If interested in research positions, contact me at MariaRez2010@gmail.com. We have positions in different states and specialties. Some are in the top 5 universities in the US. Provide some brief info about yourself, your visa status, your USMLE scores, what (sub)specialty, which state, when you want to start and for how long. In the subject, please mention what you’re looking for. For example: “Endocrine research in Chicago.”
We do have paid positions too, but you need to have had a prior experience in lab research. Otherwise, it's unlikely you can get a paid position. Also remember the visa limitation (you can't get paid on all visas). Some positions are non-paid initially, but may become paid with time as you gain experience and prove yourself to be productive.
