Kyeongjae Cho(名字太难念了,大家都亲切地叫他KJ),也就是版大在斯坦福的PhD老板,主要的研究方向为跨尺度模拟以及分子动力学、第一性原理在实际问题中的应用,现招收博士生和博士后。由于是版大的老板,大家可想而知,版上的各位的研究方向基本上都和KJ得很接近。

第一次认识KJ是在系里的Orientation(2001年),当时心里想,千万不要到这个说带着口音的英语的韩国人手下去,不然我的英语就废了。不过第一学期秋季上了他的atomistic simulation的课后,我就毫不犹豫的离开了原来已经呆了3个quarter的group,到了他的组里。因为我觉得原来的那个老板的知识的深度和广度和KJ不是一个量级的。其中一个特别让我钦佩的是KJ在课上和我们line by line的go through了一个叫做cgrad的程序(vasp得非常原始的前身)。个人觉得现在的环境下,一个教授能够即有很广的视野,又对于技术细节很清楚是很不容易的。现在想来,我还是为这个英明决定而自豪。我后来在KJ组里呆了4年,顺利的拿到了应用物理系的PhD,顺带一个电子工程系的PhD辅修学位。至于英语,我现在觉得对于一个Engineer来说其实完全不重要。

我自己在组里读PhD的时候,基本上用的主要软件有VASP,Gaussian,ChemSite,Tersoff-Brenner MD等。其中的分子动力学软件是自己组里开发的。当然了,光会用软件绝对称不上是一个出色的教授,最关键的是KJ的知识面非常的广,而且对于问题的把握非常的透彻和到位。可以说,没有KJ的点播,俺的那几篇PRL是绝对不可能的。每次和他讨论都让我感觉受益匪浅。

日常生活中,KJ也是非常Nice的老板。会有经常的Party,和大家措饭等活动。俺以前和他经常切磋网球和乒乓。可能是因为中韩文化比较相近的缘故,所以和KJ打交道比较的自在。KJ还略通中文,我父母参加毕业典礼时,他还用中文和我父母打招呼,问他们是不是“很高兴”。只要你能够顺利完成研究工作,KJ从来不会干涉其他的生活。所以我经常不去实验室(汗。。。我刚去的时候还是每天到实验室的),PhD期间修了很多无聊的课,比如网球、高尔夫、游泳等,KJ一概不管。一年里的vacation也要比其他的组多,所以在PhD期间,俺差不多游遍了美国,还回了两次国(两次签证都被check。。。)。

KJ本人和工业界有着很良好的关系,比如Intel, Texas Instrument (TI)等。在我读PhD的时候,就经常和Intel的人合作打交道。所以Intel的俺也去过N次,不过里面简直就像是迷宫,房间全部一模一样,一个个人则像hot electron一样乱蹦。KJ毕业的学生中,3个去了Intel,1个去了Cypress Secmidoncgtor, 一个去了NASA, 一个去了Sandia National Lab, 一个去了Univ of British Columbia当了教授,俺最不争气,去了KJ自己创办的公司(不过我倒是很喜欢这里的工作环境和我的工作性质,嘿嘿,没准一上市,拿准比去Intel强)。KJ和TI合作也很紧密,到了Dallas后估计和TI的合作会更上一层楼。KJ现在是Univ of Texas at Dallas的终身教授,准备招收2名博士后以及2名博士。俺会考虑优先推荐版上发言积极,俺自己觉得造诣比较高的(尤其是postdoc)。
