George Blagdon

Engineering Director, WTTC

George is the Engineering Director at the Wind Technology Testing Center and has been active in wind turbine blade testing for over 12 years. Over this time, he has led the transition to testing ultra-long blades and will play a key role in the future plans of the facility. George leads a team of test engineers and takes a hands-on approach to engineering, never passing on an opportunity to climb in a blade. He acts as an expert technical assessor within the IECRE accreditation scheme, spending time in test facilities worldwide, and participates on the maintenance team for the IEC 61400-23 specification. Passionate about early STEM education, he has played a role in hosting hundreds of high school students for tours at the facility.


He holds a BS in Mechanical Engineering from UMass Dartmouth and an M.B.A from UMass Boston. Outside of work, you can find him spending time with family, working on the house, or getting lost in mountain biking trails.
