Release Date:

Dr Marsha Tufft is a mechanical, aerospace, and materials engineer who has had a fascinating career with GE Aviation, and is now working on helping kids succeed in STEM through outreach and her middle school fiction books about a young girl named Putney and her STEM adventures.

Join us as we talk about Marsha's engineering journey, Putney's World, and underwater hockey.

About Dr Marsha Tufft

Dr. Marsha Tufft is an engineer, author, speaker, and problem-solver. Her passion is helping kids succeed in STEM fields – science, technology, engineering, math. She brings 35 years engineering experience at GE Aviation and degrees in mechanical, aerospace, and materials engineering to the creation of STEM experiments and projects that can be done at home because there’s nothing like learning by doing. She writes middle grade fiction books with a STEAM (=STEM+art) theme because stories change attitudes. Visit her website,, for STEM experiments, videos, and information about her books.
