Zakaria Ziadi ザカリア ズィアディ
zakaria.ziadi [at]

I completed my Ph.D. in electronic and electrical engineering from the University of the Ryukyus in 2015. My research in the Nanoparticle by Design Unit in OIST was focused on the understanding of gas phase synthesized nanoparticle effect on semiconducting nanowires based micro devices. My current research interest focuses on the effect of nanocarbon materials on graphene-based micro/nano devices and their applicability in gas sensing, bio sensing and optoelectronics.


Postdoctoral Researchers / 博士研究員   

Xiushang Xu 許 修尚 (OIST Postdoctoral Scholar)
xiushang.xu [at]

I received my bachelor’s degree (2013) in Applied Chemistry from the University of Shandong. I obtained my Ph.D. from Changchun Institute of Applied Chemistry under the supervision of Prof. Lixiang Wang in January 2019. My dissertation was on the design, synthesis and optoelectronic properties of novel light-emitting and electron transport materials based on spirobisilafluorenes as building blocks. My current research interest focuses on the bottom-up synthesis of novel nanocarbon materials with atomically-precise structures for optoelectronic devices and bioimaging.

Goudappagouda (JSPS Postdoctoral Fellow)

I obtained my M.Sc. (Chemistry) from Kuvempu University, Karnataka. I received my Ph.D. in Chemical Science under the guidance of Dr. Santhosh Babu Sukumaran from CSIR-National Chemical Laboratory, Pune, India, in 2020. My Ph.D. focused on the design and synthesis of donor/ acceptor organic small molecules for lighting and light-harvesting applications. I also studied the charge carrier mobility and conductivity of donor-acceptor co-assemblies. My current research work is focused on the design and synthesis of nanographenes with zigzag and armchair edges for optoelectronic and photonic applications.

Jingyun Tan (OIST Postdoctoral Scholar)

I studied applied chemistry and organic chemistry during my bachelor and master stages, respectively. Then in Jan 2020, I received my doctoral degree from University of Macau with a concentration in biomedical sciences. Organic molecule synthesis is the foundation of my research. Pursuing a suitable application for useful material is always the goal. My studies cover linear and nonlinear optics, chiroptics, bioimaging and sensing. My current research interests focus on the synthesis of polycyclic aromatic hydrocarbons (PAHs) and the exploration of their applications in the optical/biological fields.

Hao Zhao 趙 浩​ (JSPS Postdoctoral Fellow)
hao.zhao [at]

I studied chemistry at Shaanxi Normal University (China) and obtained my bachelor’s degree in 2015. I received my PhD in organic chemistry from the Institute of Chemistry, Chinese Academy of Sciences in 2020. My current research interest mainly focuses on the synthesis of new multifunctional carbon nanomaterials for biosensing, bioimaging and biomedical therapeutics.


Hiroki Hanayama 花山 博紀 (JSPS Postdoctoral Fellow)

I received my Ph. D. degree from The University of Tokyo under the supervision of Prof. Eiichi Nakamura in March 2021. During my Ph. D, I focused on transmission electron microscopic (TEM) analysis of organic molecules, especially in the supramolecular chemistry of cyclodextrins. My current research work focuses on the development of a structural characterization method for nanocarbon materials using TEM.



N. Maximilian Bojanowski (JSPS Postdoctoral Fellow)
niklas.bojanowski [at]

I studied chemistry and received my doctorate in 2021 from the University of Heidelberg on conjugated polymers for sensing applications and organic electronics. During my first postdoctoral tenure at the Karlsruhe Institute of Technology, I developed new photoinitiations for 3D laser nanoprinting. In November 2022, I joined OIST as a JSPS and Humboldt fellow. My current research aims to investigate the bottom-up synthesis of nanocarbon materials and the modulation of their optoelectronic properties.


Clément Delacou ドゥラク クレマン (Interdisciplinary Postdoctoral Fellow)​
clement.delacou [at]

In 2014, I graduated a Master of Engineering in Technical Textiles and Advanced Materials from ENSAIT (École Nationale Supérieure des Arts et Industries Textiles) in Roubaix (France). I obtained my PhD in The University of Tokyo in 2019 after working mostly on organic and perovskite solar cells using carbon nanotubes or graphene electrodes, supervised by Prof. Yutaka Matsuo and Prof. Shigeo Maruyama. From 2020 to 2021, I did a postdoctoral research about nanofluidic and ion transport in devices using one individual carbon nanotube (IONESCO Project) in The University of Montpellier (France). In 2022, I did a second postdoctoral research on atomic force microscopy of graphene in The University of Genoa (Italy). I am now working at OIST on applications of nanographenes in solar cells with two units: Organic and Carbon Nanomaterials Unit (Prof. Akimitsu Narita) & Energy Materials and Surface Sciences Unit (Prof. Yabing Qi).
