He completed training in sleep medicine at the Albert Einstein College of Medicine and joined the University of Pittsburgh School of Medicine as associate professor of pediatrics.

Muzumdar is interested in the obstructive sleep apnea in pediatrics and his work has demonstrated the changes in autonomic function in children caused by sleep apnea. He is also interested in identification of obstructive sleep apnea in children with tracheostomies prior to decannulation of the tracheostomy. He was a member of the group that defined the effects of adenotonsillectomy in children with obstructive sleep apnea in a large multicenter study (the ChAt study). In his role as program director of pediatric pulmonology, he is interested in the effects of the COVID-19 epidemic on training, trainees and faculty.
