Can anyone recommended topic(s) I could use for my thesis under "Model Based Cluster Analysis"? I initially used "Inference in Model Based Cluster Analysis" as my working topic but appears to be broader than I expected. I want a topic I can relate with finding groups using model based cluster analysis. I would really appreciate your help.

A good option, in my opinion, would be to focus for example on high-dimensional model-based clustering. It is a very active field which is somehow linked to all the current "big data" hype.
The main idea behind is that, to cluster efficiently high-dimensional data, you either have to
assume that each group lives in a low-dimensional subspace (Tipping & Bishop, 1999)
project the whole data on a single low-dimensional subspace (Bouveyron & Brunet, 2012)
assume that only a few variables are truly relevant (Raftery & Dean, 2006)
A nice review is presented for instance by Bouveyron & Brunet-Saumard (2014). All these articles are freely available on their authors' webpages.
