Doug studied chemistry but also studied biology, physics, mathematics, and astronomy earning his BS in Chemistry from Central Michigan University. He researched computational chemistry and XPS at Notre Dame. He was a TA in both Chemistry and ASL labs.Doug continued his education in chemistry working toward a Ph.D. in Chemistry (Physical Inorganic) and an M.Ed. in Adult Education from Colorado State University. He also worked for Pacific Northwest National Labs in Washington state doing computational chemistry research for potential battery and BNCT cancer treatment applications. He taught throughout his graduate study and then as adjunct faculty at Front Range Community College and Colorado State University. He ran the upper division undergrad lab program at CSU and supported the program writing grants and obtaining support from local corporations.In his time at The Princeton Review (TPR), Doug taught ACT, SAT, GRE, GMAT, OAT, DAT, MCAT, AP and SAT Science and Math Subject Tests and was involved in the development of a life skills program known as Up Next. While at TPR he also served as the Assistant National Content Director for the MCAT through the transition from the old MCAT to the new MCAT. For his latter years with TPR he managed and ran school-based programs in the Austin ISD, including working directly with school and district administrators on program implementation and assessment.During a short stint with MasteryPrep, Doug developed, trained, and managed teachers that taught ACT and ACT WorkKeys and developed content for their ACT Science textbook and ACT WorkKeys class. In addition, he managed ACT prep programs in the South and Midwest and worked on and presented proposals for RFPs from districts in Texas.Starting in 2018, Doug began a new chapter of his life with Noodle Pros and also started his own publishing company, IcosaPrep, that produces primer textbooks for General Chemistry, Organic Chemistry, General Biology, and General Physics classes.
