Deadline 25 Mar 23:59 CET

Expected start 15 May

This is a full-time (37 hours/week) on-site role located in Aarhus, Denmark for a Postdoctoral Research Fellow at the Department of Computer Science, Aarhus University. This position is for 2 years (24 months) but can be renewed for (up to) an additional year. The start date is May 15th, 2026 – or soon thereafter. The postdoctoral fellow will conduct research on learning theory problems related to algorithms with actionable performance guarantees. More specifically, the research will revolve around the following theme: High probability convergence in stochastic optimization under heavy-tailed noise. Going beyond the canonical sub-Gaussian noise models, the objective is to prove tight convergence rates for first-order or zeroth-order methods when the noise is heavy tailed. This allows us to reliably use the algorithms in practice, when little to no assumptions can be made on the data.

Required Qualifications

• PhD in computer science, mathematics, statistics, or related fields (by the start date).
• Strong background in stochastic optimization, machine learning, or mathematical statistics.
• Track record of publications in relevant journals/conferences (ICML,NeurIPS,ICLR,COLT, Siam Journals, JMLR, COAP, JOTA).
• Ability to work both in cooperation and independently as well as to formulate, verify and execute new ideas.
• Plus : Ability to implement and test algorithms, code and design statistical experiments (preferably with Python).
