Our Team

Wisdom Tech was founded in 2017 by a team of medical physicists with strong reputation in R&D, software engineering, and clinical radiotherapy who are recognized by numerous professional awards including:

National Science Foundation / Faculty Early Career Development (CAREER) Award (1999)

Randal S. Caswell Award for Distinguished Achievements by CIRMS (2015)

Distinguished Scientific Achievement Award by Health Physics Society (2018)

Edith H. Quimby Lifetime Achievement in Medical Physics by AAPM (2020)

Arthur Holly Compton Award in Nuclear Science and Technology Education) by ANS (2020)

Rockwell Lifetime Achievement Award in Radiation Protection and Shielding by ANS (2020)

Award of Merit in Medical Physics by International Union of Physical and Engineering Sciences in Medicine (IUPESM) (2022)

Headquartered in China (Hefei, Anhui Province) with North America sales and tech support office in USA (Los Angeles, CA), Wisdom Tech is a spin-off from the internationally renowned University of Science and Technology of China (USTC) which continues to provide R&D innovation and talented employees. The management team contains individuals with extensive entrepreneurial and managerial experiences.

The idea leading to ArcherQA® technologies originated from a research project started in 2009 at Rensselaer Polytechnic Institute (Troy, New York) — the oldest engineering school in North America. The research was funded by a large number of highly competitive NSF and NIH grants (including several R01 and fast-track STTR/SBIR grants). The research and commercialization of the ArcherQA technologies took off at USTC (Hefei, Anhui).
