Ivan Borsenco

Ivan Borsenco is a Moldovan-born mathematician and quantitative finance professional. He represented the Republic of Moldova at the International Mathematical Olympiad in 2003, 2004, 2005 and 2006, earning a bronze medal in 2005 and a gold medal in 2006 (28 points, rank 27). He studied Mathematics at MIT (B.S., Class of 2012), where he did undergraduate research with Prof. Vivek Farias (2011) and Prof. Steven Kleiman (2010), served as a TA/grader for MIT 18.445 Stochastic Processes (fall 2011), and completed a Finance Research Practicum with Bank of America (2011). After graduating he worked as a Quantitative Analyst at TIM Group (Global) in Boston (2012-2014), a firm operating a sell-side/buy-side trade-ideas network for equity salespeople and investment managers. He has remained active in mathematics education as a Senior Instructor with IDEA MATH and as the long-serving Editor of the Mathematical Reflections online journal.

Notes9

• Quant employment verification: UNRESOLVED. The indexed LinkedIn record lists 'Quantitative Analyst at TIM Group (Global)' for 2012-2014, and IDEA MATH independently lists his affiliation as TIM Group (Global); TIM Group's own site describes it as the world's largest independent trade ideas network serving sell-side brokers and buy-side hedge funds/asset managers - a financial-markets analytics business, not itself a quant hedge fund, market-maker or prop-trading firm. The role title and dates rest on the secondary LinkedIn index only; no primary TIM Group source naming him was found, so the quant-finance role cannot be fully confirmed.
• IMO official records show Ivan Borsenco competing for Republic of Moldova in 2003-2006, with a 2006 Gold Medal (28 points, rank 27, 94.8th percentile) and 2005 Bronze Medal - an independent primary source confirming the olympiad identity given in the brief.
• IDEA MATH lists 'Mr. Ivan Borsenco' as a Senior Instructor affiliated with TIM Group (Global) and MIT Class of 2012, with a Putnam Honorable Mention, an independent third-party page corroborating the MIT 2012 graduation and TIM Group affiliation.
• Bank of America 'Finance Research Practicum' (2011) is a structured finance-research program rather than a standard salaried internship: the indexed description states he developed a hedging strategy in a team against movements in PCA factors of LIBOR interest rates and priced caps, floors, swaps and swaptions - rates-derivatives quantitative work at a major bank.
• LinkedIn enrichment (index-only, MIT-era snapshot) lists Ivan Borsenco as 'Student at Massachusetts Institute of Technology' based in Cambridge, MA, with a BS in Mathematics (2008-2012) and past roles at TIM Group (Global), Bank of America, and MIT research; this is a single indexed profile, not independent primary-source confirmation.
• Served as a grader/TA for MIT 18.445 Stochastic Processes in fall 2011 (instructor Alberto De Sole), listed on the official MIT course sheet with public email [contact omitted] - a primary MIT source for the MIT affiliation, a public institutional email, and a probability/stochastic-processes course relevant to quantitative work.
• Long-serving Editor of the Mathematical Reflections online journal (2006-2009 per IDEA MATH) and a recurring problem proposer published as 'Ivan Borsenco, Massachusetts Institute of Technology, USA' (problems in 2007-2011 issues), showing sustained mathematical-community contribution after his own olympiad years.
• Gave the Metroplex Math Circle talk 'Exploring the World of Probability' on 19 January 2013, introduced as an MIT student and four-time IMO participant - a dated public speaking appearance.
• Listed as a Leader for the Republic of Moldova at EGMO 2026 on the EGMO people directory, indicating continued engagement with Moldovan national olympiad teams.
• TIM Group, the 2012-2014 employer, was acquired by Mergermarket Group on 24 May 2017; it trades as youDevise Ltd. and is headquartered in London - context on the employer's nature and later ownership.
