I grew up in South-West Russia and obtained an M.Sc. degree in experimental Condensed Matter Physics from the Southern Federal University in Rostov-on-Don.

In 2007 I moved to Berlin, Germany, in order to pursue a PhD in theoretical Molecular Physics with Prof. Bretislav Friedrich at the Fritz Haber Institute of the Max Planck Society. Our work was mainly concerned with a theoretical treatment of molecules in electric, magnetic and radiative fields, including field-dressed molecular collisions.

In 2011 I was awarded an ITAMP postdoctoral fellowship at Harvard University and moved to Cambridge MA in the United States. My research at ITAMP mostly focused on many-body physics of ultracold molecules, and dissipative state preparation in ultracold gases.

Since September 2014 I am an Assistant Professor at the recently established Institute of Science and Technology Austria (IST Austria). The main direction of my current research is understanding the physics of quantum impurities possessing orbital angular momentum. In addition, I'm interested in out-of-equilibrium behavior of cold atoms and molecules and using engineered dissipation as a tool to create novel few- and many-body states of matter.

Curriculum Vitae in pdf

I was born in Kunming, China — a small town however known as a tourist attraction. In 2007, I moved out hometown to Xi'an in the northwestern part of China, where I received higher education and M.Sc. degree. During those years, my major academic interest was in nonlinear optics theory, and one of my hobbies was to translate interesting scientific news and short stories to Chinese and publish them online.
Afterwards, I decided to keep heading towards northwest and moved to Austria to pursue a PhD in theoretical Quantum Physics with Prof. Dr. Mikhail Lemeshko. The main focus of my current research is on the strong-coupling limit of the angulon theory and self-localization transition.

Curriculum Vitae in pdf

I was born and grew up in a small town near Venice, Italy. I went on to study Physics at the University of Padua, were I completed my Bachelor's, Master’s and Ph.D. My Ph.D. thesis analyzed on the role of order parameter fluctuations in the BCS-BEC crossover and in high-Tc cuprate superconductors, under the supervision of Prof. L. Salasnich and Prof. P.A. Marchetti.

In September 2016 I moved to Vienna where I joined the group of Prof. Lemeshko at IST Austria. Here I plan on applying my experience in condensed matter and ultracold gases to the angulon theory.

Apart from physics, I like playing my guitars and skiing.

Curriculum Vitae in pdf

I grew up in Turkey and obtained my M.Sc. degree in Mathematical Physics from Middle East Technical University, Ankara, where I studied relativistic quantum information under the supervision of Prof. N.K. Pak.

At the end of 2010, I moved to Max Planck Institute for Nuclear Physics, Heidelberg, Germany for my doctoral study in the division of Theoretical Quantum Dynamics and Quantum Electrodynamics led by Prof. C. H. Keitel. The main subject of my Ph.D. research was the theoretical description of relativistic tunneling and tunneling time delay in a tunnel-ionization process. I completed my Ph.D. studies in early 2014 and stayed at the same place as a postdoc until April 2016.

Since May 2016, I'm an IST postdoctoral fellow at IST Austria in the Theoretical Atomic, Molecular, and Optical Physics group led by Prof. M. Lemeshko.

Curriculum Vitae in pdf

I was born, grew up, and finished early education in Medinipur (a small town near Kolkata) India.

In 2007, I completed M.Sc. in Applied Mathematics from Vidyasagar University, India. Then I moved to Indian Statistical Institute, Kolkata for doctoral study in Quantum Mechanics. In May 2013, I got Ph.D. after completing a theoretical project on several fundamental symmetries e.g. supersymmtery, PT symmetry of quantum mechanical systems and application of PT symmetry concept to optical systems with balanced gain and loss profiles.

From August 2013 to January 2015, I was a postdoc at Theoretical Nuclear and Quantum Physics department of University of Brussels (ULB), Belgium. There I was involved in constructing nucleon-nucleon interaction potential from experimental elastic scattering phase shifts data using an inverse scattering technique.

From May 2015, I am an IST Fellow and a member of theoretical atomic, molecular and optical physics group at Institute of Science and Technology (IST) Austria. I am investigating several aspects of many-body theory of ultracold quantum gases.

Curriculum Vitae in pdf

I grew up in Iran where I obtained my M.Sc. degree in atomic and molecular physics from Zanjan University, with a main focus on quantum optics.

Afterwards I started as a Ph.D. student in the experimental group of Prof. Helena Aksela at the University of Oulu in Finland. My Ph.D. thesis focused on understanding the structure of atoms and ions using Reyleigh scattering of light and radiation-assisted electron scattering.

Recently, I have been fascinated by the multidisciplinary taste of IST Austria and decided to join the group of Prof. Mikhail Lemeshko as an IST fellow postdoc. Here, my research deals with understanding of quantum rotation in the presence of a cold bosonic bath, aiming at explaining recent experimental data on molecules trapped in superfluid helium nanodroplets.
