      <description>&lt;p&gt;IRIS 연구실 석박통합과정 박주홍 연구원은 현재 미국 Duke University의 CEI Group (Prof. Yiran Chen)에서 Visiting Scholar로 연구를 수행하고 있습니다.&lt;/p&gt;
&lt;p&gt;박주홍 연구원의 연구는 이종 인메모리 컴퓨팅 환경에서 거대 언어 모델(LLM)을 효율적으로 실행하기 위한 하드웨어–소프트웨어 최적화에 초점을 두고 있습니다. 특히 DRAM-PIM(Processing-in-Memory)과 CIM(Compute-in-Memory)과 같은 신흥 메모리 중심 아키텍처를 대상으로, 압축 기법의 적용, 이종 환경에서의 워크로드 스케줄링, 컴파일러 기법을 포함한 Near-Data Processing(NDP) 기반 공동 최적화 전략을 탐구하고 있습니다.&lt;/p&gt;
&lt;p&gt;이를 통해 연산·메모리·전력 제약이 큰 환경에서도 실용적으로 적용 가능한 자원 효율적 LLM 서빙 경로를 제시하고 있으며, 앞으로도 CEI Group과의 협력을 통해 LLM 시스템 최적화와 메모리 지향 아키텍처의 융합을 지속적으로 확장해 나갈 예정입니다.&lt;/p&gt;
&lt;p&gt;Juhong Park, a Combined M.S./Ph.D. student in our lab, is currently serving as a Visiting Scholar at Duke University’s CEI Group (Prof. Yiran Chen).&lt;/p&gt;
&lt;p&gt;Her research focuses on hardware–software co-optimization for efficient large language model (LLM) execution in heterogeneous in-memory computing environments. In particular, she explores joint optimization strategies in Near-Data Processing (NDP) systems, targeting emerging memory-centric architectures such as DRAM-PIM (Processing-in-Memory) and CIM (Compute-in-Memory). Her work includes the efficient application of compression techniques, workload scheduling across heterogeneous systems, and compiler-level optimization methods.&lt;/p&gt;
&lt;p&gt;Through this research, she aims to propose resource-efficient LLM serving pathways that remain practical under compute, memory, and power constraints. We look forward to her continued efforts to advance the convergence of LLM system optimization and memory-centric architectures in collaboration with the CEI Group.&lt;/p&gt;
