Each October, Marex celebrates Ada Lovelace Day – a moment to recognise women in STEM whose innovation, curiosity, and courage are shaping the future of our industry.
This year, our Ada Lovelace Series spotlights two remarkable women whose paths into STEM reflect the same visionary spirit Ada Lovelace embodied nearly two centuries ago: Snigdha Aggarwal and Qianyu Sun.
Snigdha Aggarwal — Curiosity. Analysis. Action.
For Snigdha Aggarwal, curiosity has always been a compass. As a Funds, AMC and QIS Trader, her work sits at the intersection of mathematics, data science, and financial engineering. Each day, she transforms complex data into insight, pricing and managing multi-billion-dollar derivative portfolios while designing scalable infrastructure to support innovation across markets.
Snigdha’s fascination with STEM began early, nurtured by a love of logic, patterns, and problem-solving. Growing up in a small town in India, she was surrounded by tradition but empowered by parents who encouraged her curiosity without limits. The story of astronaut Kalpana Chawla, the first woman of Indian origin in space, became a lasting source of inspiration. Chawla’s legacy taught her that curiosity is not just an asset – it’s a superpower.
From engineering studies at IIT Delhi to risk management in Mumbai and trading in London, Snigdha’s career has been a masterclass in adaptability. Markets shift, technologies evolve, and organisations transform – but curiosity, perseverance, and empathy remain constants.
To her, success lies not only in technical mastery but in listening, collaborating, and leading with intention.
Mentorship, she says, has been a cornerstone of that growth. Whether guiding 850 first-year undergraduates through a redesigned orientation at IIT Delhi or mentoring junior colleagues at Marex, Snigdha views mentorship as a cycle of empowerment. It’s how talent is nurtured, voices are amplified, and barriers are broken for the next generation of women in STEM.
For Snigdha, Ada Lovelace Day is more than a celebration – it’s a call to action. It’s a reminder that innovation starts with bold questions and that every woman’s voice belongs at the table.
Qianyu Sun — Progress, Not Perfection
As a Structured Product Operations Analyst, Qianyu Sun ensures the seamless operation of Marex’s OTC Derivatives and Structured Notes business. Her work blends precision with innovation – building processes, controls, and automation that keep complex systems running smoothly.
Her journey into STEM began through friendship. Surrounded by peers thriving in technical fields, Qianyu’s curiosity about programming grew into passion. That spark led her to pursue formal training during her master’s studies, setting her on a path toward a career defined by learning and evolution.
At Marex, Qianyu takes pride in being part of a team that drives innovation with an entrepreneurial mindset, developing lifecycle management solutions and implementing strategic initiatives through flexible, automated systems. Building controls from the ground up isn’t easy, but for her, it’s deeply rewarding to see ideas turn into impact.
Her outlook on growth is simple yet profound: embrace change, keep learning, and trust that every bit of effort adds up, even when progress feels slow. Ada Lovelace Day, for Qianyu, serves as a reminder to stay curious, support one another, and recognise that every contribution matters.
Carrying the Legacy Forward
Snigdha and Qianyu’s stories are a testament to the many paths that lead to STEM, each shaped by curiosity, courage, and the willingness to learn. They remind us that progress doesn’t come from perfection but from persistence and purpose.
At Marex, we’re proud to celebrate the women who continue to push boundaries, build with intent, and inspire others to follow in their footsteps – just as Ada Lovelace once did.
