Research Interests / Professional Overview

We are intrigued to investigate the impact of metabolites that function as non-autonomous signals in pathophysiological conditions such as aging and diabetes. Recently, we found that succinate, a TCA cycle metabolite was significantly elevated in mammalian and bacteria exposed to high glucose. Our recent paper in Nature Communications demonstrates that succinate enhances osteoclastogenesis through its receptor Sucnr1 in vitro and in vivo. We will reveal a novel mechanism of succinate and its G-protein coupled receptor (SUCNR1) in osteoclastogenesis, inflammaging and aging-related bone loss.

We have postodotoral positions open, please see below for details:

We are seeking a well-trained researcher with excellent work ethic and the ability to join a NIH-funded group and work on projects to discover the mechanisms that regulate the interaction between microbiome and immune cells under normal and diseased conditions. The primary project is based on our recent finding on succinate stimulated osteoclastogenesis under diabetic condition in Nature Communications ( The applicant is expected to work independently as well as in collaboration with other group members to complete projects in a timely manner.

The candidate should have a PhD in Cell Biology, Biomedical Sciences, or related field. Hands-on experience in molecular biology and cell culture (primary cell culture and differentiation) are required. Familiarity with flow cytometry and FACS cell sorter is highly desirable. Priority will be given to candidates with strong oral communications and writing skills, as evidenced by a strong publication record. In addition to manuscripts, the candidate will be expected to participate in writing animal protocols and research proposals. Competitive salary and benefits commensurate with the candidate's qualifications.

Interested applicants should submit a brief statement of research interests, a CV, and three references to Dr. Xin Li at The position is available immediately (Nov. 2017 until filled).

Preferred specific skills:

  • RNA-seq
  • PCR/qPCR
  • Cell culture
  • Western blot
  • Immunocytochemistry/Immunohistochemistry
  • Surgery in small animals
  • Flow cytometry
  • Bone marrow transplant
  • Genetic modification (transfection/transduction)
