Hi Anmol,

To answer your question, I would say check published studies (original and reviews) on hyperlipidemia, obesity and lipids then compile the list of leading authors this will ensure that you atleast get top researchers in the field. These search can be done even on major online data base such as Scopus, Web of Science and Medline where you can be able to limit the research in accordance to name of author.

this research may help you

I agree with Kabelo Mokgalaboni.

Hi,

I am totally agree with @Kabelo.

You could search the field of study in pubmed or google scholar and also you could search the field of research interest of alumni of universities in the university websites.
