Brief Description of Research Interest:
 

Understanding the mechanistic orchestra behind neurodegenerative diseases, rare or orphan diseases at the molecular level, and providing therapeutic solutions or diagnostic insights is challenging. My keen interest in addressing key biological questions associated with those diseases has directed me to several research projects during my Ph.D. and postdoctoral tenure. A plethora of chemical tools, techniques, and concepts was used in the process of exploring those challenging biological questions. My interest spread over several research fields:

 1. Unfolding effects of Zn(II) perturbation on Zn(II)signaling pathways and labile Zn(II) dynamics in the mammalian cell cycle.

2. Functional analysis of site-specific PTM modifications on synuclein/tau proteins involved in Parkinson's /Alzheimer's disease.

 3. Developing novel small molecule drug/sensor for selective chelation/sensing of metal ions Cu(II) or Mn(II) to alleviate copper overload or to diagnose Mn overload diseases
