Title: "Higgs Models with Multiple Doublets" 

Abstract: Multi Higgs-doublet models (NHDMs) are amongst 
the simplest extensions of the Standard Model, motivated 
for instance by Supersymmetric scenarios. I will discuss 
NHDMs with various symmetry groups which contain viable 
dark matter candidates, preserved by the remnant of the 
symmetry after EWSB. I will describe the dark matter 
phenomenology of these models and look into new Higgs 
decay channels offered by the extra doublets and their 
effect on the Standard Model Higgs couplings.
