Chaitanya Mitash

I am a Ph.D Candidate in the Computer Science department at Rutgers, co-advised by professors Abdeslam Boularias and Kostas Bekris . My research interests lie in the field of Robotics, Computer Vision and Machine Learning. Specifically, I am working on problems related to perception for Robotic Manipulation.
During my PhD, I did internships with Microsoft Hololens, Redmond, WA where I worked on semantic segmentation for mixed reality applications and at Amazon Robotics, North Reading, MA where I worked on task-driven perception for manipulation.
Before graduate school, I worked as a software engineer in the R&D divisions of Samsung Electronics and Tejas Networks in the embedded software domain. I received my B.E. degree in Computer Science from Birla Institute of Technology, Mesra in 2012.

That and There: Judging the Intent of Pointing Actions with Robotic Arms
Malihe Alikhani, Baber Khalid, Rahul Shome, Chaitanya Mitash, Kostas Bekris, Matthew Stone
AAAI Conference on Artificial Intelligence, 2020

Presents a set of interpretive principles for how a robotic arm can use pointing actions to communicate task information to people. The evaluation distinguishes two classes of pointing actions that arise in pick-and- place tasks: referential pointing (identifying objects) and locating pointing (identifying locations).
