The RNAi in C elegans shows a lot of non-specific effec-and it can not be controled spatially, and there is no way to knock-out gene, transgene tech almost always express too much because of multiple copy, and it is also most of time unstable. mouse is very slow and quite risky. Recently, genome wide RNAi in fly is well established, you can K-down any gene in any fly tissue, recently two RNAi screen papers just published in Cell and there would be more. There are projects tagging every fly gene

all are good choice with potentials but u have to find ur own niche and bridge things together later on...People with mathematical mind, who also knows biology WELL will surely prevail in the future...the prime days for those who are very good with math but don't know much about biology are gone ...the opposite is less true but happening too...As well, it also depends on how ambitious you are... whether you just want to be trendy follower or want to be a pioneer...unless u are one of those and/o
sh*t, I thought you are dating a model and make her to orgasm.

NIH funded. what if NIH stops funding or completely dispears? Are you realy adding value and conrtributing to the improvement of people's lives? who in the world will be willing to pay you for your expertise? these are the questions you need to ask youself before you continue to put you best years in whatever you are doing. If these research have dubious value to society, such large scale funding/ spending will end, sooner or later.
(1) for any model organism, you can try homologous recombination to mutate anything you want. (2) for model organism like yeast, worm, fly, the best part of them is genetics. You can do "unbiased" genetic screen to identity anything change a defined phenotype.
