Sabiju Valiya Valappil joined ImPhys as Post-Doc
Sabiju Valiya Valappil will be working on the PostDoc project entitled "Integrated photonics-based sensors for Bragg peak localization using ultrasound," where the focus will be to develop a highly sensitive ultrasound sensor that possesses a broad operational frequency range for detecting ultrasound pulses from the interaction between the proton beam with the ultrasound contrast agent.
After completing his master's in Mechanical Systems Design from the Indian Institute of Technology, Kharagpur (India), he worked at Caterpillar INC (heavy machinery industry) as a research engineer for three years, where he handled projects on dynamic analysis tool development, finite element analysis, and machine performance analysis using data science. After a brief stay in the USA, Sabiju started his Ph.D. in the department of Precision and Microsystems Engineering, 3ME Faculty, in 2018.
Here he investigated the potential of phononic crystals -- artificial materials possessing band gaps (frequency ranges where mechanical waves do not propagate) – to improve the measurement accuracy of ultrasonic flowmeters. The project is sponsored by an industrial partner Krohne. He has conducted analysis, design, and experimental validation of phononic crystal's performance in wave rejection and wave steering applications.
