Giorgio Ferrari is a Full Professor of Mathematical Finance at the Center for Mathematical Economics (IMW), Bielefeld University. He obtained his Ph.D. in Mathematics for Economic and Financial Applications from the University of Rome “La Sapienza” in 2012. He then joined IMW as a postdoctoral researcher (2012–2016), later serving as Junior Professor (2016-2017) and Associate Professor (2017-2023). He is currently Director of the Bielefeld Graduate School in Theoretical Sciences (BGTS), Associate Editor of the journal Mathematics and Financial Economics, and co-chair of the international scientific network AMaMeF.
His research interests lie in stochastic control and game theory, and their applications to economics and finance. Particular attention is devoted to dynamic stochastic optimization problems and (mean-field) games involving singular controls and stopping rules, as well as to the analysis of the corresponding free-boundary problems. His research has been published in leading journals in the field, including SIAM Journal on Control and Optimization, Mathematics of Operations Research, Operations Research, The Annals of Applied Probability, Finance and Stochastics, and Mathematical Finance.
Giorgio Ferrari is Principal Investigator of Project C4 in the Collaborative Research Center 1283, a Principal Investigator in the Research Training Group 2865, and a member of Bielefeld University’s Focus Areas QUAMU and ESyMath.

Before joining the University of Bielefeld in May 2021, Peter Limbach was the CFR Junior-Professor of Investments at the University of Cologne. He holds a German Diploma (equivalent to MSc) in economics from the University of Bonn and a PhD in finance from the Karlsruhe Institute of Technology. Peter is a research fellow of the Centre for Financial Research (CFR), Cologne, as well as a member of the Hamburg Financial Research Center (HFRC). His research papers have been published in leading scientific journals in accounting and finance and have repeatedly been accepted for presentation at top academic conferences, such as the Western Finance Association annual meetings and the AAA FARS Mid-Year meetings. Peter organizes one of Europe’s leading virtual research seminars in accounting and finance. Also, since 2021, Peter has held the position of vice chairman of the scientific commission Banking and Finance of the German Academic Association for Business Research (VHB), and since 2022, he has served as co-editor of Management Review Quarterly.
Prof. Peter Limbach is an expert on various topics in applied econometrics, corporate finance and governance as well as corporate sustainability. Via the German Academic Association for Business Research (VHB), he offers the course “Empirical Corporate Sustainability Research” for PhDs across the German-speaking countries. Peter is also very passionate about topics of business valuation.

Prof. Dr. Frank Riedel is a Full Professor of Mathematics and Economics at Bielefeld University and Director of the Center for Mathematical Economics (IMW). His research focuses on mathematical finance, decision-making under uncertainty, game theory, and general equilibrium theory. He studied mathematics and philosophy in Freiburg and Berlin, received his Ph.D. and Habilitation from Humboldt University Berlin, and has held academic positions at Humboldt University, the University of Bonn, and visiting appointments at institutions including Stanford University, UC Berkeley, and Princeton University. Since 2007, he has been a professor at Bielefeld University, where he plays a leading role in research on uncertainty, risk, and strategic interaction in economic systems.
Frank Riedel’s research expertise lies in the mathematical and theoretical foundations of economics, with a particular focus on decision-making under uncertainty, mathematical finance, and game theory. His work integrates tools from probability theory, stochastic analysis, and economic theory to study financial markets, risk measurement, general equilibrium under uncertainty, and strategic interaction among economic agents. He is especially known for contributions to dynamic risk measures, Knightian uncertainty, model ambiguity, and equilibrium analysis, bridging rigorous mathematical methods with core economic questions about uncertainty, incentives, and market behavior.
His research papers have been published in top journals in Economics (Econometrica, Review of Economic Studies), Finance (Finance and Stochastics, Mathematical Finance), and Applied Mathematics (Annals of Applied Probability, Stochastic Processes and their Applications).
Frank Riedel is speaker of the Research Training Group 2865 "Coping with Uncertainty in Dynamic Economie" and co-speaker of the Collaborative Research Center 1283 "Taming uncertainty and profiting from randomness and low regularity in analysis, stochastics and their applications". He has obtained numerous grants at the national and international level, leading to collaborations with top schools including the Paris School of Economics, Princeton University, and Kyoto University.

Maren Diane Schmeck has been a Professor of Actuarial Sciences at the Center for Mathematical Economics (IMW), Bielefeld University, since 2023. Her research interests lie in the fields of Insurance Mathematics and Energy Finance. She earned her PhD from the University of Oslo, Norway, and has held academic positions at the University of Cologne, Bielefeld University, and LMU Munich. She is part of the advisory board of the DGVFM (German Society for Insurance and Financial Mathematics).
Professor Maren Diane Schmeck’s research expertise focuses on energy markets, where she examines the impact of factors such as wind and solar power on prices, and develops risk management strategies including the pricing of futures, options, and Power Purchase Agreements (PPAs). In the field of insurance mathematics, she specializes in modeling and managing systematic mortality risk. Additionally, she investigates the use of stochastic clocks in both insurance and finance to quantify catastrophic events and analyze the influence of market activity on prices.
Maren Schmeck is PI in the Research Training Group 2865 “Coping with Uncertainty in Dynamic Economies” and board member of the German Society for Insurance and Financial Mathematics (DGVFM).
She has been awarded research grants supporting research stays at the University of Padua, as well as travel grants for participation in prominent international conferences in the fields of insurance and financial mathematics.
