معرفی
Dr. Hooshyar Assadullahi is a Professor in the School of Mathematics & Physics at the University of Portsmouth, affiliated with the Institute of Cosmology & Gravitation and the Faculty of Technology. He currently serves as Associate Head (Curriculum - Physics). His research focuses on early universe cosmology, particularly non-linear cosmological perturbations and their observational implications. Key interests include non-Gaussianity, gravitational waves, primordial black holes, and stochastic inflation models.
He teaches courses such as Space Science and Applications of Physics, Waves and Optics, and Solid State Physics and Detectors. His work bridges theoretical cosmology with observational data, aiming to elucidate early universe processes and their implications for modern cosmological puzzles like dark energy.
Notable contributions include studies on stochastic inflation beyond slow-roll dynamics, numerical simulations using importance sampling, and the interplay between inflationary models and primordial black hole formation. He collaborates on projects like 'Cosmology, Gravitation and Astrophysics at Portsmouth' and has contributed to datasets on inflationary field content and stochastic processes.
His recent publications explore topics such as noise modeling in stochastic inflation, sudden transitions during inflation, and observational constraints on interacting vacuum energy. He actively supervises research students and engages in interdisciplinary projects, including thin film development through plasma sputtering techniques.
