Modeling and Optimisation of the Purification of an Intermediate Drug Substance by Counter Current Extraction (CCE)  Developed a model of a countercurrent extraction column using Aspen Plus and Aspen Custom Modeler to optimize purification process of drug substance  Carried out laboratory works like titration, extraction and preparing starting materials  Worked with analytical methods like HPLC and GC  Worked with programs like Chromeleon and SciFinder

Thermodynamic Investigations for New Precipitation and Fractionation Strategies for Polysulfones  Thermodynamic experiments for the precipitation of polymer in polymer/ solvent/ anti-solvent mixtures  Optimization of precipitation technique to separate oligomers from polymer product and to obtain narrow molecular weight distribution polymer product  Thermodynamic modeling of polymer precipitation  Worked with analytical methods like HPLC und GPC(Gel Permeation Chromatography)

Metal surface treatment  Prepared new products (metal surface treatment agents) by varying starting materials and their concentration  Tested the advantages of new products in terms of stability, foaming, solvent consumption and residual contamination  Worked with analytical methods like titrimetric analysis, carbon analysis and photometric analysis  Visited Corus in Netherland (Customer) to observe the application of the developed product
