## Research π¬

`Apr 2019-now`

**Postdoc @ QuTech Delft university of technology NL** π³π±

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

`Jul'17-Mar'19`

**Postdoc @ Caltech US** πΊπΈ

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** π¨π

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** π°π·

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

`Aug'10-Jun'12`

**Research assistant @ Chalmers, SE** πΈπͺ

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