I am an early career physicist with research experience in nuclear structure and reaction calculations (quantum many-body problem). I am proficient in Python, C++ and have experience with high-performance computing. I have foundational knowledge of Linear Algebra and have experience with research oriented analytical problem solving. 

While I have enjoyed defining questions and finding solutions in my research so far, moving forward I am interested in working on quantum algorithms for quantum computing applications or to use of artificial intelligence/machine learning in high-impact problems. I am currently open to work and looking for new roles.

Goal : Generate nuclear interactions more suited for computations of heavier nuclei like Pb208.
Method : Mapping non-trivial two- and three-nucleon forces onto finite oscillator basis.
 -> END-TO-END CODE DEVELOPMENT : Developed code for Chi-square optimization of two- and three-body parameters model parameters in Python, Solution for three-nucleon eigenvalue value problem (C++ and Python combined), Quadrature using Gaussian grids to perform basis transformation, Numerically expensive transformation from relative to lab coordinates on EC2 and Hyak (combination of Python and C++), Visualization of results using matplotlib.
-> Found analytical solutions using Quantum Angular momentum theory and properties of special functions
-> Learnt to set up ftp server to exchange large files with collaborators.
This role is an independent research position which requires defining research goals and initiating collaborations.
