Dr Abdullah Tarik Aslan is an internal medicine physician who graduated from Hacettepe University Faculty of Medicine as a high honour student in 2014 and completed his internal medicine training program at Hacettepe University Faculty of Medicine in 2019. He completed his obligatory duty as an internist in Burdur (a city located in southwest part of Turkey). During his career, he has worked with several important research groups. He performed a one-month observership activity at Hospital Universitario Virgen Macarena, Seville, Spain by endorsement of ESCMID (European Society of Clinical Microbiology and Infectious Diseases) in 2019. He also worked in Prof. Nordmann’s laboratory in Fribourg/Switzerland. Abdullah is still leading several projects with Prof. Murat Akova’s group in Turkey.

Abdullah is currently undertaking a PhD under the supervision of Professor David Paterson and Dr. Patrick N Harris. He is scholarly interested in clinical and molecular epidemiology of infections caused by antimicrobial resistant bacteria, pragmatic clinical trials, target trials, novel antimicrobials, synergistic interactions between antimicrobial agents, artificial intelligence and machine learning.

Abdullah has been awarded numerous awards and grants, such as the high honour student award of Hacettepe University, Pfizer Investigator Sponsored Research (Pre-clinical) grant, Pfizer Investigator Sponsored Research (Non-interventional Clinical) grants and an ECCMID Travel Grant. He has been invited to speak at national and international conferences, has published over 20 peer-reviewed manuscripts.
