Ridge, Ny

Gatekeeper for physics papers in the fields of statistical physics, complex networks, graph theory, social dynamics/demographics, fluid dynamics, complex fluids, biophysics, and computational physics. Reviewed scientific research and wrote extensively to authors as I shepherded their papers through the peer-review process.

The Data Incubator is an intensive 8 week fellowship that selects the best scientists and engineers with advanced degrees (< 3% acceptance rate) and prepares them to work as data scientists and quants. It identifies fellows who already have the 90% difficult-to-learn skills and equips them with the last 10%: the tools and technology stack that make them self-sufficient, productive contributors.

Analyzed the structure, properties, and dynamics of complex networks through extensive coding of programs in Python and C++ for numerical analysis and Monte-Carlo simulations. Developed thousands of lines of code to study statistical properties of large quantities of data, involving biological and sociological data.I have published several refereed papers in internationally recognized journals of general science and physics.

Invited as a summer researcher at the T-7 theoretical mathematics department. Mentored by Pieter Swart and Aric Hagberg, I studied statistical properties of bipartite social networks and helped developing the networkx package for network analysis in Python.
