Dr. Mohammad Asif Khan
Lead, Bioinformatics

BSc (Singapore), MSc (Singapore), PhD (Singapore)

Dr. Mohammad Asif Khan is currently appointed as the Director of the Perdana University Centre for Bioinformatics (PU-CBi), Assistant Professor to the faculty of the Perdana University Graduate School of Medicine (PUGSOM) and School of Postgraduate Studies (PU-SPS), Malaysia and Visiting Scientist to the Department of Pharmacology and Molecular Sciences, Johns Hopkins University School of Medicine (JHUSOM), USA.

He obtained his Ph.D in Bioinformatics from the National University of Singapore (NUS) in 2010. After a short postdoctoral fellowship at NUS, he was appointed to the faculty of JHUSOM as a Research Associate in the Department of Pharmacology and Molecular Sciences. In 2011, he joined the faculty of PUGSOM as an Assistant Professor in Bioinformatics, with an adjunct Assistant Professor appointment at the same department in JHUSOM till 2014. He also held a Visiting Scientist position at the Immunology Frontier Research Center (iFReC), Osaka University, Japan, under their Young Researchers Program.

Dr. Khan’s broad research interests are in the area of biological data warehousing and applications of bioinformatics to the study of immune responses, vaccines, venom toxins, drug design, and disease biomarkers. Specifically, he is interested in understanding the human-pathogen interactome, defined as the pathogen and human genetic sets (DNA, RNA, Protein) that are directly or indirectly involved in the complex, dynamic interactions between the two, relevant for the survival of each other. He has authored/co-authored a total of 38 published articles ( in various international journals, conferences, and books, and has presented his work at numerous international conferences. His scientific contributions include development of several novel bioinformatics methodologies, tools, and specialized databases, and currently has three patents filed.

Dr. Khan’s teaching experiences have been in bioinformatics, imparting to undergraduate/graduate students at NUS (~1568 students; 2006-2010), and has assisted in the supervision of research projects of more than 50 students (45 bachelors, 6 masters and 3 PhDs). His publications include two bioinformatics pedagogy related journal articles and a book chapter. At PUGSOM, he teaches the bioinformatics components of the Genes to Society Curriculume. He led the development of the programmes and curricula for the Postgraduate Diploma and MSc in Bioinformatics to be taught at the Perdana University School of Postgraduate Studies, through the Centre for Bioinformatics. Furthermore, the School now also offers PhD in Health, with the option for specialisation in Bioinformatics.

Dr. Khan is currently the ExCo Vice President (Corporate) for the Asia-Pacific Bioinformatics Network (APBioNet) and a Honorary Director for APBIoNet Public Limited. He is also a member of the International Society for Computational Biology (ISCB). His services to the scientific community include as a reviewer for journals, conferences, and funding agencies, and is active in the organization of local and international bioinformatics conferences, meetings and workshops.
