Wikipedia
A quantitative analyst or, in financial jargon, a quant is a person who specializes in the application of mathematical and statistical methods – such as numerical or quantitative techniques – to financial and risk management problems. Similar work of industrial mathematics is done in most other modern industries, but the work is not always called quantitative analysis.
Although the original quantitative analysts were " sell side quants" from market maker firms, concerned with derivatives pricing and risk management, the meaning of the term has expanded over time to include those individuals involved in almost any application of mathematics in finance, including the buy side. Examples include statistical arbitrage, quantitative investment management, algorithmic trading, and electronic market making.
