I'm a computer scientist, specializing in digital geometry processing and the use of machine learning for data-driven solutions to geometric problems. My research focuses on richer tools for geometric design, particularly by novice and casual users, and on related problems in shape synthesis and editing. This research is driven by a more abstract interest in shape understanding at both the structural and semantic levels: Why is a model of a chair not one of a chicken? What distinguishes a well-designed chair from a badly designed one? How can one build a better chair?
Some major themes in my work have been assembly-based (compositional) shape synthesis, shape detailization, weakly-supervised and multi-view shape analysis, and attribute-driven shape design. Of late, I am also particularly interested in 2D vector graphics and image vectorization. My research combines ideas from graphics, vision, machine learning and HCI, and I have published in all of these areas. I have also significantly contributed to real-world software, including Adobe Illustrator, Project Neo, Adobe Substance 3D Modeler, and the late Adobe (formerly Mixamo) Fuse (for which I was the architect and chief developer).I'm a Senior Research Scientist at Adobe Research, New York. I received the Indian National Science Academy's Medal for Young Scientists, 2022, while at Adobe Research, Bangalore. I was an Assistant Professor (full time 2015-17, on leave 2017-22) in the department of Computer Science and Engineering at IIT Bombay, where I held an Institute Chair and received the Early Research Achiever Award. Earlier, I spent a year as a lecturer at Cornell University. Even earlier, I was a postdoc at Princeton University, working with Tom Funkhouser. I received my PhD from Stanford University in 2011, supervised by Vladlen Koltun.

Note: Adobe Research offers summer internships to outstanding students. Please follow the official procedure, don't send me email. If you're interested in working with me, mention my name in your application. I do not take on students without a strong background in graphics/vision/machine learning (typically at least 2 out of 3).

I wrote and maintain Thea, a freely available, BSD-licensed library of C++ classes for computer graphics, primarily for 3D geometry processing (not to be confused with the concurrently developed Thea Render, which I am not connected with). It is the core library I use for nearly all my research projects, and it is also the core library for Adobe Fuse, which I originally authored.
