Will Hwang Hi! I'm a Ph.D. candidate in Computer Science at Princeton University, where I am advised by Prof. Olga Russakovsky. My research interests include test-time training, efficient attention mechanisms such as linear attention, and long-context reasoning. I received my B.S. and M.S. from UChicago. |

MERLIN: Multi-State Linear Attention with Generalized Second-Order Routing
Hee Seung Hwang, Sanghyuk Chun, Xindi Wu, Olga Russakovsky, Zhiwei Deng preprint We route over multiple linear attention states using the mean and variance of each segment's key alignment with the query, improving long-context performance. |

ReFINE: Reinforced Fast Weights with Next-Sequence Prediction
Hee Seung Hwang*, Xindi Wu*, Sanghyuk Chun, Olga Russakovsky, Zhiwei Deng ICLR 2026 Workshop on Test-Time Updates, Best Paper Award NeurIPS 2026 Spotlight (1.3%) We present next-sequence prediction as a training objective for improving long-context modeling of fast weight architectures. |

COMPACT: COMPositional Atomic-to-Complex Visual Capability Tuning
Xindi Wu*, Hee Seung Hwang*, Polina Kirichenko, Olga Russakovsky ICLR, 2026 We present a compositional, complexity-aware VIT data recipe to improve visual reasoning in MLLMs. |

Learning a Doubly-Exponential Number of Concepts From Few Examples
Ilia Sucholutsky, Bonan Zhao, Hee Seung Hwang, Allison Chen, Olga Russakovsky, Tom Griffiths CogSci, 2025 We present a novel minimal paradigm that explores how efficiently people can simultaneously learn visual and symbolic concepts. |

Population-scale immune multiome atlas reveals regulatory disease mechanisms
Masahiro Kanai, Toni M Delorey, Jarno Honkanen, Rodosthenis S Rodosthenous, Julianna Juvila, Shane Murphy, Isabella Teixeira-Soldano, Hee Seung Hwang, Juha Karjalainen, Jussi Halonen, Georgia Panagiotaropoulou, Yuanxiang Zhang, Cristin McCabe, Eric Chen, Kosaku Nanki, Toshimi Yoshida, Kai Liu, Marla Glean, Nitya Mehrotra, Emily P Finan, Daniel Chafamo, Yixiao Zhu, Mikko Arvas, Sanni Ruotsalainen, Zhili Zheng, Yoshihiko Tomofuji, Daiki Tokuyasu, Shinichi Namba, Kyuto Sonehara, BioBank Japan Project, FinnGen, Yukinori Okada, Mary P Reeve, Mitja Kurki, Caroline BM Porter, Orr Ashenberg, Wei Zhou, Kimmo Pitkänen, Jukka Partanen, Aarno Palotie, Daniel B Graham, Mark J Daly, Ramnik J. Xavier Nature, 2026 We show that population-scale simultaneous profiling of chromatin accessibility and gene expression across immune cell types reveals multi-layered regulatory pathways connecting genetic variants to disease. |

Nuclear receptor coregulator NRIP1 R448G modulates T cell gut homing to control intestinal inflammation
Xiangjun Chen, Hee Seung Hwang, Bihua Li, Yanhua Zhao, Koushik Ghosh, Lei Deng, Elizabeth A. Creasey, Orr Ashenberg, Daniel B. Graham, Ramnik J. Xavier PNAS, 122, 2025 We show that NRIP1 R448G leads to intestinal inflammation by activating T cell gut homing and inflammatory cytokine production. |
