"In Pursuit of Innovation, Interdisciplinary Collaboration, Internationalization & Inclusive Development"

Doctor of Philosophy in Botany


Brief description of the major field

The PhD Botany program is part of the post-baccalaureate degree offerings of the Institute of Biological Sciences administered by the UPLB Graduate School. Its main goals are to develop the ability of the students to undertake critical inquiry and independent research in the plant sciences leading to their substantial contribution to this field, to widen their field of knowledge, as well as to develop their professional leadership. Its first graduate can be traced in 1972 when this program was then offered by the Department of Botany of the College of Sciences and Humanities. With the renaming of the College of Sciences and Humanities to the College of Arts and Sciences in 1977, this program continued to grow and flourish at the Institute of Biological Sciences formally established in 1983. The program at present has a current teaching staff of 11 graduate faculty members (9 doctoral and 2 master degree holders) who are experts in various fields of botany.

UP and Nagoya University (NU), through President Alfredo E. Pascual and UPLB Chancellor Fernando C. Sanchez, Jr. and NU President Seiichi Matsuo, respectively, have inked an agreement for UPLB to host the Nagoya University Asian Satellite Campus (NUASC) through the UPLB Graduate School.

This agreement makes the Philippines the eighth country to host the NUASC through which the Transnational Doctoral Programs for Leading Professionals in Asian Countries will be implemented. This will enable Filipino doctoral candidates to enroll in NU doctoral programs without having to be physically present in Nagoya for the whole duration of the course.

The agreement was formalized at the Executive Conference Room in BM Gonzalez Hall, UPLB on Dec. 2. Dr. Jose V. Camacho, Jr., dean, Graduate School and Dr. Fumio Isoda, director, Nagoya University Asian Satellite Campuses Institute, served as witnesses of the signing of the memorandum of agreement (MOA). read more

UPLB and Nagoya University (NU) formally opened the NU satellite campus in the Philippines and held the International Symposium on the Internationalization of Graduate Education at Acacia Hotel in Alabang, Muntinlupa City on March 8.

UPLB Chancellor Fernando C. Sanchez, Jr.  said in his message during the opening program that to be a globally competitive research and graduate university, UPLB must pursue joint programs and collaborative activities with international academic and research institutions. He cited as an example the Philippines Transnational Ph.D. Program for Leading Professionals in Asian Countries being implemented by UPLB and NU.  

UP President Alfredo E. Pascual added that the program takes the University to a higher level and a step closer to being a globalized institution in terms of research and graduate education.  It will also allow experts to build lifelong partnerships with NU without leaving the country. He issued a challenge for UPLB to become a leader in global intellectual conversations of tomorrow. read more

The Graduate School (GS) and the College of Public Affairs and Development (CPAf), together with UP Mindanao, launched the Mindanao Development Studies Seminars (MDSS) on May 13-14 at UP Mindanao, Davao City.
