Ai Ing Lim studies how the immune systems of mothers and their children interact during reproduction and early life development. From pregnancy to lactation, a mother’s immune system undergoes dramatic changes to support the developing baby while maintaining her own health. Lim’s lab investigates how these immune shifts affect not just reproductive organs but also the broader physiology of the mother during and after reproduction. Lim also explores how maternal exposure to widespread environmental factors shapes the offspring’s immune development. By studying maternal-offspring immune partnership, Lim aims to improve women’s reproductive health and optimize immune trajectories for future generations.
