I specialize in improving educational practices for multilingual immigrant children. My research is guided by the view of language as a resource for effectively teaching immigrant learners. I have conducted research on the validity and fairness of assessments administered to these learners and their teachers and investigated ways to provide opportunities for immigrant children to demonstrate their funds of knowledge in assessments and classrooms. As the lead author of influential papers, I have argued that teachers need to develop specialized knowledge base and set of skills in order for their teaching to attend to the translanguaging practices of the multilingual learners. Current research project examines the development of formative simulated classroom environments for educating science teachers to teach immigrant children. Over a decade now, I have taught various culturally and linguistically diverse learner groups in higher education and foreign/second contexts.
