From a senior postdoc point of view, it seems hard to raise funding or get tenure track position working on old research topics in which his/her mentor made career long ago. As such, I am wondering in which research areas should a postdoc focus from career development point of view. The following areas seems to be hot now a days:
Algorithm/web server development and data analysis for -
- Epigenomics (BS-Seq, CHIP-Seq etc)
- Metagenomics
- Genome Editing
- Non-coding RNAs
- Applications of Machine Learning (i.e. Deep Learning) in these areas
- Genomic Big Data Management
Personally, I think the metagenomics is potential in many fields and I recommend the metagenomic sequencing in the study of microbial function in human health.
The metagenomics area in interesting indeed. And there's also the holy grail of protein structure prediction, a field that hasn't progressed much since the 1990s, with the development of SWISS-MODEL and related programs (although I'd say that the problem's being confronted since the 1970s, when Chou and Fasman formulated their famous amino acid helix/beta sheet propensity tables).
I would include high throughput in-vivo imaging to the list.
