The laboratory is in the Bethesda campus and adjacent to the animal facility that houses all of our mice. Lab members include a senior researcher beside P.I, and about 6 post-doctoral fellows. Additionally, a Post-Bac student and summer interns are present in some years. We aim for maintaining a friendly, open atmosphere conducive to free interactions, and cooperation and initiative taking are encouraged. To ensure good communication, the P.I meets each fellow on a weekly basis to discuss research progress and future directions. We attend the weekly lab meeting and PGD group meeting regularly. We are also encouraged to attend ad present in various seminars and symposia in the NIH and nationwide.
