lotfielhafi.com Profile

Title:Lotfi El Hafi Description:**Lotfi El Hafi, PhD**, is a **Research Associate Professor** at **Ritsumeikan University**, Japan, and the **President & Founder** of **Coarobo GK**, Japan. He received his **MScEng in Mechatronics** from the **Université catholique de Louvain (UCLouvain)**, Belgium, in 2013, and his **PhD in Engineering** from the **Nara Institute of Science and Technology (NAIST)**, Japan, in 2017. His master’s thesis contributed to **TICO** compression, now standardized as **JPEG XS**, for Ultra HD 4K/8K video distribution during an internship at **intoPIX SA**, Belgium, and later as a **Sales Engineer** while completing the **AWEX International Business & Management EXPLORT Program**. He then joined the **Robotics Laboratory** at **NAIST** as a recipient of the **MEXT Scholarship** in 2014. His PhD thesis proposed a novel eye-tracking method, *“**Simultaneous Tracking and Attention Recognition from Eyes (STARE)**,”* which leveraged deep learning to extract behaviors from scene images reflected in the eyes, earning him the *“**Best of IET and IBC 2016–2017**.”* He joined the **Ritsumeikan Global Innovation Research Organization (R-GIRO)** of **Ritsumeikan University**, Japan, for the *“International and Interdisciplinary Research Center for the **Next-Generation Artificial Intelligence and Semiotics (AI+Semiotics)**”* project as a **Senior Researcher** in 2017, later becoming **Research Assistant Professor** in 2019. His research activities included service robotics, AI, and system integration, with a particular interest in multimodal interaction in extended reality (XR). In this regard, he received 2 research awards from **JST CREST**: the *“**Best Award for Research Proposal Breaking Hagita-CREST Shell**: Visualization of Emergent Reality in Robotics for Future Harmonious Interaction”* and the *“**Best Award for Forecasting Research Proposal**: Toward Early Realization of Harmonious Human-Robot Interaction.”* He has also won numerous international robotics competition prizes, including the *“**1st Place**”* in the **Airbus Shopfloor Challenge** at **IEEE ICRA 2016**, the *“**Finalist Prize**”* in the **Amazon Robotics Challenge 2017**, the *“**NEDO Chairman’s Award for Excellence in World Robot Summit 2018**,”* the *“**SICE Award for WRS Future Convenience Store Challenge 2018**,”* the *“**METI Minister’s Award for Excellence in World Robot Summit 2020**,”* the *“**2nd Place Regional Prize in Eastern Asia + South Eastern Asia**”* in the **OpenCV AI Competition 2021**, and multiple *“**1st Places**”* in the **WRS Future Convenience Store Challenge** since 2018, including one at **IEEE/RSJ IROS 2022**. These contributions addressed both the technological and theoretical challenges of super-smart societies (**Society 5.0**), in collaboration with the **Robotics Hub** of **Panasonic Corporation**, Japan, where he has served as a **Research Advisor for Robotics Competitions** since 2019. There, he contributed to the development of **AMIS**, or *“**Autonomous Manipulation for Intelligence Services**,”* a human-centered robotic platform, also in collaboration with **NAIST**. His recognized achievements in competitions also led to his appointment as a **Specially Appointed Researcher of HSR Community** by **Toyota Motor Corporation**, Japan, from 2020 to 2022, during which he developed a containerized **Software Development Environment (SDE)** using cloud-first, open-source technologies to accelerate cross-institutional collaborative R&D. More than 20 institutions across Japan and the EU are known to have tested the **SDE**, with half adopting it for research. This endeavor earned him the inaugural *“**HSR Community Research Encouragement Award**”* from **RSJ** in 2022. He has held the position of **Research Associate Professor** at the **Research Organization of Science and Technology** of **Ritsumeikan University**, Japan, since 2023. His contributions to the development of large-scale cognitive architectures for the **JST CREST** project *“**Symbol Emergence in Robotics** for Future Human-Machine Collaboration”* and the **JST Moonshot R&D Program** *“The Realization of an **Avatar-Symbiotic Society** where Everyone Can Perform Active Roles without Constraint”* have led him to investigate the mechanisms of multimodal robot learning in XR. His recent work on probabilistic inference and contrastive learning for service robots received the *“**Best Paper Awards**”* at **IEEE/SICE SII 2023** and **IEEE IRC 2024**, respectively. Over the years, he has authored over 80 academic publications and holds an h-index of 13 on Google Scholar, with more than 450 citations. He has helped build a vibrant research environment at **Ritsumeikan University** through successful grant applications as a Principal Investigator, including a competitive **JSPS KAKENHI Grant-in-Aid for Early-Career Scientists** titled *“**Emergent Reality**: Knowledge Formation from Multimodal Learning through Human-Robot Interaction in Extended Reality,”* securing over 15 million JPY in cumulative internal and external funding. He also informally supervises graduate students and international interns in the **Emergent Systems Laboratory** at **Ritsumeikan University** and has formally supervised 4 international master’s theses with **UCLouvain**. He is an active member of **IEEE** (since 2015) and **RSJ** (since 2017), and a former member of **JSME** (2017–2022). He has peer-reviewed over 35 manuscripts for prestigious journals and conferences and served as **Associate Editor** for **IEEE RO-MAN 2021** and **Publicity Chair** for **IEEE/SICE SII 2026**. Finally, he is the **President & Founder** of **Coarobo GK**, Japan, which provides containerized **SDE** solutions for researchers and developers in the fields of service robotics and AI.
