Jan Hamann

Dr. Jan Hamann is a Senior Lecturer at the School of Physics, University of New South Wales, specializing in theoretical cosmology. His research focuses on analyzing high-precision astrophysical observations to study the universe's history, composition, and inflationary models.

• Education: PhD in Cosmology from Hamburg University (2007)
• Research Interests: Cosmic Microwave Background (CMB) analysis, inflationary features, dark matter (sterile neutrinos), cosmological parameter estimation, and machine learning applications to astrophysical data.
• Supervision: Primary supervisor for PhD students Yuqi Kang, Julius Wons, and Nathan Cohen; secondary supervisor for Kai Yi; and Honours supervisor for Jahanvi Maheshwari.
• Teaching: Courses include PHYS1241 Higher Physics 1B (Special), PHYS4143 General Relativity, and PHYS3115 Particle Physics and the Early Universe.

Recent publications (2024–2017) address CMB lensing, inflationary model optimization, sterile neutrino constraints, and machine learning techniques for cosmological data. He has contributed extensively to Planck mission analyses, particularly in CMB power spectra, isotropy tests, and inflationary parameter constraints.
