    Research Interests

    Johannes joined the group in April ’15. He studied pharmacy at the Julius-Maximilians-Universität Wuerzburg and obtained his PhD in the group of Prof. Dr. U. Holzgrabe (Institute for Pharmacy and Food Chemistry) at the University of Wuerzburg. During his PhD thesis, he was working on the synthesis and characterization of novel Ionic Liquids (IL) based on a poorly water soluble AMPA receptor antagonist against migraine.

    His present research is focused on:

    • Development of light-controlled phase transition systems for tuning solubility and skin penetration of drugs by cis-trans isomerization of the counterions.

    • Ionic Liquid approach to improve the dissolution rate and solubility of poorly water soluble drugs

    • Study of supersaturation effects and use in vivo

    • Synthesis of new counterions and salts of poorly water soluble drugs

    For his research he is using a broad range of different techniques:

    • Nuclear Magnetic Resonance Spectroscopy (NMR)

    • Infrared Spectroscopy (IR)

    • X-Ray Powder Diffraction (XRPD)

    • Differential Scanning Calorimetry (DSC)

    • Isothermal Titration Calorimetry (ITC)

    • High Performance Liquid Chromatography (HPLC)

    • SiriusT3 Instrument
