Janith Godakawela, PhD in Mechanical Engineering-Engineering Mechanics, 2026
I would like to express my sincere gratitude to the Graduate School and the Graduate Dean Awards Advisory Panel for the Finishing Fellowship award. I would like to sincerely thank my advisor, Dr. Bhisham Sharma, for his continued guidance and support throughout my doctoral journey.
I earned my B.S. in Aerospace Engineering from Wichita State University in 2021, where I also began my PhD before transferring to Michigan Tech in 2023 to continue my research under Dr. Sharma. My dissertation focuses on the design and optimization of additively manufactured acoustic liners for aerospace applications. Using 3D printing, I develop architected porous structures and investigate how their geometry can be tailored to achieve targeted sound absorption characteristics. My work spans computational modeling, experimental acoustic characterization, and aeroacoustic validation under conditions representative of aircraft engine environments. Through collaborations with industry and government partners, I have been able to test and refine these designs beyond idealized laboratory settings, confirming their potential for real world noise control applications.
Alongside my research, I have had the opportunity to contribute to teaching through assistantships and grading, as well as mentoring senior design teams and undergraduate researchers. I have also had the pleasure of being a founding member of the Acoustical Society of America student chapter at Michigan Tech, where I currently serve as the national representative.
As I complete my dissertation, I am grateful for the support this fellowship provides. I look forward to pursuing an academic career where I can continue contributing to mechanical and aerospace research and mentoring the next generation of engineers.
