About Len

I am an enthusiastic and resourceful chemist with 25 years of experience after Ph.D. in chemistry. I have 20+ scientific publications in the well-known international journals. I have worked in the leading life sciences and molecular diagnostic companies for 20 years. I have used my chemistry and scientific knowledge to build instruments, develop reagents and diagnostic tests. I have utilized my skills in both academic and industrial settings and can provide a better chemical perspective to students based on my years of experience. Please check out my short profile on Linkedin if you like.

To learn chemistry, one has to understand the atomic and molecular principles. I like to use practical examples in teaching chemistry that would help in grasping the subject matter easily. Chemistry or any other subject must be learned in a way one can apply that knowledge in real life. We can learn about any chemical easily if we know how we feel about the existence of air even when we have not seen the air. A sound understanding of basic principles will make any student feel that the chemistry subject is not difficult but actually it is fun to learn it.

Chemistry

I have BS, MS, and PhD degrees in Chemistry with 25 years of experience doing chemistry research. I also have 21 publications in highly reputed international scientific journals. I have expertise in actually characterizing small and large molecules. I have used a large number of chromatographic and spectroscopic techniques in my 25 years of research. Examples: HPLC, ion-exchange, gel-filtration and affinity chromatography. I also have a vast experience with NMR, Mass, IR, UV-Vis, fluorescence, and circular dichroism spectroscopy.

Organic Chemistry

I have an M.S. degree in Organic Chemistry. I have synthesized many organic compounds myself. I have synthesized porphyrins, benzene sulfonamides, peptides. I have also characterized all these organic compounds by standard organic chemistry methods such as UV-Vis, IR, NMR and Mass spectrometry. I have studied and worked with organic compounds for more than 10 years.
