NCI Postbaccalaureate fellow Alana Thomas was thrilled to attend the HIV DRP Think Tank for her second time. Professor John Coffin, Ph.D., was attending for his 27th time—and was no less thrilled. Looking on, it was easy to see why. The 27th HIV Dynamics and Replication Program (DRP) Think Tank, hosted by NCI Frederick, was a decidedly intimate gathering as far as scientific meetings go. The 18 short lectures and small guest list played a part in that—just over 130 scientists attended this year, most of them federal or National Laboratory employees—but more pervasive was the current of passion and tight-knit camaraderie.
