I can't speak and write english well. But, here in an instrument lab, this X-windows permits only english. I'm operating a machine and it'll take more than 1 h. I got my Ph. D in a Korean college and now a post-doc in another univ. During my Ph. D course, I've got married, divorced and again married. So, for the last one and half year, I could not concentrate on my research. Owing to one or two good result during my early research and excuse of my advisory professor, I could acquire my Ph. D. But, as a result, my professor shouted me that doctoral degree would be surely the last one he could give me forever and he would not write a recommendation letter for me to any other professor. Cause he is very famous in his field and a senior to my present host professor, my present professor asked me no recommendation letters when I applied first. So, now I'm here - another Korean Univ. But, I want to go abroad to broaden my academic career. Now, I'm doing my best to get the confidential of my present host professor. I'm not sure- if I could apply for foreign country as a post-doc. I changed my main field - from basic science to applied science. to be far from the field and related professors of my former professor's.. But still, I'm not sure... Is there anyone who can advise me? Thanks in advance.
