I am a GenAI Researcher at HeyGen where I focus on research and applications of generative video models for content creation. I obtained my PhD in Computer Graphics at CTU in Prague under the supervision of prof. Daniel Sýkora. I hold BSc and MSc degrees in Computer Science from the same university. My entire research career has been revolving around generating realistically looking content given certain conditions. During my PhD I focused on research into style transfer -- generating realistically looking paintings and animated movies. I was fortunate to do two internships at Adobe Research, one at Snap Research, and one at Samsung Research America; which resulted in 8 publications and winning the Best in Show Award at Real-Time Live at SIGGRAPH 2020. Upon completing my PhD, I joined NEON, Samsung Research America as a senior research scientist where I spent more than 2 years focusing my research into computer vision techniques to generate virtual humans with a particular emphasis on photorealism, resulting in 9 patents and CVPR publication. Then I joined Drip Artificial as a founding research scientist to lead the research efforts into generative AI, diffusion models, synthesizing stylized videos given a text description, and propagating edits through the video.
Diffusion and generative models to synthesize stylized videos given a text description; including style transfer, video synthesis, propagating edits through the video sequence, implicit neural video representations.
