Das Sarma came to the United States from India as a physics graduate student in 1974 after finishing his secondary school (Hare School in Kolkata) and undergraduate education at Presidency College in Calcutta, India (now Presidency University in Kolkata) where he was born.

topological qubit in 2005,[5][6] which has led to experiments in building a fault-tolerant quantum computer based on two-dimensional semiconductor structures.

[7] In 2006 Das Sarma with Euyheon Hwang provided the basic theory for collective modes and dielectric response in graphene and related chiral two-dimensional materials.

[8][9] In 2011 Das Sarma and collaborators introduced a new class of lattice tight-binding flat-band systems with nontrivial Chern numbers which belongs to the universality class of continuum quantum Hall and fractional quantum Hall systems without any external magnetic fields.

In 2010, Das Sarma and collaborators, made a prediction that Majorana fermions will be found in condensed matter,[11] in particular, in semiconductor nanowires.
