Magnetism And Spin Technologies Lab (MAST)

-exploring the unknown...

Magnetism and Spin Technologies (MAST) Lab focuses on exploring the unknown in the realm of nano-electronics and spintronics, especially for application in conventional non-volatile memory and advanced technologies such as neuromorphic and quantum technologies. We strive to be the 'mast' in the ship out to explore and challenge the boundaries of what we know and in the process develop advanced memory technologies. MAST lab is led by Dr. Tanmay Dutta.

Dr Tanmay is an engineer by training, teacher by passion, and researcher by profession. His interest lies in the fields of advanced memory and computing technologies. Working at the forefront/confluence of semiconductors, nanotechnology processes and material development he persistently strives to push the frontier of data storage and computing technologies. As an Assistant Professor, he balances his demanding research commitments with his true love - sparking curiosity and interest in young minds through his teaching and mentoring.
