Asger Kjærulff Jensen

Asger Kjaerulff Jensen is a Danish mathematician working in quantitative energy trading. He holds a PhD in Mathematics from the University of Copenhagen (PhD defense June 2019) and a Master's degree in Mathematics from the same university, with an exchange term in Mathematics at the University of California, Berkeley. He represented Denmark at the International Mathematical Olympiad in 2007 and 2008 and was a participant at Baltic Way 2007 in Copenhagen. His published research spans quantum information theory and algebraic complexity: asymptotic majorization of probability distributions and the non-multiplicativity of border rank under the tensor product. Professionally he worked at Alipes ApS (quantitative/algorithmic trading, 2019-2023), co-founded ABN Energy ApS, was a Quantitative Analyst at the energy trading firm MFT Energy (2024-2025), and is now Senior Quantitative Researcher at QUENT ApS, a quantitative energy trading company.

• Quant employment verification: CONFIRMED. A dated quantitative-finance role plus a supported identity are both documented. MFT Energy publicly announced welcoming Asger Kjaerulff Jensen as a Quantitative Analyst (Sept 2024), a company-authored primary source; Danish company-registry records show him co-founder/director of ABN Energy ApS (2023-2025). Employer classification checked: Alipes ApS (alipes.dk) self-describes as automating the financial markets with models, ticks, latency and ML - a genuine algorithmic-trading firm; MFT Energy is a power/energy trading company; QUENT ApS (quent.dk) self-describes as 'Quantitative Energy Trading'. Identity supported: same name, Copenhagen location, mathematics PhD (University of Copenhagen), and a work history matching the MFT/ABN records. Caveat retained: the Alipes 'Quant' role (2019-11 to 2023-05) and the current QUENT Senior Quantitative Researcher role (2025-03-) rest on the LinkedIn/index lead rather than an independent primary page, so they are index-derived and not called primary-source confirmed here. The IMO 2007/2008 olympiad and the Nordea Markets student-assistant line are separate from the salaried quant roles.Sep 2024
• MFT Energy publicly announced welcoming Asger Kjaerulff Jensen to the team as a Quantitative Analyst, stating he holds a PhD in Mathematics - a company-authored primary source for the MFT Energy role.Sep 2024
• PhD in Mathematics from the University of Copenhagen; PhD defense event dated 2019-06-17, placing the doctorate completion around mid-2019.Jun 17, 2019
• QUENT ApS (quent.dk) self-describes as 'Quantitative Energy Trading', classifying the employer squarely in systematic energy trading rather than software or general 'quant' branding.2025
• INDEX-ONLY: ABN Energy ApS co-founder/director role is corroborated by Danish company registry (CVR) records; companydata.dk lists 4 corporate relationships including director of ABN Energy ApS (dissolved) and Asger Kjaerulff Holding ApS.2023
• INDEX-ONLY: Alipes ApS role as 'Quant' (2019-11 to 2023-05) rests on the LinkedIn/index enrichment lead, not independently confirmed on a primary page; Alipes is a Danish algorithmic trading firm, so the classification is consistent but the role itself is index-derived.Nov 2019
• Represented Denmark at the International Mathematical Olympiad in both 2007 and 2008 (IMO identity matches the stated olympiad identity); also listed among Baltic Way 2007 (Copenhagen) participants.2007
• Published research in quantum information theory: 'Asymptotic majorization of finite probability distributions' (arXiv 1808.05157, Aug 2018).Aug 15, 2018
• Co-authored 'Border rank is not multiplicative under the tensor product' (arXiv 1801.04852) with M. Christandl and F. Gesmundo, an algebraic-complexity result.Jan 15, 2018
• Borsen's job-news column records that Netcompany hired Asger Kjaerulff Jensen as a consultant after he graduated as a mathematician from the University of Copenhagen, describing the role as design, development and testing of business IT solutions - the earliest documented salaried role.2013
• Master's degree in Mathematics from the University of Copenhagen and an exchange term in Mathematics at UC Berkeley (index/CV-derived).2011
• The career path (Netcompany IT consultant 2013 -> PhD mathematics -> algorithmic trading at Alipes 2019) places all three quantitative-finance roles AFTER the mathematics doctorate, i.e. the quant career begins post-PhD rather than via the olympiad.2019
