinary team of urologists, radiologists and engineers has teamed up to revolutionize how surgeries are performed.

The Linda Smith-Resar Lab primarily investigates hematologic malignancy and molecular mechanisms that lead to cancer as well as sickle cell anemia. Recent studies suggest that education is an important and effective component of a patient blood management program and that computerized provider order entry algorithms may serve to maintain compliance with evidence-based transfusion guidelines. Another recent study indicated that colonic epithelial cells undergo metabolic reprogramming during their evolution to colorectal cancer, and the distinct metabolites could serve as diagnostic tools or potential targets in therapy or primary prevention.
