Created the first genetically-engineered mouse model of ccRCC reproducing the genetics of the disease (Wang and Gu et al., PNAS, 2014).

Through the generation of mouse models, we demonstrated that BAP1 and PBRM1 function as tumor suppressors in ccRCC and are determinants of grade (Gu et al., Cancer Discovery, 2017).

Developed comprehensive tumorgraft platform closely mirroring human tumors that surpasses current conventional models in order to advance precision medicine. (Elias et al., Cell Rep, 2021)

Developed a biomarker assay for BAP1 that is being used in clinical practice (Pena-Llopis et al., Nat Genet, 2012 and Kapur et al., J Urol, 2014).

Determined that BAP1 is an independent predictor of ccRCC progression (Joseph et al., Cancer, 2014).

Determined that ccRCC can be divided into 4 molecular subtypes with different outcomes in patients and developed tests that can be applied to the clinic. (Joseph et al., J Urol, 2016).
