Welcome to ENCL
Challenging environmental problems at the atomic-, nano-, and molecular-scale
Research Interest
Our research is dedicated to unraveling the intricate processes governing
nanoparticles' pivotal roles in diverse environmental challenges. My specific
focus lies in investigating the characteristics and conduct of both natural
and engineered nanoparticles within ambient settings. I am particularly
intrigued by their interactions with biological entities, such as microbes
and the human respiratory system, as well as their impact on geochemical
and biochemical aspects, especially concerning hazardous elements like
radionuclides. Noteworthy research undertakings encompass nuclear waste
management, the aftermath of the Fukushima nuclear disaster, and the complexities
of atmospheric pollution
