Prof. Hao Yan


Assistant Professor (Tenure-track)

My research interests include: 1) stable isotope kinetics in calcite growth, diffusion, evaporation, oxidation of reduced sulfur, etc.; 2) non-mass-dependent fractionation of oxygen and sulfur isotopes in nature; 3) Water cycling on the Moon; 4) carbon cycle in inland water bodies; 5) development of new method for isotope analysis.
