I have done my Master of philosophy in the field of chemistry of natural products my major was (Isolation, Identification and Bioevaluation of natural products from medicinal plant) from Quaid-i-Azam University Islamabad, Pakistan, ranked as No. 1 university of Pakistan. I got scholarships and a laptop from the government of Pakistan on the basis of good academic performance I am proficient in identification and screening of bioactive phytochemicals using HPLC-MS & MS/MS techniques. My M.phil research work consisted of identification of phytoconstituents by using HPLC MS/MS profiling, 80% of the compounds from the crude extract has been identified without the need for purification, which makes it a useful tool for screening and dereplication. Isolation and structure elucidation of secondary metabolites from Medicago Polymorpha for drug discovery using a combination of MS and NMR techniques. Identification of the metabolites involves the spectroscopic techniques using NMR, MS, GCMS, UV-VIS, and classical wet chemical techniques. Troubleshoot and maintenance of analytical instruments as needed. Structure elucidation of novel natural products from Medicago Polymorpha by using NMR spectroscopy, LCMS, isolation and purification of compounds by using silica gel chromatography. I have experience of teaching at university of Wah. I have taught different courses such as inorganic chemistry, biochemistry and general chemistry to BS 4th and BS 2nd. I have taught these courses in funny and creative manner. Several people think that chemistry is rough and tough subject but i want to say no its not like that because no subject becomes difficult when teacher makes it easy. All those who are facing difficulty in studying chemistry should come to me and see how i am making chemistry easy. thanks.
