Jayanth (Jay) Kannan is VP of Software Engineering and leads Lumirthmic’s software engineering team. Jayanth’s expertise is in building market solutions for computer graphics, AR, VR, machine learning, and AI. Prior to joining Lumirithmic, Jayanth founded his own game development company before moving on to work in the software industry – most notably working on several popular games ranging from first person shooters to vehicle simulations using their own proprietary game engine.

After his stint with game development, he went on to work in the software industry by getting involved in the rapidly growing mobile applications space. He has worked with various companies to build apps for verticals ranging from banking, travel, government, line of business to mental health. Together, Jayanth has more than 16 years of experience bringing software and bespoke applications to market, as well as providing mentorship to many startups.

Jayanth holds an MSc in AI (Knowledge Systems) from the University of Sussex.

Luca Filipi is a Senior Software Architect at Lumirithmic. His expertise is in computer graphics, with a particular focus on real-time graphics and virtual production. He is experienced in the use of game engines and other adjacent technologies, such as VR and AR, particularly in the context of developing real-time tools and workflows for film production.

Prior to joining Lumirithmic, Luca worked in the visual effects industry, as he held roles on the virtual production R&D teams at MPC and Foundry, where he contributed to the development of software solutions that were used on the sets of several major motion pictures. His film credits include titles such as The Lion King (2019) and The One and Only Ivan (2020).

Luca holds master’s degrees in Physics and Computer Science from Imperial College London. He also has previous research experience in material acquisition and appearance modeling, having published a paper as a co-author on polarization-based reflectometry.

Gilles Rainer is a Senior Research Scientist at Lumirithmic. His expertise is in material scanning, appearance modeling, and neural rendering. Throughout his research, his focus has been on photo-realistic digitization of real-world assets in combination with modern machine learning/deep learning techniques.

During his PhD, Gilles worked on scanning and rendering textiles with complex appearance, in collaboration with Change of Paradigm Ltd., a designer fashion startup. Gilles also worked on efficient neural rendering algorithms for real-time rendering, both during a Post-Doc at INRIA Sophia Antipolis and during an internship at the Global R&D Lab of Playstation/SIE London, which resulted in several patents.

Gilles holds a PhD and an MSc from University College London, as well as an Engineering Diploma from Telecom ParisTech, one of France’s top engineering schools. His research has been published in leading Computer Graphics journals and conferences.

Lewis Bridgeman is Research Engineer at Lumirithmic. His expertise is in computer vision and graphics, with a specialization in parametric modeling of human shape and appearance from video for VR, 3D human pose estimation and tracking, and the application of computer vision to sports.

Prior to joining Lumirithmic, Lewis worked on the research and development of groundbreaking new virtual reality projects including Derren Brown’s Ghost Train at Thorpe Park and Galactica at Alton Towers.

Lewis holds an MEng degree from the University of Surrey in Electronic Engineering with audio-visual systems.

Claudio Guarnera is Senior Consultant at Lumirithmic. His expertise is in computer graphics, computer vision, color appearance, and applied perception, with experience both in academia and industry.

Claudio is also a Lecturer at the University of York, a Senior Researcher at NTNU in Norway and a Guest Researcher at Justus-Liebig-Universität Gießen in Germany.

Claudio Guarnera began his research career in computer graphics as a visiting researcher in the Graphics Lab of the USC Institute for Creative Technologies, followed by postdoctoral research experience at the University of Milan-Bicocca in Italy and at Loughborough University in UK, working on color and material appearance.

Ekin is a research engineer at Lumirithmic and is also pursuing a PhD at Imperial College London. They have a BSc in Physics and Astrophysics from University of Toronto and a MSc in Physics from Imperial College. They have also completed a prestigious Young Graduate Traineeship at the European Space Agency at ESTEC in the Netherlands, where they developed AI/ML approaches for state-based optimal control feedback of dynamical systems.

Currently, under the supervision of Dr. Abhijeet Ghosh, their research projects are at the intersection of differentiable realistic rendering, machine learning and physics. At Lumirithmic, they are working on implementing the algorithms and captures systems in conjunction with the software and research engineering teams.

Michael Bronstein is DeepMind Professor of AI at the University of Oxford and Head of Graph Learning Research at Twitter. He was previously a professor at Imperial College London and held visiting appointments at Stanford, MIT, and Harvard, and has also been affiliated with three Institutes for Advanced Study (at TUM as a Rudolf Diesel Fellow (2017-2019), at Harvard as a Radcliffe fellow (2017-2018), and at Princeton as a short-time scholar (2020)).
