He worked there as a research assistant and teaching assistant before pursuing his PhD at UCSB.At UCSB, Mubayi worked in the O’Malley Lab, where his research focused on anaerobic bacteria that can break down lignin, a tough component of plant matter.His work explored biological approaches to converting plant waste and plastics into more sustainable alternatives to petroleum-based materials.

Researcher and avid outdoorsman

Mubayi was also passionate about hiking, tennis and cycling. In 2022, he took part in Illini 4000, a student-led nonprofit initiative, cycling from New York to San Francisco to raise money for cancer research and patient support services.His family had described him as a fairly experienced hiker in their earlier appeal for help. A university profile also noted his interest in applying chemical and biological engineering to environmental sustainability and climate change.
