Her training crossed several countries. She earned her medical degree at Carol Davila University of Medicine and Pharmacy in Romania and an MSc in clinical immunology from London University, trained in the UK's NHS system, and holds MRCP and a Certificate of Completion of Specialty Training. She completed an internal medicine residency at Lincoln Medical and Mental Health Center in New York (2008–2011), a rheumatology fellowship through the Oxford Deanery in the UK, and post-doctoral lupus and rheumatology fellowships at Johns Hopkins (2012–2014) (https://www.hopkinsrheumatology.org/our-team/faculty/bio/homa-timlin/).
She sees patients at The Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center, where she is a site lead, and she is on the faculty of the Johns Hopkins Consultative Rheumatology Clinic (https://profiles.hopkinsmedicine.org/provider/homa-timlin/2708179). She publishes research on lupus, including papers on lupus nephritis after COVID-19 infection and after COVID-19 vaccination, and directs an IRB-approved study using MRI to help diagnose lupus nephritis (https://pure.johnshopkins.edu/en/persons/homa-timlin/).

Worth knowing
- Her Johns Hopkins division biography lists American Board of Internal Medicine certification in internal medicine. A separate board certification in rheumatology was not confirmed in the sources reviewed, so that part of her certification status is unverified here. hopkinsrheumatology.org
- A third-party directory (Luna) lists her specialty as "physical medicine," which does not match Johns Hopkins and other primary sources describing her as a rheumatologist. getluna.com

- No participation on national guideline committees, such as American College of Rheumatology guideline panels, was found in the sources reviewed. pure.johnshopkins.edu
- No personal or professional social media accounts (Instagram, X, Facebook, LinkedIn, TikTok, YouTube) were found, so there is little public commentary from her outside of Johns Hopkins pages and journal articles. profiles.hopkinsmedicine.org

A word of caution about these numbers
A payment does not mean your doctor is compromised or acting unethically. Most of these entries are drug samples left for patients, or lunch brought in for the office staff, and the amounts are usually small. Research funding and speaking at medical meetings are also normal parts of a clinical career.
As a rough guide, a total under $15,000 a year is usually not a concern. Much larger sums, especially from one company whose product your doctor recommends to you, are worth asking about. You are allowed to ask.
