My research group exploits the benefits of the stratospheric balloon environment by developing and flying balloon-borne telescopes which operate at a variety of wavelengths to achieve a range of high-priority science goals. Atmospheric attenuation and noise in the substantially degrades ground based observations of sub-mm wavelength light, even from the tallest mountains, and refraction by the turbulent atmosphere limits the resolution of visible light observations from the ground. Astronomical telescopes flying from stratospheric balloons at 35km to 40km altitudes avoid these negative effects, providing an economical alternative to space-borne missions. In the next period my group will work on Spider, BLAST, and BIT.

我的研究小组通过开发和飞行气球携带的望远镜来利用平流层气球环境的好处，这些望远镜在不同的波长下运行，以实现一系列优先科学目标。大气中的衰减和噪声大大降低了对亚毫米波长光的地面观测，即使是来自最高的山脉，湍流大气的折射限制了来自地面的可见光观测的分辨率。从35公里到40公里高度的平流层气球飞行的天文望远镜避免了这些负面影响，为太空任务提供了一种经济的替代方案。在下一阶段，我的团队将致力于蜘蛛、爆炸和比特。
