Levon Khachatryan


I am a senior machine learning researcher specializing in computer vision, with expertise in generative modeling, segmentation and classical computer vision. Currently driving innovation at Picsart, where I contribute to groundbreaking projects in image and video domains. Additionally, I share my knowledge and expertise as a Computer Vision Lecturer in the Applied Statistics and Data Science Master’s program at Yerevan State University, while also supervising master’s theses for students.

My current research focuses on Generative AI in Computer Vision, particularly I am recently working on:

  • Image/Video Generation
  • Controllable Image/Video Editing
