Two complementary experimental programs have taken place to investigate the origin and evolution of shape coexistence in the light mercury region. Recoil Distance Doppler‐shift measurements were performed at the University of Jyväskylä utilizing the Köln plunger device in conjunction with the 
JUROGAM
+
RITU
+
GREAT
 setup. In addition, Coulomb excitation measurements of 
184,186,188
Hg
 were performed at REX‐ISOLDE using the MINIBALL Ge‐detector array. The results of the lifetime measurements of the yrast states up to 
𝐼
𝜋
 = 10
+
 in 
182
Hg
 are reported. Preliminary analysis of the Coulomb excitation data is also discussed.
