Peter Gruber is the author of numerous articles and presentations. He won a National Science Foundation grant to modernize Mount Holyoke's physiology curriculum and another to examine the nuclear envelope in higher plants. Gruber is associated with organizations such as Sigma Xi, the American Society of Plant Physiologists, and the American Association for the Advancement of Science.
Gruber taught introductory courses in biology as well as senior-level seminars on plant biology. In addition, he has participated in the Howard Hughes Summer Research Training Fellowships for first-year students.
