Research and Development

UC Berkeley

Dr. Lavian served as an Industry Fellow and Lecturer in UC Berkeley’s Industrial Engineering and Operations Research (IEOR) Department and at UC Berkeley Engineering’s Sutardja Center for Entrepreneurship and Technology (SCET). He has taken part in UC Berkeley’s startup accelerator, SkyDeck, as principal investigator of the wireless RF signal startup company, CRadar.Ai, and co-founder, CEO, and CTO of smartphone wireless telecommunicators service integrator, Aybell, previously known as VisuMenu Inc.


Dr. Lavian has served as the CTO and principal investigator of CRadar.Ai, a company whose technology improves wireless radio signal phase noise purity by about 100x. The clean wireless radio frequency signal enables the use of a pioneering radar-based object detection system for autonomous vehicles. The startup’s high-accuracy imaging radar complements existing detection systems by sensing objects under poor weather and lighting conditions—fog, rain, snow, direct sun, total darkness—where conventional camera- and lidar-based autonomous driving systems often fail. CRadar.Ai was incubated in UC Berkeley’s startup accelerator, SkyDeck.


A part of UC Berkeley’s SkyDeck, Aybell is focused on creating a new way of connecting smartphone users to any company and service by digitizing interactive voice systems. As CEO, CTO, and a co-founder of Aybell, Dr. Lavian developed a way to transform mobile wireless devices and smartphones into visual menu systems that empower consumers to receive more rapid customer service using mobile applications, social media platforms, chatbots, and browsers.
Dr. Lavian led the design and implementation of the company’s service architecture and the voice menu search engine. Aybell is the branding and marketing name of VisuMenu Inc., advanced technologies, a cloud telecommunications system that provides network communications integration with a service provider’s telephone system.

VisuMenu Inc.

VisuMenu Inc. provides an innovative visual search engine for automated phone menus from mobile wireless devices and smartphones.
As co-founder and CTO of the company, Dr. Lavian led its software development and search engine design for IVR/PBX using Asterisk, SIP, and VoIP.
VisuMenu’s systems are deployed as a front-end mobile device interacting with Web services. Its back-end is based on cloud network communications, telecommunications, and cloud computing services via Amazon Web Services (AWS) and Google Cloud Platform (GCP). VisuMenu Inc. has since been re-branded as Aybell.
