Postdoctoral Research Fellow

Research Interests

My previous study in the astronomy field is related to the colrSome point-like QSOs with significant color variabilities are able to change their color classification according to our spectral definition. The timescales of the color variabilities for these point-like QSOs are within 4 years, suggesting that the size scales of the mechanisms producing the color variabilities are less than a few light years.

In the field of environmental research, I will compare the differences between model predictions and observed values ​​of air quality in western (central) Taiwan, and monitor the temporal and spatial changes of this difference.
