Curriculum vitae
Carlos Arocha, FSA, SCR
I am a Zurich-based consulting actuary, educator, and founder of Arocha & Associates. My work combines actuarial depth with climate risk, data science, and model governance to help insurers and other organizations turn complex technical questions into decisions that can be explained, governed, and implemented.
I work across insurance and reinsurance, drawing on international experience in pricing, reserving, financial reporting, solvency, quantitative risk modeling, machine learning, and professional education.
Professional profile
Four connected areas of practice
Technical depth, joined around the decision.
Pricing, reserving & risk
Technical pricing, reserving, reinsurance retention, portfolio economics, IFRS 17, Solvency II, SST, model validation, actuarial sign-off, and underwriting and management decision support.
Modern analytical methods
GLMs, ensemble methods, neural networks, hybrid actuarial/ML approaches, explainability, validation, governance, and deployment of practical analytical applications.
Knowledge transfer
University teaching, professional education, mentoring, research, writing, and speaking focused on making complex actuarial and quantitative methods understandable and usable.
Current practice
Arocha & Associates GmbH
Founder & Managing Partner · Zurich · 2011–present
I founded Arocha & Associates in Zurich to provide independent, senior-led actuarial and quantitative advice. I lead engagements directly and, where needed, work with specialist collaborators while maintaining clear accountability for the assignment.
The practice spans insurance and reinsurance, climate risk, and data science, with work across pricing, reserving, financial reporting, solvency, model validation, quantitative risk analysis, governance, and professional training.
