Wen-Yi involves in the theoretical understanding of ferroic functional materials. She managed to publish more than 30 papers including Nature Communications, Advanced Materials, and npj series. During recent years, her research interest focuses on valleytronics. She has done a series of pioneering works regarding the mechanisms of inducing spontaneous valley polarization and its manipulation via external means. The main achievements include proposing the concept of ferrovalley and its extension to two-dimensional materials with orthorhombic lattice; presenting various ways to realize electrical control of valley polarization; introducing the concept of half-valley-metal; unveiling the potential existence of three-dimensional ferrovalley in ferroelectric organometal halide perovskites.Meanwhile, Wen-Yi has devoted herself to methodological developments. She jointly developed an optical code, named OPTICPACK, and the first-principles calculation tool MCFB (Materials Calculation Family Bucket). She individually developed IRREP - a group theory analysis code. She then succeeded in obtaining the Belgian FNRS (Fonds National de la Recherche Scientifique) grant, and Shanghai Pujiang Project.
