Early Life, Education & Academic Credentials
One of the more detailed profiles of Patrick Chi highlights that he studied Applied Mathematics at Columbia University, graduating around 2020.
His high school achievements also include being a semifinalist in the Intel Science Talent Search for a project involving tropical cyclones, which underscores his early aptitude in quantitative analysis and scientific research.
During his university years, Chi held research internships:
- At Reach Advisors, analyzing data to understand urban growth and constraints.
- At Columbia, working with weather / forecasting data and scripting tools to compare forecast models.
He also contributed academically by working as a grader / teaching assistant for mathematics education (via Art of Problem Solving), supporting students in calculus and related topics.
This blend of mathematics, data analytics, and academic engagement laid a strong foundation for his later work in quantitative trading.
Career Path & Professional Roles
Patrick Chi’s professional journey illustrates a progressive move into quantitative trading and market operations.
Early Quant & Internship Roles
- From 2017 to 2018, Chi worked as a Quantitative Trader at Blackmar Capital LLC, where he dealt with algorithmic strategies in digital assets and expanding market reach.
- In 2018, he held a summer internship at Optiver, where he focused on options theory, simulation trading, and volatility-based strategy development
- In 2019, he interned at Susquehanna International Group (SIG), further deepening his exposure to derivatives, trading models, and quantitative execution.
These roles collectively expanded his skill set across market microstructure, derivatives, data modeling, and algorithmic execution.
Role at Citadel Securities
In August 2020, Chi joined Citadel Securities as a Trader. At Citadel, he is reported to focus particularly on American Depositary Receipts (ADRs) and international equities, areas requiring a nuanced understanding of cross-border markets, regulation, and liquidity dynamics.

Skills, Strengths & Market Specialties
Patrick Chi’s profile suggests several key competencies and specializations:
- Quantitative & Analytical Skillset
His academic roots in applied mathematics and his early research experience equip him with strong capabilities in modeling, statistical analysis, and computational algorithms. - Algorithmic / System Trading
His early roles in algorithmic strategies (Blackmar, Optiver) and his current trading at Citadel imply fluency in devising, testing, and deploying trading systems under market conditions. - Cross-Market / ADR Focus
Working with ADRs and international equities demands knowledge of multiple jurisdictions, currency impacts, regulatory regimes, and market structure differences—an area where Chi is reportedly active. - Team-oriented & communicative
His internships, teaching roles, and research suggest he is comfortable collaborating across disciplines (engineering, researchers, traders) and communicating complex ideas. - Resilience & adaptability
Moving through varied roles, from research internships to high-stakes trading, requires adaptability to unpredictable market conditions and evolving strategies.
Public Presence & Professional Reputation
Though not a widely publicized figure in mainstream media, Patrick Chi does appear in several professional and niche contexts:
- LinkedIn Profile confirms his affiliation with Citadel Securities and lists educational and employment history.
- The Org / organizational charts include him in Citadel’s trading operations, verifying his position structurally.
- News / blog profiles talk about his career trajectory, emphasizing his success at a young age in a demanding field.
- Bloomberg profile lists a person named “Patrick Chi” as Chief Compliance Officer at Arxis Securities LLC—though it is uncertain whether that is the same individual.
- BrokerCheck shows a “Patrick Chi — Broker at BNP Paribas Securities Corp.” listing, including licensing and employment history details.
Because “Patrick Chi” is not an entirely unique name, cross-checking is essential to avoid conflating individuals. But in the trading / quant context, the profile from Citadel and the earlier internships align tightly.
Challenges, Risks & Career Insights
Navigating a high-performance trading career is far from easy. Here are some inherent challenges and insights drawn from Chi’s path:
High Pressure & Fast Paced Environment
Working at a place like Citadel Securities means decision-making must be fast, precise, and error-free. Latency, market volatility, and unpredictable events impose constant pressure.
Model / Algorithm Risk
As with all algorithmic trading, models may fail in black swan conditions, leading to losses. Maintaining robustness, stress-testing, risk controls, and fallback systems is critical.
Market & Regulatory Changes
Cross-border trading (ADRs, international equities) is subject to evolving regulation, currency risk, geopolitical events, and compliance burdens. Staying current is essential.
Attribution & Team Dynamics
In large firms, individual contributions may be less visible. Ensuring credit for your strategies, protecting intellectual property, and fostering team trust are part of career success.
Balancing Innovation and Stability
In quant trading, chasing novel ideas must be tempered by stability, risk control, and scalable frameworks.
That said, Chi’s trajectory demonstrates that combining rigorous training, diverse internships, and domain focus can lead to rewarding roles in top-tier firms.
Future Outlook & Prospects
Where might Patrick Chi go next? Based on his profile and path, here are plausible trajectories:
- Senior / Lead Trader / Portfolio Strategist
With further performance, Chi could oversee trading desks, lead strategic direction in ADRs, or manage multi-asset strategies. - Quant / Strategy Lead / Research Head
With his analytical roots, he may transition to lead quantitative research teams, developing new trading models or risk systems. - Multi-Market Expansion
He might expand into derivatives (options, futures), fixed income, or alternative asset classes, leveraging his cross-market skills. - Entrepreneurial / Startup Roles
Some traders with quant backgrounds spin off or build fintech, trading infrastructure, or quant analytics firms. - Mentorship / Teaching / Thought Leadership
Over time, he might present at conferences, mentor young quants, publish research or whitepapers, or teach. - Executive Leadership in Finance
As with many high-performing traders, moving toward executive roles (CIO, head of trading, strategy officer) in financial institutions is a possible long-term path.
If he continues to combine strong quantitative acumen, execution excellence, and strategic insight, his career could become a model path for the next generation of market professionals.
Conclusion
Patrick Chi represents a younger generation of quant traders who build from strong academic foundations, diversify experience across elite firms, and focus on high-impact niche markets. His path—from research internships, to algorithmic trading, to a trader role at Citadel Securities—shows how dedication, technical skill, and professional agility can lead to success in the competitive world of quantitative finance.
While he maintains a relatively low public profile, the footprints in organizational charts, professional bios, and career summaries suggest a rising figure in trading. For those watching the next wave of quant talent, Chi’s journey is instructive: diversify experience early, ground yourself in math and coding, seek exposure to multiple markets, and build both execution and risk consciousness.
