背景:楼主是**,低G低T,一般般的GPA,国内普通本科,非211非985,2013年本科毕业,至今失学失业. 今年申请了20所US院校的21个PhD programs, 考虑到自己的实力,主要申请的是综合排名50-100的学校,想法很简单,有funds资助我做有兴趣的项目就很满足,学校差一点地方偏一点都无怨言。截止目前的申请结果可以参考我的签名(还有8个结果没有出来)。

3月15日收到Clemson中国女AP的反套,问我有没有兴趣和她talk something through the phone,我是做ME微机械热流的,她是做ME纳米材料原子级力学性能的。我饥渴,她也饥渴,于是一拍即合。给了周日周一让我选一天,我想多准备一下,故选北京时间周一晚上9点。


面试中(女助理教授AP,我MQ. 涉及专业问答的部分,我用绿色字体标记出来,供有兴趣的同学、尤其是ME出身且有兴趣的同学参考。):.鏈枃鍘熷垱鑷1point3acres璁哄潧

AP: Hello, this is XXX from ME at Clemson.

MQ: Hello, Dr. XXX, this is MQ, how are you doing?

AP: Fine, thank you. I am interested in your paper, and I wanna ask you some questions. After that I think we could chat for a little.

MQ: OK. So what are your questions?

AP: The first question, could you introduce yourself briefly?
MQ: Oh, sure.

Then I started reciting the self-introduction I've prepared, including my family and major, my undergraduate researches, my current status, my hobbies as well as my qualities that a scholar should have.

AP: OK, are you doing the master in HZ XXX?

MQ: No, I just live there. HZ is the place my home is located in.

AP: OK. I know from your introduction that you have been doing some research work in Dr. D (my undergraduate supervisor)' s lap. Is that in HZ XXX?

MQ: No, it's in WH XXX (my undergraduate school).

AP: Can you introduce your paper. Is that a computational result or a experimental one? And what's your specific contribution in this paper?

MQ: OK, I am first author of this paper, I did the modelings, meshings, and simulations, etc. by my own. Then I wrote the paper by myself, of course Dr. D helped me refine the results and polish the writing. Yes, it's a totally computational paper, and we didn't do any experiments to verify the results.

And then I gave her a brief presentation concerned with the whole process of simulations and paper writing.

AP: Yeah, I see you set up three different materials and cross-section shapes. Did you think up such designs by yourself or Dr. D asked you to do that.

MQ: I set up those nine models by myself. I had refered to a number of references and found that those three types of materials were very suitable for MCC's manufacturing, and three types of cross-sections could well represent the normal channel shapes as well. Of course I have discussed many details with Dr. D at times.

AP: Bla bla bla.

I began to be confused about what she was saying.-google 1point3acres

. from:
MQ: Sorry, I didn't catch your point, can you say that again?

AP: OK, I am saying, bla bla bla.. 1point 3acres 璁哄潧

Still can't follow her. Because her speech was kind of slurred and fast and professional. Besides, I doubt I have a disbility in listening..鐣欏璁哄潧-涓浜-涓夊垎鍦

MQ: do you mean its boundary conditions?

AP: Yes and what are they?. Waral 鍗氬鏈夋洿澶氭枃绔,

MQ: the whole model can be devided into three parts. The first part on the top is an LED chip, it's actually the heat source for the whole model. And, um, um...

AP: Did you see temperature changed dramatically in your modelings?

MQ: Yes. After the cooling fluid going through the whole channel, the chip cooled down quickly, and the temperature accordingly dropped.

AP: Oh, you mean you have the fluid with high velocity to help it cool down? . Waral 鍗氬鏈夋洿澶氭枃绔,

MQ: Yes. Actually I just refered to the laws and derivative equations from Heat Tansfer, it's a text book. And I uploaded the derivative convective heat transfer coefficient to channel surfaces.

AP: And, what are other boundary conditions and your results?

Then I got stuck in such expression. I can't even read the units, the characteristic numbers and so forth. Really regret not to put effort into ME professional English in the senior year...Sigh...

AP: OK, you can speak Chinese.

I was really happy at that time, and I felt the heavy weight lifted off my heart!

如鱼得水啦!接着我很详尽地说了下我的建模,模型的边界条件,还有九个模型、四种不同测试的结果(其实一开始我自己用中文都已经说晕了),最后说了下结论和结论分析。. more info on

AP: In terms of materials, which one is the best?

MQ: Copper MCC has better cooling performance over other two materials. Of course if we consider their CMOS compatible microfabrication benefits, silicon would be a very promising material.

AP: 硅材料性能没有一点儿好吗?. From 1point 3acres bbs

MQ: 有啊,它从初始状态到达稳态所需要的时间最短。这个研究很有意思的一点就是,时间做出来效果排序是A1>B1>C1的话,温度做出来效果排序是A2>B2>C2的话,实际上综合效果并不是A1A2是最好的。

AP: 好的。你有什么问题吗?

MQ: could you please briefly introduce your research group, such as its current members, its facilities and research resources.. 涓浜-涓夊垎-鍦帮紝鐙鍙戝竷

AP: OK, bla bla bla.

. 鐣欏鐢宠璁哄潧-涓浜╀笁鍒嗗湴

暴快的语速,无法跟上。。。只记得关键词是 molecular dynamics, material behaviors.

AP: Can you follow me?

MQ: can't keep up with your pace.

AP: Fine.

MQ: 我曾经和一个HZ XXX材料学院的老师聊过,他跟我说纳米材料那些要用分子动理论来解决。. 涓浜-涓夊垎-鍦帮紝鐙鍙戝竷

AP: 我们也做过分子动理论,现在做的是比分子动理论还有微观的东西(好吸引人的感觉)。你听说过薛定谔方程吗?

. visit for more.
MQ: 听说过,但是我不是很清楚具体是怎样的。

AP: Never mind. 我们就是编程用薛定谔方程来求解。


. 鐗涗汉浜戦泦,涓浜╀笁鍒嗗湴
MQ: 这样啊。

AP: 其实你做的东西和我们做的有一定的相似处。

MQ: 我做的其实用的是宏观的理论,虽然叫微通道。

AP: 对。你们的材料都是普通的材料,我们的材料都不是这种常见的。你们设置的材料属性应该是泊松比啊、弹性模量啊这些普通的属性。

. 鐗涗汉浜戦泦,涓浜╀笁鍒嗗湴
MQ: 我们主要是设置的是材料的热物理性质,我没有考虑过材料的同向异性。就是用异向同性做的。

AP: 对呀(如同找到知己那种惊喜的语气)!宏观的材料根本无需考虑同向异性,异向同性足以解决问题。我不是做的热流,做的是材料方面的,不知道你有没有兴趣。

MQ: 有啊。

AP: 我这里打算给你个TA, 不过我要先去研究生院汇报下,他们可能会打电话来测试你的口语,都是日常生活用语,不会很学术。我认为你的英文发音非常标准,就是练习太少了,学术英语要加强。

MQ: 谢谢夸奖。

AP: 你还有什么问题吗?

MQ: 您有RA吗?我怕我口语不行。

AP: 我今年有一个TA和一个RA,TA是带本科生做力学实验的。RA的人我还在考虑,而且RA只有一年。你说的口语不行是什么意思?是觉得通过不了研究生院的测试吗?

MQ: 嗯。
. From 1point 3acres bbs
AP: 不要紧,我觉得你口语挺好的。而且,我会跟他们说的,我说你的口语可以,那就是可以!

-google 1point3acres
MQ: 好。

AP: Any questions?

MQ: 额。。。

AP: 哦,对了,你为什么读博?
. from:
MQ: speak in Chinese or English?

AP: 都可以。

MQ: 第一,从很小的时候开始,我就想在大学里面当老师。所以读博是必须的。第二,我非常喜欢科研,我在大学校园里面长大的,我不太会和社会上那些勾心斗角尔虞我诈的人打交道,我所想的就是能在一个单纯的环境中做我喜欢做的事情。第三,我的本科不是很好,我认为读博可以提升我的学历。

AP: 你的本科不是很好?

MQ: 嗯,高考没有考好。之前模考都过一本的分数线的,高考的时候第一次掉出一本分数线。

AP: 你觉得你本来可以读什么样的学校?
MQ: 只少是WH OOO校吧。您听说过WH OOO校吗?
AP: 没有。

MQ: 您听说过HZ XXX校吗?
. 鐗涗汉浜戦泦,涓浜╀笁鍒嗗湴
AP: 听说过。

MQ: 就是比HZ XXX差一点的学校。
. From 1point 3acres bbs
AP: 好我知道了。你现在有offe吗?

MQ: 没有。
AP: 我给你offer你会来吗?

MQ: Clemson是我目前申到的最好的学校,我会好好考虑和优先考虑,我想我应该会来的。

AP: 不给你offer你会来吗?

MQ: 不会。


AP: 是因为financial的原因吗?

MQ: 是的。

AP: 如果你今年没有offer,你打算干嘛?

MQ: 在中国读研究生。

AP: 你今年为什么没有就留在你的本科读研究生呢?. 鐣欏鐢宠璁哄潧-涓浜╀笁鍒嗗湴
. more info on
MQ: 第一我们学校没有资格保研,第二我要读研究生肯定回去一本读。

AP: 好的,我一周左右和你说研究生院口语的通知。

MQ: 嗯,我也觉得我平时说得太少了,都是突击托福口语考试才练习。我想我应该多多练习。

AP: 是啊,口语是非常重要的,你看你以后想做老师,口语不行怎么做呢?而且就算我们做科研,也不能低着头做科研,还要到处和别人打交道拉赞助,不然我们拿什么养活学生呢?你是不是一个内向的人?

MQ: 不是。我做科研的时候非常安静,但是我参加活动的时候还是很活泼的。
. 鍥磋鎴戜滑@1point 3 acres
AP: 好的。还要问题吗?

MQ: 暂时没有了。

AP: 好,今天就这样,两周以内我会给你最后的决定。

MQ: Thank you.

AP: Bye bye.

MQ: Bye, see you.

今天凌晨收到了两个教授的来信。一个是Alabama的男正教授,说正在帮我申请Fellowship, 问我要一些补充材料。这个教授是我之前套磁联系上的,他一共就和我写过6封信,都没有面试过我,第四封信就跟我说考虑给我RA, 不过会先帮我去申请Fellowship,开始以为他说说而已,后来觉得应该是真的。 另一个是昨天面试的女AP,问我会不会C++和matlab,以及我论文中的曲线图是什么软件做的。不会matlab有点担心会丢掉offer.


. 鐣欏鐢宠璁哄潧-涓浜╀笁鍒嗗湴
我爸妈昨天居然亢奋地失眠,可能觉得我辛苦这么久+gap一年终于有了positive的结果,我的bf一百年不玩QQ居然在QQ的签名上写关于我拿offer的事情。其实我还挺镇定的。我的本科导师Dr. D昨天到今天凌晨也很高兴,强烈要求我写点东西记录下这个时刻,说这是个值得铭记的时刻,若干年后看看自己写的东西会很欣慰。

是啊, pursuing the PhD degree abroad is a life-changing experience and one of the most rewarding things in one's life!
