Grenfell Campus's School of Science and the Environment reached a milestone moment with the conferring of its first PhD in boreal ecosystems and agricultural sciences (BEAS). 

Dr. Sashini Pathirana, as the first PhD graduate from Grenfell Campus, received the great honour with a thesis titled “Integrated Ground Penetrating Radar – Electromagnetic Induction Techniques to Support Precision Agriculture by Assessing the Effects of Agricultural Practices.” The thesis demonstrates her innovative approach to advancing precision agriculture through an integrated geophysical approach – a significant contribution to the field of Hydro-geophysics.

"The BEAS program at Grenfell Campus provided an enriching environment, allowing me to grow as a researcher, collaborate with experts in my field, access state-of-the-art resources, and present my findings at international conferences," said Dr. Pathirana. "This journey not only strengthened my expertise in hydro-geophysics but also allowed me to grow personally and professionally, surrounded by a vibrant and supportive community. I’m grateful for the opportunities it brought." 

She said her research focused on using geophysical tools such as GPR and EMI to understand better how agricultural practices affect soil properties, variables and structure with the goal of advancing precision agriculture. These findings will hopefully be of benefit to farmers, scientists and the environment.

During her doctoral journey, Dr. Pathirana published four peer-reviewed articles in high impact journals – three in Q1 rankings (top 25% of journals) and one in Q2 rankings (25-50%) – one conference paper, and 12 conference abstracts, including international conferences, and received six awards showcasing her dedication to compelling and innovative research.   

Dr. Lakshman Galagedara, Dr. Pathirana’s supervisor and a professor in the School of Science and Environment, said it was a proud moment for all involved.

“Sashini exemplifies the best of what Grenfell Campus stands for – rigour, innovation and dedication to addressing global challenges,” he said. “Her work has made significant contributions to the field of hydro-geophysics.”

Dr. Mumtaz Cheema, associate vice-president (Grenfell Campus) Research and Graduate Studies, said Sashini’s success is a reflection of the excellence and commitment of the BEAS faculty..

“This achievement indicates that Grenfell Campus continues to be a leader in academic excellence and innovative research,” he said. “Sashini’s success is the result of the diligence and expertise of our faculty and the support of our community, and indicates the limitless potential of our students.” 

The School of Science the Environment also offers a master’s degree in boreal ecosystem and agricultural science. To learn more about these and other graduate programs, visit https://mun.ca/grenfellcampus/programs--schools/graduate-programs/.
