Marvin Altamia

Marvin graduated from the University of Santo Tomas where he obtained a Bachelor of Science in Biochemistry. He is currently studying the microbial symbionts of shipworms under the PMS-ICBG Project. Marvin is known for having a green thumb in cultivating numerous novel endosymbiotic bacteria. Whole-genome analysis of the microbes he cultured showed that they contain numerous secondary metabolite gene clusters which indicate their potential for drug discovery. He is also the official photographer of the PMS-ICBG Project who is tasked in documenting scientific research specimens and science geeks’ behaviour in their natural habitat. His artsy-fartsy photos can be found here. You can email him at marvin.altamia @ gmail >>dot<< com

Noel Lacerna II

Noel received his bachelor’s and master’s degree in Chemistry at University of the Philippines-Diliman focusing on microbial chemistry. He is currently working on the PMS-ICBG Project as a chemist looking for small molecules from mollusk-associated symbionts. His research interests include chemical ecology, spectroscopy, natural products chemistry and synthetic biology.
Outside the lab, Noel likes to spend his time outdoors through hiking. One of his wishes in life is to drink brewed coffee on a mountaintop.



Jessa Mae Laude

The experience and learning I gained from the Concepcion lab made me appreciate natural product-based drug discovery.  I was exposed to the traditional bioactivity-guided isolation of marine (MMOs) and terrestrial (Moringa oleifera) natural products which enabled me to identify some known compounds (i.e. thiocarbamate and nitrile glycoside) with new bioactivities. The bioactivity-guided isolation approach is time-consuming, labor-and cost-intensive process, thus exploring the metabolic profiling approach will be an interesting milestone for me. I was given the opportunity to study the Moringa plant and its antitumor potential. The said project has stirred my interest in herbal medicine as a source of nutraceutical or lead compounds/enriched fraction for drug development. Concepcion lab has hosted several local and international gatherings of researchers, so aside from labwork I was also exposed to the production and behind-the-scenes of conducting scientific conferences. I am currently involved in the  PMS-ICBG Project, mainly tasked to oversee the status of finances and other administrative-related stuff. I obtained my BS in Chemistry from the University of the Philippines-Visayas. I can be reached at

Bailey Ward Miller

Bailey graduated from the University of California, Santa Barbara in 2009 with BS in Biopsychology. During his time at UCSB his research focused on the neurochemical adaptations to drug abuse. Upon graduation, Bailey decided to marry his research interests in drug discovery and pharmacology with his passion for scuba diving and marine life by joining the graduate program at Scripps Institution of Oceanography. Here, working in the lab of Dr. William Gerwick, Bailey’s work entered the field of marine natural products, working on the isolation and characterization of natural product compounds from marine cyanobacteria with activity against the human cysteine cathepsin proteases. Upon completion of his doctoral dissertation, Bailey joined the PMS-ICBG team in 2016.

As the postdoctoral research fellow for the PMS-ICBG Project, Bailey spends his time working in both the University of Utah and the Marine Science Institute at the University of the Philippines. His current research interests include metabolomics profiling of mollusk associate bacteria, high throughput screening of extract libraries for drug discovery, and integrated approaches for rapid dereplication, isolation, and characterization of novel natural products from these organisms.

DSC_1779Jose Miguel Robes

Miguel first joined the lab as an undergraduate thesis student working on natural products from marine sponges, after obtaining his Bachelor’s degree in Biology from the University of the Philippines Baguio, he officially joined the group under the PMS-ICBG Project. Miguel is currently pursuing his MSc Microbiology degree from the Institute of Biology under the guidance of Dr. Gisela Concepcion and Dr. Joyce Ibana. He is interested in developing assays against infectious diseases and understanding microbial interactions and its effects on the production of biologically important molecules.



Jortan Tun

My first project in the lab was on influenza vaccine (with Dr. Eduardo Padlan) where the goal is to produce recombinant “de-antigenized” hemagglutinin that will confer protection against cladal influenza strains. My work here is mainly on the immunological characterization of the recombinant hemagglutinin using in vitro and in vivo antigenicity and immunogenicity assays. Then, I became involved in two of the largest marine drug discovery projects in the Philippines: PharmaSeas and  PMS-ICBG Project. Most of my work involved cell-based assays for bioactivity screening of extracts or pure compounds from mollusk- and sponge-associated bacteria. These assays include anti-cancer, antiviral (HIV and influenza), antibacterial, anti-fungal, and anti-biofilm. I was also involved in the Moringa project where we used flow cytometry and 4T1 metastatic tumor mouse models to characterize the bioactivities of potential chemotherapeutic and chemopreventive compounds isolated from the leaves and seeds. Currently, my research focuses on identifying synergistic drug combinations and determining their mechanisms of actions. I am also very much interested in the neuroactivity testing of small molecules from mollusk-associated bacteria and peptides from cone snails using calcium imaging on primary cultures of mouse dorsal root ganglion (DRG) and trigeminal neurons. As an in-house research associate, I am also in-charge of several administrative duties and laboratory management.
