A native of Iloilo, Dr. John Dale Dianala is an Assistant Professor at the University of the Philippines - National Institute of Geological Sciences. His research focuses on understanding where, how often, and why earthquakes happen by studying how tectonic faults accumulate and release stress. He primarily works with satellite radar (InSAR) and GPS data to map and model earthquake sources and the seismic cycle, and high-resolution digital elevation models to tease out the 'scars' of past earthquakes in the landscape. JD also uses remote sensing data in aid of earthquake quick response. He obtained his Bachelors and Masters of Science degrees in Geology at UP Diliman, and his PhD in Earth Sciences from the University of Oxford in 2021. Aside from his research, JD takes watching films very seriously.

Ms. Lala Grace Calle is currently an editor at Cactus Communications. She holds a Bachelor of Science in Fisheries from the University of the Philippines Visayas and is currently pursuing a Master of Marine Science at the University of the Philippines Diliman. From 2017 to 2021, she worked with the Coral Reef Ecology Laboratory, where her team concentrated on assessing the status of giant clams in the Philippines. In 2022, she was among the researchers stationed on Pag-asa Island to evaluate the surrounding coral reefs. Her research interests lie in molluscan behavior and behavioral ecology, with a particular focus on the activity patterns and foraging behavior of the helmet shell, Cassis cornuta.

Ms. Ruth Esther Delina-Agillon is a PhD student specializing in environmental mineralogy and geochemistry at the Interface Geochemistry section of the GFZ German Research Centre for Geosciences. She obtained her MSc in Geology from the University of the Philippines Diliman, where she also served as an instructor. Her passion for teaching and research led her to extend her MSc work on Philippine nickel mining areas through the DAAD German Academic Exchange Service Doctoral Research Grant. The main goal of her PhD research is to trace the fate of potentially toxic metals, such as chromium, in these mining areas for water quality management.

Ms. Joy Santiago is a geographer and licensed environmental planner, currently serving as the only female Chief Science Research Specialist at the University of the Philippines Resilience Institute. She is also the Director of the Internal Audit Division at the Centre for Neighbourhood Studies Philippines. Ms. Santiago taught spatial analysis and cartography using geographic information systems at Miriam College for nearly a decade. She was a fellow at the American Geoscience Union Thriving Earth Exchange Program and the International Visitors Leaders Program for Disaster Preparedness and Emergency Management. In 2016, Ms. Santiago was honoured with the European Geosciences Union Outstanding Student Poster and PICO Award for her team's project, "Development of Storm Surge Hazard Maps and Advisory System for the Philippines." Throughout her career in geography and environmental planning, Ms. Santiago has assisted local government units across the Philippines in formulating risk-informed land use and development plans.

Michael Y. Roleda is a Professor at the Marine Science Institute of the University of the Philippines-Diliman. His passion for tropical seaweeds started in the early 1990s cataloguing their biodiversity and worked on the biology and biochemistry of an agarophyte, Gelidiella acerosa. Further graduate study and postdoctoral fellowships in Germany, Sweden, and Scotland enabled him to work on cold-temperate and polar seaweeds and microalgae with emphasis on their physiological responses to global climate change stressors (e.g., UVR, ablation-derived sedimentation, ocean warming and acidification, and eutrophication). In 2004, he went bipolar– participated in land-based expeditions to Spitsbergen in the Arctic and King George Island in the Antarctic. His search for a niche brought him to the Southern Ocean in New Zealand (2010) and then back to the North Atlantic in Norway (2014), where he started working on the food and feed applications of seaweeds. He came full circle in 2018– back in the Philippines working on the biodiversity of carrageenan-producing eucheumatoids (Kappaphycus spp., Eucheuma denticulatum, and Betaphycus gelatinus, among others), led and improved the in vitro and hatchery gene banks with >200 unique strains undergoing genotypic and phenotypic characterizations, understanding their ecological breath and susceptibility to pest and diseases, and innovating mitigating measures.
