My Resume

About Me

I am a PhD candidate in the computer science department at University of Southern California (USC). I am working with Professor Kevin Knight at the Information Sciences Institute (ISI). Prior to joining ISI, I got my Bachelor and Masters degree from Sharif University of Technology.

My research interests are in the fields of Natural Language Processing, Machine Learning and Artificial Intelligence. Recently, I have been working on machine translation for low resource languages where we extend automatic translation technology to hundreds of languages that are not covered by the current machine translation systems.

Projects


project name

AMR: Abstract Meaning Representation

The AMR Bank is a set of English sentences paired with simple, readable semantic representations. We hope that it will spur new research in natural language understanding, generation, and translation. Please visit the AMR page for details.

project name

3D Human Pose Estimation

In this project we propose methods to infer a full-body 3D pose of humans from a single image captured by a typical camera. Human pose estimation plays a key role in many applications such as video surveillance systems, human computer interaction, interactive games, and special effects industry.

project name

Video Error Concealment

Transmission of image and video signals over error-prone channels is susceptible to bit erasures and packet losses. In this project we use correctly received areas of the images to recover those areas corrupted by transmission errors.
