My two cents:
1. Your publications make you competitive enough for for a faculty position.
2. You don't have a record of funding. That is a weak point.
3. At least from your description, I don't see a strong sign of you being
independent. You have to be able to demonstrate that you have a vision in
term of what you want to do for your own lab, which can potentially lead to
funding.
4. C. elegans is quiet out of favor these days as far as funding goes. It
can be hard for newcomers.

draft sequence is easier and cheaper to get than the finished sequence, it
has lower sequence coverage and contains lots of unclosed gaps.
Basically, if you already get a organism's finished sequences, to sequence its
related species might only need to be draft oriented. For example,
C.elegans vs. C.briggsae. Thus, draft sequences is widely used in comparative
genomics.

做植物的最早发现了一种叫做corepression的现象,这种现象按我的理解是,就是用转
基因的方法去rescue一个phenotype,结果却产生了一种loss of function的phenotype.
当时植物学家无法解释这个现象,而且做corepression还要generate transgenic
lines,其实挺不方便的。后来做其他organisms也发现了这个现象,但都不知道机理。
好,现在让我们跳到1995年.康乃尔大学ken kemphues实验室研究的一个非常聪明的中
国学生,Guo Su(现在UCSF), 发表了一片cell的文章。在这篇文章中,她做了一个
antisense phenotype copy analysis,就是in vitro transcribed antisense RNA of
par-1,然后直接注射到c.elegans gonad,希望能够knockdown par-1 activity.事实上

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

其实我的兴趣比较在于:genome research,或者epigenetics,但比较偏向用
microarray+large data analysis这样的研究。。就是很纯的科学研究吧。
一方面是对这些东西比较有兴趣(我觉得genome的研究还是很有前途吧?因为现在对
genome的认识还非常少)另外一方面,是比较希望有quantitative science方面的训练
,以后也是希望可以做多学科交叉的那样的方向吧。
而这样的research,(用quantitative手段的),肯定要放在比较简单的systems里面
做吧?比如yeast,最多C elegans,有放到老鼠里去做的吗?(个人愚见,拍砖)因为
感觉这种genome的研究本身就是和model关系不大的吧。
然后一定要偏向医学研究,都做到老鼠水平才能在industry有个退路吗?比如我做
genome,对那些sequencing的东西比较内行,是不是也可以在industry找到工作呢?
