Jaakko Lehtinen ![](/sites/default/files/person/jaakko-lehtinen.jpg) Jaakko started out as a graphics programmer for Remedy Entertainment, an independent Helsinki, Finland based computer game studio, and contributed significantly to the look and feel of Max Payne 1 (2001), Max Payne 2 (2003) and Alan Wake (2010) through his work on rendering, modeling, and lighting technology. Jaakko obtained his Ph.D. from Helsinki University of Technology (now Aalto University School of Science and Technology) in 2007, after which he worked in research and teaching for two and a half years as a postdoctoral associate with Frédo Durand in the MIT graphics group. He joined NVIDIA Research in June 2010. Jaakko's interests span most areas of computer graphics, focusing on physically based rendering. ### Publications ### 2023 [A Hybrid Generator Architecture for Controllable Face Synthesis](/publication/2023-08_hybrid-generator-architecture-controllable-face-synthesis) Dann Mensah, Nam Hee Kim, [Miika Aittala](/person/miika-aittala), [Samuli Laine](/person/samuli-laine), [Jaakko Lehtinen](/person/jaakko-lehtinen) [SIGGRAPH 2023](https://s2023.siggraph.org/) ### 2021 [Appearance-Driven Automatic 3D Model Simplification](/publication/2021-04_appearance-driven-automatic-3d-model-simplification) [Jon Hasselgren](/person/jon-hasselgren), [Jacob Munkberg](/person/jacob-munkberg), [Jaakko Lehtinen](/person/jaakko-lehtinen), [Miika Aittala](/person/miika-aittala), [Samuli Laine](/person/samuli-laine) EGSR 2021 ### 2020 [Training Generative Adversarial Networks with Limited Data](/publication/2020-12_training-generative-adversarial-networks-limited-data) [Tero Karras](/person/tero-karras), [Miika Aittala](/person/miika-aittala), [Janne Hellsten](/person/janne-hellsten), [Samuli Laine](/person/samuli-laine), [Jaakko Lehtinen](/person/jaakko-lehtinen), [Timo Aila](/person/timo-aila) [NeurIPS 2020](https://nips.cc/Conferences/2020) [Modular Primitives for High-Performance Differentiable Rendering](/index.php/publication/2020-11_modular-primitives-high-performance-differentiable-rendering) [Samuli Laine](/index.php/person/samuli-laine), [Janne Hellsten](/index.php/person/janne-hellsten), [Tero Karras](/index.php/person/tero-karras), Yeongho Seol, [Jaakko Lehtinen](/index.php/person/jaakko-lehtinen), [Timo Aila](/index.php/person/timo-aila) [ACM Transactions on Graphics 39(6) (Proc.
