I'm a postdoc in machine learning / computational biology.
Prior to that, I worked in computational manybody physics
and engineering:
2013  2015  PhD in Theo. Physics,^{P12P18}
Theo. Nanophysics Group,
LMU Munich,
visiting
Columbia U
(spring semester 2015)

2012  2013  PhD in Electr. Eng.,^{P8P11}
Materials Simulation Group,
Bosch Research, Stuttgart (defended 2014 at
U ErlangenNuremberg)

2011  2012  Research Associate,^{P6,P7}
Center for Electronic Correlations and Magnetism,
U Augsburg

2006  2011  Studies of Physics,^{P1P5}
U Augsburg (MSc 2011, BSc 2009),
visiting
ENS Paris (fall semester 2010)
and
Georgetown U
(spring semester 2010)

I aim at applying concepts from computational manybody physics to highdimensional machinelearning problems in computational biology. I'm also interested in (and have been trained on) the following topics
> 
Solving dynamical meanfield theory (DMFT)
using matrix product states
(MPS=Tensor Trains~DMRG)
^{P12P18,O6}


> 
Nonequilibrium physics of strongly correlated manybody systems
^{P16,P4P1}


> 
Exact solution of quantum Rabi model
^{P7,P6}


>  Phenomenology of superconductivity: supercurrent through grain boundaries ^{P5 }  
> 
Statistical physics
^{T1,P3}


> 
Diffusionreaction: chemistry of defects and impurities in silicon
^{O5,P11P8}


> 
Photovoltaics
^{O5,P11P8}
