Research πŸ”¬

Apr'19-Apr'22 Postdoc @ QuTech Delft university of technology NL πŸ‡³πŸ‡±

I developed novel approaches based on machine learning to predict molecular dynamics and electronic structure properties of amorphous topological insulator materials. I supervised a multi-disciplinary team of condensed matter and quantum nanoscience researchers working on real-world applications of these materials.

Jul'17-Mar'19 Postdoc @ Caltech US πŸ‡ΊπŸ‡Έ

I successfully carried out an ambitious postdoctoral project funded by a personal Swiss NSF grant P2ELP2_175281 in collaboration with prof. Garnet Chan group from Caltech. I developed and implemented first of its kind computational many-body quantum chemistry framework to model two-dimensional crystalline materials. I demonstrated the power of the approach by computing low-energy spectral properties of two-dimensional molybdenum disulphide.

Oct'12-Apr'17 Doctoral assistant @ EPFL CH πŸ‡¨πŸ‡­

I discovered a new class of electronic band structure effects in two-dimensional transition metal dichalcogenides originating from the interplay of spin-orbit interactions and crystalline lattice symmetries. In collaboration with world-leading experimental groups, I was able to demonstrate these effects in real materials resulting in several high-impact publications.

Jun'12-Aug'12 Research assistant @ Seoul National University, KR πŸ‡°πŸ‡·

I studied electronic structure of edge states in models of overlapping topological graphene nanoribbons.

Aug'10-Jun'12 Research assistant @ Chalmers, SE πŸ‡ΈπŸ‡ͺ

I designed a concept of a nanoscale spin-mechanical single-electron transistor (SET).
