ABOUT THE SPEAKER
Kaitlyn Sadtler - Regenerative tissue engineerKaitlyn Sadtler researches how our body can regenerate tissue through instructions from our immune system.
Why you should listen
Kaitlyn Sadtler is a postdoctoral fellow at MIT and received her Ph.D. from the Johns Hopkins University School of Medicine, where she discovered a certain type of immune cell -- the T cell -- was critical for muscle regeneration. This work was published in Science Magazine and has led to more findings in how our immune system responds to materials used in tissue engineering.
