He was a Chaired Professor of International Banking and Finance, Associate Dean, Chairman of the Faculty Evaluation Committee, and Director of the PhD program at INSEAD, the international business school in France and Singapore. He led the INSEAD’s PhD program as it placed its first graduates as assistant professors at top universities such as Harvard, the University of Chicago, Stanford, Yale, and UCLA; and at leading European business schools.

In between INSEAD and Columbia, Lars Tyge Nielsen held positions at Goldman Sachs in counterparty credit risk, at Morgan Stanley as head of model reviews, and at Platinum Grove Asset Management as head of risk management. He has been a Chair Professor of Nankai University, and he has held adjunct and visiting appointments at the Copenhagen Business School, the Courant Institute of Mathematical Sciences at New York University, the Department of Finance at New York University, the University of Copenhagen, and Columbia University. He has been President of the European Finance Association and has served on a number of conference program committees as well as various professorship appointment committees at Scandinavian universities and business schools. He has been a Research Professor (“Super-professor”) at the University of Copenhagen. Early on, he was an Assistant/Associate Professor of Economics and Finance at UT Austin.

Lars Tyge Nielsen has a PhD in economics from Harvard and master’s degrees in mathematics and economics from the University of Copenhagen. He received the University of Copenhagen’s gold medal in economics for 1979 – one of only five such medals awarded between 1940 and 1980. He also received the University’s gold medal in mathematics for 1980 (received in 1985) – one of only 13 such medals awarded between 1940 and 1980.
