About Us

William Wu

Dr. William Wu received the B.S. degree in Electrical Engineering and Computer Science from UC Berkeley in 2003. At Stanford University, he received M.S. degrees in Electrical Engineering and Mathematics in 2005 and 2009, and the Ph.D. in Electrical Engineering in 2010, under the supervision of Professor Brad Osgood. In 2002, he created, a popular archive of mathematical puzzles with an active forum of +10,000 registered members. His research interests include signal processing, natural language processing, cryptography, and recreational math. Dr. Wu is a former member of the NASA Jet Propulsion Laboratory, where he served as a telecommunications researcher and engineer, and developed signal processing software for various missions including OPALS, MRO, GRAIL, and Curiosity.

Dr. Wu has served as an independent technical consultant for numerous industrial clients, working on projects ranging from scientific computing for bioinformatics and geospatial applications to building enterprise software for streamlining workflows in research labs. Dr. Wu also has had over 10 years of experience in award-winning tutoring.

Jiehua Chen

A native of China's Zhejiang province, Dr. Jiehua Chen ("J.C.") received her B.Sc. degree in Mathematics and Physics from Tsinghua University, summa cum laude. In 2008, she received the M.S. in Economics and the Ph.D. in Statistics at Stanford University, under the supervision of Professor Paul Switzer. She has served as a Postdoctoral Fellow and Assistant Professor in the Statistics Department of Columbia University, and has served as a senior statistician for the United Nations Development Programme, as well as a consulting statistician for the Earth Institute at Columbia and the African Soil Information Service in Tanzania, funded by the Gates Foundation.

JC has devoted her statistics expertise to socially and environmentally conscious research projects, most of which are related to improving life in developing countries. These projects include mitigating risk factors for sexual workers in Mongolia, distribution and impact evaluation of fuel-efficient stoves in Uganda, fair pricing of index insurance for crop farmers in Ethiopia, designing sampling algorithms for soil quality monitoring in Tanzania, statistical analyses of Jatropha adoption in Mali, and econometric modeling of the rapid urbanization of China. She has extensive international field experience, often living in Africa for many months at a time. Her interests also include applications of statistics to public policy and bioinformatics.
