I recently finished my M.Sc. in Computer Science at Mila/University of Montreal/Robotics and Embodied AI Lab (REAL) under supervision of Prof. Liam Paull. I have also been fortunate to collaborate with Dr. Anqi Xu on my current and past research works. My research focus was to develop learning framework for solving semantic visual navigation task. Most recently, I just finished working on Lifelong Topological Visual Navigation. Prior to this, I spent considerable time researching the topic of adversarial attacks and defenses, where I published PAT (ICCV’19), MJSMA (MAIS’18), and a review paper (pre-print). I was also lucky to have been concretely introduced to the research world by working with Prof. Jeff Orchard in the Neurocognitive Computing Lab during my undergrad days. In general, I love working on various aspects on building robots, whether it is hardware or software - whatever makes a great robot great. I also enjoy presenting my work, so please feel free to let me know if you want to learn more about it!

CV / Blog / Paper summaries

When I am not doing research, I like to play music (mainly acoustic and electric guitars), make educational videos, read books, writing blog posts or paper summaries, and go for a hike. I also recently started to explore the creative side of 3D modelling and animation, here is my coffee + donut:

Note: the coffee + donut were created from scratch, and the textures of the wall + table + ground plane are from Poliigon.
