The fascinating physical mechanisms that take place at short timescales and small length scales can enable technologies some of which have yet to be imagined

Research profile

Klaas-Jan Tielrooij is an Associate Professor in the Applied Physics department of Eindhoven University of Technology (TU/e), associated with the Advanced Nanomaterials and Devices group. He is also a Senior Group Leader at the Catalan Institute of Nanoscience and Nanotechnology (ICN2) in Spain. Klaas-Jan leads the Ultrafast Dynamics in Nanoscale Systems group, which partially moved from Spain to the Netherlands in the summer of 2023. See for more information on the group and its research. His key areas of expertise include ultrafast spectroscopy, terahertz photonics, optoelectronics, and layered quantum materials. One of his recent goals has been to reach a fundamental understanding of the transport and dynamics of electronic and phononic heat in 1D and 2D material systems through advanced optical and optoelectronic techniques with high temporal and spatial resolution, and to explore applications in photodetection and thermal management. The group continues to work on quantum materials, studying heat and charge flow, and will also address the conversion of energy and information between various degrees of freedom and across different frequencies. Klaas-Jan has received several prizes, including the FOM Physics Thesis Prize, and competitive grants including an ERC Starting grant (2018), an ERC Proof of Concept grant (2021), and an ERC Consolidator grant (2024).

Academic background

Klaas-Jan Tielrooij received his PhD in 2010 from the University of Amsterdam for studies carried out at AMOLF. He went on to work as a postdoctoral researcher with an NWO Rubicon grant at the Institute of Photonic Sciences (ICFO) in Barcelona, Spain, where he became research fellow in 2014. He also held positions as guest researcher (2015) and visiting professor (2018 – 2020) in Mainz, Germany. In 2018 he became junior group leader at ICN2, Spain, where he was promoted to senior group leader 3.5 years later. In 2022 he was appointed associate professor at TU/e. He is member of the Editorial Boards of the NPG journal Communications Materials and the Wiley journal Advanced Electronic Materials. He has published over 65 peer-reviewed articles and has given over 50 invited talks.

Expertise gerelateerd aan duurzame ontwikkelingsdoelstellingen van de VN

In 2015 stemden de VN-lidstaten in met 17 wereldwijde duurzame ontwikkelingsdoelstellingen (Sustainable Development Goals, SDG's) om armoede te beëindigen, de planeet te beschermen en voor iedereen welvaart te garanderen. Het werk van deze persoon draagt bij aan de volgende duurzame ontwikkelingsdoelstelling(en):

  • SDG 7 – Betaalbare en schone energie
  • SDG 8 – Fatsoenlijk werk en economische groei
  • SDG 12 – Verantwoordelijke consumptie en productie
