Handled the Metro Manila Subway Project and the North-South Commuter Railway Project.Ensures that environmental safeguards in the construction of a rail project are met by adhering to its commitment from its Environmental Impact Assessment (EIA) and warrants compliance to all environmental laws along with JICA guidelines for environmental and social considerations. Key Responsibilities• Performed functions of a pollution control officer, regularly audited environmental compliance report of contractors, ensured that government mandated permits are complete and up-to-date • Conducted environmental due diligence investigations, recommended methods for minimization and containment of pollution as well as greenhouse gases emission reduction programs • Liaised with other government agencies, development partners, NGOs, Project-affected families (PAFs) through public consultations and stakeholder meetings• Effectively handled and resolved complaints of stakeholders through acceptable legal channels and mechanisms

Performed research as a preemptive response to environmental and climate changes which focuses on carbon-neutral technology, climate change adaptation and integration of innovative technologies. Key Responsibilities• Primarily involved in research works on the transformation of organic contaminants in oxidative water treatment processes (UV/H2O2) • Identified structural and reaction mechanisms of micropollutants (MPs) through laboratory experiments and characterizations

This research project utilized advanced oxidation processes (AOPs) specifically photocatalysis for the effective removal of antibiotics in aqueous media including identification and quantification of transformation products, elucidation of reaction mechanisms and degradation pathways.Key Responsibilities• Worked mainly on the synthesis of graphitic carbon nitride (g-C3N4) based nanocomposites towards photodegradation of emerging contaminants like pharmaceutical and personal care products (PPCPs) in aqueous media• Conducted surface, chemical and optical characterizations of the synthesized material using highly technical laboratory techniques and equipment like HPLC, ICP, SEM, TGA, XRD, etc.Publications• Paragas, L.K.B., de Luna, M.D.G., Doong, R.-A., 2019, Insights into the rapid elimination of antibiotics from aqueous media by tunable C3N4 photocatalysts: Effects of dopant amount, co-existing ions and reactive oxygen species, Science of the Total Environment (2019), doi.org/10.1016/j.scitotenv.2019.03.003• Paragas, L.K.B., de Luna, M.D.G., Doong, R.-A., 2018, Rapid removal of sulfamethoxazole from simulated water matrix by visible-light responsive iodine and potassium co-doped graphitic carbon nitride photocatalysts, Chemosphere (2018), doi: 10.1016/j.chemosphere.2018.07.109

UNDP in partnership with the Philippine government undertakes the construction and rehabilitation of school buildings, emergency evacuation structures, and crisis centers located in various regions in the Philippines.Key Responsibilities• Involved in planning, cost estimates, monitoring and evaluation of the construction and rehabilitation projects. • Participated in the prequalification of contractors, evaluation of bids and awards to successful bidders• Formulated infrastructure policies, standards, and performed contracts management according to United Nations rules

Disaster risk reduction and climate change adaptation initiative of the Philippine government which aimed to produce an up-to-date, detailed, high resolution and three-dimensional (3D) flood hazard maps for the 18 major river basins in the country using Light Detection and Ranging (LiDAR) coupled with a hyperspectral and thermal imager.Key Responsibilities• Gathered elevation data using Light Detection and Ranging (LiDAR) sensors which scans flood plains of river basins to be used in flood modeling • Generated detailed resource information through GIS in various sectors namely, agriculture, aquaculture, forestry, and renewable energy mainly for natural resources management Publication• UP-TCAGP (2015), DREAM LiDAR Data Acquisition and Processing for Bohol River Floodplain, Disaster Risk and Exposure Assessment for Mitigation (DREAM), DOST Grants-In-Aid Program, 72 pp.
