Allen Z. Ren
Hi there! I'm a PhD student at Princeton, where I work with
Ani Majumdar on robotics. I am also a student researcher at Google DeepMind with Andy Zeng, and currently visiting Dorsa Sadigh's group at Stanford.
I design algorithms that enable robots and other agents to operate safely and robustly under diverse environment variations, thus building trust between humans and robots.
Currently I am particularly interested in:
(1) quantifying uncertainty of foundation-model-based modules (perception, planning, and control), thus triggering active knowledge acquisition when needed;
(2) robustfying policies trained with human demonstrations using diverse simulated scenarios for better generalization in diverse real environments.
Please reach out if you find them interesting!
