Meghna Roy Chowdhury

PhD Student, Electrical & Computer Engineering @ Purdue University

"Arise, Awake & Stop Not, till your goal is reached!"

Hello there! I'm Meghna, a PhD student in ECE at Purdue University, focusing my doctoral research on low-power wearable tech and AI in healthcare, while also bringing experience in applied ML for circuit optimization and hardware security.

My research involves system-level applications combining low-power sensing, communication, and analysis of various biopotential signals. I utilize techniques from Signal Processing, Machine Learning, Deep Learning, and Computer Vision, and also work on data collection and building predictive models.

Currently researching at SPARC Lab, I enjoy blending hardware and software skills to create impactful solutions.

To sum it up: I am a passionate, hands-on, and always-ready-to-learn-and-apply-new-tech kind of individual, seeking opportunities to contribute my best in the domains of healthcare AI, low-power wearables, circuits, and secure intelligent systems.
