For people unfamiliar with quantitative trading, Patrick Chi’s career provides an interesting look at how mathematics, data analysis, technology, and financial markets can come together in a demanding professional environment. His background also shows how academic preparation and early experience can help build a career in highly competitive areas of finance.
This article explores Patrick Chi’s education, early professional experiences, career at Citadel Securities, trading background, and what makes his professional journey noteworthy.
Who Is Patrick Chi?
Patrick Chi is a U.S.-based financial professional associated with quantitative trading. Public professional information identifies him as a trader at Citadel Securities and places his professional base in New York. He studied applied mathematics at Columbia University, graduating in 2020.
His career is particularly interesting because it combines a strong mathematical education with hands-on experience at several well-known trading and financial firms.
Before entering a full-time role at Citadel Securities, Chi gained experience through research, quantitative trading, and trading internships. These opportunities exposed him to areas such as financial modeling, derivatives, market making, data analysis, and trading strategies.
Patrick Chi’s Educational Background
Education played an important role in Patrick Chi’s professional development. He attended Columbia University, where he studied applied mathematics. His university profile also identifies him as a C. Prescott Davis Scholar.
Applied mathematics can be particularly useful in quantitative finance because modern financial markets rely heavily on probability, statistics, mathematical modeling, optimization, and data analysis.
Rather than relying only on traditional financial knowledge, quantitative traders often use mathematical and statistical methods to understand market behavior and evaluate potential trading opportunities. Chi’s academic background therefore provided a strong foundation for the type of work he later pursued.
His university years also appear to have been closely connected to his growing interest in financial markets. Instead of waiting until after graduation to gain industry experience, he began developing practical skills through internships and early professional roles.
Patrick Chi’s Early Career
Patrick Chi’s career began with experiences outside his eventual full-time position at Citadel Securities.
Available professional records show that he worked as a research intern at Reach Advisors in 2016. He later gained research experience connected with Columbia University and worked as a quantitative trader at Blackmar Capital LLC from 2017 to 2018.
These early positions helped introduce him to data-driven analysis and quantitative methods.
His experience at Blackmar Capital was particularly relevant because quantitative trading involves using mathematical models, programming, statistics, and market data to make trading decisions. Such experience can provide a useful bridge between academic mathematics and practical finance.
By building experience before completing university, Chi was able to explore different parts of the financial industry and develop a clearer understanding of quantitative trading.
Patrick Chi and Optiver
In 2018, Patrick Chi joined Optiver as a trading intern. Optiver is known for its work in electronic trading and market making.
The internship gave Chi exposure to options theory and trading simulations. According to a published career profile, his work involved analyzing data and exploring approaches related to volatility and index options trading.
This type of experience can be valuable for an aspiring trader because options require an understanding of probability, pricing, volatility, risk, and market behavior.
The experience also helped connect his mathematical education with real financial-market problems. Instead of working only with theoretical models, he was able to see how quantitative concepts could be applied in a live trading environment.
Experience at Susquehanna International Group
The following year, Patrick Chi continued developing his trading background through an internship at Susquehanna International Group, commonly known as SIG.
His 2019 internship exposed him to additional areas of derivatives trading, financial modeling, and market analysis. Publicly available career information lists the role as a trading internship running from June to August 2019.
The combination of experience at firms such as Optiver and SIG gave Chi exposure to different approaches within proprietary trading.
For someone pursuing a career in quantitative finance, this type of experience can be especially useful. It provides opportunities to understand how traders evaluate markets, manage risk, analyze information, and make decisions under time pressure.
Patrick Chi’s Career at Citadel Securities
A major milestone in Patrick Chi’s career came in August 2020, when he joined Citadel Securities as a full-time trader after graduating from Columbia University.
Citadel Securities operates in electronic market making and financial markets, where technology, trading expertise, and quantitative analysis play major roles.
Chi has been publicly described as a trader working on the American Depositary Receipt desk. ADRs are securities that allow investors in the United States to gain exposure to shares of companies based outside the U.S.
In a published “day in the life” profile, Chi explained that the ADR desk makes markets in more than 3,000 ADRs and provides liquidity through buying and selling prices.
This role requires traders to pay close attention to international markets because the underlying securities can trade in their local markets outside regular U.S. trading hours.
What Does an ADR Trader Do?
American Depositary Receipts can seem complicated to people who are unfamiliar with financial markets.
An ADR represents an interest in a foreign company and trades in the United States. This allows U.S. investors to participate in international companies without directly purchasing the company’s shares on a foreign exchange.
For an ADR trader, monitoring international market activity can therefore be important. Price movements in a company’s home market can provide information about where its U.S.-listed ADR may trade.
Chi has described starting his workday by checking market information from overnight trading and reviewing how relevant international securities performed.
This illustrates how professional trading can involve continuous analysis rather than simply buying and selling stocks based on general market news.

His path demonstrates how an academic background in mathematics can translate into opportunities in financial technology and trading. It also highlights the importance of gaining practical experience before entering a full-time career.
Rather than following a traditional finance-only route, Chi built experience through research, quantitative trading, and internships at firms involved in market making and derivatives.
For students interested in quantitative finance, his career can serve as an example of how technical education and practical exposure can complement each other.
Patrick Chi’s Current Professional Profile
Public professional profiles continue to associate Patrick Chi with Citadel Securities and quantitative trading. His LinkedIn profile identifies Citadel Securities as his employer and Columbia University as his university.
