最近看了Dice帖子，讨论有机新生代的牛人，觉得挺有意思，但也有点意犹未尽。
现在响应他的号召，新开贴，系统地介绍有机化学的新生力量。
上个世纪90是年代独立工作的人，通过十几年左右的打拼，很多都已经功成名就，
成为人名教授了，像Greg Fu，MacMillan，List， Scott Miller， John Hartwig，
Amir Hoveyda，Erik Sorensen等等。现在有一批2000以后独立工作的人开始崭露头角
，渐渐被人们熟知，有机化学的江湖以后就是他们的天下，感觉现在有机到了更新换代
的时候了。
这个帖子的目的是系统地介绍2000（特别是2004年，如果是中国人则会放宽年限）
以后独立工作的有机领域的新生力量，旨在展现现在有机的前沿，年轻人的chemistry
代表着化学的未来。这些人有的刚刚拿到tenure，有的还为tenure苦苦打拼，从他们的
文章中，看到了努力，也看到了执着。从本帖开始，将以回复的形式，介绍当今有机化
学活跃的年轻人，希望从中能看到有机化学的未来。
为了保持帖子的完整性，Dice帖子里提到的人，... 阅读全帖 |

我是即将于2011年底毕业的环境工程Ph.D.。从去年开始陆续在一些学术会议中参加招
聘会，修改简历，了解工程界的市场形势和对员工的需求。最近注册了Mitbbs和一些专
业论坛，对找工作这个系统工程有了一个大致的了解，这里也要感谢众位前辈的经验。
今天是第一次发帖，算是给自己的找工作历程标记一个开始。找工作不同于申请或者作
研究，不是一个人单打独斗。所以希望在这里能和大家多交流经验，分享信息，同时也
是互相鼓励。下面附上我自己的的简历，希望大家能够不吝赐教，多提建议。另外我会
陆续把我的一些个人经验发上来。谢谢！
关于简历：我现在主要的目标是Consulting公司中的Scientist/Engineer。我在国内的
本科和硕士专业分别是给排水工程和市政工程，无论是工程还是研究经验都是偏重于水
和废水处理技术的应用，来美国后做的研究则偏向Science。客观评价的话，我的实际
操作能力较强，性格很开朗，善于交流，喜欢学习新知识，所以感觉Consulting应该是
个不错的尝试，而一份目的明确的简历则是这个尝试的开始。考虑到这个目标，我的简
历是否过于偏重自己的研究经验了呢？G... 阅读全帖 |
