The marmoset is a highly vocal and highly social New World monkey with high reproductive rate. We are interested in the sound processing in the brain of marmosets, the vocal development and vocal communications of infant marmosets, as well as the establishment of marmoset models of human mental diseases. The current big challenge is the shortage of marmoset supply, which cannot meet the needs of scientific research and thus, impede the progress of marmoset studies.

Another challenge is the lack of experiments in maintaining a marmoset colony. This hand-rearing method significantly increases the survival rate of marmoset infants, and provides the opportunity to study the development of marmoset infants with a similar genetic backgrounds, but raised in different postnatal environments.
