Dipesh Khanal received his PhD from The University of Sydney in 2019, specialising in applying advanced nano-spectroscopic techniques for evaluating the impact of nanoparticles on health. He is working as a research fellow and nano-characterisation theme leader at the Advanced Drug Delivery Group, The University of Sydney and an affiliate scholar at the University of Alabama at Birmingham. He has extensive experience in formulating pharmaceutical oral dosage forms and dry powder inhaler formulations for the treatment of life-threatening lung diseases. He has made significant contributions in applying cutting-edge nano-spectroscopic techniques like atomic force microscopy infrared spectroscopy (AFM-IR), Lorentz contact resonance spectroscopy (LCR), Optical photothermal infrared spectroscopy (O-PTIR) for evaluating nano-chemical, nano-mechanical domains of pharmaceutical aerosol formulations containing drug combinations, extracellular vesicles, nanoparticles, liposomes, and bacteriophages. His work on the characterization of extracellular vesicles using AFM IR was rewarded an outstanding publication award by the Royal Society of Chemistry. He has published more than 32 peer-reviewed papers within the field of nano-spectroscopy with 988 citations. He has served as an invited guest editor on the special issue on advanced nanoscopy for the characterisation of pharmaceuticals, biologics, and polymers in Advanced Drug Delivery Reviews). Currently, he is the review editor in Pulmonary Drug Delivery (specialty section of Frontiers in Drug Delivery, since 2022).
