Author Biography
Omid Motamedisedeh is a freelance data and business intelligence analyst with a PhD in Industrial Engineering. He's currently working towards his second PhD at Queensland University of Technology. Omid has authored six books in the field of Excel in Farsi, along with several articles in industry journals (Electric Power Systems Research, Journal of Building Engineering, Energy, Neural Computing and Applications, and more). His primary reason for writing his first book in English is the lack of a comprehensive and complete reference for Power Query functions. He decided to fill this gap by writing one himself.
