How to not fall in love with my co-author? I am a post-doc (male) and I am working on a research project with another post-doc (female) from the same university. During our work, I got to know her and started developing emotions towards her. Recently, I find myself thinking about her and missing her between our weekly meetings, instead of concentrating in my research. I do my best to avoid this development, in particular:


No physical contact, even not friendly handshakes.
No social events, even not eating lunch together. We only meet once a week to talk about our research.
No romantic talks, I never tell her that I like her or miss her or anything else that can be interpreted romantically.


But this does not help very much. 

I worked with other women in the past but this is the first time I feel this way.

I am NOT interested in any romantic relationship now. I only want my focus back. How do I get it?

EDIT: After reading the answers, I did some research and found some relevant articles.


"She Wanted to Do Her Research. He Wanted to Talk 'Feelings.'" claims that women might be disturbed by expressions of romantic feelings by men colleagues, to the point that some of them decide to leave academia altogether. Of course, there is difference between senior-junior relations and two postdocs of the same level (as is my case), but this is still quite disturbing. And it makes me feel happy I did not reveal my emotions.
"Sexist Scientist: I Was Being 'Honest'" is about a man professor who was bashed and fired for saying "let me tell you about my trouble with girls... Three things happen when they are in the lab: You fall in love with them, they fall in love with you, and when you criticize them, they cry". This further illustrates the problem with talking about love in academia.


And, I think this might show that the question is on-topic in academia.
I'm afraid I can't answer your question about how to suppress romantic feelings you have for another person, for the trivial reason that humans have been grappling unsuccessfully with this question for thousands of years. The attempts to answer it have led to some wonderful works of fiction though, so I recommend that you do a "literature search" on the problem (pun intended) and maybe find some of the answers you seek.

What I can also add is that one of the most romantic love stories I'm aware of in science started off in a situation pretty similar to yours. It involved the meeting and eventual marriage of the mathematicians George Szekeres and Esther Klein. They were married for around 70 years and died of natural causes on the same day - see here, here and here for more details. So maybe falling in love with a coauthor is not something that one should categorically rule out. Of course, only you know your own circumstances and can decide whether this lesson is applicable to your situation.
