Alexandros Lattas
I am a researcher with interests in Generative AI and Digital Humans. Currently working as a Research Scientist at Google. Previously, I was a Research Scientist at Huawei's Noah's Ark Lab, and at our Imperial College lab spin-off startup Facesoft.
I obtained my PhD at Imperial College London, with Stefanos Zafeiriou and Abhijeet Ghosh as my advisors. Two of my PhD projects were commercialized in spin-off startups, Generative Adversarial Networks for facial reconstruction with Facesoft, and practical facial capturing systems with Lumirithmic.
