Alice Cheambe (née Motanga) is a graduate from Technische Universität Berlin (TUB) where she studied Computer Science. During her study she majored on Computer-Aided Systems and Open Communication Systems. She carried out research on her Diploma Thesis - Session Mobility Support Architecture for Seamless Multimedia Service Delivery within Home Area Networks at Fraunhofer Institute FOKUS as a student and in July 2007 joined the Next Generation Networks Infrastructure (NGNI) team as a researcher.


In the early phase as a researcher at NGNI, Alice was involved in numerous industry projects with major telecommunications providers in Europe, South East Asia, Japan and South Africa with the focus on deploying IP Multimedia Subsystems (IMS), developing prototype service APIs and frameworks for IMS clients and carrying out ETSI Interoperability tests for IMS. 

With the emergence of new Web technologies, another area of research has been in converging web domain services such as WebRTC with IMS services. 

After 2.5 years of parental leave, she has returned to the NGNI team with a new research focus - . Alice is currently working on two EU projects - NUBOMEDIA and reTHINK

NUBOMEDIA objective is to design and implement a a Real Time Communication (RTC) and multimedia processing architecture that uses emerging Network Function Virtualization (NFV) and Software Defined Networks (SDN) to provide enabling cloud technologies. It provides a Platform-as-a-Service (PaaS) strategy which hides the complexity of the infrastructure thereby abstracting services for provisioning, scaling, QoS and network management.

reTHINK objective is to design and prototype a new, non-telecom centric, but Web-centric P2P Service Architecture enabling dynamic trusted relationships among distributed applications called Hyperlinked Entities (“Hyperties”) that support use-cases beyond commoditized telephony such as contextual and social communications, M2M/IoT and content oriented services. 

Alice also supports and supervises student projects and Diploma thesis. She is regularly guiding several students complete their university projects as well as their Diploma/Master Thesis.
