The Devlin lab at Harvard Medical School uses strategies from chemical biology to study the human microbiome. Our goal is to control the chemistry of human-associated bacteria in order to understand how the microbiome affects human health and disease. The lab leverages expertise from different fields, including synthetic organic chemistry, molecular biology, microbiology, analytical chemistry, and bioinformatics. Learn about our research.

The Devlin lab would be a good fit for students and post-docs with either (1) an organic or analytical chemistry background interested in using chemistry to study biological problems or (2) a microbiology, biochemistry, or cell biology background interested in studying the human microbiome. If you are interested, get in touch.

Commitment to diversity, equity, and inclusion

In the Devlin lab, we strive to create an environment that values diversity, promotes an inclusive culture, and establishes a sense of belonging for each member of our group, both in lab and as part of the broader Harvard community. Collaboration, open communication, and trust are the cornerstones of our group. We welcome and support anyone regardless of race, disability, gender identification, sexual orientation, age, financial background, or religion.

Tweets from @DevlinLab

Save the date! Sloan Devlin (@DevlinLab) at @harvardmed is #ASBMBDeuel’s Journal of Clinical Investigation (@jclinicalinvest) Lecturer. Register for the conference to attend her talk, “Bacterial modification of bile acids alters host physiology,” on 3/ 8:

🚨New Episode!🚨

Join us with Dr. Devlin of Harvard Medical School ( @DevlinLab) as we talk about the gut microbiome research in her lab.

Gut bacterial modifications characterized so far involve hydrolytic & reductive pathways. @DevlinLab & colleagues have discovered a mechanism by which gut bacteria sulfonate steroidal metabolites that can modulate immune cell trafficking @NatureMicrobiol

We’re excited to share our latest paper in @ScienceAdvances led by Snehal in our lab and Darrik Li in Raymond Chung’s lab @MGHLiverCenter! Check it out!

Today’s #shoutout to #womenInSTEM goes to Lina Yao @DevlinLab for her @NatureMicrobiol paper on a biosynthetic pathway for selective sulfonation of steroidal metabolites by human #gut #bacteria.

OUT NOW👉Characterization of interactions of dietary cholesterol with the murine and human gut microbiome

By Elizabeth Johnson, Henry Le, Min-Ting Lee & colleagues @henrychembio @MinTingLee2 –
@lizljohnson @CornellCALS

In our final installment of Science on Tap 2022, @microbe_megan will be sharing her research on steroid metabolism in gut microbiota. Join us this Thursday at 4pm, Higgins 310!

We have lab members at #bostonbacterial2022 today! Megan @microbe_megan is presenting a poster today in session 3 and Wei @miniboe is presenting a poster tomorrow in session 4. We’re excited to be here!

ICYMI: Great study in @Nature from @DevlinLab and Jun Huh’s lab at @harvardmed identifying gut bacteria and enzymes that produce two anti-inflammatory bile acid metabolites, 3-oxoLCA and isoLCA. (1/3)

Bile acids have immunomodulatory properties. @DevlinLab & colleagues have found new clues into how human gut bacteria produce ΤΗ17-modulating bile acid metabolites with potential relevance for inflammatory disorders

It’s interesting to learn more about the underling mechanisms of liver damage prevention. @DevlinLab shows recent data on the role of unconjugated bile acids in inducing leaky gut while conjugated bile acids protect the gut barrier #GMFH2022
