Lecturer and researcher with extensive experience in theoretical quantum computation for analysing complex problems, drawing insights from data at hand and enhancing decision making. University topper in Bachelor’s physics by securing 98% marks. Recipient of prestigious Victoria India doctoral scholar.
Dealt with delayed choice experiments involving qubits, NOON states, quantum states, etc.
Involved in a project that determines entanglement by making use of propagator method.
Developed a hybrid algorithm, whilst at Swinburne University for solving stochastic differential equations projected onto manifolds occur mainly in engineering, optimization theory, nanotechnology, physics, chemistry and biology which eliminated the bugs in the earlier projection algorithms.
Solved complex mathematical problems by developing models with alternative solutions, discussing findings and optimizing designs with latest information.
Created mathematical or statistical phenomena models for analysis or computational simulation use.
Avoided project delays and a diminished reputation for Swinburne by accepting additional responsibilities to learn new phase space techniques and fulfil the role of researcher to successfully deliver a difficult project.
Successfully developed and delivered Majorana Phase space methods by learning Grassmann algebra which was ‘above and beyond’ my usual accountabilities and published a paper based on it in a highly reputed journal.
Successfully published 4 research papers in highly reputed journals.
