Post-doctoral positions at KAIST
If you are interested in becoming a post-doctoral researcher working with me, then please contact me. You can also send me 1) your cover letter, 2) CV, 3) research statement, and 4) arrange at least 2 letters of recommendations sent to my email. (By regulation, you should have your Ph.D. degree ready on the first day of your work.— The Ph.D. defense is not enough.)
