Ricky Rajamanickam

I am a passionate environmental researcher with a strong background in wastewater treatment, waste-to-energy solutions, and emerging contaminants remediation. With a Ph.D. in Environmental Engineering and extensive industrial experience, I integrate research and practical applications to address sustainability challenges. My industrial experience in oil and gas operations, phycoremediation, and environmental monitoring further enhances my ability to connect theoretical knowledge with real-world applications.

With a commitment to sustainable development, I aim to contribute to academia by fostering student growth in research, encouraging application-oriented learning, and bridging the gap between academia and industry. My goal is to inspire the next generation of environmental professionals through innovative, hands-on, and impactful education.
