Summary

A highly motivated quantitative analyst with comprehensive mathematical modeling and implementation skills and in-depth knowledge of quantitative finance including Term Structure Models, Financial Derivatives, Risk Management, Probability Theory and Stochastic Calculus; seeking a position as a Quantitative Analyst or related where these skills and knowledge will add greater value.

Work History

Quantitative Analyst

Citigroup Inc.
  • Studied all types of computational errors such as discretization, truncation and interpolation errors and controlled errors within the limits given.
  • Found the most appropriate values of parameters including dampening factor implemented in the CGMY model.
  • Priced financial derivatives in the CGMY model using numerical approaches such as the trapezoidal and Simpson's rules.
  • Applied the Fast Fourier Transform (FFT) to simultaneously price a large number of contracts with the desired accuracy.
  • Developed a new methodology to effectively price the contracts using Hilbert Transform approach which shows substantial improvements in pricing accuracy and computational cost.
  • Assisted managers on trade approvals and finance on price verification methodologies.

Intern as Quantitative Researcher

Investment Technology Group Inc.
  • Assisted in building proprietary options pricing models which show improvements in terms of pricing accuracy and computing efficiency.
  • Assisted in developing algorithms for company's Multi-Asset Execution Management Systems (MAEMS).
  • Implemented various financial derivative models in the quantitative analysis of private equity investments using C++ programming.
  • Created formal modeling of risk, return and trading cost profiles for equities and other firm-wide assets classes.

Credit Risk Model Validation Analyst

CITIC Securities Co. Ltd.
  • Extensively tested the risk models including sensitivity analysis, extreme value testing, uncertainty analysis, backtesting, and benchmarking to challenge the models effectively.
  • Evaluated the model use appropriateness in the context of CCAR/DFAST.
  • Found inappropriate use of equity replication model in the counterparty credit risk exposure project, and debugged it.
  • Wrote comprehensive independent validation reports explaining the analysis performed and their results.

Research Projects

University Of Illinois At Urbana-Champaign
  • Term structure models: applied Hull-White one-factor model and LIBOR market model (LMM) to price and calibrate a range of interest rate products such as European swaption, multi-look trigger swap, caption, Bermudan swaption, constant maturity swap (CMS), and a real world CMS derivative; results show that the LMM in general leads to better estimation of derivative prices than the Hull-White one-factor model.
  • Optimization: conducted Markowitz mean-variance analysis using Black-Litterman returns using 10 years of data on S&P 500 stocks and applied the Black-Litterman model to reconstruct portfolio allocation and studied the sensitivity of portfolio.
  • Risk management: developed and implemented the dynamic conditional correlation (DCC) models to forecast the future correlations among S&P 500 stocks and optimized related portfolios, sponsored by Busey Bank.
  • Monte Carlo Simulation: applied random tree method to price path-dependent options with high computational efficiency by creating a MATLAB application to perform Monte Carlo simulations.
