 phene\, hexagonal boron nitride\, and transition metal dichalcogenides hav
 e recently received lots of attention due to their unique material propert
 ies and numerous potential applications. The 2D atomic structure can also 
 facilitate distinct defect formation mechanisms and offer new possibilitie
 s for defect engineering.  In my talk\, I will present the results from la
 yered molybdenum dichalcogenides (MoS2\, WSe2\, etc.)\, where vacancy\, su
 bstitutional\, interstitial\, and grain boundary defects are introduced by
  electron irradiation or by various chemical treatments. Due to the 2D nat
 ure\, the defect formation and properties can be characterized using trans
 mission electron microscopy and scanning tunneling microscopy. First-princ
 iples calculations are used to provide microscopic insight into the energe
 tics and kinetics of these processes. The gained understanding together wi
 th the computationally predicted defect properties can be used to guide fu
 ture efforts in tailoring the 2D material properties via defect engineerin
