About
Preethi Padmanabhan is a leading innovator in the field of advanced imaging and LiDAR systems, with a primary focus on single-photon avalanche diode (SPAD) technology and 3D-stacked sensor architectures. Her most impactful contribution is the development of a 256×256 45/65nm 3D-stacked SPAD-based direct time-of-flight (DTOF) image sensor for LiDAR applications, a landmark paper with 89 citations. This work introduced optical polar modulation to achieve up to 18.6dB of interference suppression, a critical breakthrough for enabling robust LiDAR in demanding environments like autonomous driving, drone surveillance, and augmented/virtual reality. By addressing the fundamental challenge of ambient light interference, Padmanabhan’s research directly enhances the accuracy and reliability of depth sensing in spacecraft navigation, assembly-line robotics, and advanced driver assistance systems (ADAS). Her achievements demonstrate a rare ability to bridge cutting-edge semiconductor design with real-world application requirements, positioning her as a key figure in the evolution of next-generation 3D sensing technologies.
