Professional Experience :

Current Position :  

September 2024 onwards

Academy Research Fellow, Department of Applied Physics, Aalto University :

I am awarded the Academy Research Fellowship by the Research Council of Finland. My 4-year research plan aims at creating tunable platforms to realize designer unconventional superconductivity, which can be easily integrated into practical devices. Also, this project aims at systematic understanding of their microscopic behavior.

Previous work experiences:

February 2023- September 2024:

Research Fellow, Department of Applied Physics, Aalto University:

My current research interest involves exploring the heavy fermionic phase diagram by the creation of artificial heavy fermion vdW heterostructures, aiming to drive the system into the quantum critical point and unconventional superconducting phase. I am also aiming at creating high temperature artificial topological superconductivity using manipulation of magnetic atoms on superconducting substrates, as well as developing methodology involving Josephson tunnelling spectroscopy to characterise these unconventional superconducting phases. I am employing state of the art molecular beam epitaxy for the sample growth and 300 millikelvin, 11 Tesla scanning tunnelling microscope to measure local electronic properties with atomic-scale resolution.

February 2019- February 2023:

Postdoctoral researcher, Department of Applied Physics, Aalto University:

My research interest included 2-dimensional (2D) quantum materials. Examples of these systems includes monolayer transition metal dichalcogenides (such as NbSe2, TaS2, VSe2, FeSe etc.), monolayer transition metal halides (such as CrBr3, NiI2 etc). These systems exhibit exotic quantum phenomena such as unconventional superconductivity, ferromagnetism, mott insulator and predicted quantum spin liquid phases. Also, combining these 2D materials with seemingly competing order using vdW epitaxy, we have been able to artificially create quantum states of matter such as topological superconductivity and heavy fermionic system.

7 February 2017- 8 February 2019:

Postdoctoral research associate, Department of Physics, University of Illinois at Urbana Champaign, USA: During my first postdoctoral stint, I designed and assembled a molecular beam epitaxy set up for the growth of transition metal selenides, one 2 Kelvin Scanning Tunnelling Microscope (STM) (Manufacturer: UNISOKU), and one tabletop 5 K STM (Manufacturer: UNISOKU). I subsequently investigated the growth and electronic properties of epitaxial monolayer ferromagnet VSe2 and monolayer superconductor NbSe2.

25 July 2011- 31 August 2016:

Research Scholar (Graduate student), Tata Institute of Fundamental Research, Mumbai, India:

The central aim of my Ph.D. thesis was studying the nature of order-disorder transition of vortex lattice in a type II superconductor in the presence of quenched random disorder (Co-intercalated bulk NbSe2) by real space imaging using STM. I was also involved in determining scaling of the order parameter distribution and emergence of superconductivity in disordered NbN. I was also involved in design and assembly of homemade STM.
