Why I am intrigued by the Beauty and Complexity of Language?

Language as Influence: Power and Memorability

Notes: It seems that Professor Lillian Lee is usually happy to work with very handsome students like Chenhao Tan and Christian Danescu Niculescu-Mizil. I feel upset about the fact I am not handsome enough to work with her....

First Meet with Professor Kathleen Mckeown

Having been heard of this lady several times, and last Monday at DAPG2015, I got to know her "physically" finally....

First know this professor:   

Summer 2013 when I traveled to NYC first time, I want to find out someone at Columbia sharing similar interest. Then I find her website...  But as usual, she did not reply to my email...

First time to see her physically: 

@KDD 2014, Bloomberg Headquarter, New York City..     I saw this lady talking with David Blei at the balcony outside 7th floor, Bloomberg.  But I am still too shy to say anything...

Mentioned by others:

@Counselytics, my intern advisor Jana told me Kathleen is advertising a competitor company of Counselytics, and said that it is very hard to take her time! Anyway Kathleen is the first tenured female CS professor at a distinguished Ivy League University called Columbia!
