Back on X after a break — excited to reconnect. I’m a UCSF gastroenterologist and inflammatory bowel disease specialist focusing on anal cancer prevention, and LGBTQ+ health equity. Expect research highlights, clinical perspectives, and advocacy.

Honored and grateful to receive this award. Excited to help advance cancer prevention efforts for people living with IBD. Thank you @AmCollegeGastro and to my incredible mentors for your guidance, support and belief in this work @UmaMahadevanIBD @ucsfibd
