Willke earned his PhD in 1992 and completed his Habilitation in 2009, both from Leibniz Universität Hannover. He has held academic and research positions continuously since 1993, including Junior Scientist (1993–1997), Senior Scientist (since 1998), and Feodor-Lynen Fellow at Stanford University (1997–1998). His academic title of Apl. Prof. reflects his status as an extraordinary professor.

His primary research interests include laser interferometry, gravitational wave detection, squeezed light, and laser stabilization. He has made significant contributions to the development and commissioning of high-precision laser systems for gravitational wave detectors like GEO600 and Advanced LIGO. His work enables unprecedented sensitivity in detecting spacetime ripples from cosmic events such as black hole mergers.

His recent publications (2022–2025) span major journals including Physical Review D, Classical and Quantum Gravity, and Optics Express. The research trends emphasize detector characterization, quantum noise reduction via squeezed light, laser cavity design (e.g., for ALPS II), and gravitational wave data analysis. These works reflect a strong focus on cutting-edge instrumentation and its application in multi-messenger astrophysics.

Willke has received numerous prestigious awards, recognizing his pivotal role in gravitational wave astronomy:

• Berthold Leibinger Innovation Prize (2023)
• Bruno Rossi Prize (2017)
• Group Achievement Award, Royal Astronomical Society (2017)
• Princess of Asturias Award (2017)
• Gruber Prize (2016)
• Special Breakthrough Prize (2016)

He has held leadership roles in major scientific collaborations, including the LIGO Science Collaboration (since 1997), the GEO Executive Committee (since 2000), and advisory committees for EGO and LIGO. He has delivered lectures on laser interferometry and experimental physics. Although no formal students are listed, his role as group leader implies mentorship of junior researchers and PhD candidates. He has contributed to large-scale funded projects such as Advanced LIGO and GEO600, involving substantial grants from international agencies.

Willke leads the Laser group at the Albert Einstein Institute, which is central to developing and maintaining the laser systems for gravitational wave detectors. The team works on high-power lasers, frequency stabilization, and quantum-enhanced interferometry using squeezed light. They also contribute to next-generation experiments like ALPS II, which searches for axion-like particles using light-shining-through-walls techniques.
