Teaching Interst

As a Lecturer in Environmental Science, I teach undergraduate courses covering biodiversity, ecology, wildlife conservation, marine science, pollution control, analytical chemistry, and biomolecular separation. My teaching approach combines theoretical knowledge with practical activities, field observations, case studies, laboratory exercises, and research-based learning. I encourage students to apply scientific concepts to contemporary environmental challenges, particularly those relevant to Sri Lanka. 

ENS2112 : Biodiversity and Conservation

• This course introduces the concepts, levels, values, and distribution of biodiversity. It also examines threats to biodiversity, conservation strategies, protected-area management, ecological restoration, and national and international conservation frameworks. 

ENS2252 : Ecotourism

• This course explores the principles and practices of responsible nature-based tourism. Key areas include sustainable destination planning, community participation, visitor management, environmental interpretation, biodiversity conservation, and the social and economic impacts of ecotourism.

ENS2222 : Applied Ecology and Community Environment

• This course focuses on applying ecological principles to understand and manage interactions between human communities and their environment. It covers ecosystem processes, community-based conservation, natural-resource management, environmental health, and sustainable development.

ENS3152 : Wildlife Ecology and Conservation

• This course examines wildlife populations, habitats, behaviour, ecological interactions, and conservation needs. Students learn methods of wildlife monitoring, habitat assessment, population management, human–wildlife conflict mitigation, and threatened-species conservation.

ENS3262 : Marine Environment and Management

• This course introduces marine and coastal ecosystems, including coral reefs, mangroves, seagrass meadows, salt marshes, lagoons, and estuaries. It also addresses marine biodiversity, coastal-resource use, environmental threats, marine protected areas, and integrated coastal-zone management.

ENS2263 : Environmental Pollution and Control

• This course examines the sources, pathways, effects, monitoring, and management of environmental pollutants. It covers air, water, soil, noise, thermal, light, odour, radioactive, and solid-waste pollution, together with pollution-prevention and control technologies.

Teaching and Learning Approach

My teaching philosophy emphasises student-centred and experiential learning. Depending on the course, teaching activities include:

• Interactive lectures and guided discussions

• Laboratory practical sessions

• Field visits and ecological surveys

• Case studies based on Sri Lankan environmental issues

• Group assignments and student presentations

• Research-based learning activities

• Data analysis and scientific-report writing

• Continuous assessment, quizzes, and reflective learning

Through these activities, I aim to develop students’ scientific knowledge, practical competence, critical-thinking ability, environmental responsibility, teamwork, and professional communication skills.
