Research Group News:
  • June 2017, a proposal led by Prof. Huang and submitted to U-M and SJTU joint research program on data science has been selected for funding. This proposal aims to use machine-learning algorithms to improve the focast of solar irradiance and then electricity generated by PV (photovoltaic) panels. A new research direction for the group!
  • May 2017, Zach Fair was awarded the highly competitive NASA Earth and Space Science Fellowship.
  • May 2017, Fang Pan successfully defended her Ph.D. and, on the day before the defense, she was awarded the highly selective NASA Postdoctoral Program (NPP) fellowshp. Double congratulations, Dr. Pan!
  • April 2017, Colten Peterson will join our group in this incoming Fall semester. He has been awarded the MICDE graudate fellowship and the Dean's fellowship for his outstanding academic standing. Welcome Colten!
