Dr. Tsibris’s research currently focuses on the characterization of HIV-1 resistance to CCR5 antagonists, and the use of ultra-deep sequencing to demonstrate dynamic HIV-1 escape from CCR5 inhibition in vivo. In addition to his translational, bench-side research, Dr. Tsibris is committed to integrating novel lab findings of HIV drug resistance to improve patient care worldwide, while continuing to be involved in clinical care and teaching.
