Curriculum Vitae

I believe a career is built on meaningful impact rather than a long list of publications and metrics. This CV tells the story of my journey, my skills, and my purpose as a researcher.

Bio

Dr. Ahmad Jafar Arifi earned his Ph.D. in physics from Osaka University, Japan, in 2020, and his Bachelor’s degree from Universitas Indonesia in 2015. During his doctoral studies, he completed a six-month internship at the Japan Atomic Energy Agency (JAEA), gaining valuable exposure to experimental research environments. He then joined the Asia Pacific Center for Theoretical Physics (APCTP), South Korea, as a Young Scientist Training (YST) Fellow, and later worked at RIKEN, Japan, as a Special Postdoctoral Researcher (SPDR). Currently, he is a researcher at the Advanced Science Research Center (ASRC), JAEA. His research focuses on hadron spectroscopy, reactions, and structure, as well as hadrons in medium, employing various data-driven hadronic models and approaches.

Purpose

My purpose is to foster the growth of hadron physics communities in the Southeast Asian region. In physics, my primary objective is to build a broad understanding of hadron physics from multiple perspectives. Specifically, I aim to develop various quark models that explain the diverse properties of hadrons and nuclei, ultimately connecting this knowledge to QCD. To achieve this, I am dedicated to collaborating with new researchers and exploring different methods.

Education

I graduated from leading universities in Indonesia and Japan, where I developed a strong foundation in theoretical physics.

Student mentorships

I enjoy mentoring students and believe that every student is different. I encourage them to learn by themselves first, while offering help when needed.

• Co-supervising a couple of students from Indonesia and Thailand.
• Giving a career talk in International physics course (IPC) program 2025, Osaka University.
• Hosting a summer intern for a few weeks at Japan atomic energy agency.
