Jingwen Cai
I’m a Ph.D. student in the Foundations of Language Processing group at Umeå University.
My research brings together reinforcement learning with online advertising as well as finite-string transductions, with a focus on creating more effective and optimized solutions.
My work also involves a great deal of user studies and human–computer interaction, aiming to bridge the gap between theory and practice in real-world scenarios.

More About Me
I enjoy building Lego sets and 3D metal models!
I love riding scooters and exploring trails --- though to be honest, it’s more walking than hiking, since steep climbs aren’t really my thing :p.
My fridge is basically a gallery. I’m obsessed with collecting magnets!
I can play the zither and hold a Level 9 Certificate of Qualification. Want to hear what it sounds like? Click here!
