Dr. Grecebio Jonathan D. Alejandro is a Full Professor V at the College of Science and currently the Director of the Office for Graduate Research, Faculty of the Graduate School, University of Santo Tomas (UST). He finished his B.Sc. in Biology at the Far Eastern University in October 1992, M.Sc. in Biological Science at the University of Santo Tomas, Magna Cumlaude in 1999 and doctoral degree (Dr.rer.nat) in Plant Molecular Systematics and Evolution from the University of Bayreuth, Bavaria, Germany, Magna Cumlaude in 2005 through the Deutscher Akademischer Austauschdienst (DAAD) Doctoral Fellowship. Dr. Alejandro further strengthened his research endeavor when he was awarded the prestigious European fellowship, the Alexander von Humboldt (AvH) Postdoctoral Fellowship for two years (2009-2010). During his Humboldt fellowship, he was a visiting scientist in the Natural Museum of Stuttgart, Germany; Université de Franche-Comté, Besançon, France; and University of Bayreuth, Germany. A Humboldt Return Fellowship was also awarded in 2011 to continue his research works back in the Philippines. He was re-invited twice (2015 and 2019) as a Visiting Scientist in Germany supported by the Humboldt Foundation.

Dr. Alejandro is recognized for his pioneering research on Plant Molecular Phylogenetics in the Philippines and discovery of novel genera and several new endemic species in Rubiaceae (coffee family). Over 80 Plant names authored and/or co-authored by Dr, Alejandro based on International Plant Name Index (IPNI) https://www.ipni.org/a/20004669-1. He established the Thomasian Angiosperm Phylogeny and Barcoding Group (TAPBG) in the UST - Research Center for the Natural and Applied Sciences. It puts special focus on systematics and taxonomy, molecular phylogenetics, biodiversity, DNA barcoding of medicinal plants and studies on the phytochemistry and biological potentials of endemic Philippine plants. The TAPBG has been a major research force when it comes to documenting the rich biodiversity of Philippine Rubiaceae and medicinal plants as well as the preservation and conservation of endemic plants. He has supervised 12 doctoral students, 22 master’s and more than 90 bachelor’s theses from 2006-to present. He is currently mentoring four Ph.D., five M.S. and two undergraduate thesis writers. Dr. Alejandro has presented over 50 papers in international fora and over 200 papers in local scientific meetings either as lectures and/or posters. As a testament to his incomparable scientific accomplishments, the TAPBG has been cited/awarded in a number of scientific fora as Best Lecture, Best Poster, Winners of Young Scientists Forum in national (e.g., ASBP, BIOTA, NAST-ASM, NRCP, PhilSAgen, PSBMB) and international conferences (e.g., AABE, ICONS, Flora Malesiana).

Dr. Alejandro received a research grant from the DOST– Philippine Council for Health, Research & Development (PCHRD) in which he is a project leader in DNA barcoding of Philippine medicinal plants. This project constitutes a pioneering genome-based authentication of Philippine medicinal plants with promising chemical and pharmacological properties. It aims to develop a Philippine Medicinal Plants DNA Barcode Database (PMPDBD). Dr. Alejandro is also the project leader of two other projects funded by the National Research Council of the Philippines (NRCP) and CHED-PHERNet dealing with molecular phylogeny and taxonomic revisions of endemic Philippine Rubiaceae. His group utilizes both classical tools and several molecular markers from cpDNA and nrDNA to resolve problematic taxa as well as bioinformatics software in editing, aligning, and constructing phylogenetic trees.

To date, Dr. Alejandro has published more than 150 articles, over 100 papers are ISI/Scopus indexed with H-index=23 and more than 1,700 citations based on Google Scholar. He is among the top 5 best Scientists of UST based from AD Scientific Index. He was awarded the 2020 PSBMB Distinguished Research Award given by the Philippine Society of Biochemistry & Molecular Biology, the 2017 St. Antoninus of Florence Outstanding Alumnus

Award (UST-Graduate School), and 2015 Gregorio Y. Zara Achievement Award last September 2015 given by the Philippine Association for the Advancement of Science (PhilAAST). He was also awarded by the DOST-NAST ASM 2015, the Outstanding Scientific Paper Award and the 2014 OUTSTANDING RESEARCH AND DEVELOPMENT AWARD for Basic Research with the Eduardo A. Quisumbing Medal during the National Science & Technology Week (NSTW). He has received numerous awards including the 2006 NAST Outstanding Young Scientist in Biology (Botany), 2008 NAST Talent Search for Young Scientist, 2011 NAST Best Scientific Poster Award, 2013 Hall of Fame Award (Gawad San Lorenzo Ruiz, UST), 2012 Best Published Research in S&T (Gawad San Alberto Magno, UST); 2011 Outstanding Researcher (Gawad San Alberto Magno, UST); 2008 Best Associate Professor (Gawad Santo Tomas, 2008); 2004 Marie Stopes Award (XXIII Willi Hennig Society, Paris, France); 2000, 2003, 2005 Silver Series Awardee; 2005 to 2021International Publication Awards; 2012, 2014, 2017 Gold Series Awardee (Office of Research and Innovation, UST).

Dr. Alejandro actively participates in several local and international professional organizations and is currently the president of the Alexander von Humboldt Assoc. of the Philippines (AvHP) and former president of the Association of Systematic Biologists of the Philippines (ASBP), and the treasurer of the Philippine Society for Biochemistry and Molecular Biology (PSBMB). He does several extension services/professional consultancies such as Section Editor in Taiwania and Phytotaxa International journals and Associate Editor in The Antoninus Journal, Philippine Journal of Systematic Biology, Acta Manilana Journnal, Reviewer in several National & International journals and DOST/DOH project proposals, Adviser and Evaluator of graduate thesis/dissertation, Consultant/ UST representative to the Philippine Plant Conservation Committee headed by the DENR – Biodiversity Management Bureau, and importantly his advocacy in conserving Philippine endemic plants.
