On Faith

SR. ANGELA HOFFMAN joined the faculty at University of Portland in 1989 as a biochemistry and chemistry instructor. In the early ’90s, she began working with undergraduate and high school students who were interested in taxol (paclitaxel), a natural-source cancer drug derived from yew tree bark and used in fighting breast, ovarian, and lung cancers, as well as Kaposi’s sarcoma. Through lab experimentation, Hoffman and her students ascertained that taxol could also be exported into a culture medium from the cuttings of yew trees. This new discovery led to the first of four of Hoffman’s patents. She proudly shares ownership of this first patent with her students.

As she contemplates packing up her office, Hoffman estimates that in addition to the more than 6,500 undergraduate students she has taught, she has worked on research projects with at least 300 undergraduates and nearly 100 high school students. Among her honors, she has been named an American Chemical Society Fellow, a Fellow with the American Association for Advancement of Science, an Oregon Academy of Science Outstanding Higher Ed Teacher, and was given an honorary doctorate from St. Martin’s University. But she isn’t concerned with her legacy. She likes to fly under the radar; she says, “The point is: what can you discover? And who can you help?”

Hoffman’s commitment to her students is well-recognized on campus. Mellonie Mwawai, a research mentee of Hoffman’s at UP and a 2021 graduate says, “literally everyone loves her!”

An immigrant from Kenya, Mwawai struggled with self-identity her freshman year. Hoffman was Mwawai’s first-year general chemistry instructor and perceived she was in distress. Hoffman showed Mwawai a plant from her campus greenhouse and invited her to begin a research project using it. Mwawai recognized Plectranthus amboinicus, a plant that grows in Kenya. “My grandma used it as a food additive and a medicine for stomachaches and open wounds. It was like the ibuprofen and Tylenol for everything.” The research project gave Mwawai a sense of purpose. Working with the plant “was like something from home. And that switched my perspective on everything,” she says.
