I am an astronomer focusing on observational projects and have been observing with the largest telescopes over the world. One of the most exciting things to me is observing on the top of a mountain and pointing the telescope at a target which is quite far away from us in space-time. I am interested in observations from optical and near-infrared to submillimeter wavelength. I have over 30 nights observing experience on 8-10 meter class optical/near-infrared telescopes, over 80 nights of observing experience on 5-6.5 meter class telescopes, and over 60 nights of observing experience on 2 meter class telescopes. In addition, I also experienced with submillimeter observations with JCMT.
