Educator-researcher focusedis on environmental monitoring, STEM education, and sensor-based data collection in middle and high school settings. My work involves designing and guiding student-led investigations using microcontrollers (Arduino, ESP32, Adafruit), LoRa communication systems, and digital sensors to explore topics such as air quality (CO₂, VOCs), atmospheric pressure, water quality (Oxygen, Alkalinity, turbidity, pH), and soil moisture. Project-based learning, citizen science, environmental engineering, data literacy, IoT applications in education, youth-led environmental research, and bilingual STEM curriculum development.
