While a NATO scholar, he did postdoctoral studies on cell biology using the electron microscope and microcine at the University of Bonn and the University of Leeds. For 10 years, he taught botany and related subjects at several universities (UMass Amherst, UCLA, and WWU).

Dr. Drum studied herbal medicine with Ella Birzneck, president of Dominion Herbal College, for 12 years, and taught at the school’s summer seminars for 35 years. He has been an adjunct faculty member at Bastyr University since 1984, and he lectures at major herbal conferences and herbal schools.

He continues to work as a medicinal herb wildcrafter and herbal educator, specializing in seaweed therapies and thyroid issues.
