Giovanni Caforio, Laurie Glimcher, Jill O'Donnell-Tormey, Dr. Giovanni Coforio, Dr. Lori Glimcher, Jamie

Immunotherapy has emerged as a transformative cancer treatment by harnessing the patient's immune system to target mutated cells through checkpoint blockade, offering a personalized alternative to the non-specific toxicity of traditional chemotherapy. Clinical trials in melanoma and lung cancer have demonstrated that this approach yields response rates exceeding 60% and has nearly eliminated the need for first-line chemotherapy in these malignancies. Looking ahead, the field aims to expand these outcomes by addressing patient non-responsiveness through strategies that personalize therapy based on unique tumor genetic profiles.

Why OCaml

Approximately a decade ago, Jane Street adopted OCaml as its primary functional programming language to secure C-like performance and rigorous type safety while maintaining development conciseness. This strategic choice serves as a filtering mechanism for hiring, attracting highly motivated engineers through a specialized one-month training program that results in a consolidated, high-performing workforce. Although the firm faces ecosystem limitations compared to mainstream languages, the implementation of a single language across its multi-billion-dollar systems enables significant code reuse and shifts the priority from empirical testing to the universal guarantees of static type checking.

Ron Minsky

Ron Minsky, a technical leader at Jane Street Capital, presented a comprehensive case for prioritizing code correctness and maintainability through strict OCaml design principles that leverage the type system to enforce data invariants and ensure pattern match exhaustiveness. The lecture outlined specific architectural strategies, including mandatory interfaces, uniform naming conventions, and a "reader-over-writer" philosophy, which collectively minimize cognitive load and prevent silent failures in high-stakes financial systems. Additionally, the speaker addressed immediate course logistics by extending the Moogle project description deadline and recommending simple list-based implementations to avoid unnecessary debugging complexity.

Caml Trading

Carl Curry, Ron Minsky

Jane Street Capital, a proprietary trading firm operating in four global cities, transitioned its primary development stack to the functional programming language OCaml to satisfy critical demands for absolute correctness, high performance, and code maintainability. This adoption enables the firm's 35 core developers to leverage OCaml's powerful type system and algebraic data types for static exhaustiveness checks, ensuring the rigorous standards required to process billions of dollars in daily equity trades without error. While the language presents challenges in ecosystem maturity, the firm has actively mitigated these gaps through its Jane Street Summer Project and achieved superior hiring outcomes by attracting engineers skilled in functional paradigms.

Seven Implementations of Incremental

Incremental is an internal OCaml library that efficiently refreshes large computations by modeling logic as a dependency graph, allowing localized updates when only small data subsets change. Through eight iterative development phases, the team resolved critical academic limitations regarding garbage collection and dynamic graph restructuring, culminating in a production-ready V8 implementation that achieved a threefold speedup using generalized algebraic data types. This technology successfully transformed a slow trading system frontend into the suite's fastest application and is now being explored for reactive JavaScript compilation and efficient functional data structure diffing.
