Work Experience |
Software Engineer at Parametros Trading (December 2012 - January 2015): Analyzed performance of our high-frequency stock trading system, measuring patterns in very noisy data and running simulations, and made improvements to the trading algorithm. Analysis of stock executions for a large hedge fund. Engineering work to improve robustness and scalability. Used Python, shell, and C++ on Linux. Software Engineer at eScription (now part of Nuance) (August 2006 - June 2011): Worked on computer assisted medical transcription (speech recognition and text formatting). Created algorithms and software to effectively use very large data amounts, and achieved 15% accuracy improvement. Worked with a large computer farm, participated in research conferences (ICASSP, Nuance Research Conference), and maintained and cleaned up legacy codebases. Used Python, Perl, shell, and C++ on Linux. Details: - Created a component to efficiently learn and apply millions of text mappings from billions of words of text. Implemented various techniques for best selection and application of the mappings. - Work involved full software lifecycle: Design, programming, testing (including rollout and production monitoring, and addressing customer support tickets), and software maintenance and bug fixing. - Contributed to various formatting components for finding headings, formatting numerics, numbered list recognition, adding punctuation, applying rule-based text transformations, etc. |

Mathematical Results |
Extended the language of set theory and provided semantics and axiomatization for higher order set theory; developed higher order set theory and demonstrated its close connections with large cardinal axioms (old paper and new paper). Proposed a solution to the Generalized Continuum Hypothesis (link1 and link2). Defined seemingly finitistic properties of complexity up to the second order arithmetic (link). Created a strong ordinal notation system (link), and wrote a Python program for ordinal comparison and arithmetic using the system (link). Defined a finite analogue of infinite models (link). Used probability to make conjectures in number theory about representability of numbers as sums of powers and primes (link). Proved an equivalence between WKL_{0} and a determinacy hypothesis (link). Paper "Determinacy and Fast Growing Sequences of Turing Degrees" (link). Paper "Space-Efficient Circuit Evaluation" (link). Defined constructive truth for arithmetic and analysis, and developed a corresponding constructive theory (link). |
