Description of Research Expertise

The central theme of my current research is the study of large macromolecular assemblies that regulate genetic information. My investigations have included:

1. Viral proteins that mediate lateral DNA transfer, including retroviral integrases and phage-encoded site-specific recombinases.
2. Large macromolecular assemblies that regulate RNA, including the Survival of Motor Neuron (SMN) complex, bacterial group II introns, and ribosomes.
3. The nucleosome, which is the basic repeating unit of chromatin.
4. Intrinsically disordered proteins, including LEDGF/p75, SMN, and PGC1.

I routinely employ a gamut of biochemical and biophysical techniques to approach specific problems in these systems related to structure and function, with a particular expertise in and emphasis on biophysical approaches. This includes small-angle scattering, size-exclusion chromatography in-line with multi-angle light scattering (SEC-MALS), analytical ultracentrifugation and atomistic modeling methods.
