Spearheading UI/UX design and development of highly usable human-machine interfaces (HMI) for autonomous trucks while considering the needs of stakeholders such as engineers, truck operations, triage, customers and investors. * Designed and implemented a new autonomous vehicle UI for our trucks. Demonstrated improvement of the UX for internal-, investor- and customer-facing technology demonstrations. * Rearchitected legacy JQuery-based UI code to use React.js, Bootstrap.js and MobX for better modularity, maintainability and extensibility of Kodiak's UI software stack.* Optimized THREE.js/WebGL 3D vehicle and sensor visualization for improved performance and visual esthetics.Technologies: React | Three.js | MobX | WebPack | JavaScript | C++ | Bazel

HMI for Autonomous VehiclesDeveloped patent-pending audio-based warning HMI for autonomous vehicles, augmenting situational awareness for drivers and engineers of autonomous trucks in safety-critical situations.Trajectory PredictionEngineered machine learning models for trajectory prediction of other vehicles in critical traffic situations. This involved data extraction from vehicle dataset bags, dataset preparation, model training, automated benchmark development and integration in online vehicle stack.

Bootstrapped an offshore team of 10 AI engineers and researchers with a focus on commericalizing Harman X AI products. Showcased industry-first driver monitoring system at CES 2019.

Senior Principal Engineer in the HARMAN FX Team, the organization's most forward-looking group, executing advanced projects and reverse-engineering science fiction, every day. * Advanced Automotive Driver Monitoring System (DMS)Architected and implemented an advanced automotive driver monitoring system that is trained with best-in-class AI models that understand the driver's cognitive and emotional state. Our system allows combining AIs for vehicle control and driver understanding to create the best possible user interface for autonomous vehicles. Cornerstone of HARMAN exhibit at CES 2019.* Robotic Vehicle HMIDesign, implementation and evaluation robotic shape-shifting vehicle HMIs for level 3-5 autonomous vehicle control, to be deployed in upcoming high-end vehicle of major auto OEM.

* Activity Recognition using RF SensorDeveloped an activity recognition system that is able to accurately recognize activities of desktop office workers and retail clerks / customers using data from RF radar sensors embedded under the work surface.* Through-the-screen Robot Navigation UIOperating telepresence robots manually can be cumbersome. We developed a natural user interface for robot teleoperation that allows the driving of robots by simply clicking on a location in the camera feed. This eases the burden on the operator and makes the process of navigating a robot around a space much more enjoyable.* Thermal-Haptic Interactive SurfaceInvented the world's first interactive surface that uses resistive heating and liquid cooling to generate thermal feedback in form of thermal pixels. This provides user interfaces or interactive content with an additional thermal feedback channel. Due to its simplicity of the design and economies of scale afforded by liquid cooling, we are able to scale thermal-haptic interactive surfaces to very large surface areas and a high numbers of thermal pixels. * AirAuth: Gesture-Based Authentication SystemAirAuth is a gesture-based authentication system that uses in-air hand gestures tracked by a short range depth camera to perform user authentication. AirAuth supports personalized user password gestures and is resistant against smudge and shoulder surfing attacks.
