  • Biography

    During his graduate studies, Wael worked on projects spanning the fields of computational ocean acoustics and wave scattering using state-of-the-art numerical modeling, uncertainty quantification, and Bayesian inference techniques. Applications of his work included probabilistic acoustic predictions, acoustic inversion and tomography, and seafloor mapping. At MERL, Wael is interested in developing reduced-order and stochastic modeling methods for forward and inverse problems arising in computational sensing.

    •  TALK    [MERL Seminar Series 2024] Fadel Adib presents talk titled Decoding Hidden Worlds: Unprecedented Sensing and Connectivity for Climate, Robotics, & Smart Environments
      Date & Time: Wednesday, April 3, 2024; 12:00 PM
      Speaker: Fadel Adib, MIT & Cartesian
      MERL Host: Wael Hajj Ali
      Research Areas: Computational Sensing, Dynamical Systems, Signal Processing
      Abstract
      • This talk will cover a new generation of technologies that can sense, connect, and perceive the physical world in unprecedented ways. These technologies can uncover hidden worlds around us, promising transformative impact on areas spanning climate change monitoring, ocean mapping, healthcare, food security, supply chain, and even extraterrestrial exploration.

        The talk will cover four core technologies invented by Prof. Adib and his team. The first is an ocean internet-of-things (IoT) that uses battery-free sensors for climate change monitoring, marine life discovery, and seafood production (aquaculture). The second is a new perception technology that enables robots to sense and manipulate hidden objects. The third is a new augmented reality headset with ``X-ray vision”, which extends human perception beyond line-of-sight. The fourth is a wireless sensing technology that can “see through walls” and monitor people’s vital signs (including their breathing, heart rate, and emotions), enabling smart environments that sense humans requiring any contact with the human body.

        The talk will touch on the journey of these technologies from their inception at MIT to international collaborations and startups that are translating them to real-world impact in areas spanning healthcare, climate change, and supply chain.
