The young Department started with only two sections and the first graduates was in 2011. The active participation of the faculty and undergraduate students to research and the numerous scholarships and awards received had garnered attention from the PUP community and at the national level. By 2013, chairperson Dr. Alvarez was concurrently the Director of PUP Institute for Science and Technology Research that created the different centers of research which generally implemented a research policy mostly from the biological discipline. From 2014 – 2016, the Department was chaired by Dr. Armin S. Coronado. During the years 2010 – 2016, laboratories in Phycology and Microbiology, and the PUP Herbarium were established that accommodated teaching demonstration and research works of the Department’s faculty and students. 

On the early part of 2017, Dr. Alvarez came back from a postdoctoral training and returned as the Department chair. However, she opted to become a full-time faculty researcher and built the Mycology and Nematology laboratories in 2018. She passed the torch in 2018 to the capable hands of the Department’s current Chairperson, Assoc. Prof. Carmelita P. Mapanao. 

To meet the development and the broadening of Biology as an academic discipline, the curriculum of the BS Biology program was revised in 2018 and now offered three (3) specialization tracks: Microbiology, Plant Biology and Animal Biology. Since then, the program now caters five sections of BS Biology students per Year Level.

Faculty roster has also increased, facilities improved, and extensions were implemented that enabled the Department to achieve a Level II re-accreditation from the Accrediting Agency of Chartered Colleges and Universities in the Philippines (AACCUP), Inc. in 2021. 

For seventeen years, the Department of Biology of Polytechnic University of the Philippines of A. Mabini Campus has been a home to a growing number of highly motivated researchers, health practitioners & educators of biological science with profound awareness & respect to principles governing the science of life. Guaranteed to be equipped with technical proficiency and research and extension capabilities, the faculty and students of the Department are proactive and engaging members of the society in creating sustainable communities and are committed to excellence and service to the nation.
