Zeeshan Ahmed

A spectroscopist by training, Zeeshan Ahmed joined the Thermodynamic Metrology Group at NIST in 2012. His research activities focus on the development of novel, disruptive technologies that aim to replace legacy-based measurement platforms. Specifically, his current research is focused on the development of physics-constrained machine learning models for photonic sensors. This line of inquiry seeks to enable a cost-effective, integrated multi-functional photonic sensor package with intelligent-calibration capabilities.

Zeeshan Ahmed was awarded the Bronze medal for superior service in 2016 and the Equal Employment Opportunity Award in 2015 for his work with socio-economically disadvantaged students. He currently serves as the Chairman of Task group on Emerging Technologies under Contact Thermometry at the BIPM. In addition, he holds an Affiliate Faculty position with George Mason University’s Chemistry department and the Quantum Science and Engineering Center (QSEC) where he collaborates with fellow members on the development of disposable, embedded sensor networks for tissue engineering applications.
