Research Interests / Professional Overview

We are intrigued to investigate the impact of metabolites that function as non-autonomous signals in pathophysiological conditions like 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 are seeking a motivated and enthusiastic candidate to join our group. The ideal candidates should be recent master's or PhD graduates in related biomedical research field. Experience in animal models and biochemistry techniques is preferred.

The position is available immediately and remains open until filled.
