We actively work on the biology of seaweeds, especially their biodiversity, systematics, life history, and reproduction. We also dabble on algal community ecology, gravitating towards understanding the ecology of canopy-forming seaweeds such as Sargassum as well as other ecologically and economically important seaweeds such as red seaweeds Asparagopsis and Halymenia, and green seaweeds Ulva. Other research done by our team include floristics, marine phytogeography, and molecular phylogenetics.

Moreover, we conduct applied phycological research, with special reference to seaweed farming (i.e., mass cultivation of carrageenan-producing seaweeds Kappaphycus, Eucheuma, and Halymenia). Currently, we are scaling up on our efforts in harnessing underutilized seaweed resources by developing novel and/or locally-adapted cultivation technologies for large-scale biomass production of economically important seaweeds such as Ulva and Asparagopsis. This is to support the call of the seaweed industry to diversify our seaweed products.

Our team of young, budding scientists is led by one of the newest additions to the roster of faculty of MSI, Dr. Wilfred John E. Santiañez.

Projects

Biological and ecological studies on Asparagopsis taxiformis (BEAT) for culture technology development

A research designed to generate knowledge on the biology, field ecology, and physiology of the economically important red seaweed Asparagosis taxiformis to develop a locally-adapted culture technology for large-scale biomass production. Funded by the Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development (PCAARRD) of the Department of Science and Technology.

Diversity, systematics, and molecular phylogeny of Philippine Dictyotales (Phaeophyceae, Ochrophyta)

An exploratory work on the biodiversity and phylogenetic relationships of dictyotalean seaweeds. Funded by the University of the Philippines System Balik PhD Program (OVPAA-BPhD-2018-05).

Revisiting the systematics of the family Scytosiphonaceae (Ectocarpales, Phaeophyceae)

A continuing work aimed at resolving the complex systematic and phylogenetic problems in the brown algal family Scytosiphonaceae with special reference to the Indo-Pacific.

Establishing reference culture collections for marine macroalgae (seaweeds)

A work envisioned to document the seaweed resources of the Philippines through culture collections. Funded by U.P. Diliman – Office of the Vice Chancellor for Research and Development Ph.D. Incentive Award (Project No. 191926 PhDIA).

Biodiversity of cryptic marine brown algae

A closer look on the biology of microscopic (hence overlooked) brown seaweeds of the Philippines.

DNA barcoding of the Sargassum (Phaeophyceae) resources of northern Philippines

Assessing and validating Sargassum species records and distribution in northern Philippines. Funded by the University of the Philippines System Enhanced Creative Work and Research Grant (ECWRG 2018-02-010).

Status of the growth and reproductive timing of Sargassum in Pangasinan, Philippines

A work that seeks to understand the responses of Sargassum from the Bolinao-Anda Reef Complex (BARC), Pangasinan, north-western Philippines to environmental changes especially ocean warming. Funded by the Nagao Natural Environment Foundation Research Grant Programme (Japan).
