Using my ethnically misleading name in a field where it's relevant
Would this be true for an American of Chinese descent who didn't speak Chinese as a native language? Or who might have been adopted and therefore has no childhood experience of Chinese culture?
You do have a personal connection: you married a Chinese man and you are a serious scholar of Asian studies. If it's really true that it's culturally offensive in a way that would be professionally damaging, then use your maiden name or whatever name you feel represents you as you wish to be represented. But this seems a bit overwrought to me. If you identify with Leung, then use Leung, and just deal with the fact that some people might have a problem with it. You're already OK with being a non-Asian Asian studies scholar--what do you say to anyone who objects to that?
I am a native speaking Chinese living in Taiwan. My field is in STEM, not Asian History. However, I have been reading quite a bit in Chinese history as a hobby since I retired in 2009. Still, I do not consider myself as a scholar in Asian History. Please take my answer as only amateur opinions.
You are right in that Chinese generally have a different perspective on Chinese history than someone who has no personal connection to the place. Actually, Chinese have different opinions on many issues in Chinese history among themselves. For example, there are different views on Qin Dynasty and its First Emperor.
If you pay attention to the reference and source sections of the Wiki page I provided above, you will see both Chinese names and Western names. Please note that I am saying Chinese/Western names, not Chinese/Western people because I don't know the people with Western names are actually Western or people with Chinese names are actually Chinese.
From this example, I hope you can see that the author name really does not matter. What matters most is the quality of the publication. As a personal opinion, I rather see a good quality paper written by a Westerner than a poor quality paper written by a Chinese on Chinese history.
I understand your concern that the readers of your publication may think you are a Chinese if you use your legal name. I think this might be true when they take the first glance at your publication. But, don't worry. They will soon find out it's written by a well Western-educated author. Your publication will tell them that. When I first read your question, I knew you have received well education in Western world because the way you wrote the question.
Now, I want to directly answer your question. I would use
Firstname White Leung
as the author name because this name accurately reflects your situation. "White" indicates you have Western connection. "Leung" indicates you have Chinese connection. It does not look weird to me at all. There is nothing wrong with telling people who you are.
In conclusion, I think your concern is reasonable given that your field is Asian history (If it's a STEM field, you have absolutely nothing to worry about.). Exactly because of this possible misunderstanding, you need to concentrate on your work to let your research speak for itself and not worry about the name you put on the publication.
A consideration would be to abbreviate your last name(s).
- Jane Smith becomes Jane S.
- Jane Leung becomes Jane L.
- Jane Smith-Leung becomes Jane S.L.
At the end of the day, perception is reality, given that you know the possible results, picking one or the other would have other effects, the decision (and its effects) are up to you.
