Liu He

I am an applied scientist at Amazon Ring AI, working on enhancing MLLMs in-the-wild. I received my CS PhD at Purdue University, under Professor Daniel Aliaga. My research integrates cutting-edge techniques to solve interdisciplinary problems across CV/CG.

My passion is to well embed the physical world. Now my research focusing on synthetic data generation, advancing MLLM reasoning on visual tasks, and physcial-aware VideoGen as World Model.

I am open to collaborations and internships. Please feel free to contact me if we have common interest.

Hobbies

To be the best angler among CS PhDs :-)

I will be the angler of cover in 2025 Indiana State Fishing Guide, see my face in any retail outdoor stores :-)

Cool sites from Jon Barron's website. Thanks for Leonid Keselman's Jekyll template
