  • Electrophysiology(membrane transport) & Epithelial linked disorder
  • Membrane trafficking and contact sites
  • Ca2+ and cAMP signaling
  • Tight junctions
  • Microbiome.
  • Assistant Professor - Department of Biochemistry, Central University of Rajasthan, Ajmer(2025 onwards)
  • Visiting Fellow - National Institute of Dental and Craniofacial Research(NIDCR) / National Institute of Health(NIH, MD, USA) (Spt'2019-April'2025) - Epithelial Signaling and Transport
  • Post-doctoral Fellow - Department of Pharmacology, University of Nevada, Reno School of Medicine(UNR, NV, USA) (Spt'2018-Aug'2019) - Smooth muscle E-C coupling.
  • Doctoral Fellow: Pathophysiology Division,  National Institute of Cholera and Enteric Diseases (ICMR-NICED, Kolkata, India) - Intestinal Ion Transport. 
  • M.Sc. in Biochemistry, B.Sc. in Physiology (Calcutta University, India)
    • Dr. Aoun is an trained electrophysiologist cum cell biologist. He is the first person in the field to discover the “pathophysiological role of TMEM16F or ANO6 (Cl- channel) in intestinal ion transport and physiological role of TMEM16A or ANO1( Cl- channel) in smooth muscle E-C coupling. He also worked on developing universal anti-diarrheal therapy.
    • He has a long-term interest in lipid regulation of membrane transport and trafficking. Now it's been evident that membrane contact sites like ER-PM or ER-Mitocondria contact sites are the hub of cellular signaling events(e.g, Ca2+ and cAMP signaling). These signaling nanodomains are highly dynamic architectures that modulate the channels and transporters' function during physiological and pathophysiological conditions. 
    • Current research interest is the role of lipid transporters in the orchestration of cAMP and Ca2+ signaling, regulation of membrane transport and trafficking.
