The surfaces that line our airways and gut constantly meet the outside world, so they are often infected or damaged. Healing them requires both calming inflammation and rebuilding the cell layer, the epithelium, that forms the barrier.

What they work on

  1. Determine how macrophages, tissue-patrolling immune cells, regulate inflammatory responses after viral or chemical damage to mucosal tissues in ways that promote host survival.
  2. Define how macrophages communicate with epithelial cells to drive repair of damaged barrier tissue, using in vivo damage models.
  3. Use ex vivo organoid systems, small lab-grown tissues, to identify new regulators of macrophage-epithelial interactions during tissue repair and remodeling.

More about the research

Local stem cells are known to rebuild this layer, but how nearby immune cells help is less clear. This project focuses on macrophages, immune cells that patrol tissues, clear debris and help keep tissues stable. Their direct role in regrowing damaged epithelium is not well understood.

Why it matters

Damage from infection or injury to barrier tissues and the inflammation that follows feature in many complex diseases. Learning how macrophages promote repair could help develop treatments that dampen harmful inflammation, speed healing after infection and injury, and reduce the scarring-like tissue remodeling seen in many disease states.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
